Knitted Spacer Cover for Robot Paint Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot covers for painting processes are inadequate in effectively absorbing paint overspray, leading to paint dripping and potential defects in the painting process.
Innovation Solution
A cover member for robots comprising an inner and outer knitted fabric layer with spacer yarns, allowing for stretchability, compressibility, and paint absorption, which is secured to the robot to absorb paint overspray and prevent dripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional robot covers are used, then the robot is protected from paint overspray, but paint dripping occurs and paint absorption is insufficient
Solution Approach 1:
The cover member is constructed as a composite material system consisting of an inner knitted fabric layer, an outer knitted fabric layer, and spacer yarns positioned between them. This composite structure combines the protective function of fabric layers with the absorptive function of the spacer yarns, enabling simultaneous paint absorption and drip prevention while maintaining robot protection
Solution Approach 2:
The spacer yarns create a porous, three-dimensional structure between the inner and outer fabric layers that provides high surface area and void space for paint absorption. This porous configuration allows the cover to effectively absorb paint overspray while preventing it from reaching the robot surface and causing drips
2Reliability
If foam materials are used for paint absorption, then paint dripping is reduced, but the material lacks stretchability and conformability to robot surfaces
Solution Approach 1:
The cover member utilizes flexible knitted fabric layers that can stretch and conform to the complex surfaces of robot arms and components. The knitted structure provides inherent elasticity and flexibility, allowing the cover to adapt to various robot geometries while maintaining its paint absorption function through the integrated spacer yarns
Solution Approach 2:
By combining flexible knitted fabrics with absorptive spacer yarns in a composite structure, the invention achieves both the stretchability needed to conform to robot surfaces and the paint absorption capability previously only available in foam materials

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cover member effectively reduces paint dripping and protects the robot from overspray, maintaining a high-quality paint finish by absorbing paint into the space between the inner and outer knitted substructures.
Implementation Method 1
a cover member for a robot having stretchability, compressibility and resiliency similar to conventional resilient foam materials while at the same time providing characteristic for absorbing paint to substantially reduce paint dripping
