Adjustable Steering Pivot Mechanism for Push Scooters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push scooters lack a mechanism to adjust the pivot angle of the steering bar, limiting user customization and control.
Innovation Solution
A pivot angle setting mechanism comprising a mount with parallel projections and sliding members, limit members, and spring-biased pins allows for adjustable steering bar angles by engaging and disengaging the sliding members with compression springs, enabling the steering bar to pivot between predetermined positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional push scooter uses a fixed steering bar mounting, then the structure is simple and reliable, but the pivot angle cannot be adjusted limiting user customization
Solution Approach 1:
The invention transforms the fixed steering bar mounting into a dynamic, adjustable system by introducing sliding members that can move along the mount between different limit members, allowing the pivot angle to be changed from fixed to variable while maintaining structural integrity
Solution Approach 2:
The mounting mechanism is divided into separate functional components: a stationary mount with openings, movable sliding members with grooves, limit members defining angular positions, and spring-biased pins for engagement. This segmentation allows independent adjustment of each component to achieve the desired pivot angle
2Adaptability or versatility
If sliding members with grooves and projections are used to enable angle adjustment, then pivot angle customization is achieved, but the mechanism becomes more complex with additional parts
Solution Approach 1:
The sliding member combines multiple functions into a single component: it provides the sliding motion for adjustment, contains the engagement grooves for the projections, and houses the spring-biased pin mechanism. This merging reduces the total number of separate parts while achieving the desired adjustability
3Reliability
If spring biased pins are used to secure the sliding members, then the pivot angle can be locked at selected positions, but the ease of operation is reduced due to the need to compress springs for adjustment
Solution Approach 1:
The spring-biased pin system is designed to automatically engage with the projections when the sliding member reaches a limit member position, locking the angle without requiring manual intervention. The spring provides the necessary force for both locking and releasing, making the system self-regulating
