Convertible Storage Box Cart Structure for Load Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carts for transporting storage boxes are bulky and inefficient, making it difficult for users to maneuver heavy loads.
Innovation Solution
A cart system that can be converted from a single layer to multiple layers using a storage box, featuring a base plate assembly, rotatable wheels, and a pull rod assembly that allows for adjustable configurations to accommodate different working conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cart is used to transport a storage box, then the transportation capability is improved, but the cart becomes bulky and difficult to maneuver
Solution Approach 1:
The cart is divided into separable components: a base plate assembly with walking assembly that can be detached from the storage box. This allows the cart to be segmented into a maneuverable base unit and a storage box unit, resolving the contradiction between transportation capability and ease of operation.
Solution Approach 2:
The cart structure transitions from a fixed single-layer design to a dynamic multi-layer configuration. The first support plate can be connected to or separated from the base plate, and the storage box can be mounted on either the base plate or the first support plate, enabling the cart to adapt its structure based on transportation needs.
2Adaptability or versatility
If the storage box is filled with tools and equipment, then the utility is improved, but the weight increases making it difficult to transport
Solution Approach 1:
The cart enables dynamic weight distribution by allowing the storage box to be mounted on different levels (base plate or first support plate). This creates multiple loading configurations that can be selected based on weight considerations, improving utility while managing transport weight.
Solution Approach 2:
The storage box serves multiple functions: it can be mounted on the base plate for heavy loads, on the first support plate for lighter loads, or used independently. The pull rod assembly also provides multiple functions for connecting and stabilizing the structure in different configurations.
3Device complexity
If the cart is designed with fixed single-layer structure, then the simplicity is maintained, but the adaptability to different working conditions is reduced
Solution Approach 1:
The cart structure is made dynamic rather than fixed. The first support plate can be connected to or separated from the base plate, and the storage box can be mounted on different levels, allowing the simple base structure to adapt to various working conditions without becoming overly complex.
Solution Approach 2:
The cart employs a nested configuration where the first support plate is positioned above the base plate, and the storage box can be mounted on either level. This nested arrangement allows for compact storage when not in use while providing expanded capacity when needed, maintaining simplicity while improving adaptability.

AI summary
A cart applicable to a storage box includes a walking assembly including rotatable wheels; a base plate assembly including a base plate, where the base plate is connected to the walking assembly, and the base plate assembly is at least partially disposed on the upper side of the walking assembly; a first support plate having at least a first state relative to the base plate, where when the first support plate is in the first state, the first support plate is connected to the base plate with an interval through at least one storage box.
