Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an optical isolator and multiple glass sheets are used to ensure optical signal transmission, then the reliability of signal transmission is improved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent merges the optical isolator function and lens focusing function into a single integrated light-transmitting body. The light-transmitting body contains both the optical isolation capability and the lens array structure, eliminating the need for separate optical isolator components and multiple glass sheets. This integration directly reduces device complexity while maintaining signal transmission reliability through the unified design.
2Reliability
If multiple independent components (optical isolator, glass sheets, lenses) are used to achieve optical signal transmission, then the optical signal transmission function is ensured, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent combines multiple independent components (optical isolator, glass sheets, lenses) into a single integrated light-transmitting body that can be molded as one piece. This integration eliminates the need for separate manufacturing and assembly of multiple components, significantly improving manufacturing ease while ensuring optical signal transmission functionality through the unified structure.
Solution Approach 2:
The light-transmitting body serves multiple functions simultaneously: it acts as the optical isolator, contains the lens array for signal focusing, provides structural support, and enables signal transmission. This multi-functionality reduces the number of separate components needed, thereby simplifying manufacturing processes and reducing costs while maintaining transmission reliability.
3Reliability
If a complex assembly process with multiple couplings is used to assemble optical components, then the optical signal transmission is achieved, but the production time and assembly complexity increase
Solution Approach 1:
The patent integrates multiple optical components into a single light-transmitting body that can be assembled as one unit. This eliminates the need for multiple separate coupling operations (coupling optical isolator to glass sheets, then to lenses, then to PCB), significantly improving assembly efficiency while maintaining the optical communication function through the integrated design.
4Stability of the object's composition
If two pieces of processed glass are used to press and fix multiple optical fibers, then the optical fibers are securely fixed, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent integrates the optical fiber fixation function into the light-transmitting body itself. The light-transmitting body is designed with built-in structures (such as positioning holes or integrated clamping features) that directly secure the optical fibers, eliminating the need for separate glass sheets and glue-based fixation processes. This integration maintains fiber fixation stability while simplifying the manufacturing process.
