Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-wheeled means of transport, such as tricycles and folding scooters, have limited flexibility in adjusting the track width and center of gravity, which restricts their versatility and maneuverability.
Innovation Solution
A three-wheeled transport system with a frame that has adjustable frame legs and a connection mechanism allowing for telescopic extension, enabling the adaptation of track width and center of gravity adjustment, combined with a pedal drive or internal combustion engine for driving, and modular components for varying configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the track width of three-wheeled means of transport is fixed or limited to fixed widths, then the structural simplicity is maintained, but the adaptability to different requirements is reduced
Solution Approach 1:
The frame legs are designed to be movable relative to each other through a joint connection, allowing the track width to be dynamically adjusted between wide and narrow positions. This dynamic structure enables the means of transport to adapt to different operational requirements while maintaining a relatively simple overall frame design.
Solution Approach 2:
The connection between frame legs is designed to be lockable, allowing the track width parameter to be changed between discrete fixed positions. This enables the system to provide variable track width without requiring a completely complex continuous adjustment mechanism, balancing adaptability with structural simplicity.
2Adaptability or versatility
If the frame legs are made fixed, then the manufacturing simplicity is maintained, but the ability to adjust center of gravity and track width is limited
Solution Approach 1:
The frame is segmented into multiple frame legs that can move independently relative to each other. This segmentation allows the center of gravity to be adjusted by changing the position of individual frame legs, while each leg remains a relatively simple component that is easy to manufacture.
Solution Approach 2:
The frame legs are designed with movable joints that allow dynamic adjustment of the frame geometry. This enables center of gravity adjustment and track width variation without requiring complex fixed structures, maintaining ease of manufacture while providing adaptability.
3Ease of operation
If the wheel position is fixed, then the structural simplicity is maintained, but the maneuverability and stability adaptation is reduced
Solution Approach 1:
The wheel positions are made dynamic through movable frame legs connected by joints. This allows the wheel base to be adjusted between wide (for stability) and narrow (for maneuverability) configurations, enabling the operator to adapt the means of transport to different operational conditions without adding complex positioning mechanisms.
