Hidden Wall-Cupboard Hanging Bracket for Robotic Fixing Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hidden hanging brackets for wall cupboards cannot be automatically fixed by a robot due to the presence of oblique fixing screws, which compromises their resistance to shear and torsional stress, and those that can be automatically fixed lack sufficient resistance to these stresses.
Innovation Solution
A hidden hanging bracket with a rectangular, box-like structure featuring pins and an expansion dowel for interference fit into the shoulder and a flat tongue for secure engagement with the top, allowing robot-assisted automatic fixing to both the shoulder and top while providing resistance to shear and torsional stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If oblique fixing screws and flanges are used to fix the hanging bracket to the shoulder and top, then the resistance to shear and torsional stress is improved, but the ease of automatic fixing by robot is worsened
Solution Approach 1:
The fixing system is segmented into two distinct parts: coplanar fixing means (pins and doubles) for automatic robot fixing to the shoulder, and oblique fixing means (oblique flanges and screws) for manual fixing to the top. This segmentation allows each subsystem to optimize for its specific function without compromising the other.
Solution Approach 2:
The hanging bracket acts as an intermediary element that receives fixing from two different sources: automatic robot fixing via coplanar pins/doubles to the shoulder, and manual screw fixing via oblique flanges to the top. This intermediary structure enables both automated production and structural strength requirements to be met simultaneously.
2Ease of operation
If only coplanar pins and screws are used for fixing the hanging bracket to the shoulder, then the ease of automatic fixing by robot is improved, but the resistance to torsional stress is worsened
Solution Approach 1:
The fixing system is segmented into two distinct parts: coplanar fixing means (pins and doubles) for automatic robot fixing to the shoulder, and oblique fixing means (oblique flanges and screws) for manual fixing to the top. This segmentation allows each subsystem to optimize for its specific function without compromising the other.
Solution Approach 2:
The invention merges two different fixing approaches (coplanar automatic fixing and oblique manual fixing) into a single integrated hanging bracket system. The coplanar pins and doubles provide automatic fixing capability, while the oblique flanges and screws provide enhanced torsional resistance, combining the advantages of both methods.
3Ease of manufacture
If the hanging bracket is fixed only to the shoulder, then the ease of manufacture is improved, but the reliability under stress is worsened
Solution Approach 1:
The fixing system is segmented into two distinct parts: coplanar fixing means (pins and doubles) for automatic robot fixing to the shoulder, and oblique fixing means (oblique flanges and screws) for manual fixing to the top. This segmentation allows each subsystem to optimize for its specific function without compromising the other.
Solution Approach 2:
The invention changes the spatial orientation parameter of the fixing means by introducing oblique flanges and screws at an angle to the base, in addition to the coplanar pins and doubles. This parameter change enables the bracket to resist torsional stresses more effectively while maintaining ease of manufacture through standardized components.
