Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a modular sensor mounting device with support elements is used, then the sensor can be securely mounted with stable position, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The sensor mounting device is divided into separate functional components: a sensor holder for positioning, support elements for securing, and a retaining spring device for locking. This segmentation allows each component to perform its specific function independently, simplifying the overall installation process while maintaining stable sensor mounting.
Solution Approach 2:
The retaining spring device introduces a dynamic element to the otherwise static mounting structure. The spring mechanism allows for easy engagement and disengagement of the sensor, transforming a complex multi-step installation into a simple snap-in operation that maintains stable positioning once mounted.
2Measurement precision
If extensive environmental sensors are installed for driver assistance systems, then the accuracy of vehicle surroundings detection is improved, but the installation and alignment process becomes more error-prone
Solution Approach 1:
The sensor holder is pre-configured with specific geometric features and positioning elements that automatically guide the sensor into the correct position during installation. This preliminary preparation of the mounting structure ensures proper alignment and reduces installation errors, allowing multiple sensors to be installed accurately without requiring complex alignment procedures.
3Ease of repair
If a retainer spring device is used to hold the sensor, then the sensor can be easily removed during service work, but the mounting structure becomes more complex
Solution Approach 1:
The retaining spring device combines multiple functions into a single component: it provides mechanical retention to hold the sensor, incorporates a locking mechanism for secure mounting, and includes release features for easy removal during service. This merging of functions into one integrated device achieves ease of repair without significantly increasing overall structural complexity.
