Traveling Apparatus with Speed-Linked Wheel Base Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal mobility vehicles with adjustable wheel base lengths require users to consecutively issue commands for extending or retracting the wheel base and changing speed, complicating driving operations.
Innovation Solution
A traveling apparatus with a mechanism that automatically adjusts wheel base length in conjunction with speed, allowing the user to control one parameter (speed or wheel base length) to automatically adjust the other, eliminating the need for separate commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wheel base length is extended to improve stability at high speed, then the vehicle requires additional control operations for wheel base adjustment, but this increases device complexity and ease of operation issues
Solution Approach 1:
The patent combines the wheel base adjustment function with the speed control function into a single integrated control system. The control unit automatically adjusts the wheel base length based on the detected speed, merging two separate control operations (wheel base adjustment and speed control) into one unified operation, thereby improving ease of operation while maintaining stability.
Solution Approach 2:
The vehicle system performs self-adjustment of the wheel base length based on speed detection. The control unit automatically determines the appropriate wheel base length according to the detected speed without requiring manual intervention from the user, allowing the system to serve itself and eliminate the need for additional control operations.
2Adaptability or versatility
If the vehicle provides adjustable wheel base lengths for different speeds, then it achieves better adaptability to different traveling conditions, but this increases device complexity
Solution Approach 1:
The control unit serves multiple functions: it detects the vehicle speed, determines the appropriate wheel base length based on the detected speed, and controls the wheel base adjustment mechanism. This multi-functional approach allows a single control system to handle both speed detection and wheel base adjustment, reducing overall device complexity while maintaining adaptability to different traveling conditions.
Solution Approach 2:
The system automatically changes the wheel base length parameter based on the speed parameter. The control unit detects speed and accordingly adjusts the wheel base length to an appropriate value, enabling the vehicle to adapt to different traveling conditions through parameter changes without requiring complex manual intervention or additional hardware.
3Ease of operation
If the vehicle automatically adjusts wheel base length based on speed, then it reduces driving operation complexity, but this requires sophisticated control mechanisms
Solution Approach 1:
The control system performs self-adjustment of the wheel base length based on speed detection. The control unit automatically determines the appropriate wheel base length according to the detected speed without requiring manual intervention from the user, allowing the system to serve itself and eliminate the need for additional control operations.
Solution Approach 2:
The system automatically changes the wheel base length parameter based on the speed parameter. The control unit detects speed and accordingly adjusts the wheel base length to an appropriate value, enabling the vehicle to adapt to different traveling conditions through parameter changes without requiring complex manual intervention or additional hardware.

AI summary
Provided is a traveling apparatus including at least, with respect to a traveling direction, a front wheel and a rear wheel and on which a user rides when travelling. The traveling apparatus includes a front wheel supporting member configured to rotatably support the front wheel, a rear wheel supporting member configured to rotatably support the rear wheel, an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheel by changing a relative position of the front wheel supporting member and the rear wheel supporting member, and a driving unit configured to drive at least one of the front wheel and rear wheel. The wheel base length adjusted by the adjusting mechanism is associated with a speed of the traveling apparatus achieved by driving the driving unit in such a way that the longer the wheel base length, the greater the speed becomes.
