Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pins are exposed in conventional bi-directional optical modules, then electrical connection is achieved, but pins are easily bent and deformed causing positioning difficulty
Solution Approach 1:
The patent applies nesting by placing the pin inside a metal sleeve, where the pin is contained within the hollow cylindrical structure of the sleeve. This nested configuration protects the pin from external forces that cause bending while maintaining electrical connection functionality, directly resolving the contradiction between pin stability and positioning difficulty
Solution Approach 2:
The metal sleeve acts as an intermediary element between the pin and the external environment. It provides mechanical support and protection to the pin, preventing direct exposure to forces that cause deformation, thereby improving reliability without compromising ease of operation
2Productivity
If pins are exposed in conventional bi-directional optical modules, then installation is simplified, but signal scattering occurs reducing transmission efficiency
Solution Approach 1:
The metal sleeve serves as an intermediary shielding structure that blocks electromagnetic signals from scattering into the surrounding environment. By positioning the sleeve around the pin, it contains the electromagnetic field and prevents harmful signal radiation, thereby improving transmission efficiency
Solution Approach 2:
The metal sleeve creates an electromagnetically inert environment around the pin by acting as a Faraday cage structure. This shields the pin from external electromagnetic interference and prevents the pin from generating harmful electromagnetic radiation, resolving the signal scattering issue
3Reliability
If pins are exposed in conventional bi-directional optical modules, then electrical connection is achieved, but external disturbance is easily introduced
Solution Approach 1:
The metal sleeve acts as a protective intermediary between the pin and external electromagnetic disturbances. It blocks external electromagnetic signals from reaching the pin, thereby maintaining signal stability and reliability by filtering out harmful external interference
