Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If heavy rotors are used to generate large amounts of torque, then torque output is improved, but motor weight and form factor deteriorate
Solution Approach 1:
The rotor is segmented into multiple permanent magnet assemblies arranged around the stator, with each assembly interacting with corresponding electromagnet segments. This segmentation allows torque generation through distributed magnetic interactions rather than requiring a single heavy rotor mass.
Solution Approach 2:
The patent replaces traditional electromagnetic induction mechanisms with a direct magnetic attraction and repulsion system using permanent magnets and electromagnets. This substitution eliminates the need for heavy rotors while maintaining torque generation capability through controlled magnetic pole interactions.
2Reliability
If traditional electromagnetic induction motors are specialized for vehicles and automobiles, then vehicle application performance is improved, but adaptability to small projects and general use deteriorates
Solution Approach 1:
The motor design incorporates adjustable parameters including variable numbers of electromagnets and permanent magnet assemblies, configurable pole arrangements, and scalable planetary gear track configurations. This universality allows the same basic design to be adapted for both vehicle applications and small projects.
Solution Approach 2:
The system allows dynamic configuration where the processor can selectively activate different numbers and arrangements of electromagnets and permanent magnets based on the specific application requirements, enabling the motor to adapt its characteristics for different uses from small projects to vehicle applications.
3Productivity
If planetary gear track is added to the motor system, then mechanical efficiency and torque optimization are improved, but device complexity increases
Solution Approach 1:
The planetary gear track is merged with the existing rotor assembly structure, where gear elements are integrated into the carrier assembly that already holds the permanent magnet assemblies. This merging approach adds mechanical advantage functionality without requiring completely separate gear mechanisms.
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
This solution enables efficient conversion of electrical energy into mechanical energy, providing a compact and efficient motor suitable for various applications by optimizing torque generation and motor efficiency through precise control of electromagnet polarity and planetary gear engagement.
Implementation Method 1
The discovery that electricity could create magnetic fields, which could in turn create electrical currents, was among the greatest scientific breakthroughs of the past century
Implementation Method 2
The motor is operated using attraction and repulsions forces, where a permanent magnet pole is attracted to a opposite and corresponding electromagnet pole and where the permanent magnet pole pushes against a same and corresponding electromagnet pole
Implementation Method 3
A planetary gear track can be mounted on the inside or outside of the permanent magnet assembly gear. When the track is mounted on the inside, the permanent magnet assemblies rotate in the same direction as the spindle. When the planetary gear track is mounted on the outside, the permanent magnet assembly rotates in the opposite direction as the spindle
