Concealed tear-resistant hanging-bracket group with precise depth adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concealed hanging brackets lack tear resistance, precision in depth adjustment, and rigidity, especially when subjected to stress, due to inadequate thread resistance and positioning issues with separate molded elements and holes in the base plate.
Innovation Solution
A concealed tear-resistant hanging-bracket group with precise depth adjustment, featuring a single moulded plate element with integrated fixing pins, a hooking element, and adjustable movement means, including a screw-nut mechanism and anti-disengagement device, accessible from the rear for assembly, ensuring secure and precise attachment to the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate molded elements are used for threaded holes, then manufacturing is easier, but tear resistance deteriorates
Solution Approach 1:
The patent merges the base plate and threaded holes into a single monolithic element produced from one mold. This integration eliminates the weakness of separate molded elements by creating a unified structure where the threaded holes are formed directly in the molded base plate, significantly improving tear resistance while maintaining manufacturing efficiency through single-mold production.
2Ease of manufacture
If holes are formed directly in the sheet of the base plate, then manufacturing is simpler, but positioning precision deteriorates
Solution Approach 1:
The patent applies preliminary action by forming the threaded holes directly during the molding process itself, rather than as a subsequent operation. The mold includes dedicated cavities and cores that pre-position the threaded holes with high precision during base plate formation, eliminating later positioning errors while keeping the manufacturing process simple and integrated.
3Device complexity
If the sheet is used for both blocking and adjustment threaded elements, then device complexity is reduced, but rigidity deteriorates
Solution Approach 1:
The patent segments the base plate structure by providing distinct, optimized regions: one area with threaded holes for blocking elements and another with a different configuration for adjustment elements. This segmentation allows each region to be structurally optimized for its specific function, maintaining overall rigidity while supporting multiple threaded elements without requiring additional reinforcement components.
4Device complexity
If a single plate element is used, then device complexity is reduced, but positioning precision deteriorates
Solution Approach 1:
The patent creates a universal base plate that integrates multiple functions: it provides structural support, contains precisely positioned threaded holes for both blocking and adjustment elements, and serves as the mounting surface for the hanging bracket. This multi-functional design achieves high positioning precision through integrated mold cavities while maintaining simplicity as a single plate element without requiring separate positioning components.
