Linear Guideway End Cap Resilient Sheet Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear guideway end cap modules lack effective positioning and support for oil-absorbing sheets, leading to inefficiencies and higher costs due to the inclusion of metallic sheets.
Innovation Solution
The linear guideway features an end cap module with a U-shaped main plate, surrounding plate, and U-shaped resilient sheets that provide improved positioning and support without metallic sheets, enhancing the positioning effect and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic sheets are used in the end cap module to support oil-absorbing sheets, then the structural strength is improved, but the manufacturing cost increases and the positioning effect deteriorates
Solution Approach 1:
The patent replaces expensive metallic sheets with inexpensive resin material sheets that can be easily manufactured and disposed of. The resin sheets are designed to be replaced periodically, providing a cost-effective solution that eliminates the need for durable metallic components while maintaining functional requirements.
Solution Approach 2:
The patent changes the material parameter from metal to resin, fundamentally altering the properties of the support sheets. This material substitution reduces cost, improves positioning effectiveness through better compliance, and maintains sufficient structural strength for the application requirements.
2Strength
If metallic sheets are used in the end cap module, then the structural support is improved, but the positioning effect between oil-absorbing sheets and end cap deteriorates
Solution Approach 1:
The patent changes the material parameter from metal to resin, which provides better compliance and conformability. This enables the support sheets to better adapt to the oil-absorbing sheets and end cap surfaces, significantly improving the positioning effect through enhanced contact and alignment.
Solution Approach 2:
The patent employs thin resin sheets that exhibit flexible characteristics, allowing them to conform to the contours of the end cap and oil-absorbing sheets. This flexibility enhances the positioning effect by ensuring intimate contact and precise alignment, which rigid metallic sheets cannot achieve.
3Ease of manufacture
If resin material sheets are used instead of metallic sheets, then the manufacturing cost is reduced and positioning effect is improved, but the structural strength may be compromised
Solution Approach 1:
The patent accepts the trade-off of using less durable but much cheaper resin sheets as disposable components. The structural strength required is sufficient for the intended service life of these replaceable sheets, making the cost reduction worthwhile while meeting the strength requirements for normal operation.

AI summary
A linear guideway includes an end cap and a resilient sheet. The end cap includes a main plate, a surrounding plate, and two side positioning pillars. The surrounding plate and the side positioning pillars are perpendicularly extended from the main plate. The inner edge of the main plate has two protruding segments facing with each other. The side positioning pillars are respectively arranged adjacent to the first protruding segments. The resilient sheet has two first side positioning holes respectively sleeving the two first side positioning pillars, and the resilient sheet is disposed on the main plate. Thus, by the cooperation of the first side positioning pillar and the first side positioning hole, the resilient sheet is firmly received in the end cap and the first side positioning pillars support the inner edge of the resilient sheet.
