Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If spot welding is used to fix the positioning member on the circuit board, then the manufacturing process is simple, but the connection stability is poor and the positioning member is easily separated under shearing force
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical joining) with a mechanical clamping system. The connecting clip uses elastic deformation of its clamping sheets to generate clamping force that secures the positioning member to the circuit board without welding, thereby improving connection stability while maintaining manufacturing simplicity.
Solution Approach 2:
The connecting clip is designed with elastic clamping sheets that can dynamically adapt to the positioning member. The clamping sheets are curved and elastically deformable, allowing the connection to withstand shearing forces while maintaining stable contact through elastic recovery.
2Ease of operation
If the positioning member is secured by welding, then the assembly process is straightforward, but the connection cannot effectively resist shearing force when cables are pulled
Solution Approach 1:
The connecting clip is pre-formed with curved clamping sheets that are elastically deformed during assembly to generate clamping force. This preliminary elastic deformation creates a strong mechanical grip on the positioning member before any shearing forces are applied, ensuring the connection can withstand cable pulling forces.
3Device complexity
If conventional welding methods are used, then the structure is simple, but the high-frequency transmission performance is not enhanced
Solution Approach 1:
The connecting clip serves multiple functions: it mechanically secures the positioning member to the circuit board through clamping, provides electrical connection for signal transmission through its conductive structure, and enhances high-frequency transmission performance through its shielding structure. This multi-functionality replaces the need for separate welding and shielding components.
