Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex fibre optic splitter module configuration is used to achieve optical connections, then the connection capability is provided, but the device complexity increases and the number of parts increases
Solution Approach 1:
The housing is divided into a first housing part and a second housing part, with the first housing part containing the fixation section and the second housing part containing the accommodating section. This segmentation allows for a simpler overall structure while maintaining connection capability, directly resolving the contradiction between connection capability and device complexity.
2Adaptability or versatility
If a fibre optic splitter module is housed in a module receiving box, then optical connections are achieved, but the capacity for additional connections is limited
Solution Approach 1:
The coupling device is designed as a universal solution that can accommodate multiple optical fibre cables through the accommodating section with multiple passages. The standardized housing design allows it to be used in various configurations without requiring complex module receiving boxes, thereby increasing connection capacity while reducing device complexity.
3Ease of operation
If optical fibre cables are connected using existing coupling devices, then connections are achieved, but the length adjustment of optical fibre cables becomes difficult
Solution Approach 1:
The accommodating section allows for dynamic adjustment of optical fibre cable lengths through its design that accommodates varying cable lengths and provides flexibility in positioning. The passages and spacing can be adjusted to suit different installation requirements, maintaining ease of operation while improving adaptability for length adjustments.
4Adaptability or versatility
If additional connectors are used to facilitate cable adjustment, then the adjustment capability is improved, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The fixation section and accommodating section are merged into a single integrated housing structure, eliminating the need for separate adjustment mechanisms and additional connectors. This integration maintains full adjustment capability while reducing the total number of parts and simplifying assembly, directly resolving the contradiction between adaptability and device complexity.
5Ease of manufacture
If a simplified coupling device design is used, then the number of parts is reduced and assembly is easier, but the reliability of connection may be compromised
Solution Approach 1:
The optical fibre cables are secured in the fixation section before splicing occurs in the accommodating section. This preliminary securing action ensures proper positioning and alignment before the actual connection is made, maintaining connection reliability while allowing for a simplified overall design with fewer parts and easier assembly.
