Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable motorized vehicles have complex frame structures that complicate folding and unfolding, making them cumbersome and time-consuming, and there is a need for a more compact, lightweight, and easy-to-carry design that is both strong and convenient to use.
Innovation Solution
A novel frame connecting mechanism using pairs of slide rails and connecting members with sliding blocks and fixture blocks, along with a frame locking mechanism involving a handle, cable tube, and compression spring, allows for easy folding and unfolding by forming a slidable connection between the frame components and enabling secure locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional foldable frame structure is used, then the vehicle can be folded and unfolded, but the structure becomes complex and the folding/unfolding process becomes complicated and slow
Solution Approach 1:
The frame is divided into multiple modular components including first slide rails, second slide rails, first connecting members, and second connecting members. Each component has a specific function and can be independently manufactured and assembled, simplifying the overall structure while enabling foldable functionality.
Solution Approach 2:
The frame employs dynamic slide rail mechanisms that allow smooth transitions between folded and unfolded states. The slide rails with connecting members create movable joints that guide the folding motion, making the operation convenient and controlled rather than rigid and complex.
2Weight of moving object
If the frame is designed to be compact and lightweight, then it becomes easier to carry, but the structural strength may be compromised
Solution Approach 1:
The frame utilizes composite construction combining aluminum alloy materials that provide high strength-to-weight ratio. The slide rails and connecting members are made from lightweight yet durable materials that maintain structural integrity while reducing overall vehicle weight for easier portability.
Solution Approach 2:
By segmenting the frame into multiple connected components rather than a single monolithic structure, the design achieves both weight reduction and strength distribution. The modular components can be optimized individually for weight while the collective assembly maintains overall structural strength through the connecting members.
3Volume of moving object
If the frame is designed to be compact when folded, then storage space is reduced, but the folding mechanism becomes more complex
Solution Approach 1:
The frame components are designed to nest within each other when folded, with the second slide rails inserting into the first slide rails, and connecting members stacking in a nested configuration. This nesting arrangement achieves compact folded volume without requiring complex mechanical folding mechanisms.
Solution Approach 2:
The dynamic slide rail system allows the frame to transition smoothly between extended and compact nested positions. The connecting members guide the motion to ensure proper alignment during folding, achieving compact storage size through controlled dynamic movement rather than complex static mechanisms.
4Ease of operation
If the frame allows easy folding and unfolding, then operational convenience is improved, but the time required for folding and unfolding increases
Solution Approach 1:
The frame components are pre-configured with aligned slide rails and connecting members that guide the folding motion along predetermined paths. The locking mechanisms are pre-positioned to engage automatically at specific points during folding, eliminating the need for manual alignment steps and reducing the time required for folding and unfolding operations.
Solution Approach 2:
The dynamic slide rail mechanism enables smooth, continuous motion during folding and unfolding without jerky movements or manual intervention. The connected components move in coordinated fashion along the slide rails, maintaining alignment throughout the transformation process and reducing the total time needed for complete folding or unfolding.

AI summary
A foldable motorized vehicle includes a frame connecting mechanism and a frame locking mechanism. The frame connecting mechanism comprises: a pair of first slide rails, a pair of second slide rails, a pair of first connecting members, and a pair of second connecting members. The front end portions of the first slide rails are fixedly connected to a front frame, the rear end portion of the second slide rails are fixedly connected to a rear frame. The front end portions of the second slide rails are supported on the rear end portions of the first slide rails, creating a slidable connection between the first slide rails and the second slide rails with the first connecting members and the second connecting members. The frame locking mechanism comprises a handle, a cable tube, a cable, a mounting base, a compression spring, and a stopper.
