Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple cooling channels are arranged within conductor stacks, then cooling capacity is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Multiple separate cooling channels are merged into a single central cooling channel that serves the entire generator strip. This consolidation maintains adequate cooling capacity while dramatically simplifying the cooling channel arrangement and reducing manufacturing complexity.
Solution Approach 2:
The central cooling channel performs the cooling function for the entire generator strip, serving multiple conductor stacks simultaneously. This multi-functional approach eliminates the need for separate cooling channels in each conductor stack.
2Reliability
If V2A steel alloys are used for cooling channels, then durability is improved, but manufacturing cost increases
Solution Approach 1:
The patent employs cost-effective materials such as aluminum or aluminum alloys for the central cooling channel instead of expensive V2A steel alloys. While the material lifespan may be shorter, the overall system reliability is maintained through the simplified design and reduced corrosion risks.
Solution Approach 2:
The patent utilizes composite material structures, such as aluminum alloys with enhanced surface treatments or composite coatings, to achieve both cost-effectiveness and adequate durability for the cooling channel application.
3Area of stationary object
If conductor stacks are arranged closely together, then space utilization is improved, but heat dissipation efficiency decreases
Solution Approach 1:
A central cooling channel acts as an intermediary thermal management element positioned between conductor stacks. This mediator efficiently extracts heat from multiple stacks simultaneously, enabling closer spacing while maintaining heat dissipation performance.
Solution Approach 2:
The patent transitions from distributing cooling channels within each conductor stack to a centralized cooling approach in the inter-stack region. This dimensional reorganization improves heat dissipation efficiency by providing dedicated cooling space without increasing overall footprint.
4Adaptability or versatility
If offset connections are used for cooling channels, then adaptability to conductor transposition is improved, but device complexity increases
Solution Approach 1:
Multiple offset connections are merged into a single central cooling channel connection point. This consolidation eliminates the need for complex offset connections while maintaining adaptability to conductor transposition through the centralized design.
