This project studies how a purely mechanical fixture can adapt to part variation without human intervention or complex electronics. It examines linkages, springs, cams, and compliant mechanisms that respond to geometry changes during loading. As factories shift toward small batch and custom production, fixed tooling becomes a limitation. This project asks how mechanics alone can bring adaptability back to the shop floor while keeping systems simple and dependable.

7. Predictive Maintenance System Using Vibration Patterns

The predictive maintenance system using vibration patterns moves beyond the idea of machines as silent tools and treats them as physical systems that constantly communicate their condition through motion. Every rotating or sliding component carries a vibration signature shaped by alignment, wear, lubrication, and load. This project studies how changes in vibration behavior precede visible failure in bearings, gears, shafts, and couplings. Instead of reacting to breakdowns, the system allows maintenance decisions based on early mechanical signals. The project also raises a broader reflection on how engineers interpret motion as information and how neglecting such signals leads to waste, downtime, and safety risk. It encourages students to view maintenance not as repair work, but as an extension of mechanical understanding and responsibility.

8. Reconfigurable Assembly Workstation for Small Manufacturers

The reconfigurable assembly workstation for small manufacturers explores how physical workspaces can adapt as quickly as production needs change. Instead of fixed tables and layouts, this project requires that production needs change. Instead of fixed tables and layouts, this project designs modular frames, adjustable supports, and movable tooling that workers can rearrange without heavy equipment. It responds to the reality that small manufacturers cannot afford frequent shutdowns for layout changes. The project asks how mechanical design can protect jobs, reduce strain, and support growth without increasing cost or complexity.

9. Modular Conveyor System with Mechanical Fault Isolation

Traditional conveyors shut down entirely when one section fails, creating widespread disruption. This project designs conveyor modules that mechanically isolate faults through clutches, overrunning drives, or disengaging links. It explores how systems can fail locally instead of globally. The idea pushes students to think about resilience, containment, and recovery as mechanical design goals rather than afterthoughts

Advanced Mobility and Transportation Systems

10. Lightweight Chassis Design  for Electric Micro-mobility Vehicles

The lightweight chassis design for electric micro-mobility vehicles examines how structural decisions shape the viability of small electric transport systems such as e-scooters, e-bikes, and neighborhood vehicles. Because battery capacity remains limited, every kilogram of structural mass directly affects range, stability, and cost. This project studies material choice, load paths, joint design, and frame geometry to achieve strength with minimal weight. Beyond structural analysis, it raises a broader question about how mechanical engineers can support dense urban mobility without copying the heavy designs of conventional vehicles. The work encourages students to think about structural honesty, where material exists only where loads demand it, and to view lightweighting as a responsibility rather than an optimization exercise.

11. Regenerative Suspension System for Urban Roads\

The regenerative suspension system for urban roads challenges the idea that road-induced vibrations must always be wasted as heat. Urban roads subject vehicles to constant small-amplitude motion through bumps, joints, and uneven surfaces. This project studies a suspension system that captures part of this motion and converts it into usable mechanical or electrical energy while still maintaining ride comfort and control. It examines spring-damper behavior, energy conversion mechanisms, and trade-offs between comfort and recovery. The deeper question lies in whether everyday disturbances can become resources instead of losses. This project lets you rethink suspension systems as active contributors to energy management rather than passive comfort components.

12. Mechanical Cooling System for Battery-driven Vehicles

The mechanical cooling system for battery-driven vehicles focuses on the silent but critical issue of thermal control in electric mobility. Battery performance, life, and safety depend strongly on temperature uniformity and heat removal. This project studies air-based or liquid-assisted mechanical cooling systems that rely on geometry, airflow control, and heat transfer rather than heavy electronic intervention. It examines duct design, fan placement, heat sink geometry, and passive airflow paths created by vehicle motion. At a conceptual level, the project asks how much thermal stability can be achieved through mechanical intelligence alone. It encourages students to treat heat as a design constraint that shapes the entire vehicle rather than a problem addressed at the final stage.

13. Aerodynamic Study of Compact Delivery Vehicles

The aerodynamic study of compact delivery vehicles looks at how airflow affects energy use in short-range logistics vehicles that operate at moderate speeds but high daily duty cycles. While aerodynamics receive attention in high-speed vehicles, compact delivery platforms suffer from inefficient shapes, frequent stops, and add-on cargo boxes that increase drag. This project studies airflow behavior, pressure zones, and wake formation around compact vehicle bodies using scaled models or simulations. It encourages students to think about aerodynamics as a cumulative energy issue rather than a speed problem. The work connects design geometry to energy use, range extension, and operation cost in last-mile delivery systems.
