Locking Shelf Bracket Structure for Adjustable Display Racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product display racks often have fixed shelves that require disassembly for relocation, or adjustable shelves that are not securely affixed, posing risks of injury and product damage due to unintentional displacement.
Innovation Solution
A product display rack with a U-shaped solid wire locking shelf support bracket that can be assembled without tools, allowing shelves to be securely affixed and adjusted without disassembling the entire rack, using a central catch and hook legs to pivotally attach to the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed shelves are used in product display racks, then the shelves are securely affixed to the frame, but the shelves cannot be removed or moved to a new location without disassembling and reassembling the entire product display rack
Solution Approach 1:
The locking mechanism is segmented into separate components: a locking member with a body and a locking arm that can move between locked and unlocked positions. This allows the shelf to be secured when needed while enabling easy release and repositioning without disassembling the entire rack structure.
Solution Approach 2:
The locking arm is designed to be movable rather than fixed, transitioning between a locked position where it engages with the shelf to prevent removal, and an unlocked position where it releases the shelf. This dynamic mechanism enables both secure attachment and easy adjustability within the same system.
2Ease of operation
If adjustable shelves are used in product display racks, then the shelves can be moved to new locations, but the shelves are not securely affixed to the frame resulting in unintentional displacement or removal
Solution Approach 1:
The locking member is pre-configured with the locking arm in a ready-to-engage position. When the shelf is installed or adjusted, the locking mechanism is automatically positioned to secure the shelf, ensuring security is established before use without requiring additional assembly steps.
Solution Approach 2:
The locking mechanism is designed to automatically engage and secure the shelf when installed, and can be easily released when adjustment is needed. The structure itself provides the locking and unlocking functions without requiring external tools or complex operations, making the system self-sufficient for both security and adjustability.
3Reliability
If tools or small loose fastener parts are used to assemble product display racks, then the shelves can be securely affixed to the frame, but the assembly process becomes complex and requires additional parts that are difficult to manage
Solution Approach 1:
The locking member integrates multiple functions into a single component: the body provides structural support while the integrated locking arm provides the securing mechanism. This consolidation eliminates the need for separate fasteners, screws, or tools, simplifying both manufacturing and assembly while maintaining secure attachment.
Solution Approach 2:
The locking member with its locking arm serves multiple functions: it secures the shelf to the frame, enables easy release for adjustment, and maintains structural integrity. This multi-functional design replaces multiple specialized components with a single versatile element that performs all necessary operations.

AI summary
In a product display rack including a base frame, vertical upright corner support members, and optional header cross member, at least one locking shelf support bracket member is pivotally mountable to a pair of the vertical upright corner frame members and secures at least one shelf to the product display rack.
