Hinged Lid Access for Stacked Storage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stacked plastic transport and storage containers require rearrangement of top containers to access goods from lower containers, making it inconvenient for removing items without compromising the security of the contents.
Innovation Solution
A plastic transport and storage container design featuring a bottom part with four sidewalls, where at least one sidewall has a removable opening covered by a hinged lid with retention mechanisms, allowing access only from inside, enabling easy removal of goods without rearranging stacked containers and ensuring security during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If containers are stacked for storage, then storage space utilization is improved, but access to goods in lower containers requires rearranging top containers
Solution Approach 1:
The container is divided into separate functional components: a body for stacking and a removable lid for access. The lid can be detached independently from the body, allowing access to goods in lower containers without moving stacked containers. This segmentation resolves the contradiction by separating the stacking function (body) from the access function (lid).
Solution Approach 2:
The removable lid acts as an intermediary element between the stacked container configuration and the need for access. By removing the lid, the container body maintains its stacking capability while the lid is set aside, enabling access to goods below without disturbing the stacked arrangement. The lid serves as the mediator that allows both stacking and access functions to coexist.
2Reliability
If containers are made secure with lids and seals, then security is improved, but ease of access for legitimate users deteriorates
Solution Approach 1:
The lid transitions from a static sealed state during transport to a removable state during storage and access. The lid can be dynamically removed by users with authorization while maintaining security during transport. This dynamic behavior resolves the contradiction by allowing the container to adapt its security level based on the operational context.
Solution Approach 2:
The lid and seal mechanism provides localized security only where needed (at the opening), while the rest of the container body remains simple and accessible. The security feature is concentrated in the lid assembly rather than requiring complex security mechanisms throughout the entire container, maintaining ease of access for legitimate users while ensuring security during transport.

AI summary
The invention relates to a plastic storage and transport container. The container includes a bottom part and four sidewalls fixedly disposed on the container bottom, or hinged tiltably and latchable to one another. The storage and transport container includes a removal opening (2) in at least one sidewall (1) which is closeable by way of a lid (3). Preferably, the lid (3) is of two-part construction made up of two lid elements (3a, 3b), wherein the two lid elements (3a, 3b) are swingably connected together by way of a hinge-like connection. This lid (3) can only be opened from the inside of the container. When the container is transported, the lid (3) is closed and cannot be opened or manipulated from the outside. For storage, the containers are stacked in such a way that a removal opening (2) of each container is accessible from the front. Prior to stacking the containers, the lids (3) are partially or entirely opened so that the goods located in the container can be removed from the container.
