Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
3Ease of operation
If a complex mechanism with multiple parts is used, then movement control can be achieved, but noise emissions increase
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.
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
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.

AI summary
The invention relates to a movement assembly, in particular for a drawer, a sliding door, a hinged door, a flap or a similar movable furniture part, comprising a push-out assembly, the push-out assembly having a guide element (90), on which a stored energy source (80) acts, the guide element (90) being movable by means of the stored energy source (80) from a parking position into an ejection position, and a switching piece (99), which can be moved relative to the guide element (90), being connected to the guide element (90). According to the invention, for improved motion control, the switching piece (99) has a guide element (99.4), which is guided in a guide track (74) of the fitting part.
