Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kick scooters lack a mechanism for smooth steering angle adjustment, resulting in inadequate control and maneuverability.
Innovation Solution
A steering angle adjustment mechanism comprising a positioning member, an internally threaded member, an adjustment screw, and compression springs, allowing users to adjust the steering angle by rotating the screw, which compresses or expands the spring to change the steering tube's angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional steering control mechanism is used, then the structure is simple, but the steering angle cannot be adjusted and steering smoothness is poor
Solution Approach 1:
The patent applies the dynamics principle by making the steering angle adjustable through a mechanism that allows the steering tube to rotate relative to the deck. The adjustment screw and compression spring create a dynamic system where the steering angle can be modified based on user needs, transforming a static steering mechanism into a dynamic one that adapts to different operating conditions.
Solution Approach 2:
The patent implements parameter changes by allowing the steering angle parameter to be adjusted. The adjustment screw changes the position of the steering tube, thereby changing the steering angle parameter. This enables the system to optimize steering performance for different speeds and conditions by modifying this key parameter.
2Adaptability or versatility
If a steering angle adjustment mechanism is added, then steering control is improved, but the device complexity increases
Solution Approach 1:
The patent applies the nested doll principle by integrating the adjustment mechanism components within the existing steering structure. The adjustment screw is positioned within the steering tube assembly, the compression spring is nested within the interconnecting member, and the bifurcation members are integrated into the link mechanism. This nesting approach allows the adjustment functionality to be incorporated without significantly increasing overall device complexity.
Solution Approach 2:
The patent implements universality by designing the adjustment mechanism to serve multiple functions. The adjustment screw not only adjusts the steering angle but also interacts with the compression spring to provide positioning stability. The bifurcation members serve both as connection elements and as guides for the adjustment mechanism. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
3Ease of operation
If the steering tube angle is fixed, then the structure is stable, but the maneuverability is limited
Solution Approach 1:
The patent applies dynamics by creating a steering system that can transition between fixed and adjustable states. The compression spring provides a stable positioning force that maintains structural stability during normal operation, while the adjustment screw enables dynamic modification of the steering angle when maneuverability is needed. This dynamic capability allows the system to optimize between stability and maneuverability based on operational requirements.
Solution Approach 2:
The patent implements parameter changes by allowing the steering angle parameter to be modified while maintaining structural integrity. The compression spring ensures that the steering tube remains stable at the adjusted angle by providing a restoring force, while the adjustment mechanism enables changes in the angle parameter. This combination of stability maintenance and parameter adjustability enhances both structural stability and maneuverability.
