Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a rocking-type swing motor is used with a single rotor driven by half of the coils, then the structure is simple, but the motor efficiency is low and the volume is large
Solution Approach 1:
The motor is divided into two independent rotor-swing lever systems (first rotor with first swing lever, second rotor with second swing lever), each capable of independent operation. This segmentation allows both rotors to be utilized simultaneously, improving motor efficiency while maintaining structural simplicity through modular design
Solution Approach 2:
Two rotor-swing lever systems are merged into a single motor structure sharing common stators and control circuitry. The linkage member merges the motion of both swing levers to drive the blade holder, allowing full utilization of both rotors while keeping the overall structure compact
2Ease of operation
If only half of the motor coils are utilized to drive a single rotor, then the control is simple, but the motor volume must be large to achieve required power
Solution Approach 1:
The motor coils are segmented into two independent sets, each controlling one rotor. This allows both coils to be utilized simultaneously, doubling the effective power output without increasing control complexity, as each rotor can be controlled independently through simple on/off switching
Solution Approach 2:
The motor transitions from utilizing one rotor in a single plane to utilizing two rotors in parallel, effectively adding a dimensional aspect to the power generation. This doubles the power output without proportionally increasing the motor volume, as both rotors share the same stator structure
3Device complexity
If a single rotor is used to drive the swing lever, then the structure is compact, but the electromagnetic efficiency is low
Solution Approach 1:
Two rotor-stator systems are merged into a single compact motor structure where both rotors operate simultaneously with shared stators. The linkage member merges the output of both swing levers to drive the blade holder, achieving high electromagnetic efficiency through dual rotor utilization while maintaining structural compactness
Solution Approach 2:
The magnetic conductive blocks are preliminarily positioned on the swing levers to concentrate and guide the magnetic flux from the rotors. This preliminary magnetic field concentration ensures maximum electromagnetic coupling between rotors and swing levers, improving electromagnetic efficiency without increasing structural complexity
