Hinged Lid Security Recess and Moisture Lip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable storage containers lack effective tamper-resistant features, allowing unauthorized access and moisture intrusion, as they can be disassembled and permit seepage between lid halves.
Innovation Solution
The storage container design includes hingeably connected lid halves with security tabs and recesses to prevent vertical movement, a lip to prevent moisture seepage, and a pocket for identification tickets, along with features enhancing stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hinged connection of lid halves to side walls is made disassemblable for ease of operation, then the ease of operation is improved, but the security against unauthorized access deteriorates
Solution Approach 1:
The hinge pin is designed with a head that must be inserted into the hinge receiver in a specific orientation before the lid can be attached. This preliminary action of proper alignment prevents unauthorized disassembly while allowing legitimate users to operate the container by following the correct insertion procedure.
Solution Approach 2:
The hinge pin acts as an intermediary element between the lid and the container body. Its specific design with a head that fits into the hinge receiver creates a secure connection that is difficult to disassemble without proper tools or knowledge, thus maintaining security while still allowing operation.
2Device complexity
If the lid halves are connected without additional security features, then the device complexity is reduced, but the security against tampering deteriorates
Solution Approach 1:
The hinge connection is segmented into distinct components: a hinge pin with a head, a hinge receiver with specific internal geometry, and positioning features. This segmentation allows each component to contribute to security while maintaining simplicity in the overall design. The head on the hinge pin prevents removal without proper access, adding security without complex mechanisms.
3Ease of operation
If the lid halves are allowed to move freely on hinges, then the ease of operation is improved, but the security against vertical movement and unauthorized access deteriorates
Solution Approach 1:
The hinge connection has different qualities at different locations: the head on the hinge pin provides localized security against vertical movement and removal, while the body of the hinge allows free rotation for operation. This local differentiation of properties maintains both security and ease of operation.

AI summary
A storage container includes a base having side walls and end walls extending upwardly from the base. Lid halves are hingeably connected to upper edges of the side walls. A security recess is formed in the side walls adjacent to each hinge and corresponds with a security tab projecting from the lid halves preventing vertical movement of the outer edge of the lid half when the lid is in the closed position. The lid halves also include a lip adjacent to the hinge and upper and lower leaves that overlap with the opposing lid half to prevent moisture from seeping into the storage container.
