Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calorimeter designs are used, then measurement precision can be achieved, but manufacturing cost increases and measurement time extends
Solution Approach 1:
The calorimeter is divided into multiple independent measurement channels (first calorimetric channel, second calorimetric channel) that can operate simultaneously. Each channel has its own sample container and heat transducer assembly, allowing parallel measurement of multiple samples without interfering with each other, thus improving productivity while maintaining measurement precision
Solution Approach 2:
A heat transducer is introduced as an intermediary element between the sample container and the heat sink. This heat transducer efficiently mediates heat transfer from the sample to the heat sink while being measurable by the sensor, improving both heat exchange efficiency and measurement precision without extending measurement time
2Loss of energy
If traditional heat exchange configurations are used, then heat measurement can be performed, but heat exchange efficiency decreases and measurement time increases
Solution Approach 1:
The heat transducer serves as an efficient thermal intermediary between the sample container and heat sink, providing a dedicated heat transfer path that minimizes thermal resistance and maximizes heat exchange efficiency, thereby reducing measurement time
Solution Approach 2:
The system utilizes controlled thermal phase transitions and heat flow directions, where heat naturally flows from the warmer sample container through the heat transducer to the cooler heat sink, optimizing heat exchange efficiency without requiring additional energy input or extending measurement time
3Duration of action of stationary object
If sample flow through the calorimeter is implemented, then continuous measurement is possible, but measurement precision decreases due to inability to measure total heat flux
Solution Approach 1:
Instead of making the sample flow through the calorimeter, the invention inverts the approach by keeping the sample stationary in sealed containers and allowing heat to flow from the sample to the heat sink. This enables complete capture and measurement of total heat flux while maintaining measurement over extended periods
Solution Approach 2:
The sample flow function is extracted and removed from the system. Samples are kept stationary in sealed containers, and only heat is allowed to transfer to the heat sink for measurement. This extraction of the flow requirement enables precise measurement of total heat flux without the complications introduced by sample movement
