Inset Drawer Stop Adjustment for Precise Closing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furniture pieces with recessed drawers face challenges in defining a precise closing position due to production tolerances and installation deviations, leading to uneven appearances and lack of a suitable abutment surface for stopping the closing movement.
Innovation Solution
A device with an adjustable stop unit that includes a resiliently deflectable stop part, allowing for precise setting of the stop position through a fixed deflecting position, which can be connected to either the furniture part or the basic structure, enabling flush recessing and precise alignment of the front side with the basic furniture structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an adjustable stop is provided to define the end point of the closing movement, then the closing position can be predetermined, but for inset drawers without peripheral projections, there is no suitable abutment surface for the stop to contact
Solution Approach 1:
The stop device is segmented into two separate components: a stop element fixed to the basic furniture structure and a contact element fixed to the movable furniture part. This segmentation allows each element to be independently positioned and adjusted, enabling the stop mechanism to function effectively even when the drawer front has no peripheral projections to provide an abutment surface.
Solution Approach 2:
The invention introduces an intermediary contact element that is fixed to the movable furniture part (drawer) and serves as the actual contact surface for the stop mechanism. This intermediary element bridges the gap between the stop device and the drawer, providing a suitable abutment surface even when the drawer front itself cannot provide one.
2Manufacturing precision
If production tolerances and installation deviations occur, then the furniture part may not be located in the desired closing position, but adjusting the stop position requires complex modifications
Solution Approach 1:
The stop element is designed with dynamic adjustability, allowing its position to be modified after installation. The stop device can be adjusted along the closing movement path to compensate for production tolerances and installation deviations, enabling precise closing position accuracy without requiring complex permanent modifications to the furniture structure.
Solution Approach 2:
The invention enables parameter changes in the stop position through a simple adjustment mechanism. The stop element can be repositioned to different locations along the closing path, allowing the closing position parameters to be fine-tuned to account for manufacturing tolerances and installation variations, achieving desired accuracy through parameter adjustment rather than complex structural modifications.
3Reliability
If the stop position is fixed, then the closing position is predetermined, but adjustment for tolerances and alignment is difficult
Solution Approach 1:
The stop device incorporates dynamic adjustability while maintaining operational reliability. The stop element can be easily repositioned along the closing movement path to achieve the desired closing position, and once set, it provides consistent and reliable stopping action. This dynamic capability allows for both easy adjustment and reliable consistent operation.
Solution Approach 2:
The adjustment mechanism is designed to be self-service friendly, allowing users to easily adjust the stop position without requiring specialized tools or complex procedures. The stop element can be repositioned and secured through simple operations, enabling end users to perform alignment adjustments themselves to compensate for installation variations and achieve proper closing position consistency.
