Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If optical fiber is used for short-distance transmission, then transmission capacity is improved, but noise-related problems occur making high-quality high-speed signal transmission difficult
Solution Approach 1:
The optical transmission medium is divided into multiple independent optical transmission regions (first, second, third, and fourth regions) arranged in parallel within a single sheet. Each region can transmit optical signals independently, allowing high-capacity transmission while isolating noise effects to specific regions, thereby maintaining signal quality.
Solution Approach 2:
A light-guiding sheet serves as an intermediary structure that guides and transmits optical signals from the light emitting element to the light receiving element. This intermediary structure enables high-capacity transmission while managing noise through its integrated design with multiple optical transmission regions.
2Strength
If tape core wire with resin tape layer and integrally coated layer is used, then optical fiber protection is improved, but connector installation becomes complicated requiring peeling and individual fiber insertion
Solution Approach 1:
Multiple optical fibers are merged into a single integrally molded sheet structure where the core regions, clad regions, and coating regions are integrated together. This unified structure eliminates the need for separate handling of individual fibers during connector installation, allowing the entire sheet to be inserted as one unit while maintaining protective functionality.
Solution Approach 2:
The optical fibers are pre-arranged and integrally molded into a structured sheet with protective coating before connector installation. This preliminary structuring eliminates the need for peeling and individual fiber manipulation during installation, as the pre-formed sheet can be directly inserted into the connector.
3Reliability
If multiple optical fibers are connected individually to MT connector, then connection reliability is improved, but work time increases significantly
Solution Approach 1:
Multiple optical transmission regions are combined into a single integrally molded sheet that can be inserted into the MT connector as one unit. This merging approach maintains connection reliability by ensuring proper alignment of all optical regions while dramatically reducing installation time compared to individual fiber insertion.
Solution Approach 2:
The integrally molded sheet serves as a universal connection interface that can be directly inserted into the MT connector, replacing the need for individual fiber connections. This multi-functional structure maintains reliability while simplifying the installation process for multiple fibers simultaneously.
