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 molded elements and holes in the base plate.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate molded elements are made integral with the base plate, then the structure becomes more compact, but thread resistance deteriorates due to possible tear
Solution Approach 1:
The base plate is segmented into a main plate body and separate reinforcing elements (gussets or stiffeners) that are strategically positioned to strengthen threaded holes without being made integral with the entire plate. This segmentation allows the reinforcing elements to be placed only where needed to prevent tear while maintaining overall structural integrity.
Solution Approach 2:
The base plate incorporates composite construction by combining the main plate material with reinforcing elements of different material properties or configurations. These reinforcing elements are designed to specifically enhance thread resistance in critical areas while maintaining the compactness of the overall structure.
2Ease of manufacture
If holes are formed directly in the sheet of the base plate, then the manufacturing process is simplified, but positioning precision deteriorates
Solution Approach 1:
The base plate includes pre-formed positioning features such as定位 holes, recesses, or protrusions that are created during the stamping or forming process. These preliminary features ensure precise positioning of adjustment elements and tools before final assembly, eliminating the need for post-manufacturing drilling or machining while maintaining manufacturing simplicity.
Solution Approach 2:
The base plate incorporates localized reinforcing features or thickened areas around critical hole locations. This local quality enhancement provides precise positioning and structural strength at specific points without requiring the entire plate to be more complex or difficult to manufacture.
3Device complexity
If the sheet is used without additional reinforcing elements, then the device complexity is reduced, but rigidity deteriorates when exposed to stress
Solution Approach 1:
The base plate integrates reinforcing elements as integral parts of the same component rather than separate attachments. These reinforcing features (such as gussets, stiffeners, or thickened sections) are formed as part of the stamping process, merging the structural and reinforcing functions into a single component that maintains rigidity under stress without increasing device complexity.
Solution Approach 2:
The base plate incorporates variations in thickness, density, or material properties at specific locations to enhance rigidity where needed. These parameter changes are achieved through progressive stamping or forming processes that create locally reinforced areas without requiring additional components, maintaining simplicity while improving stress resistance.
4Manufacturing precision
If guiding holes are provided for precise positioning, then positioning precision is improved, but the sheet rigidity deteriorates due to additional holes
Solution Approach 1:
The guiding holes are designed as pre-formed features with precise dimensions and locations created during the base plate manufacturing process. These preliminary holes incorporate reinforcing rims or thickened edges that maintain sheet rigidity while providing the necessary positioning precision for adjustment elements and tools.
Solution Approach 2:
The guiding holes incorporate composite construction by combining the base plate material with locally reinforced structures around the hole perimeters. This composite approach at the hole level provides precise guiding functionality while maintaining overall sheet rigidity through strategic reinforcement that does not compromise the hole's positioning function.

AI summary
A concealed tear-resistant hanging-bracket group with precise depth adjustment for assembling a wall cupboard to a wall includes a plate and a hooking element. The plate has a plurality of fixing pins for engagement to a shoulder of the wall cupboard, and the hooking element couples the hanging-bracket group to a supporting element fixed to the wall. The hanging-bracket group is adjustable in depth and height by action of horizontal and vertical movement members. The horizontal movement member includes a threaded hole formed in a protrusion in the plate and a grub screw received in the threaded hole, a rotation of the grub screw causing a depth adjustment A guiding member for a screwdriver is coupled to the plate and includes a guiding element positioned in a pass-through opening of the plate, below and adjacent to the protrusion.
