Snap-Fit Container Wall Locking Mechanism for Reconfigurable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage containers face issues with space inefficiency, limited accessibility, and structural integrity when storing smaller items, especially when larger containers are used, due to rigid designs and inadequate locking mechanisms.
Innovation Solution
A locking mechanism comprising three interconnectable elements - a first element with a latch, a second element with a protruding locking element, and a third element with a spring element - that allows side walls to collapse, pivot, or be removed, providing a tool-free, snap-fit design for secure closure and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid storage containers are used, then structural integrity is maintained, but space efficiency and flexibility are reduced
Solution Approach 1:
The container is divided into modular wall elements that can be independently connected and disconnected. Each wall element can be separately locked or unlocked, allowing the container to be configured in different states (fully assembled, partially disassembled, or completely broken down) while maintaining structural integrity when locked
Solution Approach 2:
The container transitions from a static rigid structure to a dynamic reconfigurable system. The wall elements can move between locked (assembled) and unlocked (disassembled) states, enabling the container to adapt its volume and configuration based on storage needs while maintaining strength when locked
2Quantity of substance
If larger containers are used for smaller goods, then storage capacity is sufficient, but accessibility and space efficiency deteriorate
Solution Approach 1:
The container can be segmented into smaller wall elements that can be removed or reconfigured to create access points. This allows users to easily access smaller goods stored in larger containers by disassembling specific sections rather than dealing with the entire rigid structure
Solution Approach 2:
The container configuration can dynamically change to provide access. Wall elements can be quickly unlocked and removed to create openings for accessing stored goods, then relocked after use, transforming the container from a sealed structure to an accessible one
3Strength
If traditional locking mechanisms are used, then structural integrity is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The locking mechanism is designed to automatically engage and disengage without manual intervention. When wall elements are brought into contact, the locking elements automatically lock them together, eliminating the need for complex manual locking operations while maintaining strong connections
Solution Approach 2:
Complex manual locking mechanisms are replaced with automatic snap-fit locking elements. The locking action is achieved through simple geometric interlocking and elastic deformation of the locking elements, eliminating the need for screws, bolts, or complex mechanical fasteners
4Strength
If manual locking steps are required, then structural integrity is ensured, but productivity and ease of operation are reduced
Solution Approach 1:
The locking mechanism performs the locking action automatically when wall elements are assembled. The locking elements engage themselves through simple contact and movement, eliminating manual locking steps and significantly speeding up assembly while maintaining strong connections
Solution Approach 2:
The locking elements are pre-configured in the wall elements to automatically engage when the walls are brought into contact. This preliminary positioning ensures that locking occurs automatically during the assembly process itself, without requiring separate manual locking operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism ensures reliable, tool-free assembly and disassembly, maintains structural integrity, and enhances space efficiency by allowing flexible configuration changes, facilitating easy access to the container's interior.
Implementation Method 1
a third element movably connected to the second element, the third element comprising at least one protruding locking element
Implementation Method 2
the at least one protruding locking element is configured to automatically engage behind the latch to lock the first element to the second element when moving the side wall elements from the unlocked to the locked state
