Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional water recirculating devices are used, then water purification and recycling can be achieved, but the cost is high and maintenance is frequent
Solution Approach 1:
The water recirculating path is divided into multiple separate paths (first water path, second water path, third water path) with different functions. The first path handles heating, the second path handles mixing, and the third path handles temperature regulation. This segmentation allows each component to be simpler and more reliable, reducing overall system complexity and maintenance requirements while maintaining effective water purification and recycling.
2Reliability
If conventional water recirculating devices are used, then water recycling can be achieved, but installation requires major modifications to existing infrastructure
Solution Approach 1:
The mixing valve arrangement is designed to accept water from multiple sources (first water path with heated water, second water path with cooler water, and optionally third water path with external water sources). This multi-functional design allows the system to be installed in various locations and integrated with different existing water infrastructures without requiring major modifications, while still achieving effective water recycling.
3Temperature
If conventional mixing valve arrangements are used, then water temperature can be regulated, but the system is highly dependent on the mixing valve and less customizable
Solution Approach 1:
The system provides dynamic temperature regulation by allowing the mixing valve arrangement to mix water from multiple temperature sources in different proportions. The control system can dynamically adjust the mixing ratios based on sensor feedback and user preferences, enabling customizable temperature settings for different outlets and conditions, thereby increasing system adaptability while maintaining effective temperature control.
4Manufacturing precision
If precise temperature control is implemented, then water quality requirements can be met, but system complexity increases
Solution Approach 1:
Temperature sensors are installed in each water path to continuously monitor water temperatures. This feedback information is used by the control system to automatically adjust the mixing valve positions and heating arrangement operations, achieving precise temperature control without requiring complex manual intervention or overly complicated control mechanisms. The feedback loop simplifies the control process while maintaining high precision.
