Why Systems Engineering in Chute Design?

 Systems Chute Design

  • Mining chutes (e.g. ROM bin discharge, conveyor transfers, load-out stations) are critical bottlenecks in coal handling.

  • Failures often occur not because of poor fabrication, but because of system-level oversights — dust control, maintainability, wear-life, flow interactions.

  • A systems engineering lens highlights the importance of considering the whole coal-handling chain, stakeholder requirements, and lifecycle impacts.

Stakeholder Requirements and Context

  • Mine operators: Need reliability, minimal downtime, low maintenance costs.

  • Maintenance teams: Need safe access, modular liners, simple replacement.

  • Environmental stakeholders: Dust suppression, spillage control.

  • Design/fabricators: Need practical geometries and materials suited to coal flow.

  • Regulators/community: Noise, dust, and safety compliance.

Here you can apply the V-model or a requirements traceability matrix to show how system needs cascade into chute geometry, materials, and installation.



System Integration

  • Upstream/Downstream interactions: Coal size distribution, moisture content, conveyor speeds, and bunker pressures all affect chute performance.

  • Interface management: Chute design cannot be isolated — must integrate with feeders, crushers, screens, conveyors.

  • System-of-systems: The chute is a subsystem within the broader materials handling system; optimisation requires flow modelling (DEM, CFD).

Lifecycle Engineering

  • Design for maintainability: Bolt-in wear liners, modular chute sections.

  • Reliability-centred design: Anticipating failure modes (blockages, excessive wear, dust plumes).

  • Lifecycle cost analysis: Weighing upfront fabrication vs. long-term downtime costs.

  • Refurbishment strategies: How companies like HIC Services approach extending system life.

Modelling and Verification

  • Modelling tools: DEM (Discrete Element Method) for coal particle trajectories; CFD for dust and air entrainment.

  • Verification & validation: Linking lab-scale tests (TUNRA Bulk Solids) with real plant performance.

  • Iterative design: Prototyping in simulation before fabrication reduces system-level risk.

Case Studies (Hunter Valley Examples)

  • A new build chute by T.W. Woods (focus on heavy-duty fabrication and commissioning).

  • An optimisation study by Chute Technology (DEM-driven redesign to reduce blockages).

  • A maintenance rebuild by HIC Services (liner replacement strategy for lifecycle extension).

  • A research contribution by TUNRA Bulk Solids (fundamental bulk solids testing feeding into design).

Each illustrates different systems engineering principles: requirement analysis, integration, lifecycle thinking, verification.

  • Coal chute design is a microcosm of systems engineering: multiple stakeholders, competing objectives, and lifecycle considerations.

  • By framing it this way, engineers can avoid "patch-and-fix" thinking and deliver sustainable, reliable designs that serve the whole system.

Robotics and Human Relations: Risks, Ethics, and the Path Forward

 



Introduction

The rapid integration of robotics into industrial workplaces has transformed the way humans engage with machines. While robots promise efficiency, consistency, and relief from hazardous tasks, their deployment also exposes workers to new risks. Two recent incidents illustrate the dual-edged nature of this technological advancement: the alleged robotic arm attack in a Tesla facility, where a worker filed a lawsuit after suffering severe injuries, and the fatality in a Wisconsin pizza factory, where a worker was crushed by a robotic machine (People, 2025; New York Post, 2025). These tragedies highlight the urgent need to reexamine the relationship between humans and robots—not only from a technical standpoint but also from ethical, legal, and organizational perspectives.

This essay will explore the rise of robotics in industrial contexts, analyze the human-robot relationship, discuss the Tesla and Wisconsin cases as case studies, and evaluate the ethical and safety frameworks necessary to ensure a future where human dignity and safety are preserved.

The Rise of Robotics in Industry

Industrial robotics has become a cornerstone of global manufacturing and logistics. Robotics applications span across sectors such as automotive production, food processing, aerospace, and warehousing. According to the International Federation of Robotics (IFR, 2024), global robot installations grew by 7% in 2023, reflecting increasing reliance on automation. Companies adopt robotics for cost savings, operational efficiency, and the ability to perform repetitive or dangerous tasks that are less suitable for humans.

Yet, the accelerated adoption of robotics is not without drawbacks. Incidents such as mechanical failures, software errors, or improper human interaction expose workers to injuries that were previously less common. Moreover, small to mid-sized enterprises, which may lack robust safety infrastructures, increasingly incorporate robotic systems, amplifying risks in less regulated environments.

Human–Robot Relations: Collaboration and Tension

The field of human–robot interaction (HRI) examines how people and machines share workspaces. Traditional industrial robots are typically separated from humans by cages or barriers, while newer “collaborative robots” or cobots are designed to interact directly with workers (Dautenhahn, 2007). Cobots rely on sensors and AI-driven systems to avoid collisions, but their efficacy depends heavily on maintenance, programming accuracy, and operator training.

