Lid Dolly with Casters for Storage Container Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage containers lack a convenient and secure method for transporting multiple heavy containers, as they often require the use of transport dollies which may not be readily available, and stacking containers without proper securing can be unstable.
Innovation Solution
A storage device with a container and a lid dolly that includes a main portion with casters and stabilizers, allowing the container to be securely positioned on the lid dolly for easy movement, and a kit to convert existing storage container lids into dolly features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transport dollies are used to move multiple storage containers, then the containers can be transported, but the dollies may not be readily available and require additional securing equipment
Solution Approach 1:
The patent combines the transport dolly functionality directly with the storage container lid. The lid is converted into a self-contained dolly system by attaching casters to its underside, eliminating the need for separate transport dollies and securing equipment. This merging of functions allows the container itself to serve as its own transport platform.
Solution Approach 2:
The lid is designed to perform multiple functions: it serves as both the closure for the storage container and as the base for the transport dolly system. The raised peripheral portion of the lid engages with the container rim to secure it, while the underside provides mounting surfaces for casters and stabilizers, creating a multi-functional component.
2Productivity
If storage containers are stacked for transport, then space is optimized, but the containers may slip or fall without proper securing
Solution Approach 1:
The lid dolly system is prepared in advance by pre-attaching casters and stabilizers to the lid underside before the container needs to be transported. The raised peripheral portion is designed to engage with the container rim, creating a pre-configured securing mechanism that automatically stabilizes the container when placed on the dolly platform.
Solution Approach 2:
The lid dolly acts as an intermediary between the container and the transport surface. The stabilizers extend downward to contact the ground or support surface, while the raised peripheral portion contacts the container rim, creating an intermediate securing structure that prevents slipping and falling during transport.
3Ease of operation
If the lid is converted into a dolly with casters and stabilizers, then the container becomes movable and stable, but the lid structure must be reinforced
Solution Approach 1:
The lid dolly system is divided into distinct functional segments: the raised peripheral portion for container engagement, the main lid surface for caster mounting, and the underside area for stabilizer attachment. This segmentation allows the reinforcement to be focused specifically on the areas where structural loads are applied, rather than strengthening the entire lid uniformly.

AI summary
A storage device has a container and a lid dolly that is usable as a lid to close the container and as a dolly to transport the container, wherein the lid dolly has casters configured to fit within the interior of the container when the lid dolly is closed on the container. A storage device kit has a container, a lid, a template, casters and fasteners. A retrofit kit for a storage device with a container and a lid has a template, casters and fasteners. The template may be installed as a reinforcement plate to structurally reinforce the lid for supporting the weight load of the container and its contents.
