Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a folding vehicle frame is designed to be compact for storage in small spaces, then storage convenience is improved, but the frame strength and stability during operation deteriorate
Solution Approach 1:
The frame is divided into multiple telescopic tube sections that can slide relative to each other. The frame includes a first telescopic tube with a first section and a second section, and a second telescopic tube with a third section and a fourth section. This segmentation allows the frame to achieve compact dimensions when folded while maintaining structural integrity when extended for operation.
Solution Approach 2:
The frame employs dynamic telescopic mechanisms with movable connections between tube sections. The first and second telescopic tubes can extend and retract, transforming the frame from a compact folded state to an expanded operational state. This dynamic structure enables the frame to adapt its dimensions while maintaining strength through proper mechanical engagement of the telescopic sections.
2Ease of manufacture
If the frame structure is simplified to reduce manufacturing complexity, then manufacturing cost is reduced, but the folding mechanism reliability deteriorates
Solution Approach 1:
The folding mechanism is segmented into modular components including first and second telescopic tubes with distinct first and second sections each. This modular segmentation allows for standardized manufacturing of individual sections while ensuring reliable assembly through consistent connection interfaces between sections.
Solution Approach 2:
The telescopic tubes incorporate dynamic connection mechanisms that allow controlled movement between sections. These mechanisms include movable connections with positioning features that ensure reliable engagement and disengagement, maintaining folding mechanism reliability while enabling smooth extension and retraction operations.
3Strength
If the frame is designed with multiple telescopic sections to maintain strength when folded, then frame strength is improved, but the device complexity increases
Solution Approach 1:
The frame structure is divided into segmented telescopic tubes with standardized sections. The first telescopic tube contains a first section and a second section, while the second telescopic tube contains a third section and a fourth section. This segmentation maintains strength through proper distribution of structural elements while managing complexity through modular design principles.
Solution Approach 2:
The dynamic telescopic mechanism allows the frame to transition between folded and extended states while maintaining strength. The movable connections between sections include positioning features and engagement mechanisms that ensure structural integrity during operation, balancing the need for strength with acceptable device complexity.

AI summary
Disclosed is a folding vehicle frame (100), comprising a front vehicle frame (110), a rear vehicle frame (120) and a folding seat support frame (8). The front vehicle frame (110) and the rear vehicle frame (120) are pivotally connected. The folding seat support frame (8) comprises a linkage rod (81) and a frame body, wherein a front end of the linkage rod (81) is connected with the front vehicle frame (110), a rear end of the linkage rod (81) is pivotally connected with the frame body, and the linkage rod (81) is able to swing as the front vehicle frame (110) collapses and thus drives the frame body so that same collapses. The folding vehicle frame (100) has the advantages of quick and convenient collapsing.
