Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vehicle control requests from different applications are individually instructed to the vehicle, then each application can provide its service, but interference between vehicle controls occurs leading to suboptimal control
Solution Approach 1:
The patent introduces a remote control management device as an intermediary between multiple applications and the vehicle. This mediator receives control requests from multiple applications, performs arbitration to determine execution order and compatibility, and then transmits the arbitrated requests to the vehicle. This resolves the contradiction by enabling multiple services while preventing harmful interference through centralized coordination.
Solution Approach 2:
The patent implements preliminary arbitration of control requests before they are executed on the vehicle. The remote control management device evaluates multiple requests in advance, determines their compatibility and execution order, and only then transmits the arbitrated requests to the vehicle. This preliminary action prevents interference from occurring in the first place.
2Speed
If multiple vehicle control requests are transmitted simultaneously to the vehicle, then service response time is reduced, but control interference and safety risks increase
Solution Approach 1:
The remote control management device serves as a mediator that receives multiple control requests simultaneously, evaluates their compatibility and urgency, determines the optimal execution order, and then transmits them to the vehicle in a safe sequence. This maintains fast response while preventing harmful interference.
Solution Approach 2:
The patent changes the parameter of request transmission from simultaneous to sequential based on arbitration results. The management device assigns different transmission timings and priorities to different requests based on their compatibility and urgency, optimizing both response time and safety.
3Reliability
If arbitration of vehicle control requests is implemented, then control safety and optimality are improved, but system complexity increases
Solution Approach 1:
The remote control management device performs multiple functions: receiving requests from multiple applications, evaluating compatibility, determining execution order, and transmitting arbitrated requests to the vehicle. By consolidating these functions in a single multi-functional device, the patent avoids the need for multiple separate arbitration systems, thereby reducing overall complexity while maintaining safety.
4Device complexity
If control requests are individually processed without arbitration, then system complexity is reduced, but control optimality and safety deteriorate
Solution Approach 1:
The remote control management device acts as an efficient intermediary that streamlines the control request processing. Instead of complex individual processing for each request, the mediator provides centralized arbitration that optimizes the execution order and compatibility of multiple requests, improving control efficiency without excessive complexity.
