Shelf Frame Structure with Segmented Ribs for Bonding Area and Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage shelf structures lack sufficient bonding area and reinforcing support due to insufficient thickness of the protective lip and reinforcing ribs, which compromises the structural integrity and durability.
Innovation Solution
A shelf structure featuring a frame member with parallel ribs and a layer member, where the reinforcement board with trims and protruding ribs is securely connected to enhance bonding strength and stability, using the upper and lower portions of the frame member to sandwich the layer member and reinforce the assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the lip is designed to shield the sharp edge of the horizontal rib to avoid injury, then safety is improved, but the bonding area between the lip and shelf becomes insufficient
Solution Approach 1:
The horizontal rib is segmented into two functional parts: the lip portion that provides safety shielding and the extended bonding area that provides sufficient attachment surface. This segmentation allows the lip to serve dual purposes - protecting against sharp edges while providing adequate bonding area for shelf attachment.
2Strength
If the reinforcing rib thickness is increased to achieve effective reinforcing support, then structural strength is improved, but the complexity of manufacturing increases
Solution Approach 1:
The reinforcing rib is merged with the horizontal rib to form an integrated structural element. This combination allows the reinforcing function to be achieved through the integrated geometry of the ribs rather than through increased thickness alone, maintaining manufacturing simplicity while providing effective reinforcement.
Solution Approach 2:
Instead of increasing thickness in one dimension, the reinforcement is achieved by extending the rib structure in planar dimensions and creating a wider bonding area. This dimensional approach provides reinforcing support without the manufacturing complexity associated with increased thickness.
3Reliability
If the bonding area is increased to improve connection strength, then joint reliability is improved, but the device complexity increases
Solution Approach 1:
The horizontal rib structure serves multiple functions simultaneously: it provides the primary structural framework, incorporates the lip for safety shielding, extends to provide bonding area, and integrates reinforcing ribs. This multi-functionality increases joint reliability without proportionally increasing device complexity.

AI summary
A shelf structure has a frame member, a layer member and at least one reinforcement board. An outer surface of the frame member has a plurality of parallel ribs and an inner surface of frame member has a contacting face between each two ribs. An upper end and a lower end of the frame member respectively has an upper portion and a lower portion parallel with each other. A lower surface of the upper portion has at least one protruding rib. The lower portion is smaller than the upper portion. The layer member is assembled in the frame member and overlaps the upper portion of the frame member. The reinforcement board has a length equal and parallel to two opposite sides of the frame member and secured to the other two opposite side of the frame member.