Trust plays a central role in human–robot relations. Research suggests that when workers trust robotic systems, productivity and safety outcomes improve (Hancock et al., 2011). However, misplaced trust—such as assuming a machine will always stop when necessary—can result in catastrophic accidents. Thus, tension arises between the promise of robotics as partners and the reality of machines as unpredictable hazards.

Case Study 1: Tesla Robotic Arm Lawsuit

The lawsuit filed by a former robotics technician against Tesla alleges that while disassembling a robotic arm, the machine unexpectedly moved, striking him, knocking him unconscious, and causing severe injuries (People, 2025). The case raises pressing questions regarding lockout/tagout (LOTO) procedures, which require energy sources to be isolated before servicing equipment (OSHA, 2023). If procedures were not followed or if the robotic system lacked sufficient interlocks, accountability may fall both on the company and the machine designers.

Beyond technical failure, the Tesla case highlights the blurred line of liability in human–robot relations. Was the fault due to human error, insufficient safety protocols, or a machine malfunction? The case underscores the legal complexity of attributing responsibility when humans and robots interact in shared spaces.

Case Study 2: Wisconsin Pizza Factory Fatality

In September 2025, a worker at a Wisconsin pizza production facility was killed after being crushed by a robotic machine (New York Post, 2025). Unlike Tesla, which operates at the frontier of automation, this incident occurred in a food-processing environment—illustrating the diffusion of robotics beyond advanced manufacturing.

Smaller facilities may lack the rigorous safety oversight common in larger corporations. Reports suggest that training, maintenance, and adequate guarding were insufficient. The tragedy illustrates that as robotics adoption expands, systemic issues such as cost-cutting, inadequate regulatory enforcement, and lack of expertise increase the likelihood of fatal outcomes.

Ethical Dimensions of Human–Robot Relations

The ethical implications of robotics in industry extend beyond safety compliance. When robots harm humans, questions of moral responsibility emerge. Is it the employer, the manufacturer, or the software developer who bears ultimate responsibility? (Borenstein & Pearson, 2010).

Workers also experience psychological consequences. The fear of injury, job displacement, and dehumanization are common themes in workplaces where machines dominate. Studies indicate that poor human–robot integration can lead to stress, job dissatisfaction, and mental health risks (ÄŒaić et al., 2019). Ethical frameworks must therefore address not only physical safety but also the broader well-being of workers.

Designing Safer Human–Robot Futures

The path forward requires multi-layered strategies:

  1. Engineering Safeguards: Robots should be equipped with advanced sensing technologies, fail-safes, and emergency stop mechanisms. AI-driven predictive maintenance can reduce the chance of catastrophic failures.

  2. Procedural Safeguards: Employers must rigorously implement OSHA’s LOTO standards and other safety protocols, ensuring that servicing robots is never conducted without proper isolation.

  3. Organizational Safeguards: A robust safety culture that empowers workers to report hazards without fear of retaliation is essential. Safety training must be continuous, not a one-time exercise.

  4. Regulatory Oversight: Governments and standards organizations must strengthen oversight, especially for small and medium-sized enterprises. International standards such as ISO 10218 (safety requirements for industrial robots) should be adopted widely.

  5. Ethical Innovation: Robotics designers should incorporate human-centered design principles, ensuring that machines are not only efficient but also aligned with human safety and dignity. Transparency in AI-driven robotics decision-making is crucial for trust.

Conclusion

The incidents at Tesla and in Wisconsin serve as stark reminders that the integration of robotics into industrial settings is a double-edged sword. While robots promise efficiency and safety in theory, the reality is that human workers remain vulnerable to errors, oversights, and systemic failings. The relationship between humans and robots must therefore be reframed: not as a contest between man and machine, but as a partnership requiring ethical foresight, robust safety mechanisms, and regulatory vigilance.

Ultimately, the future of robotics and human relations lies in balance. As automation reshapes industries, society must ensure that technological progress does not come at the expense of human life or dignity. By embedding safety, ethics, and accountability into every stage of robotics deployment, we can chart a path where humans and machines work not in tension, but in harmony.

Plant Design

Whether you’re planning to design, build or renovate a plant, you can benefit from using 3D visualization tools across your project. 3D layouts offer an organized approach, whereby multiple vendors and teams can collaborate and communicate their specific needs.

3D visuals allow vendors to visualize plant design in a way that’s not possible with 2D. This ensures that problems in the design are found early, preventing delays and expenses associated with making changes later in development.


Creating 3D visualisations of your plant layout designs promotes a visual workflow that can assist in managing external vendors, track design revisions and pinpoint areas of concern before they arise.

