Integrated Sliding Arrangement for Reliable Soft-Closing Drawers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding arrangements for drawers and sliding doors lack high operating safety, particularly in handle-less designs, as they do not ensure reliable mechanical adjustments and can result in hard impacts during closure.
Innovation Solution
A sliding arrangement with a structural unit that includes adjustable mounting on furniture parts, a tilting element for easy connection, and a spring-loaded actuating element with a freewheel mechanism for controlled operation, allowing for precise adjustment and safe operation by coupling the ejection and retraction devices through a displaceable actuating element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding arrangement is used in handle-less drawers, then ease of operation is improved, but operating safety deteriorates due to lack of mechanical adjustment control and risk of hard impacts
Solution Approach 1:
The patent implements a mechanical feedback system through the actuating element that provides tactile and positional feedback to the user. The actuating element moves between defined positions (retracted, intermediate, parked) and can be felt by the user, allowing intuitive control without visual confirmation or handles. This feedback mechanism ensures the user understands the state of the sliding arrangement while maintaining operating safety through controlled mechanical sequences.
Solution Approach 2:
The patent employs dynamic mechanical components including a tilting element that pivots between blocked and released positions, and an actuating element that transitions between multiple positions. These dynamic elements enable the system to adapt its mechanical state based on operational phase, providing both ease of operation and safety through controlled movement sequences rather than static mechanical connections.
2Adaptability or versatility
If multiple separate components are used for slide-out and retraction devices, then adaptability is improved, but device complexity increases and manufacturing precision becomes more difficult to guarantee
Solution Approach 1:
The patent combines the slide-out arrangement and retraction device into a single integrated structural unit mounted on one furniture part. The coupling part serves both the slide-out mechanism and the retraction device, while the actuating element controls both functions. This merging reduces the number of separate components, simplifies assembly, and allows factory pre-adjustment of the entire mechanism, guaranteeing reliable operation while maintaining adaptability through the integrated design.
Solution Approach 2:
The actuating element serves multiple functions: it controls the coupling between slide-out and retraction devices, provides mechanical feedback, and enables both extension and retraction operations. The coupling part also serves dual purposes by connecting both the slide-out arrangement and retraction device. This multi-functionality reduces overall device complexity while maintaining the adaptability needed for different operational phases.
3Ease of operation
If the actuating element is spring-loaded in the parked position, then ease of operation is improved through automatic return, but device complexity increases due to additional spring mechanism
Solution Approach 1:
The spring-loaded actuating element implements self-service by automatically returning to its parked position after use. When the user releases the actuating element from the intermediate position, the spring automatically propels it back to the parked position, preparing the system for the next operation without requiring manual intervention. This self-service feature improves ease of operation while the spring mechanism is integrated into the existing structural unit, minimizing additional complexity.
