Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active cable connectors in communication networks generate heat during signal conversion and processing, which can lead to component failure and leakage of excess heat affecting surrounding components, reducing their lifespan and functionality.
Innovation Solution
A thermal management system for active cable connectors is introduced, featuring a shell with multiple heat-transfer areas and a back plate that absorbs and dissipates thermal energy from heat-generating components, utilizing thermal pads to transfer heat from PCBs to the shell and back plate, and then dissipating it to the environment through the shell's external surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heat-generating components are used for signal conversion and processing, then data transmission functionality is improved, but heat accumulates causing component failure and reducing reliability
Solution Approach 1:
The patent extracts heat away from heat-generating components by introducing a dedicated thermal management system comprising a shell with heat-transfer areas and a back plate with thermal pads. This separates the heat dissipation function from the signal processing function, allowing components to operate reliably while maintaining data transmission functionality.
Solution Approach 2:
The patent introduces thermal pads and a back plate as intermediary elements between heat-generating components and the external environment. These intermediaries facilitate heat transfer from components to the shell and ultimately to ambient air, preventing direct heat accumulation at component locations while preserving component functionality.
2Productivity
If heat-generating components are used for signal conversion, then conversion capability is improved, but excess heat leaks to surrounding components causing damage and reducing their lifespan
Solution Approach 1:
The patent extracts excess heat from the system at its source by positioning the back plate and thermal pads in direct contact with heat-generating components. This prevents heat from propagating to surrounding components by removing it through dedicated heat-transfer pathways to the shell and ambient environment.
Solution Approach 2:
The patent converts harmful heat into a manageable thermal flow by designing controlled heat-transfer pathways through thermal pads, back plate, and shell structures with heat-transfer areas. This transforms uncontrolled heat leakage that damages components into a directed thermal management process that protects surrounding components while maintaining conversion capability.
3Duration of action of stationary object
If thermal management structures are added to absorb and dissipate heat, then component lifespan is extended, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the shell to serve both as the structural enclosure for the connector and as a heat-dissipating component with integrated heat-transfer areas. The back plate simultaneously provides mechanical support and thermal conduction pathways. This reduces the need for separate dedicated cooling components, extending lifespan while minimizing added complexity.
Solution Approach 2:
The patent merges the thermal management function with existing structural components. The back plate combines mechanical support and heat conduction functions, while the shell integrates enclosure and heat dissipation functions through heat-transfer areas. This consolidation extends component lifespan without proportionally increasing device complexity.
