Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and through holes are used to fix the back plate to the casing, then the connection strength is improved, but the assembly and disassembly process becomes time-consuming and requires auxiliary tools
Solution Approach 1:
The clamping member incorporates a resilient plate that can be elastically deformed during assembly and disassembly. By pulling the resilient plate, the engaging piece moves away from the plate member, enabling tool-free removal. This dynamic mechanism replaces static screw connections with a flexible, reusable clamping system that maintains strength while enabling quick release.
Solution Approach 2:
The clamping member is designed to be manually operated without auxiliary tools. The resilient plate stores elastic energy during assembly and releases it during disassembly, allowing the user to easily remove the plate member by pulling the resilient plate. This self-service mechanism eliminates the need for screwdrivers or other tools, significantly reducing assembly and disassembly time.
2Stability of the object's composition
If through holes are formed in the back plate for screw extension, then the structural integrity is maintained, but the transmission interfaces must be densely disposed to evade the through holes
Solution Approach 1:
The invention removes the through holes from the plate member entirely, replacing them with a clamping member that engages with the edges and surfaces of the plate member. This extraction eliminates the need to route transmission interfaces around hole locations, allowing interfaces to be positioned optimally without structural compromises.
Solution Approach 2:
The clamping member is divided into distinct functional components: the resilient plate for elastic deformation, the engaging piece for securing the plate member, and the abutment arm for electrical connection. This segmentation allows each component to perform its specific function independently, maintaining structural integrity while simplifying the overall interface layout.
3Ease of operation
If the clamping member uses a resilient plate with engaging piece, then tool-free assembly and disassembly is achieved, but the connection strength may be reduced compared to screw fixation
Solution Approach 1:
The resilient plate provides dynamic clamping force that adapts to the plate member's position and orientation. The elastic deformation allows the engaging piece to maintain constant pressure on the plate member, ensuring strong connection during operation while enabling easy release when force is applied to the resilient plate.
Solution Approach 2:
The abutment arm features a curved abutment face that conforms to the metal pad surface, maximizing contact area and distributing clamping force evenly. This curved geometry enhances both the connection strength and the electrical contact area, ensuring reliable mechanical and electrical connections simultaneously.

AI summary
A casing for fixing a plate member includes a casing body having opposite first and second side plates, and a clamping member having a resilient plate disposed on an inner side of the second side plate, at least one abutment arm protruding inwardly from the resilient plate and adapted to abut against a first surface of the plate member, and an engaging piece proximate to the abutment arm and adapted to releasably engage a second surface of the plate member. The first side plate and the resilient plate are respectively adapted to abut against first and second ends of the plate member for clamping therebetween the plate member. The resilient plate is pullable to move the engaging piece away from the second surface of the plate member.
