Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cart devices lack a compact and efficient design for transporting objects, particularly for individuals with mobility impairments, as they often require cumbersome structures that are difficult to maneuver and store.
Innovation Solution
A collapsible cart design featuring a frame with pivotally coupled supports and a base that can be oriented perpendicular or collinear, allowing for easy folding and deployment, along with removably coupled boxes for object transport, facilitating easy storage and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing cart devices use a fixed rigid structure, then they provide stable support for transporting objects, but they become difficult to maneuver and store
Solution Approach 1:
The cart structure transitions from a fixed rigid configuration to a dynamic collapsible design where the base can rotate between a deployed position (perpendicular to frame) and a folded position (collinear with frame), and supports can extend or rest against the frame, allowing the cart to adapt its shape for both stable operation and compact storage
2Stability of the object's composition
If existing cart devices use a fixed rigid structure, then they provide stable support for transporting objects, but they occupy excessive storage space
Solution Approach 1:
The base rotates about a pivot to change orientation between perpendicular (deployed) and collinear (folded) positions relative to the frame, while supports pivot between extended and retracted positions, enabling the cart to collapse into a compact configuration that minimizes storage volume while maintaining structural stability during use
Solution Approach 2:
When folded, the base and supports are positioned to rest against and nest within the frame structure, creating a compact nested configuration that reduces the overall volume occupied during storage
3Stability of the object's composition
If existing cart devices use a fixed rigid structure, then they provide stable support for transporting objects, but they are difficult to store
Solution Approach 1:
The cart employs pivotally coupled supports and a rotatable base that enable easy transformation between deployed and folded states, making the cart simple to store by collapsing it into a compact form that fits into small spaces
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The collapsible cart provides a convenient and accessible means for transporting objects, such as groceries, by allowing for compact storage and easy deployment, specifically aiding physically disabled individuals in moving items between vehicles and homes.
Implementation Method 1
Each of the supports is pivotally coupled to the frame. Each of the supports is selectively positioned in a first position having each of the supports extending away from the frame. Each of the supports is selectively positioned in a second position having each of the supports resting against the frame. A base is pivotally coupled to the frame.

AI summary
A collapsible cart assembly includes a frame and a pair of supports. Each of the supports is pivotally coupled to the frame. Each of the supports is selectively positioned in a first position having each of the supports extending away from the frame. Each of the supports is selectively positioned in a second position having each of the supports resting against the frame. A base is pivotally coupled to the frame. The base is selectively positioned in a deployed position having the base being oriented perpendicular with respect to the frame. In this way the frame, supports and the base defines a cart. The base is selectively positioned in a folded position having the base being oriented collinear with the frame. A plurality of boxes is each of the boxes is removably coupled between the pair of supports. Each of the boxes may contain objects for transporting the objects in the cart.
