Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional optical engine assembly methods are used, then assembly complexity is high and optical coupling efficiency is low, but the patent achieves high optical coupling efficiency through optimized fiber positioning and lens coupling structures
Solution Approach 1:
The optical engine is divided into modular components: fiber joint module with positioning through holes, lens set module with multiple lenses, and photoelectric module. Each module can be assembled and adjusted independently, reducing overall assembly complexity while maintaining high optical coupling efficiency through precise modular positioning.
Solution Approach 2:
The fiber joint includes pre-formed positioning through holes that guide fiber placement before final assembly. The lens set is pre-configured with multiple lenses at specific positions to optimize optical paths. These preliminary preparations ensure high optical coupling efficiency without requiring complex real-time adjustment during assembly.
2Loss of energy
If conventional optical path designs are used, then optical path length is long causing signal loss, but the patent reduces optical path length through optimized lens positioning and fiber coupling
Solution Approach 1:
The patent employs multiple lenses arranged in specific spatial dimensions to optimize the optical path. The lens set includes first lenses and second lenses positioned at different locations and orientations, creating efficient light paths through three-dimensional space reduction rather than simply shortening the linear distance.
Solution Approach 2:
The lens set acts as an intermediary between the fiber joint and photoelectric module, optimizing the optical path through controlled refraction and focusing. The multiple lenses in the set work together to minimize optical path length while maintaining signal integrity, reducing energy loss in the transmission process.
3Manufacturing precision
If simple fiber coupling without guiding structures is used, then assembly is easier but fiber alignment precision is insufficient, but the patent uses fiber guiding grooves to improve alignment while maintaining ease of assembly
Solution Approach 1:
The fiber joint includes integrated fiber guiding grooves that automatically guide fiber placement during assembly. These grooves are formed as part of the fiber joint structure itself, providing self-alignment functionality that improves fiber positioning precision without requiring separate complex alignment tools or procedures, thus maintaining ease of assembly.
