Storage Container Door Lid with Multi-Directional Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotation-type storage containers with fixed rotation shafts hinder access to the take-out port when the door type lid is opened, as it obstructs the path, limiting access directions.
Innovation Solution
A storage container design featuring a door type lid with a detachable coupling mechanism that allows rotation in various directions by attaching to multiple coupling counterpart portions on the outer peripheral frame, enabling flexible opening and closing directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed rotation shaft is used for the door type lid, then the opening and closing mechanism is simple and reliable, but the door type lid can only open in one direction and may obstruct access to the take-out port
Solution Approach 1:
The outer peripheral frame is segmented into multiple coupling counterpart portions positioned at different locations and orientations. The door type lid is divided into a lid body and a separate coupling portion, allowing the coupling portion to be selectively attached to different coupling counterpart portions. This segmentation enables the door type lid to open in multiple directions while maintaining a relatively simple overall structure.
Solution Approach 2:
The coupling portion and coupling counterpart portions are designed to enable detachable and reattachable connections. The coupling mechanism allows the door type lid to dynamically change its opening direction by detaching from one coupling counterpart portion and attaching to another, transforming a static fixed-rotation system into a dynamic multi-directional system.
2Ease of operation
If the rotation shaft is positioned to allow easy access to the take-out port, then access is improved, but the door type lid may get in the way when accessed from certain directions
Solution Approach 1:
The coupling mechanism is designed with multiple coupling counterpart portions positioned at different locations on the outer peripheral frame. This universal coupling system allows the door type lid to be configured for optimal access from any direction, making the storage container adaptable to different installation locations and user needs. The same coupling mechanism serves multiple functions: securing the lid, enabling rotation, and allowing direction changes.
3Adaptability or versatility
If the door type lid is designed to open in a fixed direction, then the structure is simple, but it cannot adapt to different installation spaces and access requirements
Solution Approach 1:
The coupling counterpart portions are positioned at specific locations and orientations on the outer peripheral frame, each optimized for a particular opening direction. The coupling portion on the door type lid is designed with local features that match these specific coupling counterparts. This local quality optimization allows the system to adapt to different installation spaces while keeping the coupling structure itself relatively simple and standardized.

AI summary
Provided is a storage container having a door lid whose opening and closing direction is changeable, and in which a take-out port can be accessed from various directions. The storage container includes a container body and the door lid. The container body has an outer peripheral frame defining the take-out port. The door lid can be attached to the outer peripheral frame, and opens and closes the take-out port. The outer peripheral frame includes plural coupling counterpart portions extending in directions in which the outer peripheral frame extends. The door lid includes a coupling portion detachably coupled to any of the coupling counterpart portions. The coupling portion and the coupling counterpart portions are configured such that, when the coupling portion is coupled to any of the coupling counterpart portions, the door lid can be rotated with respect to the outer peripheral frame to open and close the take-out port.
