Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geothermal systems require multiple geothermal holes and separate pumps for each, leading to high construction and maintenance costs, as well as inefficiencies in water management and heat exchange, particularly in regions with shallow underground water.
Innovation Solution
A geothermal system utilizing a single water supply system that collects and supplies underground water from multiple geothermal holes to a central facility, where it is used by a single heat pump and then returned, allowing for efficient heat exchange and reduced operational instability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple geothermal holes and separate pumps are used for each, then heat exchange capacity is improved, but construction cost and maintenance complexity increase
Solution Approach 1:
The patent merges multiple geothermal holes into a single water supply facility where underground water from multiple holes is collected and supplied through one pump to a heat pump. This consolidation maintains the heat exchange capacity of multiple holes while reducing system complexity and eliminating the need for multiple separate pumps, directly resolving the contradiction between power and device complexity
Solution Approach 2:
The single water supply facility serves multiple functions: it collects underground water from multiple geothermal holes, stores it, and supplies it to the heat pump system. This multi-functional design allows one facility to replace what would traditionally require multiple separate systems, reducing complexity while maintaining capacity
2Reliability
If multiple pumps are used for multiple geothermal holes, then water supply reliability is improved, but power consumption and maintenance cost increase
Solution Approach 1:
Multiple pumps are merged into a single pump located at the water supply facility. This single pump handles the water supply for all geothermal holes, reducing power consumption by eliminating redundant pump operations while maintaining reliable water supply through the centralized facility that collects water from all holes
3Productivity
If separate water supply facilities are used for each geothermal hole, then water management efficiency is improved, but construction cost increases
Solution Approach 1:
Separate water supply facilities for each geothermal hole are merged into a single centralized water supply facility. This facility efficiently manages water from all holes through centralized collection and supply mechanisms, maintaining water management efficiency while significantly reducing construction costs by eliminating the need for multiple separate facilities
Solution Approach 2:
The single water supply facility is designed with multi-functionality to handle water collection, storage, and distribution for multiple geothermal holes. This universal design achieves efficient water management across all holes while reducing construction costs compared to multiple separate facilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration simplifies maintenance, reduces power consumption, and lowers construction and operational costs by using a single pump and water supply facility, while maintaining stable water levels and quality, making it suitable for large-scale geothermal applications, especially in regions with shallow underground water.
Implementation Method 1
heat of the underground water supplied from the water supply means is used by a heat pump
Implementation Method 2
heat exchange is performed by underground heat again, whereby the temperature of the underground water is decreased or increased again

AI summary
A geothermal system includes: at least two geothermal holes (1) formed in the ground; a return water circulation tube (10) for returning underground water of the geothermal holes; a water collection and supply well (20) for collecting and then supplying the underground water returned by the return water circulation tube; at least one heat pump (30) for generating heat for cooling and heating, by using, as a heat source, the heat of the underground water supplied by the water collection and supply well; and a supply tube (40) which is an underground water supply means for supplying, to the geothermal holes, the underground water that supplied heat to the heat pump.
