Kickstand Mount with Fore-Aft Torque Distribution for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kickstands for bicycles, electric bicycles, motorcycles, and mopeds face challenges in maintaining stability and preventing bending due to the weight and momentum of the vehicle, especially when parked.
Innovation Solution
A kickstand device with a pivotable member that pivots between a ground-engaging position to support the vehicle upright and a stowed position, featuring a mount portion with mount locations fore and aft of the vehicle, and a pivot axis in a plane between these locations to distribute torque and prevent bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mount location is used for the kickstand, then the device complexity is reduced, but the mount portion bends under the weight and momentum of the vehicle
Solution Approach 1:
The mount portion is divided into multiple mount locations (first mount location in fore direction, second mount location in aft direction) instead of using a single mount point. This segmentation distributes the torque and forces from the pivotable member across multiple attachment points on the vehicle frame, preventing bending while maintaining structural integrity.
2Ease of operation
If the kickstand uses a simple pivot connection, then the ease of operation is improved, but the stability is insufficient to maintain the vehicle upright
Solution Approach 1:
The pivot axis is positioned in a plane that is between the first and second mount locations in the fore-aft direction, creating a three-dimensional distribution of forces. This spatial arrangement of the pivot axis relative to the multiple mount locations provides both the simplicity of a single pivot connection for easy operation and the stability needed to maintain the vehicle upright through optimized force distribution.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kickstand effectively supports the vehicle upright and prevents bending of the mount portion by distributing torque across multiple mount locations, ensuring stability and durability.
Implementation Method 1
The pivotable member transfers a torque to the mount portion when pivoting about the pivot axis from the second position to the first position
Implementation Method 2
The pivotable member is pivotable between a first position to engage ground and retain the wheeled implement in an upright orientation
