Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional complex mechanisms are used to move the partition wall, then the wall can be moved, but the device complexity and operational difficulty increase
Solution Approach 1:
The mechanism is divided into modular components: a driving pulley assembly, individual pulleys for each wheel, and separate tensioning devices. This segmentation allows each component to be simplified and maintained independently, reducing overall system complexity while maintaining functionality.
Solution Approach 2:
Pulleys and belts are introduced as intermediary elements between the motor and wheels. This intermediary mechanism transforms the motor's rotational motion into linear motion of the partition wall in a simplified manner, avoiding complex direct-drive mechanisms while ensuring smooth operation.
2Adaptability or versatility
If multiple swimming pools with different dimensions are provided, then different activities can be accommodated, but the space requirement and construction cost increase
Solution Approach 1:
The partition wall is made dynamically movable between fixed positions along the pool length, allowing the pool to be reconfigured from one large pool into two smaller pools of different dimensions. This dynamic adjustment eliminates the need for multiple fixed pools, reducing overall space requirements and construction costs while maintaining adaptability for different swimming activities.
3Reliability
If tensioning devices are added to the belts, then the reliability of the pulley system improves, but the device complexity increases
Solution Approach 1:
The tensioning devices are designed to automatically maintain proper belt tension through self-adjusting mechanisms, eliminating the need for manual intervention or complex control systems. This self-service approach ensures reliable operation while keeping the device structure relatively simple.
