Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots face challenges in protecting power lines from wear and friction during relative motion between rotatable components, requiring a solution that minimizes friction and wear while allowing for a wide range of motion.
Innovation Solution
A conducting line protection device comprising a basic ring section, a hollow cylinder section, an inner edge rounding section, and a radial bearing section for rotatable support, which can be constructed in single pieces or assembled, using a radial bearing section that reduces friction and wear by allowing power lines to be routed through it, either as individual lines or cable bundles, and can be pre-installed or retrofitted onto industrial robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power lines are routed through a rotatable joint without protection, then the range of motion is maintained, but wear and friction on the power lines increases
Solution Approach 1:
A conducting line protection device is introduced as an intermediary component between the power lines and the rotatable joint. This protective device includes a radial bearing section that supports the power lines during rotation, preventing direct contact and friction between the cables and the joint mechanism, thereby reducing wear while maintaining full range of motion
2Reliability
If a radial bearing section is added to support the conducting line protection device, then wear and friction on power lines are reduced, but device complexity increases
Solution Approach 1:
The radial bearing section is integrated into the conducting line protection device as a unified component rather than a separate assembly. The bearing section is directly formed as part of the protection device's ring structure, combining the protective function with the bearing function in a single integrated component, thus reducing overall complexity while maintaining wear reduction benefits

Function Achieved in This Case
The solution effectively reduces wear and friction on power lines, enabling smooth and low-friction movement of the carousel relative to the base frame, with the option of using rolling-contact bearings for enhanced support, ensuring problem-free operation and longer component lifespan.
Implementation Method 1
wear to the at least one power line can be reduced, and the motion of the carousel relative to the base frame may involve less friction
