Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a possibility of metal abrasion powder generation on sliding surfaces when components that slide between metals undergo repeated rotational operations in endoscope devices.
Innovation Solution
An endoscope imaging device with an attachment portion that includes a first metal portion with a first sliding surface and a second metal portion with a second sliding surface, where a resin portion is configured on at least one of the sliding surfaces to reduce abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal components slide against each other during rotational operations, then the structural strength and durability are maintained, but metal abrasion powder is generated on the sliding surfaces
Solution Approach 1:
A resin portion is introduced as an intermediary material between the first metal sliding surface and the second metal sliding surface. This resin layer prevents direct metal-to-metal contact during rotational operations, thereby eliminating metal abrasion powder generation while maintaining the structural strength of the original metal components.
Solution Approach 2:
The patent creates a composite sliding interface by combining metal components with a resin material. The resin portion is formed on at least one of the metal sliding surfaces, creating a metal-resin composite structure that combines the strength of metal with the low-friction, non-abrasive properties of resin.
2Duration of action of moving object
If metal components undergo repeated rotational operations, then the operational functionality is maintained, but abrasion occurs between sliding components
Solution Approach 1:
The resin portion serves as a mediator that protects the metal sliding surfaces from direct contact and wear during repeated rotational operations. This intermediary layer significantly improves abrasion resistance while allowing the operational functionality to continue indefinitely.
Solution Approach 2:
The patent changes the surface material parameter from pure metal to metal-with-resin-coating. This parameter change transforms the friction and wear characteristics of the sliding surface, reducing coefficient of friction and preventing material transfer that would otherwise occur during repeated rotation.
