Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If cylindrical-type motors are used in hybrid or electric vehicles, then the vehicles can run on electricity, but the horsepower generation is limited and frequent charging is required
Solution Approach 1:
The patent transitions from a cylindrical motor geometry to a disc-type motor geometry. This dimensional change allows for a larger radius of torsion and more permanent magnets to be arranged along the periphery, significantly increasing the torque and horsepower generation capability while maintaining a compact form factor.
Solution Approach 2:
The disc-type motor divides the magnetic components into multiple segments - specifically three or more permanent magnets and three or more induction coils arranged around the periphery of the disc. This segmentation allows for increased power generation compared to the two-magnet cylindrical design while distributing the magnetic flux more effectively.
2Power
If more permanent magnets and larger radius are used to increase horsepower, then torque and power increase, but the motor size and weight increase
Solution Approach 1:
By adopting a disc-type configuration with a larger radius of torsion, the motor achieves greater leverage and torque multiplication without proportionally increasing weight. The flat disc geometry allows for optimized material distribution that maximizes power-to-weight ratio.
Solution Approach 2:
The motor utilizes composite construction combining permanent magnets, induction coils, and magnetic cores in a disc configuration. This composite approach allows each component to be optimized for its specific function while working together to achieve high power output relative to the total motor weight.
3Power
If hybrid vehicles use both gasoline engine and electric motor, then power is increased, but the vehicle becomes more expensive and heavier
Solution Approach 1:
The patent merges the functions of the gasoline engine and electric motor into a unified disc-type dynamic motor system. The induction coils can be energized to create electromagnetic fields that interact with the permanent magnets, allowing the motor to operate in different modes (electric propulsion, regenerative braking, or engine-assisted) without requiring separate cylindrical motor and engine systems.

AI summary
An energy efficient vehicle and a disc-type dynamic motor thereof are disclosed. The vehicle comprises front wheels and rear wheels, and a gasoline engine is assembled in the vehicle for driving a generator producing power. The power is transported to a capacitor battery via a circuit control system and then to disc-type dynamic motors, which are assembled with the rear wheels, from the capacitor battery via two power lines respectively, whereby the disc-type dynamic motors directly to driving the vehicle travelling at high-speed and high torque via the wheels. Accordingly, the energy efficient vehicle does not include transmission devices, such as the clutch, the transmission, the power transmission shaft, and the differential. The power produced by the generator is directly provided to the disc-type dynamic motors to drive is the vehicle travelling and is enough to drive the disc-type dynamic motors, so the vehicle does not need to stop for charging.
