Stackable Container Interlocking Mechanism for Secure Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable containers lack a secure, non-sliding stacking mechanism and often require specially-crafted foam inserts for effective storage and transport of products.
Innovation Solution
The design features a container assembly with raised members on the lid and base portions that interlock securely, forming receiving areas to prevent sliding and eliminate the need for foam inserts, using rotomolded polyethylene and hermetically sealable, shock-resistant materials for enhanced structural rigidity and product protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stackable containers are used, then containers can be stacked during storage and transport, but the containers slide relative to each other and lack secure stacking capability
Solution Approach 1:
The container employs nested interlocking features where protrusions on one container fit into recesses on adjacent containers, creating a nested doll-like configuration that secures stacking while maintaining structural simplicity
Solution Approach 2:
The invention transitions from conventional flat stacking surfaces to three-dimensional interlocking surfaces with protrusions and recesses, adding dimensional complexity to the stacking interface that prevents sliding while preserving overall container simplicity
2Reliability
If foam inserts are used to prevent product movement, then products are secured during transport, but the need for specially-crafted foam inserts increases complexity and cost
Solution Approach 1:
The invention extracts the product security function from separate foam inserts and integrates it directly into the container structure through interlocking surfaces, eliminating the need for additional foam components while maintaining product security
Solution Approach 2:
The container merges multiple functions into a single integrated structure: the stacking surfaces simultaneously provide both container-to-container security and product-to-container security, replacing the need for separate foam inserts
3Ease of manufacture
If containers are designed with smooth inner surfaces for easy cleaning, then maintenance is simplified, but specially-crafted foam inserts are required to prevent product sliding
Solution Approach 1:
The container applies local quality by providing smooth surfaces in product-contact areas for easy cleaning, while incorporating localized interlocking protrusions and recesses in stacking areas to prevent sliding, achieving both cleaning ease and product stability
