Vehicle Frame Component Layout for Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In two-wheeled vehicles, the uneven weight distribution between the front and rear wheels due to structural limitations, particularly in scooter-type vehicles, leads to instability and difficulty in controlling the vehicle, especially during emergency braking.
Innovation Solution
The vehicle design includes a main frame with strategically positioned components such as the power unit, power controlling unit, and battery receiving module, where the battery receiving module is placed between the power unit and power controlling unit, and the center of gravity is aligned to centralize weight distribution, ensuring both wheels bear similar loads, and components are arranged to shorten wiring lengths for reduced power loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the engine and related components are disposed in the rear of the vehicle due to structural limitations, then the vehicle can be assembled, but the rear wheel has a larger counterweight causing inflexible control and large inertial force during emergency braking
Solution Approach 1:
The patent redistributes components along the front-rear axis of the vehicle frame, placing the engine on the rear frame and the battery receiving module on the front frame. This spatial rearrangement shifts the center of gravity forward, balancing the weight distribution between front and rear wheels, thereby improving control flexibility while maintaining structural feasibility
2Device complexity
If the engine and related components are disposed in the rear of the vehicle, then the vehicle structure is simplified, but the rear wheel has large inertial force making it difficult to stop during emergency braking
Solution Approach 1:
The patent redistributes components along the front-rear axis, placing heavy components (engine) on the rear frame and lighter components (battery receiving module) on the front frame. This spatial rearrangement shifts the center of gravity forward, reducing the inertial force on the rear wheel during emergency braking, thereby improving stopping performance while maintaining structural simplicity
3Ease of operation
If components are arranged to centralize weight distribution, then vehicle stability and maneuverability are improved, but the wiring length between components increases
Solution Approach 1:
The patent positions the battery receiving module on the front frame and the engine on the rear frame, creating a distributed layout along the front-rear axis. This arrangement balances weight distribution to improve maneuverability while the wiring connects these spatially separated components, accepting increased wiring length as a trade-off for operational performance

AI summary
A vehicle includes a main frame, a power unit, a power controlling unit, and a battery receiving module. The power unit, a power controlling unit, and a battery receiving module are disposed on the main frame respectively. The battery receiving module is disposed between the power unit and the power controlling unit along a front-rear direction of the vehicle.
