Storage Container Hinge with Lateral Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage trunk designs with hinge mechanisms mounted between the top and back panels result in a weak pivotal interconnection, making them prone to damage during rough handling during loading and unloading.
Innovation Solution
A storage container design featuring a lateral beam across the back panel with hinge means fixed to three surfaces of the beam and the top panel, allowing the top panel to pivot securely and evenly, distributing the load across multiple edges to minimize wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hinge means are mounted between the top edge of the back panel and the back panel, then the top panel can pivot, but the pivotal interconnection is weak and prone to damage during rough handling
Solution Approach 1:
The hinge means are extended into a third dimension by adding a lateral beam that protrudes from the back panel. This creates a multi-dimensional mounting structure where the hinge is not merely mounted on the surface between the top panel and back panel, but extends laterally to engage with both panels more comprehensively, distributing stresses across multiple engagement points and significantly strengthening the pivotal interconnection.
Solution Approach 2:
The hinge assembly functions as a composite structural system combining the lateral beam, hinge plates, and mounting fixtures into an integrated unit. This composite structure distributes loads across multiple components rather than concentrating stress at a single mounting point, enhancing the overall reliability and resistance to damage during rough handling.
2Ease of manufacture
If hinge means are mounted on the back panel spaced from lateral beam, then installation is simple, but load distribution is poor causing increased wear
Solution Approach 1:
By extending the hinge means into the lateral dimension through the lateral beam, the structure transforms from a simple two-point mounting to a distributed multi-point engagement system. This dimensional extension naturally distributes the load across the width of the lateral beam and along its length, reducing wear at any single point while maintaining a relatively simple integrated construction.
Solution Approach 2:
The hinge means are segmented into multiple engagement points along the lateral beam, with the hinge plate distributed across different locations. This segmentation of the mounting function allows the load to be divided and distributed across multiple contact points, reducing stress concentration and extending the service life of the hinge connection.

AI summary
A storage container comprising a four-sided structure having a bottom panel and a pivotally mounted top panel. The container is provided with a lateral beam extending side-to-side across a back panel thereof. Hinge means are fixed to the back panel and extend along three surfaces of the lateral beam, and are fixed to the top panel, such that the top panel is pivotally mounted on the back panel and adapted to open and close with substantially simultaneous engagement on the four sides of the top panel with the four sides of the container.
