Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable cases cannot efficiently stack cases of different sizes without causing damage or occupying excessive space, and the handle mounting process often leads to leakage issues due to piercing.
Innovation Solution
A stackable case design featuring geometric protrusions and recesses with adjustable angles and patterns, allowing transverse and longitudinal stacking, and handle mounting without piercing, using bands and inserts to distribute loads and prevent deformation and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cases are designed with fixed stacking patterns, then stacking stability is improved, but adaptability to different case sizes deteriorates
Solution Approach 1:
The stacking pattern is made adjustable through rotating elements that can change orientation between longitudinal and transverse positions. This dynamic adjustment allows the same case design to adapt to different case sizes while maintaining stable stacking configurations, resolving the contradiction between fixed stability and size adaptability.
2Ease of manufacture
If handles are mounted by piercing the case, then ease of manufacture is improved, but reliability deteriorates due to leakage
Solution Approach 1:
A rear plate is introduced as an intermediary component between the handle and the case body. The handle is mounted on the rear plate rather than directly piercing the case, which prevents leakage while simplifying the manufacturing process. The rear plate serves as a mediator that maintains both reliability and ease of manufacture.
3Device complexity
If high stacking is done unidirectionally, then stacking simplicity is improved, but stability deteriorates as cases may tumble down
Solution Approach 1:
The stacking system uses asymmetric protrusions and recesses that can engage in multiple orientations. By designing the stacking interfaces with asymmetric features that work in both longitudinal and transverse directions, the system enables bidirectional stacking patterns that prevent tumbling while maintaining relatively simple stacking procedures.
4Volume of moving object
If cases of different sizes are stored together, then space utilization is improved, but stacking compatibility deteriorates
Solution Approach 1:
The case design incorporates universal stacking interfaces with adjustable patterns that can accommodate multiple case sizes. The rotating stacking elements can be positioned to create different engagement configurations, allowing cases of varying dimensions to be stacked together efficiently, thus achieving both space utilization and stacking compatibility.

AI summary
The present invention relates to a stackable case (1), which enables cases of different sizes to be stacked in the vehicle and transported or stored and which can be stacked transversely and longitudinally. Basically, stacking feature is attained by engagement of the protrusions (5) provided on the lid (3) with the recesses (6) provided on the bottom of the body (2), and strength and endurance is achieved by the bands (4) provided on the lid (3) and the combined recesses (7) provided on the bottom of the body (2). Handles (8) are mounted to facilitate carrying of the stackable case (1) and leakage problems are prevented by performing this mounting process without carrying out piercing and cutting operations.
