Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camping carts have complex folding mechanisms, leading to inconvenient use and storage, and often result in asynchronous folding, deformation, and reduced service life.
Innovation Solution
A foldable cart frame with a three-frame and two-cavity structure, featuring independently folding and unfolding first and second frames with respect to a middle frame, and a folding linkage mechanism for stable synchronous folding or unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cart frame is designed with multiple movable hinge points and complex folding mechanisms, then the cart can achieve folding functionality, but the structure becomes complicated and requires high matching accuracy
Solution Approach 1:
The cart frame is divided into multiple independent foldable assemblies, each consisting of a first frame, middle frame, and second frame connected by folding components. This segmentation allows each assembly to fold independently, simplifying the overall structure while maintaining folding functionality.
Solution Approach 2:
The first frame and second frame are designed to fold toward the middle frame, creating a nested configuration when folded. This nesting approach reduces the overall volume when folded and simplifies the structural arrangement compared to external folding mechanisms.
2Adaptability or versatility
If the support assembly and underframe assembly fold independently in different directions, then the folding mechanism is flexible, but asynchronous folding occurs requiring separate forces to be applied
Solution Approach 1:
The folding components connect the first frame, middle frame, and second frame in an integrated manner, allowing the entire assembly to fold synchronously as a unified structure. This merging of folding actions eliminates asynchronous folding and reduces the effort required, as users only need to apply force to one part of the assembly to initiate folding of the entire structure.
3Device complexity
If only one side of the underframe assembly is supported during folding, then the support structure is simple, but deformation occurs affecting service life
Solution Approach 1:
The folding components are positioned and configured to provide symmetrical support to both sides of the underframe assembly during the folding process. This balanced support distribution prevents deformation on either side, maintaining structural integrity and extending service life while keeping the support structure relatively simple.
4Volume of stationary object
If the cart is folded in a gathered manner, then storage space is reduced, but the body size cannot be adjusted according to usage conditions
Solution Approach 1:
The cart frame employs dynamically adjustable folding components that allow the first frame and second frame to be folded independently or simultaneously relative to the middle frame. This dynamic configuration enables the cart to transition between fully extended, partially folded, and fully folded states, providing size adjustability for different usage conditions while achieving compact storage when fully folded.

AI summary
Provided in the present application are an outdoor camping device, a camping cart, and a foldable cart frame. A foldable camping cart includes a first frame and a second frame, the first frame and the second frame being folded and unfolded by means of a folding mechanism, the folding mechanism being configured at a bottom of the camping cart to be adapted for load-bearing, where the folding mechanism includes: an upper folding member, which is operable to be folded upwards; a lower folding member, which is foldable upwards and is configured to support the upper folding member in a preset position in an unfolded state; and a linkage component configured to connect the upper folding member and the lower folding member to the first frame and to hold the upper folding member in the preset position in the unfolded state.
