Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws, adhesive strips, or fasteners are used to mount the circuit board onto the backplate, then the circuit board can be securely fixed, but the assembly and disassembly steps become cumbersome and production efficiency is reduced
Solution Approach 1:
The mounting member integrates multiple functions into a single component: it provides structural support for the circuit board, electrical connection through contact pads, and mechanical fixation through the concave-convex snap-fit mechanism with the backplate. This eliminates the need for separate screws, adhesive strips, or fasteners, thereby simplifying assembly and improving production efficiency while maintaining secure fixation.
Solution Approach 2:
The patent replaces traditional mechanical fastening systems (screws, fasteners) and chemical bonding (adhesive strips) with a snap-fit mechanism based on elastic deformation. The concave portion on the backplate and the corresponding convex structure on the mounting member create a secure connection through elastic recovery, enabling tool-free assembly and disassembly while maintaining reliable fixation.
2Ease of manufacture
If traditional mounting methods (screws, adhesive strips, fasteners) are used, then the circuit board can be mounted onto the backplate, but additional fixing pieces are required increasing device complexity
Solution Approach 1:
The mounting member consolidates multiple separate components (circuit board support structure, electrical connection elements, and mechanical fixation features) into a single integrated component. The concave-convex snap-fit mechanism is built directly into the mounting member and backplate, eliminating the need for separate fixing pieces and reducing overall device complexity.
Solution Approach 2:
The fixation function is extracted from separate auxiliary components (screws, fasteners, adhesive strips) and integrated directly into the mounting member and backplate structure. The concave portion on the backplate and the matching convex feature on the mounting member provide the fixation mechanism as an inherent part of the assembly, removing the need for additional fixing pieces.
3Reliability
If additional fixing pieces are used to secure the mounting member, then secure attachment is achieved, but assembly and disassembly steps become more complex
Solution Approach 1:
The patent replaces complex multi-step mechanical fastening procedures (screw tightening, fastener installation, adhesive application) with a simple snap-fit mechanism. The elastic deformation-based connection allows the mounting member to be securely attached by simply pressing it onto the concave portion of the backplate, and equally easily removed by applying reverse force, thereby maintaining reliability while dramatically improving ease of operation.
