Pivoting Support Frame for Compact Transport Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for transporting people and goods lack flexibility and space-saving storage solutions, making them cumbersome to use and store.
Innovation Solution
A device with a pivotally connected support frame, telescopic guide rods, and adjustable roller elements allows for easy folding and storage, enabling quick deployment and compact storage, with a seat and footrest for comfort and stability, and a detachable luggage attachment for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the device is designed to be collapsible with pivotally connected support elements, then storage space is reduced, but the device complexity increases
Solution Approach 1:
The support frame is divided into multiple support elements (first support element, second support element) that can be pivotally connected and separated. This segmentation allows each element to be independently positioned or stored, reducing the overall storage volume when collapsed while maintaining structural integrity when assembled.
Solution Approach 2:
The support elements are designed to nest within each other when collapsed, with the second support element pivoting against the first support element. This nesting arrangement minimizes the storage volume by allowing components to occupy the same spatial envelope, while the pivotal connection maintains structural stability during use.
2Ease of operation
If the device allows quick folding and deployment, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The support elements are connected via pivotal joints that allow dynamic movement between extended (use) and collapsed (storage) positions. This dynamic connection enables quick folding and deployment without requiring complex locking or fastening mechanisms, as the pivotal joint naturally guides the motion while maintaining structural integrity.
3Adaptability or versatility
If the device accommodates both goods and a person, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The first support element is designed to serve dual functions: it can accommodate goods to be transported while also supporting the weight of a person on the second support element. This universal design allows a single device structure to perform multiple functions (goods transport and person transport) without requiring separate specialized components, thereby improving adaptability while controlling complexity.

AI summary
The device has a set of supporting elements (1, 2), where one of the supporting elements is swingable and definably arranged on the other supporting element over a holding structure (7). The former supporting element includes rolling elements (20, 22) and foot rest (10), and the latter supporting element includes rollers (24, 25) and a base pipe. A telescopic-shaped guide bar (4) is provided in the base pipe, and another telescopic-shaped guide bar (5) is detachably fixed in the former telescopic-shaped guide bar. The guide bars include a handle grip (12) and a release unit (13), respectively.
