Stackable Tool Container Locking Structure for Quick Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool container systems face inconvenience in stacking due to the need to manually manipulate locking mechanisms, which can be cumbersome and laborious.
Innovation Solution
A tool container system with slidably connected locking parts on opposite sides of each container that automatically lock when stacked, eliminating the need for pre-operation of locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a first locking buckle is arranged on the cover and lies flat when not in use, then the structure is simple, but the stacking operation becomes inconvenient when the second container is stacked on the first
Solution Approach 1:
The locking buckles are pre-configured in a vertical state protruding from the container body, ready to engage with the stacking grooves before the stacking operation begins. This preliminary positioning eliminates the need to manually turn or reposition the buckles during stacking, directly resolving the contradiction between simple structure and convenient operation
Solution Approach 2:
Instead of having the locking mechanism lie flat on the cover as in conventional designs, the buckles are inverted to stand vertically and protrude outward. This inversion allows the locking parts to be automatically engaged during stacking without manual manipulation, solving the operational inconvenience while maintaining structural simplicity
2Reliability
If the first locking part is turned over before stacking, then the locking can be achieved, but the stacking process becomes laborious and time-consuming
Solution Approach 1:
The stacking containers are designed with self-locking capability where the protruding locking buckles on one container automatically engage with the corresponding stacking grooves on the other container during the stacking process itself. This self-service mechanism eliminates the need for manual turning or additional locking operations, achieving reliable locking without time loss
Solution Approach 2:
The locking buckles are pre-positioned in a vertical, protruding state that is ready to engage with the stacking grooves before stacking occurs. This preliminary configuration ensures that the locking action happens automatically during stacking, maintaining reliability while eliminating the time-consuming manual turning step

AI summary
Provided is a tool container system. The tool container system includes a first tool container and a second tool container that can be stacked. The first tool container is provided with a first locking part, the second tool container is provided with a second locking part matched with the first locking part, the first locking part is slidably connected to the first tool container, and the first locking part is accommodated in the first tool container at an accommodating position. When the second tool container is stacked on the first tool container, or when the first tool container is stacked on the second tool container, the first locking part is pulled out of the accommodating position and then turned over to a side where the second tool container is located, and the first locking part is turned over to the second locking part and locked to the second locking part.
