Solution Overview
Problem
Conventional electric vehicles face limitations in range and efficiency due to the weight and inefficiency of separate battery, motor, and control unit components, which contribute to drag and reduced performance.
Innovation Solution
A power flywheel motor system integrates motor-generators, power supplies, and control devices with a flywheel to store and release energy, utilizing a shaft and traction surfaces to convert electrical energy into kinetic energy, allowing for efficient energy storage and release, and potentially reducing the need for traditional batteries and motors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate battery, motor, and control unit components are used in conventional electric vehicles, then the system provides reliable power storage and delivery, but the overall weight increases causing drag and reduced vehicle efficiency
Solution Approach 1:
The patent combines the battery, motor, and control unit into a single integrated power unit housing. The battery is positioned within the housing, the motor is coupled to the battery, and the control unit is integrated into the same assembly, creating a compact unified system that reduces overall weight and drag while maintaining all necessary functions
Solution Approach 2:
The motor-generator assembly serves multiple functions: it acts as both a motor to drive the vehicle and a generator to recover energy during braking. The single assembly performs propulsion, energy recovery, and power management functions that would otherwise require separate components, reducing overall system weight
2Adaptability or versatility
If traditional separate components (battery, motor, control unit) are used, then each component can be optimized independently, but the overall system size and complexity increase
Solution Approach 1:
The battery, motor, and control unit are merged into a single integrated power unit with a common housing and shared mounting structure. This consolidation reduces the number of separate assemblies, connection points, and mounting requirements, thereby reducing system complexity while maintaining independent optimization of each component within the integrated architecture
3Use of energy by moving object
If flywheel assembly is integrated with motor-generator, then energy storage capacity is enhanced and weight is reduced, but the mechanical complexity of the integration increases
Solution Approach 1:
The flywheel assembly is nested within the motor-generator assembly, with the flywheel positioned inside the motor housing. The motor-generator is itself integrated within the power unit housing that contains the battery. This nested arrangement allows multiple energy storage mechanisms (chemical energy in battery, kinetic energy in flywheel) to coexist in a compact configuration, enhancing total energy storage capacity while managing mechanical complexity through hierarchical integration
