Cable Wire Gaps as Air Purge Passages in Robot Electrical Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purge mechanisms for robots are inefficient in preventing external air, particularly moisture and flammable gases, from entering electrical components, leading to potential short circuits and rust, and often require additional tubes that increase space and manufacturing costs.
Innovation Solution
An air purge mechanism using cables with bundled wires and insulating sheaths, where gaps between the wires act as air passages, connecting multiple containers within the robot, and a tube joint for compressed air supply, eliminating the need for separate tubes and enhancing flexibility and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tubes are used to supply compressed air to electrical components, then air purge functionality is achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the air supply function with the existing cable structure by forming air passages through gaps between bundled wires within the cable sheath. This eliminates the need for separate air supply tubes and integrates multiple functions (electrical connection and air purge) into a single component, thereby reducing device complexity while maintaining protection reliability
2Reliability
If separate tubes are used for air supply, then air purge functionality is achieved, but space requirements and manufacturing costs increase
Solution Approach 1:
The air supply passages are integrated within the cable structure by utilizing gaps between bundled wires. This eliminates the need for separate air supply tubes and external air supply devices, thereby reducing space occupation while maintaining the reliability of preventing short circuits and rust through effective air purge functionality
3Reliability
If conventional sealed containers are used, then protection against external air is achieved, but flexibility and ease of installation are reduced
Solution Approach 1:
The patent integrates air purge functionality directly into the cable structure by forming air passages through gaps between bundled wires within the sheath. This eliminates the need for separate air supply tubes and complex installation procedures, thereby improving flexibility and ease of installation while maintaining protection against external air through effective air purge capability
