Storage Case Skeleton Frame Design to Reduce Packing Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing storage case design requires a larger footprint for packing due to the frame-forming body's wider area, leading to increased space usage as the number of tiers increases, necessitating a solution for efficient space-saving in the packing form.
Innovation Solution
A storage case with a skeleton frame that allows vertical stacking, featuring side frames, connecting members, and a top plate, where the side frames include vertical pillar portions, lower frame portions, and connecting members to support the case, and the use of a back panel and guide ribs for stability and space optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the frame-forming body is designed to support the entire bottom wall of the drawer case, then the structural stability is improved, but the packing space increases due to the larger area required
Solution Approach 1:
The bottom support function is segmented from a single large frame-forming body to multiple smaller support elements (corner supports and intermediate supports) distributed at strategic locations. This segmentation allows the bottom wall to be supported effectively while reducing the overall footprint area of each individual support component, enabling more compact vertical stacking during packing.
Solution Approach 2:
Instead of providing uniform support across the entire bottom wall area, the support structure concentrates strength at critical local points where the drawer case corners and intermediate sections contact the frame-forming body. This local quality approach maintains structural stability through strategic reinforcement while minimizing the total area occupied by support elements.
2Area of stationary object
If the frame-forming body area is increased to ensure adequate support coverage, then the support coverage is improved, but the vertical stacking efficiency deteriorates
Solution Approach 1:
The support coverage is achieved through multiple discrete support points rather than a single large continuous area. Corner supports and intermediate supports are distributed throughout the drawer case base, providing comprehensive coverage while maintaining a compact overall footprint that enables efficient vertical stacking of multiple drawer cases.
Solution Approach 2:
The support structure transitions from requiring large horizontal area coverage to achieving support through vertical positioning and strategic point distribution. By optimizing the vertical arrangement and horizontal spacing of support elements, adequate coverage is provided without increasing the horizontal footprint, thus improving vertical stacking efficiency.

AI summary
In the present invention of a storage case, a space can be saved in the packing form.The skeleton frame of the storage case includes a pair of left and right side frames, a connecting pipe connecting the front end portions of the side frames, and a back panel connecting the rear end portions of the side frames. Therefore, in the skeleton frame, the bottom wall of the case can be supported by the support portion of the side frame without providing the bottom plate that supports the entire bottom wall of the case. As a result, when the storage case is disassembled, it is not necessary to vertically stack the bottom plates that receive the entire bottom wall of the case from below, so that it is possible to save space in the packing form of the storage case.
