Snap-Fit Container Locking Mechanism for Stable Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container stacking technologies face instability and risk during storage and transportation due to the smooth surfaces of plastic tool boxes and cases, leading to sliding and tipping issues.
Innovation Solution
A locking connecting device is introduced, featuring a fitting member on one container and a locking mechanism on the other, allowing for releasable snap-fitting to secure containers together, enabling safe stacking and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If simple stacking is used for tool boxes and cases, then storage space is reduced, but the stacking becomes unstable and containers slide or tip over
Solution Approach 1:
The locking connecting device is divided into separate components: a locking mechanism with a locking block and a fitting member with a groove. This segmentation allows the locking function to be integrated into the container structure while maintaining stacking stability through the interlocking of these discrete elements.
Solution Approach 2:
The locking block is disposed within the container body and nests into the fitting member's groove during stacking. This nested configuration allows the locking mechanism to be integrated into the container structure without adding external bulk, enabling stable stacking while optimizing storage space.
2Volume of moving object
If containers are stacked at high height to reduce storage space, then space efficiency improves, but the risk of tipping and instability increases
Solution Approach 1:
The locking mechanism is pre-configured within the container structure, with the locking block positioned to automatically engage with the fitting member's groove when containers are stacked. This preliminary arrangement ensures that stability measures are already in place before stacking occurs, enabling safe high-height stacking.
Solution Approach 2:
The locking block acts as an intermediary element between the upper and lower containers. It physically connects the two containers through the fitting member's groove, creating a reliable mechanical bond that prevents sliding and tipping even at high stacking heights.
3Reliability
If containers are securely locked together for stable transportation, then transportation safety improves, but the ability to separate containers when needed decreases
Solution Approach 1:
The locking mechanism is designed with movable components that can dynamically transition between locked and unlocked states. The locking block can be displaced from the fitting member's groove to unlock, and this dynamic capability is integrated into the container structure, allowing easy separation while maintaining secure locked positioning during transportation.

AI summary
A locking connecting device and a combined container are provided. The locking connecting device includes a fitting member and a locking mechanism. The locking mechanism is configured to be releasably snap-fitted to the fitting member, enabling the locking connecting device to switch between a locked state and an unlocked state. When the locking mechanism is operated to enable the locking connecting device to be in the locked state, the locking mechanism and the fitting member are snap-fitted to each other to prevent the first container and the second container combined with each other from being separated from each other. When the locking mechanism is operated to enable the locking connecting device to be in the unlocked state, the locking mechanism and the fitting member are released from each other to enable the first container and the second container combined with each other to be separated from each other.
