Current methods for identifying helium-3 (He-3) concentrations in mining sites are inefficient, leading to unnecessary excavation and resource wastage, as they lack precise pre-mining assessments, affecting the economic viability of mining operations.

Innovation Solution

A mass spectrometer system integrated with a mobile carrier and a thermal neutron detection system, capable of operating in low-pressure environments, is used to detect He-3 concentrations by emitting and detecting thermal neutrons, with a neutron shield to isolate and measure backscattered neutrons, allowing for efficient mapping of He-3-rich areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional exploration methods are used to identify He-3 concentrations, then mining operations can proceed, but the assessment is imprecise leading to unnecessary excavation and resource wastage

Engineering Contradiction:
ImproveHe-3 concentration assessment precisionVSAvoidresource wastage
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent replaces conventional mechanical exploration methods (excavation, physical sampling) with a mass spectrometer-based detection system that uses thermal neutron emission and detection to identify He-3 concentrations non-invasively. This substitution eliminates the need for preliminary excavation while providing precise measurements, directly resolving the contradiction between measurement precision and resource wastage

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces thermal neutrons as an intermediary substance to detect He-3 concentrations. The mass spectrometer emits thermal neutrons that interact with He-3 atoms in the regolith, and the backscattered neutrons provide information about He-3 concentration without requiring direct contact or excavation of the material

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If comprehensive mining site assessment is conducted using traditional methods, then all areas can be evaluated, but the process is time-consuming and expensive

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The mass spectrometer system enables rapid, non-contact detection of He-3 concentrations across mining sites, replacing time-consuming mechanical excavation and laboratory analysis. The system can quickly scan and map He-3 distribution, significantly reducing assessment time while improving productivity by providing immediate actionable data

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent performs preliminary assessment of He-3 concentrations before any mining operations begin. By using the mass spectrometer to map He-3 distribution in advance, the system identifies high-concentration target areas, allowing mining operations to focus resources efficiently and avoid wasting time on low-yield areas

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If He-3 concentration mapping is performed accurately, then high-yield regions can be targeted, but the detection system complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The mass spectrometer system performs multiple functions: it emits thermal neutrons, detects backscattered neutrons, analyzes mass-to-charge ratios of ionized particles, and generates concentration maps. This multi-functionality achieves accurate He-3 mapping while consolidating what would otherwise require multiple separate systems into a single integrated device

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The use of thermal neutrons as an intermediary simplifies the detection mechanism. Instead of requiring direct interaction with He-3 atoms, the system detects backscattered neutrons that have interacted with He-3, providing accurate concentration data through a indirect but simpler measurement approach

Inventive Principle:
Principle #24Intermediary (Mediator)
