Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the main body portion length is increased to accommodate large-scale cells (580 mm), then the device can process longer batteries, but the device complexity increases
Solution Approach 1:
The main body portion is divided into multiple sections with channels arranged in segments along the length. This segmentation allows the device to handle long cells (580 mm) by processing different sections independently, reducing the complexity of managing a single large continuous structure.
Solution Approach 2:
Channels are arranged not only along the length but also in the width direction, creating a two-dimensional distribution pattern. This dimensional approach allows efficient coverage of large cell surfaces without requiring excessive length in a single direction, thereby managing device complexity.
2Productivity
If multiple channels are added to improve foreign substance removal efficiency, then the removal efficiency increases, but the device complexity increases
Solution Approach 1:
Multiple channels are segmented and distributed across different locations (length and width) of the main body portion. Each channel operates independently to remove foreign substances from specific areas, improving overall removal efficiency while maintaining manageable complexity through modular arrangement.
Solution Approach 2:
The channels serve multiple functions: they remove foreign substances, guide airflow, and can be configured to handle different types of contaminants. This multi-functionality increases removal efficiency without proportionally increasing device complexity.
3Productivity
If channels are separated and optimized for specific regions, then foreign substance removal efficiency improves, but the manufacturing precision requirements increase
Solution Approach 1:
Channels are segmented into distinct regions (first and second channels in different locations) that can be manufactured and positioned independently. This segmentation allows for standardized manufacturing modules that reduce precision requirements compared to a single complex integrated channel system.
Solution Approach 2:
Different channel regions are optimized for local requirements - some channels may be positioned to handle specific types of foreign substances or target particular areas of the cell. This local optimization improves removal efficiency while allowing each section to be manufactured with appropriate precision standards.