At Hamilton By Design, we can help to define your plant layout and put together a 3D layout that allows you to communicate clearly and effectively. With over 20+ years of experience, we are confident that we can be of value to your team, regardless of your timings, budget or industry.

Hamilton ByDesign - The Solidworks Experience


To our clients it is, our plan is to leverage the strength and capabilities of the Dassault Systèmes 3DExperience Platform and build a new experience that is as intuitive and easy to use as the SolidWorks tools you use today. Today, I want to share the first example of this new approach, which we are calling SolidWorks Mechanical Conceptual.

SolidWorks Mechanical Conceptual is a tool for conceptual mechanical design that is complementary to the products you use today. It allows you to capture ideas digitally, quickly create 3D concept models, get feedback from internal and external stakeholders, and easily manage multiple concepts before committing engineering time to build.

Why Conceptual?


  •     31% of project time is spent on conceptual mechanical design
  •     3 out of 4 engineers are engaged in conceptual mechanical design
  •     On average there are six conceptual and four design iterations in a typical project
  •     There can be more than three internal and two external stakeholder groups involved in the concept phase


Today, SolidWorks is the best solution for detail design, but it limits your creativity for this key conceptual step.  SolidWorks Mechanical Conceptual fills in these gaps and allows you to:


  •     Capture ideas digitally
  •     Manage multiple concepts
  •     Collaborate and communicate


Instinctive Design

Evolving a concept is where SolidWorks Mechanical Conceptual really begins to speed the design time.  Most systems force you to think about product structure in order to capture ideas. Our single modelling environment is about ease of use, creativity, and ease of change – with amazing flexibility. Capturing concepts digitally is quick and easy with familiar tools and concepts so the focus is on ideas -- not on the software.

Sketch

SolidWorks Mechanical Conceptual merges the benefits of history, parametrics, and direct editing into a single interface.  As a concept evolves, you can make any change necessary to a design while respecting the design intent you previously created. The Single Modelling Environment allows you to evolve from layout sketches to 3D geometry, to separate parts and assemblies, without taking product structure into consideration.

SolidWorks Mechanical Conceptual lets you evolve your design’s organizational structure as you evolve the idea and have a better understanding of where the design will go.  This eliminates wasted time because you never have to start over or drastically rework designs to make an underlying change.

Search Assemble

In our single modelling environment, as we evolve our product structure into assemblies we have familiar tools and intelligence that improves with use as components learn how they were used previously. You can also automatically apply previous intent to new designs. And SolidWorks Mechanical Conceptual always saves the design, as well as various iterations, so it’s very easy to get back to a previous idea and develop it further.

As we get to more of a 3D concept, we can use motion simulation to better understand the real world interaction of parts and identify key concerns early on, before getting to detail design.


Social Innovation

When you feel that sufficient concepts have been captured, then it’s key to be able to engage stakeholders (both internal to the organization as well as with customers and vendors) to get feedback on the best path forward.

SolidWorks Mechanical Conceptual has social innovation capabilities built into its foundation.  At any point, the designer can engage stakeholders by posting concepts to their private communities. Stakeholders are notified that there is a concept to review and can provide feedback using simple and familiar Web concepts.   The world is becoming more social every day, and at SolidWorks we believe in collective intelligence. SolidWorks Mechanical Conceptual truly brings these capabilities to concept design.  This type of participation will allow you to better engage with your customers and differentiate yourself from the competition.  After stakeholders are done, the designer is automatically notified and can continue to evolve the concept with this feedback.

Connected

SolidWorks Mechanical Conceptual is always connected to the design database and to other users.  This gives us the ability to secure your data, prevent data loss from any crashes, and automatically save iterations of each concept.

You are also connected to other users both working on your project and also in the wider SolidWorks community.  You can participate in live chats with other users to get feedback on a question or a design challenge.  Users are always working together on the same design so that there is no time wasted, or confusion as to what is the latest version.  When a team member makes a change, all users are updated in real time with the latest version so the concepts will always progress forward.

Communities

Being connected provides access anywhere at any time to your concepts.  SolidWorks Mechanical Conceptual even allows users to take designs on the go for design reviews, or even for sales and marketing using mobile applications.

We are very excited about the progress we have made with SolidWorks Mechanical Conceptual.  This product will be a great complement to companies using SolidWorks today.  We believe the product delivers on a new approach to conceptual design by incorporating the flexibility of a single modelling environment, social innovation, and the benefits of being connected online.

In May of this year, we will be working with select customers to validate these principles of conceptual design in their production environments.  Once we are confident in the benefits these customers are seeing we expect to make SolidWorks Mechanical Conceptual available to all users in the Fall of 2013.

The team at Hamilton By Design have been using Solidworks since 2001for more information on how to get your projects moving contact HamiltonBy Design Today
