Drawer Front Adjuster With Internal Access and Narrow Side Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer front adjustment mechanisms require increased installation space, are inaccessible for adjustment when the drawer is adjacent to a wall, and cannot be adjusted from within when the drawer is loaded, limiting design flexibility and usability.
Innovation Solution
A front adjustment system that allows for transverse adjustment of the front panel via a bearing body integrated into the front panel, featuring separate adjustment elements for height and side adjustment, including an adjusting wheel with internal teeth and an eccentric bolt for precise vertical and lateral movement, enabling narrower drawer frame designs and internal access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment mechanism is installed in the drawer frame side, then the front panel can be adjusted, but the drawer frame width increases and design uniformity is compromised
Solution Approach 1:
The adjustment mechanism is extracted from the drawer frame side and integrated into the front panel itself. The bearing body is fixed to the front panel, and the adjustment elements are housed within the front panel structure, eliminating the need for side frame mounting and maintaining uniform drawer frame design.
Solution Approach 2:
The adjustment mechanism is repositioned from a lateral mounting location to a front-facing location. The adjustment elements are accessible from the front of the drawer, changing the spatial dimension of access from side to front, which allows for narrower side frames while maintaining adjustability.
2Ease of operation
If the adjustment mechanism is mounted on the drawer frame, then the front panel can be adjusted, but the mechanism becomes inaccessible when the drawer is adjacent to a wall
Solution Approach 1:
The adjustment mechanism is designed with front-facing accessibility that works regardless of the drawer's position relative to walls. The bearing body and adjustment elements are configured to be accessible from the front, making the mechanism universally applicable whether the drawer is flush with a wall, protruding, or recessed.
3Ease of operation
If the adjustment mechanism is located on the drawer frame, then the front panel can be adjusted, but adjustment from inside the drawer is impossible when loaded
Solution Approach 1:
The adjustment mechanism is repositioned to allow access from the front of the drawer, enabling users to reach the adjustment elements from inside the drawer when it is pulled out. This dimensional change in accessibility allows adjustment even when the drawer is loaded, as users can access the mechanism from the front opening rather than from the sides.
4Manufacturing precision
If a gear guide mechanism is used for precise adjustment, then adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment systems with a gear guide mechanism that provides precise adjustment through a simplified design. The gear guide uses a rack and pinion arrangement where a toothed rack is guided by a gear, eliminating the need for multiple adjustment elements and complex linkages while maintaining high precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables user-friendly, precise adjustment of the front panel without increasing the drawer frame's width, allowing for a uniform design and accessibility even when the drawer is loaded or adjacent to a wall, while accommodating various materials.
Implementation Method 1
the adjustment mechanism has an adjusting wheel with internal teeth, which engages an external toothing of the first adjustment element
Implementation Method 2
the second adjustment element is preferably designed as an eccentric bolt, which enables smooth linear displacement of the adjusting bolt
