Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single temperature control unit is used for the entire measurement system, then the device complexity is reduced, but temperature gradients occur in regions near the measurement unit leading to unstable temperature control
Solution Approach 1:
The temperature control system is divided into multiple independent temperature control units, each responsible for specific regions or components. This segmentation allows different parts of the system to be controlled at different temperatures, preventing temperature gradients and improving overall temperature control stability while maintaining manageable complexity.
2Measurement precision
If the measurement unit temperature is controlled independently from the dispensing unit, then measurement accuracy is improved, but the device complexity increases
Solution Approach 1:
The system is segmented into separate temperature control zones with independent control units. The measurement unit has its own temperature control unit that can be independently adjusted from the dispensing unit, allowing optimized temperature conditions for accurate ion concentration measurements while keeping the overall system complexity manageable through modular design.
3Reliability
If heat insulation material is added between temperature control units, then temperature control stability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Heat insulation material is introduced as an intermediary element between different temperature control units. This intermediary prevents thermal interference between adjacent temperature zones, ensuring stable temperature control in each region. The heat insulation material is integrated into the system design in a way that minimizes assembly complexity while effectively isolating thermal fields.
