Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If average control parameters are used for all vehicles, then device complexity is reduced and ease of manufacture is improved, but adaptability to specific journey conditions deteriorates
Solution Approach 1:
The system generates and applies customized control parameters specific to each vehicle's journey conditions and user constraints. By changing the control parameters from average standardized values to customized values optimized for specific journeys (considering factors like fuel consumption priority, emission constraints, and route characteristics), the system resolves the contradiction between ease of manufacture and adaptability.
2Adaptability or versatility
If customized control parameters are generated for each journey, then adaptability to specific constraints is improved, but device complexity and data processing requirements increase
Solution Approach 1:
The system introduces an intermediary computation means (server or onboard computer) that generates customized control parameters by processing journey data and constraints. This intermediary handles the complex data processing and parameter optimization, allowing the electronic control device to achieve high adaptability without requiring the device itself to be overly complex. The computation means acts as a mediator between the user's constraints and the control device's parameters.
3Device complexity
If computation means are located remotely from the vehicle, then device complexity onboard is reduced, but communication requirements and data exchange needs increase
Solution Approach 1:
The system extracts the complex computation means from the vehicle and locates it remotely on a server. This extraction reduces the device complexity onboard the vehicle, as the heavy computational workload for generating customized parameters is performed externally. The server handles the complex data processing, journey simulation, and parameter optimization, while the vehicle only needs to exchange necessary data through communication means.
4Ease of operation
If average parameter values are used, then ease of operation is improved, but productivity and fuel consumption optimization deteriorate
Solution Approach 1:
The system performs preliminary action by generating customized control parameters before the vehicle's journey begins. The computation means simulates the journey, processes user constraints, and determines optimized parameters in advance. This preliminary parameter customization allows the vehicle to operate efficiently from the start of the journey, improving productivity and fuel consumption without requiring complex real-time adjustments during operation.
