Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling and varying insulator heights are used for winding three-phase motors, then connection flexibility is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies homogeneity by making all insulator heights uniform rather than varying them. The insulator structure is standardized with consistent dimensions, eliminating the need for multiple insulator types or height adjustments during manual winding operations.
Solution Approach 2:
The patent implements self-service through the automatic winding machine that performs the entire winding and connection process without manual intervention. The machine automatically positions coils, creates connections, and manages the winding process, eliminating the need for manual handling operations.
2Manufacturing precision
If manual handling is used for winding three-phase motors, then connection accuracy can be adjusted, but manufacturing time increases
Solution Approach 1:
The patent replaces manual mechanical handling with an automated winding machine system. The machine uses programmed mechanical movements and automated positioning systems to achieve precise connections faster than manual operations, substituting human labor with automated mechanical systems.
Solution Approach 2:
The patent applies preliminary action by pre-programming the winding machine with precise positioning data and connection parameters before production begins. The machine is prepared in advance with all necessary winding patterns, insulator positions, and connection points programmed, enabling rapid accurate execution during manufacturing.
3Adaptability or versatility
If varying insulator heights are used for positioning connection lines, then positioning flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies homogeneity by standardizing insulator heights to be uniform across all positions. This eliminates the need to manufacture and inventory multiple insulator types with different heights, reducing manufacturing complexity and cost while maintaining positioning capability through the automated system.
Solution Approach 2:
The patent implements universality by designing a single standardized insulator that serves all positioning functions. The uniform insulator structure can be used in all positions and configurations required for different connection lines, replacing the need for specialized insulators with varying heights.
4Ease of operation
If manual winding operations are performed, then connection adjustments can be made, but reliability decreases due to misconnection risks
Solution Approach 1:
The patent implements self-service through the automatic winding machine that performs all positioning and connection operations without manual intervention. The system automatically ensures correct connections through programmed control, eliminating human error while maintaining the ability to make adjustments through machine programming rather than manual operations.
Solution Approach 2:
The patent applies feedback through the automated control system that monitors and verifies connection accuracy during the winding process. The machine uses sensors and control systems to detect positioning errors or potential misconnections and automatically corrects them, providing real-time feedback to ensure reliable connections.
