Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex multi-part fastening devices are used to securely attach electronic devices, then the attachment reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The fastening device is divided into a base plate and separate holding elements. The holding elements can be rigid or movable, with the movable ones being elastically displaceable relative to the base plate. This segmentation allows each component to perform its specific function while simplifying the overall structure compared to complex multi-part devices.
Solution Approach 2:
The base plate integrates multiple functions: it provides the mounting surface, contains mounting openings for vehicle integration, and serves as the reference structure for the holding elements. This merging of functions reduces the number of separate components needed while maintaining attachment reliability.
2Manufacturing precision
If precise positioning mechanisms are implemented to ensure secure attachment, then the attachment precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The elastically displaceable holding elements automatically adjust to engage with the electronic device without requiring precise manual positioning. The elastic displacement allows the holding elements to self-align and secure the device through spring force, eliminating the need for operator precision while maintaining secure attachment.
Solution Approach 2:
The holding elements are designed to be elastically displaceable relative to the base plate, allowing dynamic adjustment during the attachment process. This dynamic capability enables the device to accommodate minor positioning variations while maintaining secure engagement, improving ease of operation without sacrificing attachment precision.
3Ease of operation
If movable holding elements with elastic displacement are used, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The movable holding elements utilize elastic deformation of the base plate material itself to provide the necessary flexibility and movement. Rather than adding complex mechanical linkages, the solution uses the elastic properties of the base plate to enable easy attachment and release operations.
4Reliability
If multiple holding elements are used to secure the device, then the attachment reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The invention allows selection between rigid and movable holding elements based on specific application requirements. This parameter change approach enables optimization of manufacturing cost while maintaining adequate attachment reliability for different electronic devices and mounting scenarios.
