Adjustable Shelf Clamping for Modular Display Assembly Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands lack flexibility in adjusting shelves, making it difficult to display different products or arrange them in various manners, as shelves are typically fixed and not easily movable or reconfigurable.
Innovation Solution
A modular display assembly with shelves that are adjustably mounted to side members via clamping arms, allowing for easy positioning and reconfiguration, and the ability to connect multiple modules to form a unified display unit, with product tray modules concealing side members for a continuous appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If shelves are fixedly attached to side walls or back of display cabinet, then structural stability is improved, but adaptability deteriorates
Solution Approach 1:
The shelf mounting system transitions from fixed attachment to adjustable positioning. The side walls include vertically spaced protrusions that engage with corresponding recesses in the shelves, allowing shelves to be positioned at multiple heights. This dynamic mounting system enables both stable attachment at selected positions and easy repositioning to different locations along the side walls.
2Adaptability or versatility
If shelves are made adjustable and movable, then adaptability is improved, but structural rigidity deteriorates
Solution Approach 1:
The side walls are segmented with vertically spaced protrusions that serve as discrete attachment points. Each protrusion engages with a corresponding recess in the shelf to provide localized structural support. This segmentation allows the shelf to be adjustable to multiple positions while maintaining structural rigidity through positive engagement at each protrusion location.
3Productivity
If multiple display modules are connected together, then productivity is improved, but device complexity deteriorates
Solution Approach 1:
Adjacent display modules are connected by joining their respective side walls through interlocking protrusions and recesses. The protrusions on one module engage with corresponding recesses on the adjacent module, creating a unified structure. This merging approach increases display capacity while minimizing connection complexity through simple geometric interlocking.
4Reliability
If mounting assemblies with multiple arms are used, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The mounting assembly includes a handle that, when moved, simultaneously actuates multiple arms to engage with protrusions on both forward and rearward edges of side walls. This preliminary action of moving the handle performs the complex multi-arm engagement operation in a single motion, ensuring reliable mounting while maintaining ease of operation.

AI summary
A modular display assembly for displaying merchandise includes a pair of opposite side members and a plurality of shelves adjustably mounted to the side members. The side members have forward and rearward facing edges, which include a plurality of protrusions spaced therealong. The shelf includes a mounting assembly, which includes a handle and first and second movable arms for mounting the shelf to the side members. The arms are configured to engage at least one of the protrusions to limit vertical movement along the side members when the arms are engaged with the edges of the side members. The shelf is positionable between the side members at a desired location and the handle is movable to move the arms into engagement with the forward and rearward facing edges to substantially clamp the side member between the arms and thus to fixedly secure the shelf to and between the side members.
