Steering Handle Height Adjustment for Personal Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal mobility devices, such as electric bicycles and scooters, often have fixed steering handle heights, which can be inconvenient for users with varying physical conditions, particularly those who are taller or shorter than the average user.
Innovation Solution
A personal mobility device equipped with a height adjustment mechanism, including a lifting driving device and an image sensor or wireless communication module, that adjusts the steering handle height based on user body information to accommodate individual physical conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the steering handle height is fixed for average users, then the device structure is simple, but it becomes inconvenient for users with different physical conditions
Solution Approach 1:
The patent implements a height adjustment mechanism that allows the steering handle to change its vertical position dynamically. The lifting driving device enables the upper steering shaft to ascend and descend, transforming the fixed handle into an adjustable one that adapts to different user heights, thereby resolving the contradiction between operational convenience and device complexity
Solution Approach 2:
The patent changes the vertical position parameter of the steering handle through a lifting mechanism. By adjusting the height parameter of the upper steering shaft relative to the lower steering shaft, the system accommodates users with different physical conditions while maintaining a relatively simple overall structure
2Adaptability or versatility
If automatic height adjustment based on body information is implemented, then usability for wider range of users is enhanced, but device complexity and cost increase
Solution Approach 1:
The patent implements an automatic height adjustment system where the image sensor captures user body information, the controller processes this data to determine appropriate handle height, and the lifting driving device automatically adjusts the steering handle position. This self-service system enhances adaptability without requiring manual intervention from the user
Solution Approach 2:
The patent integrates multiple functions into a unified system: the image sensor serves both authentication and body measurement purposes, the controller manages both user verification and height adjustment, and the lifting mechanism provides automatic adaptation. This multi-functionality approach enhances versatility while controlling overall system complexity
