Automotive Slide Member Lubrication for Static Discharge Without Staining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive lubricants used in automobiles to eliminate static electricity often adhere to operators and other components, causing decreased workability and designability due to their black color, which affects handling stability and aesthetics.
Innovation Solution
An automotive slide member with a first lubricant containing minimal or no conductive carbon applied to touchable areas and a second lubricant with a higher conductive carbon content applied to non-touchable areas, improving static elimination and handling stability while minimizing adhesion and maintaining design aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lubricant containing conductive carbon is applied to eliminate static electricity, then static elimination performance is improved, but the lubricant adheres to operators and components causing decreased workability and designability
Solution Approach 1:
The slide member is divided into multiple regions with different lubricant applications: a first region (touchable parts) receives lubricant with low or no conductive carbon content, while a second region (non-touchable parts) receives lubricant with high conductive carbon content. This segmentation allows each region to be optimized for its specific function without compromising the other.
Solution Approach 2:
Different regions of the slide member are given different lubricant properties tailored to their specific requirements. Touchable regions have lubricant with minimal carbon content for non-staining properties, while non-touchable regions have lubricant with high carbon content for optimal static elimination, creating local quality variations that solve the contradiction.

If conductive carbon is added to lubricant for static elimination, then electrical conductivity is improved, but the lubricant becomes black and adheres to surfaces

This segmentation allows each region to be optimized for its specific function without compromising the other.

AI summary
Automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.
