Stackable Storage Containers With Tri-State Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage container systems lack an efficient and easy way to stack and secure multiple containers together, leading to disorganization and difficulty in managing tools and equipment in industrial settings.
Innovation Solution
A system of stackable storage containers with a tri-state lock mechanism that automatically aligns and locks containers using deep chamfers and protrusions, along with a lock status indicator for easy assembly and disassembly, allowing for secure stacking without manual locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual locking mechanisms are used to secure stacked containers, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The stacking system employs self-locking mechanisms where protrusions on the bottom container automatically engage with recesses on the top container when stacked, eliminating the need for manual locking operations while maintaining secure connection
Solution Approach 2:
The patent replaces complex manual locking mechanisms with a simplified geometric interlocking system using protrusions and recesses that lock automatically through mechanical engagement, reducing operational complexity while maintaining security
2Reliability
If complex locking mechanisms are used to secure containers, then reliability is improved, but device complexity worsens
Solution Approach 1:
The patent extracts the essential locking function from complex multi-component mechanisms, isolating only the critical protrusion-recess engagement elements needed for secure stacking, thereby simplifying the overall device structure
Solution Approach 2:
The protrusion and recess features serve multiple functions simultaneously: alignment guidance, secure locking, and stack stability, eliminating the need for separate dedicated locking components and reducing overall device complexity
3Productivity
If containers are designed for easy stacking, then productivity is improved, but manufacturing precision worsens
Solution Approach 1:
The patent employs asymmetric protrusion and recess geometries with specific orientation requirements, which guide precise alignment during stacking while the asymmetric design itself compensates for minor manufacturing variations through self-correcting engagement
4Ease of operation
If automatic alignment features are added to improve stacking ease, then ease of operation is improved, but device complexity worsens
Solution Approach 1:
The patent merges the alignment function with the locking function by integrating guide surfaces into the protrusion-recess structure itself, eliminating separate alignment mechanisms and maintaining simplicity while achieving easy automatic alignment

AI summary
A method and a system are disclosed including a stackable storage container. In various embodiments, the stackable storage container includes stacking locks that may be deployed automatically to lock the stackable storage containers together when a first storage container is placed upon the top of a second storage container. A tri-state locking system is used to lock the containers in a stack configuration. Deep chamfers at bottom surfaces and top lids of storage containers allow automatic alignment of the containers. When storage containers are stacked and aligned, a lock status indicator is activated to indicate the state of the stacking locks. The lock status indicator may also have an added function to allow a user to unlock the stacked storage containers to detach and remove them from the stack. The user may not manually lock the storage containers but the user may unlock them manually.
