Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VR service is provided in a stopped vehicle using the vehicle as a motion platform, then the simulated experience quality is improved, but the electric power consumption increases significantly
Solution Approach 1:
The operation management apparatus performs preliminary calculation of remaining charge and travelable distance before the VR service starts. This allows the system to assess power consumption implications in advance and provide informed operation management information to the user, enabling them to make decisions about whether to proceed with the VR service based on the calculated power requirements and remaining battery capacity.
2Power
If high power is consumed during VR service, then the VR experience quality is improved, but the remaining battery charge decreases, risking vehicle immobility
Solution Approach 1:
The operation management apparatus provides feedback to the user by presenting operation management information including remaining charge and travelable distance calculations. This feedback loop allows the system to monitor power consumption implications and inform users about the impact on vehicle operability, enabling informed decisions about VR service usage while maintaining awareness of vehicle power status.
Solution Approach 2:
The system calculates remaining charge and travelable distance before the VR service commences, providing preliminary assessment of power consumption impacts. This preliminary action enables the system to warn users in advance if the VR service would leave insufficient charge for vehicle operation, allowing users to adjust settings or postpone the service to maintain vehicle operability.
3Adaptability or versatility
If the vehicle is used as a motion platform for VR, then the immersive experience is enhanced, but the battery charge depletes rapidly
Solution Approach 1:
The operation management apparatus performs preliminary calculations of remaining charge and travelable distance before the VR service begins. This advance assessment allows the system to inform users about the expected power consumption and its impact on battery duration, enabling them to make informed decisions about whether to proceed with the immersive VR experience or adjust settings to conserve battery charge.
Solution Approach 2:
The system provides feedback to users about battery charge status and travelable distance implications of using the vehicle as a motion platform. This feedback mechanism allows users to understand the trade-off between immersive experience quality and battery duration, enabling them to make balanced decisions about VR service usage while maintaining adequate vehicle operability.

AI summary
The operation management apparatus of a moving body is included in a virtual space production apparatus that includes an AV device configured to provide AV information to an occupant of the moving body, an SUS actuator configured to generate load relating to vibration of the moving body, and a VR controller configured to control the AV device and the SUS actuator and that produces a simulated experience for the occupant in a virtual space by driving the AV device and the SUS actuator when a VR service according to VR contents is enjoyed by using the moving body in a stopped state. The VR controller presents operation management information relating to a remaining charge of a battery and a travelable distance after enjoying of the VR service according to the VR contents, on an LCD prior to the enjoying of the VR service.
