System comprising a mounting clip and an adjustable shelf system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable shelf systems face challenges with screw fixation, requiring exact screw lengths, difficulty in angular attachment due to melamine shelves' hard surface, and complex re-adjustment processes, leading to potential instability and safety hazards.
Innovation Solution
A mounting clip system that automatically locks the shelf board in place between the bracket and rail without screws, using angled designs and spring force for secure fixation, allowing for easy re-adjustment and removal without damaging the shelf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the shelf board to the bracket, then the fixation is secure and strong, but the process becomes complex requiring exact screw lengths, pre-drilling, and multiple tools
Solution Approach 1:
The invention extracts the screw fixation mechanism entirely from the shelf mounting system. Instead of using screws, the system employs a bracket with a groove and a shelf board with a corresponding protrusion that engages directly into the groove, eliminating the need for screws, pre-drilling, and multiple mounting tools while maintaining secure fixation.
Solution Approach 2:
The invention introduces a groove-protrusion interface as an intermediary mechanism between the bracket and shelf board. This intermediate structural feature enables direct mechanical engagement without requiring threaded fasteners, simplifying the mounting process while ensuring stable connection.
2Strength
If the shelf board is placed close to the rail for stability, then the fixation is stronger, but re-adjustment becomes difficult requiring all screws to be unscrewed
Solution Approach 1:
The invention segments the connection mechanism into individual groove-protrusion engagement points along the shelf board. Each section can be independently disengaged by lifting the shelf board vertically, allowing selective re-adjustment without requiring complete disassembly of all fixation points, thus facilitating easier height changes while maintaining strong fixation.
Solution Approach 2:
The groove-protrusion interface is designed to be dynamically adjustable. The shelf board can be easily inserted into and removed from the bracket's groove by vertical movement, enabling quick re-positioning at different heights without complex unscrewing operations, while the engaged state provides stable fixation.
3Ease of repair
If the shelf board is placed far from the rail for easy re-adjustment, then re-positioning is simpler, but the fixation strength decreases and objects may fall
Solution Approach 1:
The connection system uses multiple groove-protrusion engagement points distributed along the shelf board length. This segmentation allows the shelf to maintain strong fixation at each contact point even when positioned farther from the wall, while still enabling easy re-adjustment through simple vertical lifting at any location.
4Strength
If screws are used to fix the shelf board, then secure fixation is achieved, but the hard melamine surface makes screwing difficult requiring considerable force and precise angular attachment
Solution Approach 1:
The invention completely removes the screwing operation from the mounting process. The groove-protrusion design allows the shelf board to be attached by simply aligning and inserting it into the bracket, eliminating the need to overcome the hard melamine surface resistance associated with screw driving, while achieving secure fixation.
5Ease of operation
If no fixation is used and the shelf board is just placed on the brackets, then the mounting is simple, but the shelf becomes unstable under load or when children climb on it
Solution Approach 1:
The invention extracts the complexity of screw fixation while retaining the security of strong attachment. The groove-protrusion mechanism provides passive mechanical locking that secures the shelf board firmly to the bracket, preventing tilting or detachment under load or during climbing, while maintaining mounting simplicity through tool-free engagement.
Solution Approach 2:
The groove-protrusion interface acts as an intermediary mechanical lock between the shelf board and bracket. This intermediate structure provides reliable engagement that prevents the shelf from tilting or detaching under various loads, including the dynamic loads from children climbing, while keeping the mounting process simple and tool-free.

AI summary
The invention is a mounting clip for adjustable shelf systems, which ensures reliable and durable fixing of adjustable shelf boards (29) without leaving any screw holes or marks on the board and also provides a possibility to dismount shelf boards (29) by being re-adjustable in the same or different location. The mounting clip automatically locks its position between the shelf board (29) and upper part of the rail opening (31). When the clip reaches its final position the wings (2) will pass through the opening (30) and create a snap in fixation.
