Chest With Independent Secondary Lid for Stacked Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable storage container systems face challenges in providing quick and efficient access to the interior of stacked containers while maintaining secure stacking and mobility.
Innovation Solution
A chest with a main lid and a secondary lid system, featuring pivotable lids and latches that allow selective access to the interior without fully opening the main lid, and secure attachment of additional containers using pivotable latches and buckles for easy stacking and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a main lid is used to cover the interior storage volume, then security and protection are improved, but access time and convenience deteriorate
Solution Approach 1:
The lid system is divided into two independent segments: a main lid for security and a secondary lid for quick access. The secondary lid can be opened independently without moving the main lid, allowing rapid access to frequently used items while the main lid remains closed to maintain security and protection of the storage volume.
2Productivity
If containers are stacked for joint movement, then mobility and space utilization are improved, but access to stacked containers deteriorates
Solution Approach 1:
The container system is segmented into a base container and removable stackable containers. The secondary lid on the base container can be opened independently to access items in the base container even when other containers are stacked on top, eliminating the need to move or unstack containers for access.
Solution Approach 2:
The secondary lid acts as an intermediary access point between the stacked container system and the interior storage volume. It provides a direct access pathway that bypasses the need to move stacked containers, while the main lid and stacking mechanism maintain the overall structural integrity and mobility of the system.
3Ease of operation
If a secondary lid is added for quick access, then access convenience is improved, but device complexity increases
Solution Approach 1:
The lid system is divided into two independent segments: a main lid for security and a secondary lid for quick access. The secondary lid can be opened independently without moving the main lid, allowing rapid access to frequently used items while the main lid remains closed to maintain security and protection of the storage volume.
Solution Approach 2:
The secondary lid serves multiple functions: it provides quick access to frequently used items, maintains the security of the main storage volume by leaving the main lid closed, and allows the container to remain part of a stacked configuration. This multi-functionality justifies the added complexity by delivering significant operational benefits.
4Reliability
If latches are added to secure the secondary lid, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The secondary lid latch is designed as a self-service mechanism that automatically engages when the secondary lid is closed and can be easily released by the user. The latch works independently of the main lid latch system, allowing users to secure or open the secondary lid without requiring assistance or complex operations, thereby maintaining ease of operation while providing security.

AI summary
A stackable storage system is disclosed. The system includes a base storage container disposed on a wheeled cart, and one or more additional storage containers removably secured on top of the base container. A main lid is disposed on the storage container and is pivotable between a position in which it covers at least a portion of the interior storage volume and a position in which it does not cover the interior storage volume. The main lid has a main lid opening formed therethrough. A secondary lid is pivotable between a position in which it covers the opening and a second position in which it does not cover the opening to allow access to the interior storage volume via the opening while the main lid covers the interior storage volume.
