Concealed Hanging-Bracket Assembly with Integrated Adjustment Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concealed hanging brackets for wall cupboards require multiple separate moulded pieces that increase production and assembly costs, and lack easy access to adjustments during assembly and stress events.
Innovation Solution
A concealed hanging-bracket group with anti-disengagement features a single moulded sheet plate incorporating adjustable screw-nut mechanisms and anti-disengagement means, accessible through a pair of holes in the furniture lining, allowing for easy assembly and secure attachment with minimal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate moulded pieces are used to form the hanging bracket, then the structural complexity and functionality are improved, but the production costs and assembly costs increase
Solution Approach 1:
The patent merges multiple separate moulded pieces (base plate, adjustment mechanism, anti-disengagement means) into a single integral moulded piece. This combining approach maintains all necessary functionalities while eliminating the need for separate production and assembly operations, thereby reducing production costs and simplifying manufacturing processes.
Solution Approach 2:
The single moulded piece is designed to perform multiple functions simultaneously: it provides the base plate structure, incorporates the adjustment mechanism for hooking element positioning, and includes the anti-disengagement means. This multi-functionality approach eliminates the need for separate components while maintaining structural complexity and adaptability.
2Adaptability or versatility
If multiple separate moulded pieces are joined to the base plate, then the functionality is improved, but the assembly costs and production complexity increase
Solution Approach 1:
The patent combines multiple functional elements into a single moulded piece, eliminating the need for joining separate components. This reduces assembly complexity from multiple joining operations to a single installation step, while preserving all necessary functionalities through integrated design.
3Area of stationary object
If a single hole is provided in the lining for access to adjustments, then the perforated surface area is reduced, but the ease of access to adjustments is worsened
Solution Approach 1:
The patent transitions from a two-dimensional single hole access to a three-dimensional cavity structure. The cavity provides internal space that allows easy access to both adjustments through the single hole, effectively adding a spatial dimension that resolves the conflict between minimizing surface area and maximizing accessibility.
4Reliability
If separate moulded pieces are used, then the anti-disengagement functionality is improved, but the production costs and assembly requirements increase
Solution Approach 1:
The patent integrates the anti-disengagement means directly into the single moulded piece, maintaining its functionality as a separate functional element while eliminating the need for separate production and assembly. The anti-disengagement features are formed as integral parts of the base plate structure.
