Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling module is tilted to improve cooling effect, then the cooling efficiency is improved, but the difficulty to mount the cooling module to the frame increases
Solution Approach 1:
The cooling module mounting system is divided into separate components: the cooling module itself, the frame, and diagonal brackets that serve as connectors. This segmentation allows the cooling module to be tilted for optimal cooling while the brackets handle the mounting complexity, resolving the contradiction between cooling efficiency and mounting difficulty.
Solution Approach 2:
The patent introduces diagonal brackets that extend in both longitudinal and lateral directions, adding a dimensional aspect to the mounting structure. This diagonal configuration allows the cooling module to be positioned at an optimized angle for cooling while maintaining secure attachment to the frame, thus improving cooling efficiency without excessively increasing mounting difficulty.
2Length of moving object
If the front overhang is shortened for microcompact vehicle design, then the vehicle size is reduced, but the impact-absorbing space becomes insufficient
Solution Approach 1:
The patent employs diagonal members that extend in both longitudinal and lateral directions, utilizing three-dimensional space more effectively. This diagonal configuration allows for compact longitudinal dimensions while maintaining adequate impact absorption capacity through the lateral extension and strategic positioning of structural members.
Solution Approach 2:
The front end module frame uses asymmetric diagonal members positioned at specific angles and locations to optimize both compactness and impact absorption. The diagonal members are strategically placed to provide structural support and energy absorption in the shortened front overhang configuration, resolving the contradiction between reduced vehicle size and impact protection.
3Ease of manufacture
If the cooling module is mounted vertically, then the mounting is simple, but the air contact surface area is reduced and cooling effect decreases
Solution Approach 1:
The patent transitions from a simple vertical mounting to a diagonal configuration that utilizes both longitudinal and lateral dimensions. The diagonal brackets enable the cooling module to be positioned at an optimized angle, increasing the air contact surface area and improving cooling effect while maintaining reasonable mounting complexity through the use of standardized bracket components.
