Three-Frame, Two-Cavity Foldable Cart Frame for Adjustable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camping carts are cumbersome due to complicated folding mechanisms and lack the ability to adjust their body size to suit different usage scenarios, making them inconvenient to use and store.
Innovation Solution
A foldable cart frame with a three-frame and two-cavity structure, featuring independently foldable and unfoldable first and second storage cavities, allowing adjustment to fully-opened, half-opened, or fully-collapsed states, and equipped with a folding linkage mechanism and locking apparatus for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camping cart uses a gathered folding manner, then the structure is simple and easy to store, but the body size cannot be adjusted according to usage conditions
Solution Approach 1:
The cart frame is divided into multiple independent folding sections (first folding component and second folding component) that can be folded and unfolded independently. This segmentation allows the cart body to be adjusted to different sizes (fully-opened, half-opened, or fully-collapsed) while maintaining relatively simple folding mechanisms in each section.
Solution Approach 2:
The cart frame employs dynamic folding components with hinge connections that enable smooth transitions between different configuration states. The folding components include hinge plates and hinge pins that allow the frame sections to move flexibly between folded and unfolded positions, providing adaptability without excessive complexity.
2Ease of operation
If the camping cart is designed to be foldable, then it is easier to store and transport, but the stability in each state becomes difficult to ensure
Solution Approach 1:
The folding components feature asymmetric hinge plate and hinge pin configurations that provide natural stopping positions and stable locking in specific orientations. The asymmetric design ensures that when the cart is folded or unfolded to a particular state, the structural elements naturally settle into stable positions that maintain reliability.
Solution Approach 2:
The hinge connections and folding components are pre-designed with built-in stabilization features that automatically engage when the cart is folded or unfolded. The hinge structures include preliminary positioning elements that ensure stability is established as part of the folding process itself, rather than requiring additional stabilization steps.
3Adaptability or versatility
If the camping cart uses a simple frame structure, then the assembly and disassembly is easy, but the functionality to support various usage scenarios is limited
Solution Approach 1:
The cart frame is designed as a universal structure that can support multiple usage scenarios through its configurable folding capabilities. The same basic frame structure with hinge connections can accommodate fully-opened configurations for maximum functionality, half-opened configurations for partial use, or fully-collapsed configurations for storage, making the structure adaptable to various needs without requiring multiple specialized designs.

AI summary
Provided in the present invention are an outdoor camping device, a camping cart, and a foldable cart frame. A foldable cart frame is applied to a portable carrying cart, and includes a first frame and a second frame arranged in a length direction, where the foldable cart frame further includes a middle frame arranged between the first frame and the second frame, where the first frame and the middle frame are connected by a first folding component to enable the first frame to be folded and unfolded with respect to the middle frame, and a first storage cavity is formed between the first frame and the middle frame when unfolded; and where the second frame and the middle frame are connected by a second folding component to enable the second frame to be folded and unfolded with respect to the middle frame, and a second storage cavity is formed between the second frame and the middle frame when unfolded. The present invention has beneficial effects of novel design, the capacity to adjust a body of a camping cart to a fully-opened state, a half-opened state, or a fully-collapsed state as needed, and being easy to carry.
