Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a cylindrical motor with two permanent magnets is used, then the structure is simple, but the horsepower output is limited and energy consumption is high
Solution Approach 1:
The motor is divided into multiple independent functional rings (first ring with first permanent magnets, second ring with second permanent magnets, third ring with third permanent magnets) arranged concentrically. Each ring can generate torque independently, allowing the system to achieve high horsepower output through cumulative effect while maintaining simple individual structures that consume less energy
Solution Approach 2:
The invention transitions from a conventional cylindrical motor design to a multi-ring disc structure with concentric arrangements. This dimensional reorganization allows multiple permanent magnet sets to be stacked in the radial direction, increasing the effective magnetic interaction area and torque generation capacity without proportionally increasing energy consumption
2Power
If more permanent magnets are added to increase horsepower, then the torque and horsepower improve, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of using one large complex magnet arrangement, the system segments the magnetic components into three separate rings, each with its own permanent magnets arranged in specific patterns (alternating polarity in first and second rings, same polarity in third ring). This segmentation allows for easier manufacturing and assembly while achieving the desired torque through combined operation of all rings
Solution Approach 2:
The three functional rings are arranged concentrically with shared central axes, with each ring nested within the radial space of the others. The first and second rings are positioned at different radial distances from the center, creating a compact nested structure that maximizes space utilization and torque generation without increasing overall device footprint or complexity

AI summary
A multi-ring disc motor is revealed. The multi-ring disc motor includes a plurality of stator rings and a plurality of permanent magnets. The stator rings are disposed in a stator base and the permanent magnets are mounted on a plurality of circular ribs of a rotor base. The permanent magnets on the respective circular rib of the rotor base are corresponding to a coil on the stator ring in a respective circular groove of the stator base by the stator base and the rotor base connected to each other. Thereby high torque and high horsepower are generated by the stator rings on the stator base and the permanent magnets on the circular ribs of the rotor base. The power consumption is reduced effectively. Thus the battery life of vehicles such as cars is extended and this eliminates the needs to stop for charging.
