Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different shapes of solar radiation sensors are mounted directly on the vehicle interior material, then each sensor shape requires a dedicated mounting hole design, but this increases the number of molds needed and reduces manufacturing efficiency
Solution Approach 1:
The attachment is designed with a universal mounting structure that can accommodate different shapes of solar radiation sensors through a standardized interface. The attachment includes an abutment plate portion with an insertion hole and retaining portions that engage with the sensor body, allowing various sensor shapes to be mounted on the same vehicle interior material without requiring different mounting hole designs.
Solution Approach 2:
The attachment serves as an intermediary component between the vehicle interior material and the solar radiation sensor. It includes an abutment plate portion that interfaces with the mounting hole in the vehicle interior material, and retaining portions that secure the sensor body, thereby mediating the connection between different sensor shapes and a standardized mounting location.
2Ease of operation
If the abutment plate portion is made small enough to insert into the mounting hole, then it can be mounted directly, but it cannot provide sufficient support for the sensor head portion
Solution Approach 1:
The attachment is segmented into distinct functional portions: an abutment plate portion with dimensions that allow insertion into the mounting hole but prevent passage through, and retaining portions that extend from the back side to secure the sensor body. This segmentation allows each portion to fulfill its specific function - the abutment plate provides mounting interface while the retaining portions provide secure attachment.
Solution Approach 2:
The attachment utilizes dimensional constraints by making the abutment plate portion have a size that permits insertion into the mounting hole from the front but prevents passage through to the back side. The retaining portions extend in the thickness direction to engage with the sensor body, creating a multi-dimensional mounting solution that provides both insertability and support strength.
3Device complexity
If the mounting structure is simplified to reduce complexity, then manufacturing becomes easier, but the securing reliability of the sensor decreases
Solution Approach 1:
The attachment is divided into functional segments - the abutment plate portion that interfaces with the mounting hole and the retaining portions that secure the sensor - allowing a relatively simple overall structure that achieves reliable mounting through proper functional division.
Solution Approach 2:
The retaining portions are designed to be elastically displaceable, allowing them to automatically engage with the sensor body through elastic deformation during insertion, providing secure attachment without requiring additional fastening operations or complex locking mechanisms.

AI summary
An attachment includes an abutment plate portion and a retaining portion. The abutment plate portion cannot be inserted into a mounting hole. The abutment plate portion includes an insertion hole in a middle portion thereof. The retaining portion is disposed on a back side of the abutment plate portion. The attachment is mounted on the mounting hole by the retaining portion inserted into the mounting hole, the abutment plate portion abutted against a peripheral edge portion of the mounting hole from a front side and a lock portion of the retaining portion engaged with the peripheral edge portion of the mounting hole from a back side. A body portion of a solar radiation sensor is inserted into the insertion hole, a head portion of the solar radiation sensor is abutted against the abutment plate portion and at least one catch claw of the body portion of the solar radiation sensor is engaged with the lock portion of the retaining portion.
