Drawer Frame Tilt Adjustment With Side-Access Actuating Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer frame adjustment devices are difficult to access, especially when adjusting the inclination of front panels in closely stacked drawers, as the adjustment screws are often located in hard-to-reach areas, making the adjustment process cumbersome and inefficient.
Innovation Solution
The drawer frame incorporates a U-profile with a rear wall holder that houses the adjustment device, featuring a rotatable actuating element with a recess for tool access and a spiral worm for self-locking height adjustment, allowing the support foot to rest on the drawer pull-out guide and move linearly, facilitating easy and accessible inclination adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment screw is located in the conventional position (only accessible from above), then the adjustment mechanism is simple, but the accessibility becomes difficult especially in closely stacked drawers
Solution Approach 1:
The adjustment device is repositioned from a vertically accessible location to a horizontally accessible location on the lateral inner surface of the drawer frame. This dimensional shift allows access from the drawer interior rather than from above, solving the accessibility problem in closely stacked drawers without significantly increasing structural complexity
Solution Approach 2:
The actuating element serves as an intermediary interface between the user and the adjustment mechanism. It translates user input (manual operation) into the rotational movement needed to adjust the support foot position, making the adjustment process accessible and user-friendly
2Reliability
If the support foot is firmly connected to the drawer pull-out guide, then the stability is high, but the adjustability is reduced
Solution Approach 1:
The connection between the support foot and drawer pull-out guide is designed to be dynamically adjustable rather than statically fixed. The adjustable connection allows the drawer frame to be firmly stabilized when positioned, while still permitting repositioning when adjustment is needed, thus achieving both stability and adaptability
Solution Approach 2:
The position of the support foot on the drawer pull-out guide can be changed by adjusting its vertical position. This parameter change allows the system to transition between different stability states and adaptability states, enabling both firm connection and adjustability as needed
