Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal contact-connection (soldering or welding) is used, then reliable electrical connection is achieved, but accessibility is required for weld or soldering connections which increases installation space requirements
Solution Approach 1:
The patent extracts the connection process from requiring external accessibility by performing the electrical connection directly on the printed circuit board surface. The clamping connector establishes contact through the cutout without needing access to solder joints or welding areas, eliminating the space required for thermal connection processes while maintaining connection reliability through direct mechanical and electrical contact.
2Ease of manufacture
If cold contact-connection technique is used, then no thermal connection is required, but relatively accurate positioning of the joining partner is required which makes the assembly process complex
Solution Approach 1:
The clamping connector incorporates flexible contact elements that can dynamically adapt to positioning variations. These elastic contacts deform to accommodate misalignments between the joining partner and the connector, maintaining reliable electrical connection without requiring high positioning precision. This dynamic flexibility eliminates the need for complex positioning mechanisms while preserving assembly simplicity.
3Reliability
If complex contact-connection methods are used, then reliable electrical connection is achieved, but complex tools are needed which increases device complexity
Solution Approach 1:
The clamping connector performs the electrical connection function through its own structural design without requiring external complex tools. The flexible contact elements automatically establish and maintain electrical contact when the joining partner is inserted through the cutout, eliminating the need for soldering irons, welding equipment, or other complex connection tools while ensuring reliable electrical connection.
