Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based fastening method is used to secure the circuit board, then the assembly is strong and reliable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a snap-engaging mechanism. The circuit board features snap-engaging elements that automatically engage with corresponding structures on the support, eliminating the need for screws and simplifying the assembly process while maintaining secure attachment.
Solution Approach 2:
The snap-engaging elements are designed to automatically engage and secure the circuit board to the support without requiring additional fastening operations. The resilient nature of the circuit board allows the snap-engaging elements to self-lock into place, making the assembly process self-completing and eliminating the need for separate fastening steps.
2Ease of manufacture
If adhesive method is used to secure the circuit board, then the assembly process is simplified, but the signal stability is compromised due to space constraints
Solution Approach 1:
The patent replaces adhesive bonding with a mechanical snap-engaging system. This mechanical approach provides reliable signal stability by ensuring proper spacing and positioning of the circuit board, while still maintaining ease of assembly through the simple snap-in mechanism that does not require complex bonding processes.
3Reliability
If traditional fastening methods are used, then the circuit board is securely fixed, but additional space is required for fasteners increasing device size
Solution Approach 1:
The patent merges the circuit board structure with the fastening mechanism by integrating snap-engaging elements directly into the circuit board. This eliminates the need for separate fasteners and reduces the overall space required for securing the circuit board, as the fastening function is combined with the board structure itself.
Solution Approach 2:
The patent extracts and eliminates the need for separate fasteners (screws, clips, etc.) by incorporating the fastening function directly into the circuit board through snap-engaging elements. This removal of additional components reduces the assembly space and simplifies the overall structure.
4Manufacturing precision
If more assembly components are used to secure the circuit board, then the positioning accuracy is improved, but the device complexity increases
Solution Approach 1:
The snap-engaging elements serve multiple functions simultaneously: they provide secure mechanical attachment, ensure accurate positioning of the circuit board, and maintain proper spacing for signal stability. This multi-functionality eliminates the need for separate positioning components and fasteners, reducing overall assembly complexity.
