Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive paste is used for mechanical connection, then mechanical connection is achieved, but the connection quality deteriorates due to high temperature affecting the adhesive
Solution Approach 1:
The patent replaces the chemical bonding mechanism of adhesive paste with a mechanical threading system. The connector body and heat sink both feature threaded structures that engage mechanically, eliminating the need for temperature-sensitive adhesive materials while maintaining strong mechanical connection under high temperature conditions.
2Strength
If buckle structure is used for mechanical connection, then mechanical connection is achieved, but maintenance becomes inconvenient due to non-reopenable structure
Solution Approach 1:
The patent transforms the static, permanent buckle connection into a dynamic, reversible threaded connection. The threaded structure allows the connector to be easily screwed onto or off the heat sink, enabling maintenance and replacement operations without permanent attachment, thus improving ease of repair while maintaining connection strength.
3Reliability
If electrical lead or electrical connector is used for electrical connection, then electrical connection is achieved, but the overall connection process becomes complex and costly
Solution Approach 1:
The patent merges electrical connection and mechanical connection into a single integrated component. The connector body simultaneously provides electrical contact through its conductive structure and mechanical attachment through its threaded engagement with the heat sink, eliminating the need for separate electrical leads and simplifying the overall connection process.
Solution Approach 2:
The connector body is designed as a multi-functional component that performs both electrical conduction and mechanical fastening functions. This universal design consolidates multiple connection requirements into a single element, reducing system complexity and cost while maintaining reliable electrical and mechanical connections.
