Roller Pull-Out Guide With Tilting Slide for Low-Friction Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller pull-out guides for furniture lack operational reliability with excessive parts and processing steps, and often experience increased frictional forces during the retraction process.
Innovation Solution
The introduction of a tilting slide with a gripper that directly acts on the roller to pull the furniture part in, eliminating the need for additional catches and minimizing friction by engaging only during the contacting process, and using coupling parts for the retraction process to reduce frictional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional catches such as hooks are used for the tilting slide to act on, then the retraction mechanism can be implemented, but the number of parts increases and processing steps are added
Solution Approach 1:
The patent combines the function of the catch with the roller itself by providing a gripper that directly acts on the roller. The roller serves both as a moving element and as the engagement point for the self-closing device, eliminating the need for separate catches or hooks. This merging of functions reduces the number of parts while maintaining operational reliability.
2Ease of operation
If the gripper rests on the roller during the insertion process, then the furniture part can be pulled in, but frictional forces increase
Solution Approach 1:
The patent employs dynamic engagement where the gripper only contacts the roller when needed for retraction, not continuously during insertion. The tilting slide mechanism allows the gripper to engage and disengage dynamically based on the operational phase, reducing unnecessary friction during the insertion process while maintaining effective retraction capability.
