Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables in the market generate heat during power transmission due to multiple layers, leading to increased internal heat and reduced service life.
Innovation Solution
A photoelectric composite flexible high-voltage reel cable design featuring a polyethylene outer sheath, double-face plastic-coated steel belt, insulating tape, anti-crack protective sleeve, power cord body, filler rope, reinforcement, and optical fiber body, with a metal radiating column and movable grooves to dissipate heat and prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple layers and cores are added to the cable to improve buffering and bearing capacity, then the cable's mechanical strength and protection are improved, but the internal heat accumulation increases and service life is reduced
Solution Approach 1:
The patent extracts the heat dissipation function from the traditional multi-layer cable structure by introducing a dedicated heat dissipation column that penetrates through the outer sheath. This separate heat dissipation pathway removes the harmful heat accumulation effect while preserving the protective function of the outer layers, thereby extending cable service life without compromising mechanical strength
Solution Approach 2:
The heat dissipation column is nested within the existing cable structure, penetrating through the outer sheath and extending into the cable core. This nested design allows the heat dissipation function to be integrated within the existing multi-layer structure, enabling simultaneous achievement of mechanical protection and thermal management
2Reliability
If multiple protective layers are added to the cable, then the cable's buffering and protection performance are improved, but the heating speed decreases and cumulative heat increases
Solution Approach 1:
The heat dissipation column acts as an intermediary element that facilitates heat transfer from the cable core through the outer sheath to the surrounding environment. This intermediary structure provides a dedicated thermal pathway that bypasses the insulating effect of the protective layers, enabling effective heat dissipation while maintaining the integrity of the protective layer structure
