Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If empirical methods are used for geothermal potential study, then the study can be conducted with available data, but the accuracy of geothermal potential estimation deteriorates
Solution Approach 1:
The patent performs preliminary mapping of subsoil thermal conductivity and geothermal potential before installation design. This preliminary action creates accurate baseline data that enables precise dimensioning of geothermal installations, avoiding the need for empirical estimates while maintaining ease of study conduct through systematic pre-assessment.
Solution Approach 2:
The patent transforms the study approach by changing from empirical parameter estimation to measured parameter mapping. Thermal conductivity values and geothermal potential are determined through actual subsoil characterization rather than using generic empirical data, thereby improving estimation accuracy while keeping the study process manageable through structured methodology.
2Measurement precision
If systematic subsoil mapping is performed, then the accuracy of geothermal potential estimation improves, but the cost and complexity of the study increases
Solution Approach 1:
The patent creates a universal subsoil mapping methodology that can be applied to any location for geothermal assessment. The standardized approach to mapping thermal conductivity and geothermal potential makes the complex operation reusable and systematic, reducing the perceived complexity through established protocols while maintaining high accuracy through consistent data collection methods.
3Ease of manufacture
If geothermal installations are not accurately dimensioned, then the installation process is simpler, but the thermal efficiency and power transfer capability deteriorates
Solution Approach 1:
The patent performs preliminary and accurate determination of geothermal potential and thermal conductivity before installation design. This allows precise dimensioning of the geothermal system to match actual subsoil capabilities, ensuring optimal power transfer capability while maintaining installation simplicity through proper upfront planning and design based on measured data.
4Quantity of substance
If multiple geothermal installations are installed in an area, then the cumulative potential increases, but the individual efficiency of each installation deteriorates
Solution Approach 1:
The patent applies local quality mapping by determining specific thermal conductivity values and geothermal potential for different subsoil locations and characteristics. This enables optimized placement and dimensioning of multiple geothermal installations according to local subsoil conditions, ensuring each installation maintains high individual efficiency while contributing to cumulative regional potential through coordinated systematic deployment.
