Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle control system incorporates advanced driving assistance, electrification, and diversifying cockpit experiences, then the functional capabilities of the vehicle are improved, but the complexity of the control system and the number of control devices increase
Solution Approach 1:
The patent implements a standardized shell design that can accommodate multiple different control devices and functional circuits. The shell includes standardized connector positions and mounting structures that allow various control modules to be integrated into a unified platform, reducing the need for separate redesigns for different functions.
Solution Approach 2:
The control system is divided into modular control devices, each with specific functions, that can be independently designed and then integrated into the standardized shell. This segmentation allows for easier management of complexity while maintaining versatility.
2Adaptability or versatility
If the shell is re-designed according to different functional requirements, then the adaptability to different functions is improved, but the manpower, material resources and time costs increase
Solution Approach 1:
A universal shell design is provided that includes standardized connector positions, mounting structures, and internal layouts that can accommodate multiple different control devices. This allows the same shell to be used across different functional requirements without redesign, significantly reducing development time and resources.
Solution Approach 2:
The shell is designed in advance with predetermined connector positions and mounting structures that are optimized for multiple functions. This preliminary action of creating a versatile platform before specific applications eliminates the need for subsequent redesigns.
3Adaptability or versatility
If the shell is re-designed according to different functional requirements, then the functional adaptability is improved, but the manpower and material resources consumption increase
Solution Approach 1:
The standardized shell design enables a single manufacturing process to produce shells that can accommodate multiple different control devices. This universality reduces the need for multiple specialized manufacturing lines, tooling, and materials, thereby lowering overall production resource consumption.
Solution Approach 2:
Multiple functional requirements are merged into a single shell design platform. By combining the capabilities to accommodate different control devices into one standardized shell, the patent eliminates redundant manufacturing efforts and resource consumption associated with producing separate shells for each function.

AI summary
A vehicle control device for shell sharing between control modules comprises a first control module and a second control module. The first control module comprises a plurality of first connectors, a first circuit board, and a first controller arranged in a second area of the first circuit board. The second control module comprises a plurality of second connectors, a second circuit board, and a second controller arranged in the fourth area of the second circuit board. By setting the size of the first circuit board and the second circuit board to be consistent, the number and type of the first connectors and the second connectors to be consistent, and the second area of the second circuit board corresponding to the first area of the first circuit board is set, the shell structure of the first control module and the second control module can be shared. A vehicle is also provided.
