Pull-Out Guide Height Adjustment Without Torsional Weakening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pull-out guides for drawers face issues with complex construction and structural weakening due to the need for height adjustment, which can cause unwanted rotations or torsions and complicate assembly.
Innovation Solution
A pull-out guide with a height adjustment device featuring a guide element and support member integrated in a single piece with the front stop or centering element, extending inclined relative to the movable guide part, allowing for easy assembly and preventing torsions by separating the adjustment mechanism from the movable guide part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustment means are associated with the hooking device using a wedge element, then height adjustment is achieved, but rotations or unwanted torsions of the pull-out guide occur
Solution Approach 1:
The patent extracts the height adjustment function from the hooking device by introducing a separate movable support member that slides on the guide element. This separation prevents the torsional issues caused by wedge elements while maintaining the height adjustment capability through the independent movement of the support member along the inclined guide element.
2Adaptability or versatility
If adjustment means are associated with the movable guide part using an adjustment element, then height adjustment is achieved, but construction complexity increases and structural strength decreases
Solution Approach 1:
The patent merges the guide element for the movable support member with the front stop element and/or front centering element into a single integrated component. This combination reduces construction complexity by eliminating separate parts and simplifies assembly while maintaining the height adjustment function through the movable support member's interaction with the integrated guide element.
3Adaptability or versatility
If adjustment means are associated with the movable guide part using an adjustment element, then height adjustment is achieved, but structural strength is weakened due to cuts and openings
Solution Approach 1:
The patent segments the height adjustment function from the main movable guide part structure by using a separate movable support member that slides on an external guide element. This segmentation avoids the need for cuts and openings in the profiled element of the guide, thereby maintaining structural strength while enabling height adjustment through the independent support member mechanism.
4Adaptability or versatility
If a separate adjustment mechanism is used, then height adjustment is achieved, but assembly complexity increases
Solution Approach 1:
The patent combines the guide element for the movable support member with the front stop element and/or front centering element into a single integrated component. This merging simplifies assembly by reducing the number of separate parts that need to be assembled and eliminates the need for complex alignment procedures, while still providing the height adjustment function through the movable support member.
