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 often result in unwanted rotations or torsions, and require intricate assembly processes.

Innovation Solution

A pull-out guide with a height adjustment device featuring a guide element that is integrated with the front stop or centering element, extending inclined relative to the movable guide part, allowing for easy assembly and preventing torsions, comprising a movable support member connected to the guide element that can be slidably adjusted without compromising structural integrity.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:

Improveheight adjustment capabilityVSAvoidtorsional stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The guide element is extracted as a separate component from the movable guide part, allowing it to be specifically designed for height adjustment without affecting the structural integrity of the main guide body. This separation eliminates the torsional issues that would result from modifying the hooking device structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The guide element acts as an intermediary component between the movable guide part and the drawer, providing the height adjustment function through its inclined geometry while maintaining structural stability and preventing unwanted torsions of the pull-out guide assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If adjustment means are associated with the movable guide part requiring cuts and openings, then height adjustment is achieved, but structural weakening occurs

Engineering Contradiction:

Improveheight adjustment capabilityVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The guide element is extracted as a separate component from the movable guide part, allowing it to be specifically designed for height adjustment without affecting the structural integrity of the main guide body. This separation eliminates the need for cuts and openings in the profiled element.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The height adjustment function is segmented into a separate guide element that can be independently designed and assembled, rather than integrating it into the movable guide part which would require structural modifications compromising strength.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If a separate adjustment element is provided with complex mounting requirements, then height adjustment is achieved, but assembly complexity increases

Engineering Contradiction:

Improveheight adjustment capabilityVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide element combines multiple functions (height adjustment guidance and structural support) into a single integrated component that is provided in a single piece with the front stop element and/or front centering element, simplifying assembly while maintaining adjustment capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The guide element serves multiple purposes: it provides height adjustment guidance, acts as a structural support, and integrates with the front stop or centering function, reducing the total number of components and simplifying assembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)
