Rolling Drawer Storage Container With Auto-Deploy Wheels and Braking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rolling storage units require manual unstacking of trays or objects to access drawers, limiting mobility and ease of access to stored items.
Innovation Solution
A modular storage system with a rolling drawer featuring integrated wheels that deploy automatically or manually, allowing the drawer to extend without unstacking, and a braking system to stabilize the unit during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drawer is made extendable for easier access to stored items, then ease of operation is improved, but device complexity increases due to integrated wheel deployment mechanisms
Solution Approach 1:
The patent combines the drawer extension mechanism with the wheel deployment mechanism into a single integrated system. When the drawer is pulled out, it automatically triggers the deployment of front wheels through a mechanical linkage, eliminating the need for separate controls and reducing operational steps while maintaining functionality.
Solution Approach 2:
The front wheels are pre-positioned within wheel housings that are integrated into the drawer structure. The mechanical linkage is pre-configured so that drawer movement automatically actuates wheel deployment without requiring additional user actions, preparing the system in advance for mobility needs.
2Ease of operation
If wheels are integrated into the drawer for mobility, then ease of operation is improved, but reliability decreases due to potential instability during extension
Solution Approach 1:
The system transitions from a static configuration to a dynamic one based on operational needs. When the drawer is retracted, the unit remains stable with wheels stored inside. When the drawer is extended, the mechanical linkage automatically deploys the front wheels, transforming the unit into a mobile configuration that adapts to the user's needs.
Solution Approach 2:
A mechanical linkage acts as an intermediary between the drawer extension and wheel deployment. This intermediary mechanism ensures that wheel deployment is synchronized with drawer extension, providing controlled and stable transitions between stationary and mobile states while maintaining structural integrity.
3Device complexity
If manual wheel deployment is used to reduce complexity, then device complexity is reduced, but productivity decreases due to additional manual steps
Solution Approach 1:
The system performs wheel deployment automatically through the mechanical linkage connected to the drawer. When the user pulls out the drawer, the linkage self-actuates to deploy the front wheels without requiring the user to manually operate separate wheel controls, making the system serve itself and eliminating redundant manual steps.
