Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electric motors operate with a wide range of voltages, then voltage adaptability is improved, but heat generation increases requiring heat sinks
Solution Approach 1:
The motor is divided into multiple submotors (first submotor, second submotor, third submotor) with separate winding sets. Each submotor can be independently controlled and connected in series or parallel configurations, allowing voltage adaptation without excessive heat generation in a single winding set.
Solution Approach 2:
The motor provides dynamic switching between series and parallel connections of submotor windings through a control circuit. This dynamic reconfiguration allows the motor to adapt to different voltage ranges while maintaining optimal current levels and heat generation characteristics for each operating condition.
2Temperature
If traditional electric motors use heat sinks for wide voltage operation, then temperature control is improved, but device complexity increases
Solution Approach 1:
Instead of adding heat sinks to a single motor structure, the system segments the motor into multiple submotors with independent winding sets. This segmentation allows voltage adaptation through connection configuration rather than thermal management add-ons, reducing overall device complexity.
Solution Approach 2:
The control circuit serves multiple functions: it manages the switching between series and parallel connections, adapts to different voltage ranges, and optimizes current distribution across submotors. This multi-functionality eliminates the need for separate heat sink components while maintaining temperature control.
3Adaptability or versatility
If multiple submotors are connected in series, then voltage range is improved, but current capacity decreases
Solution Approach 1:
The control circuit dynamically switches between series and parallel connections based on the required operating conditions. When high voltage is needed, submotors connect in series; when high current is needed, they connect in parallel. This dynamic switching resolves the trade-off between voltage range and current capacity.
Solution Approach 2:
The multi-submotor design with switchable connections provides universal adaptability to both high-voltage/low-current and low-voltage/high-current applications. The same physical configuration can deliver different electrical characteristics through connection reconfiguration, eliminating the need for separate motor designs.
4Productivity
If conductive wire length is increased for better performance, then motor efficiency is improved, but heat generation increases
Solution Approach 1:
The total conductive wire is segmented into multiple separate winding sets distributed across several submotors. This segmentation allows the use of longer total wire length for improved efficiency while distributing the heat generation across multiple separate locations, reducing the thermal load at any single point.
