Transformable Transport Cart With Single-Action Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport carts are difficult to handle and transform between different operating modes efficiently.
Innovation Solution
A transport cart with a base assembly, side assemblies, wheels, and receptacles, equipped with an actuating device that allows seamless transitions between packing, pulling, and pushing modes through a single-direction actuation of an actuating element, coupled with the movement of wheels and receptacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transport cart uses traditional transformation mechanisms between operating modes, then the structural stability is maintained, but the ease of operation deteriorates due to complex handling requirements
Solution Approach 1:
The patent combines multiple transformation functions into a single actuating element. By merging the actuation of side assemblies and wheel assemblies into one unified mechanism, the user can transform between operating modes with a single action, significantly improving ease of operation while maintaining structural stability through the integrated design
2Volume of moving object
If the transport cart is designed for compact storage, then the space utilization is improved, but the ease of operation worsens due to difficulty in transformation
Solution Approach 1:
The patent employs dynamic transformation mechanisms that allow the transport cart to transition smoothly between compact storage configuration and expanded operating modes. The side assemblies and wheel assemblies are designed with movable connections that enable easy folding and unfolding, making compact storage achievable without compromising transformation ease
3Adaptability or versatility
If the transport cart uses multiple actuation directions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The single actuating element is designed with universal functionality to perform multiple transformation tasks. It can actuate both side assemblies and wheel assemblies through different movement paths, enabling the transport cart to achieve multiple operating modes (packing mode, first operating mode, second operating mode) without requiring separate actuators for each function

AI summary
A transport cart having a base assembly, having two opposing side assemblies arranged on the base assembly, having a respective wheel arranged on a respective one of the side assemblies, and having at least one receptacle arranged between the side assemblies for a respective transport box. The transport cart is transferable between a packing mode and a first operating mode or between the first operating mode and a second operating mode. A method for transferring such a transport cart between the first operating mode and the second operating mode, a method for transferring such a transport cart between the packing mode and the first operating mode, and a method for transforming such a transport cart are also disclosed.
