Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide systems face challenges in easy assembly and subsequent adjustment of tolerance-induced guidance play between movable guide portions, requiring complex solutions that are not efficiently addressed.
Innovation Solution
A sliding element with rotatable portions and a contact surface of axial inclination, allowing variable axial structural height adjustment through relative rotation and a releasable arresting mechanism, utilizing plastic materials for low-maintenance lubricant-free sliding and simple fixing, with adjustable angular positions and a tool-activated unlocking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide systems use fixed structural height components, then assembly is simple, but tolerance-induced guidance play cannot be corrected
Solution Approach 1:
The sliding element incorporates a rotatable second portion that allows dynamic adjustment of the axial overall structural height. The releasable arresting means enables the system to transition between fixed and adjustable states, allowing correction of tolerance-induced guidance play while maintaining operational stability.
Solution Approach 2:
The invention changes the parameter of axial overall structural height from fixed to variable through rotation of the second portion about the axis of rotation. This allows continuous adjustment of the height parameter to compensate for tolerance variations and correct guidance play in the guide system.
2Manufacturing precision
If guide systems allow adjustment of guidance play, then precision is improved, but assembly and adjustment complexity increases
Solution Approach 1:
The sliding element is divided into a first portion and a second portion that can rotate relative to each other. This segmentation allows independent adjustment of the second portion to correct guidance play without affecting the overall assembly process or requiring complex adjustment mechanisms.
Solution Approach 2:
The releasable arresting means is designed to be actuated from the exterior of the guide system, allowing users to adjust and lock the angular position of the second portion without disassembly or complex tools. The mechanism serves itself by maintaining the adjusted position automatically once set.
3Ease of repair
If sliding surfaces use plastic materials, then maintenance is reduced, but load-bearing capacity may be limited
Solution Approach 1:
The sliding element uses plastic materials for the sliding surfaces of both the first and second portions, creating a composite system that combines the advantages of plastic (low maintenance, lubricant-free operation) with the design flexibility needed to achieve adequate load-bearing capacity through the adjustable height mechanism.

AI summary
A sliding element works with a guide system having two guide parts that can be moved relative to one another. The sliding element can be fixed to one of the guide parts by an attachment face (3) and includes, on a face opposite the attachment face (3), a sliding surface (6) so as to be slidingly supported on the other guide part. The sliding element includes a first part (I) and a second part (2) which is mounted so as to be rotatable relative thereto, which parts include a contact surface (3) for mutual support. The contact surface (7) is axially inclined in a rotational direction of the second part (2) counter to the first part (I), and the two parts (I, 2) can be locked to one another in various angular positions and the locking can be released.
