Mesh Basket Partition Locking Structure for Fast Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container dividing devices for refrigerated goods in freezers are difficult to assemble and disassemble quickly, leading to unnecessary heat and moisture flow, which complicates interior layout changes.
Innovation Solution
A container with a dividing device featuring a clip that secures a bolt with a projection extending from the partition wall, using a bolt with a head piece, crossbar, and shaft for locking, and a bracket with symmetrical legs and latching contours to prevent rotation, allowing for easy assembly and disassembly while maintaining childproof safety and minimizing weight while maximizing rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dividing device is designed to be easily assembled and disassembled for layout changes, then the ease of operation is improved, but the secure fastening and structural stability may be compromised
Solution Approach 1:
The bolt is designed with a rotatable crossbar that transitions between a passage orientation (for easy insertion) and a locking orientation (for secure fastening). This dynamic element allows the same component to serve both assembly convenience and structural reliability functions.
Solution Approach 2:
The bracket features asymmetrical design with one leg having an opening for bolt insertion and the other leg providing structural support. This local differentiation optimizes each part for its specific function while maintaining overall system reliability and ease of assembly.
2Ease of operation
If the head of the bolt is made large for easy manual operation, then the ease of operation is improved, but it impedes the placement of refrigerated goods in the basket
Solution Approach 1:
A tool such as a screwdriver or coin is introduced as an intermediary to rotate the bolt head. This allows the bolt head to remain small and non-obtrusive while still providing adequate leverage for operation through the tool interface.
3Strength
If the dividing wall is made thick for high rigidity, then the strength is improved, but the weight of the dividing wall increases
Solution Approach 1:
The dividing wall combines a thin base structure with strategically placed thicker regions (edge beads) and reinforcement elements. This composite approach achieves high rigidity where needed while minimizing overall weight through selective thickening rather than uniform increase.
Solution Approach 2:
The edge bead is made thicker than the distance between the legs of the bracket at specific locations to provide localized reinforcement. This local quality enhancement achieves the required rigidity only where structurally necessary, reducing overall weight compared to a uniformly thick wall.
4Reliability
If the bracket is designed with complex fastening mechanisms for secure attachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The bolt integrates multiple functions into a single component: the shaft provides the fastening element, the crossbar provides the locking mechanism through rotation, and the head provides the interface for tool operation. This merging reduces the number of separate parts while maintaining secure attachment reliability.
