Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a common fluid path is used for multiple heat-related systems, then heat exchange efficiency is improved and surplus heat can be utilized, but temperature control precision for each individual system deteriorates
Solution Approach 1:
The patent divides the common fluid path into multiple independent control sections by installing separate flow rate control valves for each heat-related system. This segmentation allows individual temperature control for each system while maintaining the benefits of a common fluid path for heat exchange efficiency.
Solution Approach 2:
The patent applies different flow rate control strategies to different sections of the common fluid path based on the specific temperature requirements of each heat-related system. Each system receives customized flow control to achieve its optimal temperature while utilizing the common fluid for heat exchange.
2Speed
If flow rate control is implemented for each heat-related system, then temperature adjustment speed is improved, but device complexity increases
Solution Approach 1:
The patent uses a single common fluid path that serves multiple heat-related systems simultaneously, reducing the need for separate fluid circuits. This multi-functional approach allows one fluid system to perform multiple temperature control functions while maintaining fast response through individual flow control valves.
Solution Approach 2:
The patent employs flow rate control valves that utilize hydraulic or pneumatic principles to rapidly adjust fluid flow to each heat-related system. This enables fast temperature adjustment through fluid pressure and flow control without complex mechanical systems.
3Measurement precision
If temperature-related values are acquired from multiple electronic control devices, then temperature management accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent consolidates temperature data from multiple electronic control devices into a centralized control unit. This merging of information sources allows comprehensive temperature monitoring and coordinated control of multiple heat-related systems while simplifying the processing architecture through centralization.
Solution Approach 2:
The patent implements a feedback control mechanism where temperature-related values from multiple sources are continuously monitored and used to adjust flow rates in real-time. This feedback loop ensures accurate temperature management by constantly comparing actual temperatures with target values and making corrective adjustments.
