Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical modules are designed with standardized form factors to promote compatibility, then product compatibility is improved, but the ability to prevent incorrect port insertion is worsened
Solution Approach 1:
The patent applies local quality by providing different visual features (such as different colors, patterns, or markings) on the exposed parts of different optical modules. This allows each optical module to have unique identification characteristics while maintaining the same standardized form factor, thereby preventing incorrect port insertion without compromising compatibility.
Solution Approach 2:
The patent employs asymmetry by introducing non-symmetric visual features on the exposed parts of optical modules. Different optical modules have different visual characteristics (e.g., different colored labels, patterns, or shapes) that create asymmetric identification, making it impossible to incorrectly insert modules into mismatched ports while preserving standardized interfaces.
2Ease of operation
If optical modules are designed with standardized form factors to reduce maintenance burden, then ease of operation is improved, but the risk of incorrect port insertion increases
Solution Approach 1:
The patent utilizes color changes by implementing different colors or color patterns on the exposed parts of different optical modules. This visual differentiation allows operators to quickly identify and correctly connect optical modules during maintenance operations, reducing the maintenance burden while simultaneously preventing incorrect port insertion through intuitive visual cues.
3Reliability
If visual features are added to exposed parts to prevent incorrect insertion, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the optical module into distinct components with different visual features on the exposed parts. Each optical module is segmented with unique identification markings on its exposed portion, allowing for easy differentiation without requiring complex overall system changes. This localized segmentation approach improves reliability while minimizing the increase in device complexity.
