Drawer system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture drawer systems require pre-assembly knowledge of drawer types to position pull-out guides correctly, leading to accessibility issues and cumbersome reassembly when drawer arrangements need to be changed.
Innovation Solution
The system allows for uniform attachment of drawers to pull-out guides using front panels with distinct types, where the locking position is determined by the panel type, either through a direct or indirect stop, enabling automatic adaptation of the latching position without manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pull-out guide is positioned further forward on the furniture body to accommodate a front pull-out drawer, then the drawer is accessible when closed, but the pull-out guide cannot be universally positioned without knowing the drawer type in advance
Solution Approach 1:
The system provides dynamic adaptability through multiple locking positions (first locking position for front pull-out, second locking position for internal pull-out) on the pull-out guide, allowing the guide to be configured for different drawer types. The front panel type determines which locking position is engaged, enabling the same pull-out guide to serve both drawer types without repositioning.
Solution Approach 2:
The invention changes the positional parameter of the drawer relative to the furniture body by providing two distinct locking positions on the pull-out guide. The first locking position positions the drawer for front pull-out accessibility, while the second locking position positions it for internal pull-out. This parameter change is automatically determined by the front panel type.
2Adaptability or versatility
If the pull-out guide is repositioned to accommodate a different drawer type, then the new drawer type fits properly, but the pull-out guide must be removed and reinstalled
Solution Approach 1:
The pull-out guide is designed with universal functionality to accommodate both front pull-out and internal pull-out drawer types through multiple locking positions. The same pull-out guide can be used for different drawer types by simply changing which locking position is engaged, eliminating the need for repositioning or reinstalling the guide.
Solution Approach 2:
The system enables self-service drawer type adaptation through the automatic determination of locking position based on front panel type. The drawer itself determines the appropriate locking position through its front panel design (with or without stop), eliminating the need for manual reconfiguration of the pull-out guide when changing drawer types.
3Device complexity
If the drawer is locked in a fixed position on the pull-out guide, then the locking mechanism is simple, but the drawer arrangement cannot be changed later
Solution Approach 1:
The locking mechanism is designed with dynamic adaptability through multiple locking positions (first and second locking positions) on the pull-out guide. While each individual locking position provides simple mechanical engagement, the system as a whole offers flexibility by allowing switching between positions based on drawer type or arrangement requirements.
4Manufacturing precision
If manual adjustment of locking position is required, then precise positioning is achieved, but manual intervention is needed during assembly
Solution Approach 1:
The system achieves self-service automatic determination of locking position based on front panel type. The drawer's front panel design (with stop for internal pull-out, without stop for front pull-out) automatically determines which locking position is engaged during assembly, eliminating the need for manual intervention while maintaining precise positioning.
