Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorized bicycles with two wheels tend to sideslip, drift during braking, and lose balance when turning or starting, posing safety risks due to instability.
Innovation Solution
A vehicle frame design featuring a vehicle body mechanism, front wheel frame mechanism with pivotable front forks and cranks, and a rear wheel frame mechanism, incorporating shock-absorbing counteracting mechanisms to maintain front wheel contact and balance, enhancing steadiness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional motorized bicycle with two wheels is used, then the structure is simple, but the vehicle tends to sideslip, drift during braking, and lose balance when turning or starting
Solution Approach 1:
The front wheel assembly is divided into two independent front wheels that can move relative to each other, allowing each wheel to independently contact the ground and provide stability, rather than using a single rigid front wheel assembly
Solution Approach 2:
The front wheels are designed to be movable and adaptable rather than fixed, allowing them to adjust their position and contact with the ground dynamically in response to terrain variations, shocks, and steering inputs
2Reliability
If a front wheel frame mechanism with pivotable forks and cranks is used, then the front wheels can maintain ground contact and absorb shocks, but the device complexity increases
Solution Approach 1:
Multiple functions are combined into the front wheel frame mechanism: the pivotable front forks provide steering capability, the crank mechanism enables wheel articulation, and the counteracting mechanism absorbs shocks, all integrated into a single coordinated system
Solution Approach 2:
The counteracting mechanism is pre-configured to automatically activate when shocks occur, maintaining front wheel ground contact without requiring active control input from the rider
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 design improves controllability and stability by maintaining front wheel contact with the ground, absorbing shocks, and ensuring proper positioning during turns and bumps, thereby enhancing safety and balance during driving.
Implementation Method 1
The front-wheel counteracting mechanism is pivotably connected to the front exerting force pivot points of the front-wheel cranks and the front fork unit, and is configured to transmit upward and downward movements of the front wheels, to absorb shocks happened onto the front wheels

AI summary
A frame of a vehicle includes a front fork unit pivotably connected to a head tube of a vehicle body mechanism, a crank axle disposed on the front fork unit for two front-wheel cranks to be pivoted thereon. Two front wheels are pivotably disposed on the cranks, respectively. A front-wheel counteracting mechanism is pivotably connected between each of the cranks and the front fork unit to transmit an impact force to the cranks so as to cause opposite upward and downward movements of the front wheels to thereby keep the front wheels in contact with the ground and to render movement of the vehicle steady and safe.
