Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible carts lack efficient mechanisms for transitioning between expanded and collapsed positions, stability during use, and integration of motorized functionality, limiting their convenience and versatility.
Innovation Solution
A collapsible cart design featuring rotatable walls, slidable members, and a motorized option with steerable wheel assemblies, allowing for easy conversion between expanded and collapsed states, enhanced stability, and the ability to transport heavy loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a collapsible cart is designed to fold for storage, then storage convenience is improved, but structural complexity increases
Solution Approach 1:
The cart structure is divided into multiple collapsible sections with rotatable walls and slidable members that can be independently folded. Each section contains panels connected by hinges and locking mechanisms, allowing the cart to be segmented into compact segments for storage while maintaining structural integrity during use.
Solution Approach 2:
The cart employs dynamic elements including rotatable walls that can pivot between extended and retracted positions, slidable members that move along tracks to lock and unlock panels, and collapsible sections that transition between stable operational states and compact storage states, enabling easy transformation between use and storage configurations.
2Power
If a motorized system is added to the cart, then load handling capability is improved, but device complexity increases
Solution Approach 1:
The motorized system is integrated with the existing collapsible cart structure by combining the motor assembly with the wheel assembly. The motor is mounted on the cart frame and directly drives the wheels through a transmission mechanism, merging the propulsion function with the mobility system to handle heavy loads while maintaining the collapsible cart's portability and storage capabilities.
3Stability of the object's composition
If the cart includes multiple locking mechanisms for stability, then stability during use is improved, but ease of operation decreases
Solution Approach 1:
The locking mechanisms are designed to automatically engage and disengage based on the cart's operational state. When the cart is in use, the locking mechanisms self-activate to secure the rotatable walls and slidable members in stable positions. When collapsing or storing, the mechanisms automatically release without requiring manual intervention, providing stable locking during operation while simplifying the user operation sequence.

AI summary
A collapsible cart configured to convert from a collapsed position to an expanded position, the cart having opposing side walls and a bottom wall, and, in the expanded position, forming one or more open compartments which may be enclosed by a cover comprising one or more panels. The side walls may include one or more pairs of panels rotatably together connected at joints such that distal edges of each pair of panels are rotatable inwardly toward each other and a collapsed position or outwardly away from each other toward an expanded position. Also, disclosed is a motorized collapsible cart.
