Concealed Shelf Bracket Support With In-Place Arm Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concealed-type support arrangements for brackets, consoles, and shelves are cumbersome and time-consuming to adjust, requiring complex operations to accurately position and incline support arms, leading to inadequate and reproducible adjustments.
Innovation Solution
A concealed-type support arrangement featuring a longitudinal mounting bracket with a movable member and guide means, allowing for simple and quick adjustment of support arms through a threaded bore and coupling mechanism, enabling longitudinal and transverse displacement without removing the shelf, and utilizing serrations for precise inclination control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shelf is removed and a force is exerted upon the shank to counterbalance the torque generated by its weight to enable horizontal adjustment, then the position of the support arm can be adjusted, but the operation becomes complicated and time-consuming requiring repetitive adjustments
Solution Approach 1:
A plate is introduced as an intermediary component between the support shank and the mounting bracket. The plate can slide along the slot in the bracket and is engaged by the shank, mediating the adjustment process. This allows the shank position to be changed without directly manipulating the heavy shank itself, reducing the force needed and simplifying the operation.
Solution Approach 2:
The system transitions from a static fixed position to a dynamic adjustable position through the plate's ability to slide along the slot. The plate's position along the slot determines the horizontal position of the support arm, enabling continuous adjustment rather than discrete fixed positions.
2Adaptability or versatility
If two dowels are provided to adjust the inclination of the support shank, then the inclination can be adjusted, but the operation requires actuating both dowels which is time-consuming and yields inadequate accuracy
Solution Approach 1:
Two separate dowel adjustment mechanisms are merged into a single integrated adjustment system. The plate's position along the slot simultaneously controls both horizontal positioning and inclination angle, eliminating the need for two separate adjustment operations and improving precision through a unified mechanism.
Solution Approach 2:
The plate serves multiple functions: it acts as a positioning element for horizontal adjustment, an inclination control element, and a mechanical link between the shank and bracket. This multi-functionality replaces the need for separate dowels for each adjustment function.
3Ease of repair
If the shelf is completely removed to actuate the dowels for inclination adjustment, then the dowels can be accessed, but the procedure becomes cumbersome and requires repetitive mounting and checking
Solution Approach 1:
The adjustment mechanism (plate and slot) is extracted and made accessible independently from the shelf. The plate can be adjusted through the slot opening in the bracket without requiring removal of the shelf, separating the adjustment function from the shelf mounting function.
Solution Approach 2:
The system allows for self-adjustment through the plate's sliding mechanism along the slot. The plate's design enables it to be manipulated through the bracket's slot opening, providing self-service adjustment capability without requiring complete disassembly of the shelf-support assembly.
