Solution Overview

Problem

Existing movement arrangements for furniture components like drawers and doors often result in complex designs with high part count and assembly complexity, leading to noise and reliability issues during operation.

Innovation Solution

A compact movement arrangement with a guide element and a second contact piece that is guided in a guideway, featuring a limiting element supported on a receptacle, which reduces part count and assembly complexity while ensuring clear and reliable movement control, and minimizing noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional movement arrangement with separate pull-in device and push-out arrangement is used, then the drawer can be moved between closed and open positions, but the design becomes complex with high part count and assembly complexity

Engineering Contradiction:
Improvedrawer movementVSAvoiddesign complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the pull-in device and push-out arrangement into a single integrated movement arrangement. The guide element serves both as a guide for the drawer and as a component for the push-out mechanism, while the contact piece integrates the limiting element and blocking part functions. This merging reduces the part count and simplifies assembly while maintaining the full functionality of moving the drawer between closed and open positions.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If multiple separate components are used for movement control, then the movement function can be achieved, but assembly complexity and part outlay increase

Engineering Contradiction:
Improvemovement controlVSAvoidassembly complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The contact piece is designed as an integrated component that combines the limiting element and blocking part into a single piece. The limiting element is formed as an extension of the contact piece body, and the blocking part is integrated into the same component. This integration significantly reduces assembly complexity and part outlay while maintaining precise movement control functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a complex mechanism with multiple parts is used, then movement control can be achieved, but noise emissions increase

Engineering Contradiction:
Improvemovement controlVSAvoidnoise emissions
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

By integrating the limiting element and blocking part into a single contact piece, the number of separate components that could potentially collide and generate noise is reduced. The streamlined design with fewer parts and smoother transitions between components minimizes impact noise and mechanical noise during drawer operation.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If separate fitting parts are used for retraction device and ejection device, then the movement function can be achieved, but the overall design becomes less compact

Engineering Contradiction:
Improvemovement functionVSAvoidoverall size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The guide element is designed to serve dual purposes: guiding the drawer movement and housing the push-out mechanism. The contact piece with integrated limiting element and blocking part reduces the number of separate components. This integration creates a more compact overall design while maintaining full movement functionality.

Inventive Principle:
Principle #5Merging (Combining)
