Composite Low-Friction Gib for Cleanroom Linear Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing processes, particularly in clean room environments, face challenges with lubricant contamination, migration, and operational deficiencies in injection molding, leading to aesthetic and functional rejects, increased maintenance costs, and the need for frequent reapplication of lubricants.
Innovation Solution
A low friction gib comprising a metallic substrate with a fabric resin composite attachment that eliminates the need for lubricants by providing a low friction contact surface, allowing for axial or linear motion without lubrication, and is secured using mechanical fasteners or adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If applied lubricants are used in gibs or ways, then friction is reduced, but contamination occurs in the production environment
Solution Approach 1:
The patent removes lubricants from the system entirely by using a self-lubricating polymer material in the gib, eliminating the source of contamination while maintaining friction reduction
Solution Approach 2:
The patent replaces the mechanical lubrication system (applied lubricants) with a material-based solution (self-lubricating polymer) that provides lubrication through its inherent properties rather than external application
2Force
If lubricants are applied to motionable components, then friction is reduced, but lubricant migration occurs to production parts
Solution Approach 1:
The patent eliminates lubricants from the system by using a self-lubricating polymer material, removing the source of migration while maintaining friction reduction
Solution Approach 2:
The gib material provides its own lubrication through the self-lubricating properties of the polymer, eliminating the need for external lubricants that could migrate
3Force
If applied lubricants are used, then friction is reduced, but service life is limited and reapplication is required
Solution Approach 1:
The self-lubricating polymer provides continuous lubrication without requiring external reapplication, extending service life through self-sustaining friction reduction
Solution Approach 2:
The polymer material maintains continuous lubrication throughout its service life without interruption or reapplication, ensuring consistent friction reduction
4Force
If lubricants are applied in clean room environments, then friction is reduced, but aesthetic and functional rejects occur
Solution Approach 1:
The patent removes lubricants from the system by using a self-lubricating polymer, eliminating contamination that causes aesthetic and functional defects
Solution Approach 2:
The patent replaces external lubrication with an inherent material property (self-lubricating polymer), preventing contamination of molded parts
