Seamless Roller Rings for Linear Motion Friction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding-assistant units for linear motion apparatuses have complex components and assembly issues, leading to increased friction due to seam formation between assembled parts, making manufacturing and operation difficult.
Innovation Solution
The design features elongated rectangular roller rings that are assembled as a single unity without seams, with simplified components and a gap for easier assembly, ensuring smooth contact between rollers and the roller rings, reducing friction and enhancing ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sliding-assistant units use multiple assembled components, then the structure can provide sliding assistance, but the components become complicated and assembly becomes difficult
Solution Approach 1:
The patent merges multiple separate components (U-shaped roller ring, rollers, keeping members, and track engagement members) into a single integrated sliding-assistant unit. This unity structure eliminates the complexity of assembling multiple different components while maintaining all necessary functions for sliding assistance.
2Ease of manufacture
If U-shaped roller rings are assembled from two half shells, then the structure can be manufactured, but seams are formed causing non-smooth inner surfaces
Solution Approach 1:
The patent designs the U-shaped roller ring as a single integrated component rather than assembling two half shells. This eliminates the seam that would form between joined parts, ensuring a smooth inner surface that reduces friction with the rollers while maintaining manufacturability through single-piece fabrication.
3Ease of manufacture
If roller rings have seams from assembled halves, then the structure can be constructed, but friction between roller ring and rollers increases
Solution Approach 1:
The patent creates a seamless U-shaped roller ring through single-piece construction, eliminating the seam that would create surface irregularities. This smooth inner surface directly reduces friction between the roller ring and rollers, improving operational efficiency while remaining manufacturable.
4Reliability
If sliding-assistant units have complex components, then the structure can provide comprehensive function, but manufacturing and assembling become difficult
Solution Approach 1:
The patent integrates multiple functional components into a single unified sliding-assistant unit structure. This merger maintains all necessary functions (roller support, track engagement, positioning) while dramatically simplifying manufacturing and assembly processes by eliminating the need to assemble multiple separate components.

AI summary
A linear motion apparatus has a linear track, a slider and two sliding-assistant units for a linear motion apparatus. The sliding-assistant units for a linear motion apparatus is mounted between the track and the slider to enhance ease of movement between the track and the slider, and each sliding-assistant unit has two roller rings to receive rollers. The roller rings are elongated rectangular rings, are selectively mounted oppositely crossly around each other. Each roller ring is designed with reduced components to make manufacturing and assembling the sliding-assistant unit easier. Moreover, the roller ring is designed as one unity so no seam will be formed due to assembling two different pieces, such that ensures contact between the rollers and the roller ring smooth.
