Single-Sheet Packing Structure With Interlocking Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packing members formed from a single sheet material struggle to maintain a stable three-dimensional shape due to slits, cutouts, and projections, leading to potential displacement and instability.
Innovation Solution
A packing member design featuring a floor, first side wall with a through-hole and tongue segment, and second side walls with projection segments and slits, allowing for secure engagement with another packing member through projections and slits to maintain structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a packing member is formed by bending a single sheet material with slits, cutouts, and projections, then it can be manufactured from one piece, but it struggles to maintain a stable three-dimensional shape and may displace
Solution Approach 1:
The packing member is divided into multiple functional segments: a floor, first side walls with through-holes, and second side walls with projection segments and slits. This segmentation allows each part to perform its specific function while maintaining overall structural stability through the coordinated interaction of these segments.
Solution Approach 2:
The projection segments of the second side walls are inserted into the through-holes of the first side walls, creating a nested structure. This nesting mechanism provides mutual support between different parts of the packing member, preventing displacement and maintaining three-dimensional shape stability.
2Reliability
If the packing member uses projections and slits for engagement, then it can secure engagement with other packing members, but the structure becomes more complex
Solution Approach 1:
The projection segments and slits are integrated directly into the sheet material structure during the bending process, merging the engagement function with the structural components. This eliminates the need for separate engagement mechanisms while maintaining secure connection between packing members.
Solution Approach 2:
The packing member design allows the projection segments and slits to automatically engage with corresponding features on other packing members without requiring additional fasteners or complex assembly mechanisms. The structure serves its own engagement needs through the inherent geometric features.

AI summary
A packing member formed by bending a single sheet material includes a floor, a first side wall, and a pair of second side walls. The first side wall has a through-hole penetrating it in the first direction. The pair of second side walls have projection segments and slits. The projection segments are inserted in the through-hole and project outward in the first direction beyond the first side wall. The slits are formed at a position adjacent to the outer surface of the first side wall of the projection segments with the projection segments inserted in the through-hole and the slits have opening edges at the ends of the projection segments close to the floor and extend in the direction away from the floor up to a predetermined position.
