Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple differently designed propulsion units are used to suit different installation positions, then the adaptability to various installation positions is improved, but the device complexity and error probability increase
Solution Approach 1:
The patent applies universality by designing a single standardized propulsion unit that can be used in multiple installation positions through software configuration. The control system stores multiple configurations (e.g., different directions of rotation, power settings) and selects the appropriate one based on the installation position, eliminating the need for multiple physically different propulsion units while maintaining adaptability to various positions.
Solution Approach 2:
The patent changes operational parameters (rotation direction, power output, control settings) through software configuration rather than physical design variations. The control system adjusts these parameters based on the installation position to optimize performance, allowing the same hardware to adapt to different positions by modifying its operational characteristics.
2Adaptability or versatility
If multiple differently designed propulsion units are used for different installation positions, then the adaptability is improved, but the likelihood of errors during cabling and operation increases
Solution Approach 1:
By using identical propulsion units with standardized cabling requirements across all installation positions, the patent eliminates errors associated with different cable configurations. The universal design ensures that cabling procedures remain consistent regardless of position, reducing the likelihood of installation errors.
Solution Approach 2:
The patent uses identical copies of the propulsion unit design for all installation positions. Each unit is a copy of the standardized design, ensuring consistency in cabling, connectors, and operational procedures, which reduces errors during installation and operation.
3Ease of manufacture
If identically designed propulsion units are used with configuration selection, then the manufacturing simplicity is improved, but the device complexity for configuration management increases
Solution Approach 1:
The patent achieves manufacturing simplicity by producing identical propulsion units with standardized components and cabling. The configuration management is handled through software that automatically selects the appropriate settings based on installation position, reducing the complexity burden on manufacturing while maintaining operational flexibility.
Solution Approach 2:
The control system automatically selects the appropriate configuration based on the installation position without requiring manual intervention. This self-service approach to configuration management reduces the complexity burden on operators and simplifies the overall system deployment.
