Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle seat operation modules are used as a motion base for VR simulation, then a new entertainment experience and vehicle productivity are improved, but existing vehicles lack the integrated control environment and wireless communication capability required for implementation
Solution Approach 1:
The control unit is designed to perform multiple functions: it controls the seat operation modules (power seat, lumbar support, seat heating/cooling) and simultaneously manages VR simulation operations. This multi-functionality allows the vehicle's existing seat control system to serve dual purposes - traditional seat adjustment and VR-based motion simulation - without requiring completely separate control systems.
Solution Approach 2:
The patent combines the VR equipment control with the existing seat control system by integrating both into a single control unit. The control unit receives commands from both the VR equipment and user input devices, and coordinates the operation of seat modules accordingly. This merging reduces system complexity compared to having separate independent control systems for VR and seat operations.
2Productivity
If VR equipment is integrated with vehicle seat modules, then synchronized VR image and seat movement is achieved, but wireless communication capability must be implemented
Solution Approach 1:
The control unit acts as an intermediary between the VR equipment and the seat operation modules. It receives signals from the VR equipment indicating desired motion states, processes these signals, and translates them into appropriate commands for the seat modules. This intermediary role enables synchronized operation without requiring direct complex communication protocols between VR equipment and each individual seat module.
Solution Approach 2:
The system implements feedback mechanisms where the control unit continuously monitors the state of seat modules and adjusts control signals to maintain synchronization with VR images. The control unit receives real-time information about seat position and movement, and uses this feedback to coordinate with VR equipment to ensure synchronized operation, improving reliability of the simulation experience.
