Compact hidden hanging-bracket system for wall cupboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hidden hanging-bracket systems for wall cupboards often compromise between adjustment mechanisms and safety features, leading to excessive bulk, aesthetic issues due to visible caps, and difficulties in adjusting depth and height due to interferences between anti-disengagement and horizontal adjustment groups.
Innovation Solution
A compact hidden hanging-bracket system with a movable hooking tooth on a slide, incorporating a bevel gear mechanism for vertical adjustment and a grub screw for anti-disengagement, allowing parallel and perpendicular axes for easy access and adjustment without interference, reducing the size of holes needed in the furniture lining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both vertical adjustment mechanism and anti-disengagement device are provided according to known art, then adjustment functionality and safety are improved, but device bulk increases excessively
Solution Approach 1:
The patent combines the anti-disengagement device and vertical adjustment mechanism into a single integrated structure. The anti-disengagement lever (33) is positioned within the vertical adjustment range (20) and works in conjunction with the vertical adjustment screw (25) and toothed bar (28), eliminating the need for separate components and reducing overall bulk while maintaining both safety and adjustment functionality.
Solution Approach 2:
The vertical adjustment mechanism serves dual purposes: it enables height adjustment of the hanging bracket and simultaneously provides the anti-disengagement function. The lever (33) that engages with the toothed bar (28) for vertical adjustment also acts as the anti-disengagement device, allowing one component to perform multiple functions and reduce overall system complexity.
2Ease of operation
If adjustment mechanisms and anti-disengagement devices are provided with separate access holes, then adjustment functionality is improved, but aesthetic appearance deteriorates due to visible caps
Solution Approach 1:
The patent consolidates the access requirements for both vertical adjustment and anti-disengagement operations into a single hole in the lining. The lever (33) and vertical adjustment screw (25) are positioned such that both can be accessed through the same opening, eliminating the need for multiple visible caps and maintaining aesthetic appearance while preserving full functionality.
3Reliability
If anti-disengagement device and horizontal adjustment group are provided separately, then safety function is improved, but adjustment difficulty increases due to interferences between elements
Solution Approach 1:
The patent positions the anti-disengagement lever (33) and horizontal adjustment hook (11) in different spatial dimensions and orientations. The lever operates in a vertical plane for anti-disengagement, while the hook moves horizontally for depth adjustment. This dimensional separation eliminates interference between the two functions, allowing both safety and ease of operation to be maintained.
