Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of subunits is increased to accommodate more components, then the number of mounted components increases, but the wiring structure becomes complicated and wiring connecting work becomes difficult
Solution Approach 1:
The patent merges multiple subunits into a single integrated housing unit. All optical components and electric components are mounted on opposite sides of the same housing, eliminating the need for interconnections between multiple subunits. This reduces wiring complexity while maintaining the capability to mount numerous components.
Solution Approach 2:
The patent utilizes the third dimension by mounting components on both the front and back sides of the housing. This bidirectional mounting approach doubles the component capacity without increasing the number of housing units or complicating wiring, as components on opposite sides do not require interconnections.
2Quantity of substance
If the number of subunits is increased to accommodate more components, then the number of mounted components increases, but the space occupied by interconnections increases
Solution Approach 1:
By combining all components into a single housing unit, the patent eliminates interconnection cables between subunits entirely. This removes the volume occupied by interconnections, allowing more space for mounting additional components within the same overall footprint.
3Quantity of substance
If the number of mounted components increases, then communication traffic capacity increases, but heat dissipation becomes difficult
Solution Approach 1:
The patent utilizes both sides of the housing for component mounting, effectively doubling the surface area available for heat dissipation. This bidirectional layout allows heat to be dissipated from multiple surfaces simultaneously, improving thermal management capability while accommodating more components.
4Adaptability or versatility
If the number of mounted components increases, then signal control capability improves, but it becomes difficult to secure heat dissipation
Solution Approach 1:
The patent combines optical components and electric components in a single housing with heat dissipation structures designed to handle thermal loads from all components. This integrated approach ensures that as component count and control capability increase, the heat dissipation system scales accordingly within the same thermal envelope.
