Three-Ski Trike Folding Frame for Compact Cable-Car Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ski winter sports devices, such as ski bikes, require significant space and volume for transport, limiting the number of users that can be accommodated in cable cars, particularly in high-capacity ski areas.
Innovation Solution
A ski trike design with three arrangeable skis that can be folded to reduce overall length and height, allowing for compact transport and efficient use of space, featuring a frame and standing device connected in a movable manner to facilitate folding and unfolding without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ski winter sports device is designed with a fixed frame structure for stable operation, then operational stability is improved, but transport volume increases and more space is required in cable cars
Solution Approach 1:
The frame device is divided into multiple frame parts that can be moved relative to each other. The first frame part connects to the holding device, the second frame part connects to the standing device, and these parts can be folded together to reduce volume while maintaining structural integrity during operation.
Solution Approach 2:
The frame device transitions from a static fixed structure to a dynamic foldable structure. The frame parts are connected in a relatively movable manner, allowing the device to adapt its volume - expanded during operation for stability and compacted during transport to reduce space requirements.
2Volume of moving object
If the ski winter sports device is designed with a foldable frame structure to reduce transport volume, then transport efficiency is improved, but device complexity increases
Solution Approach 1:
The frame is segmented into multiple movable parts that can be folded together. This segmentation enables volume reduction while keeping each individual frame part relatively simple in structure, avoiding the need for complex mechanisms.
Solution Approach 2:
The frame employs simple movable connections between frame parts that allow folding and unfolding without requiring complex locking mechanisms or additional components, thus reducing device complexity while achieving the foldable function.
3Reliability
If the frame device and standing device are connected rigidly for stable operation, then operational stability is improved, but the ability to fold and reduce volume is worsened
Solution Approach 1:
The connection between the frame device and standing device is designed to be relatively movable rather than rigid. This allows the structure to maintain stability during operation when the parts are extended, while enabling folding and volume reduction when the parts are moved relative to each other.
Solution Approach 2:
The frame and standing device are divided into separate frame parts that can move relative to one another. This segmentation provides the flexibility needed for folding while maintaining structural integrity and operational stability when the device is in use.
