Solution Overview

Problem

Existing hidden hanging-bracket systems for wall cupboards often compromise between adjustment mechanisms and anti-disengagement safety, resulting in excessive bulk, difficulty in adjustments, and aesthetically unacceptable visible caps due to required hole sizes for access.

Innovation Solution

A compact hidden hanging-bracket system with a movable hook and integrated vertical and horizontal adjustment mechanisms, where the anti-disengagement group is positioned between the vertical and horizontal adjustment groups, using parallel and perpendicular axes to allow for easy access and reduced hole sizes, ensuring safety and aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If both vertical adjustment mechanisms and anti-disengagement devices are provided according to known art, then safety and adjustability are improved, but the hanging bracket becomes excessively bulky and complex

Engineering Contradiction:
ImprovesafetyVSAvoidhanging bracket bulk
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the anti-disengagement device and vertical adjustment mechanism into a single integrated grub screw assembly. The grub screw simultaneously performs both functions: it provides anti-disengagement by engaging with the hook and prevents unintended movement, while also enabling vertical adjustment when rotated. This merging eliminates the need for separate components, significantly reducing the hanging bracket's bulk and complexity while maintaining both safety and adjustability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The grub screw is designed as a multi-functional element that serves multiple purposes: it acts as an anti-disengagement device, a vertical adjustment mechanism, and a positioning element. This universal component approach allows the hanging bracket to achieve multiple functions with a single element, reducing overall device complexity and size.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If adjustment mechanisms and anti-disengagement devices are provided with separate access holes, then adjustment and safety functions are improved, but the hole size and visible caps become excessively large affecting aesthetics

Engineering Contradiction:
Improveadjustment functionVSAvoidhole size in lining
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent merges the access requirements for adjustment and anti-disengagement functions into a single access hole. The grub screw assembly is positioned such that both the adjustment slot and the anti-disengagement engagement point are accessible through the same opening in the furniture lining. This eliminates the need for multiple separate holes and large caps, significantly reducing the visual impact on the furniture's appearance while maintaining full adjustability and safety functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If anti-disengagement devices and horizontal adjustment groups are provided separately, then safety and positioning functions are improved, but interference between elements makes depth adjustment difficult

Engineering Contradiction:
Improveanti-disengagement safetyVSAvoiddepth adjustment ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates the anti-disengagement device with the horizontal adjustment mechanism by positioning the grub screw assembly such that it cooperates with both the hook for anti-disengagement and the horizontal adjustment elements. This integration ensures that the anti-disengagement function and horizontal positioning work together without interference, allowing smooth depth adjustment while maintaining safety.

Inventive Principle:
Principle #5Merging (Combining)
