Earth Material Testing TRIZ Cases
- Soil CEC Analysis Using Electromagnetic Induction Sensing
Electromagnetic induction separates CEC measurement from turbidity-prone fluorescence, enabling more accurate soil fertility estimation.
- Nested Capacitive Soil Moisture Sensor for Fast Low-Energy Sensing
Nested capacitors separate electric fields to measure soil moisture quickly and accurately with lower energy use and a compact sensor layout.
- Quartz Crystallite Size Analysis for Depositional Form Identification
XRD crystallite size measurement distinguishes depositional quartz forms and excess silica in sedimentary rocks for better reservoir evaluation.
- Rock Drilling Parameter Control Using Real-Time Particle Size Feedback
Particle size sensing enables real-time drilling parameter adjustment to improve borehole quality and drilling efficiency during rock drilling.
- Mud Shale Hydrocarbon Volume Evaluation With Light Loss Correction
Light hydrocarbon correction and mass-balance modeling quantify discharged and externally charged hydrocarbons in mud shale.
- NMR Diffusion Tortuosity for Acid Diversion Efficiency
NMR-measured diffusion tortuosity quantifies acid diversion in carbonate rock samples, replacing labor-intensive methods with a faster diversion index.
- Rock Gas Diffusion Sampling Chamber for Pressure-Stable Measurement
An isolated sampling cavity enables gas analysis in rock diffusion tests without disturbing chamber pressure, improving coefficient accuracy.
- Ponded Infiltration Soil Testing With TDR for Fast Hydraulic Properties
Real-time TDR tracking of infiltration and wetting front enables fast in-situ soil hydraulic property measurement without sample disturbance.
- Substrate Moisture Sensor Modeling Inductance for Accurate Readout
By modeling probe inductance in the substrate impedance, this case improves water and nutrient readout accuracy in thicker media.
- Permafrost Landslide Test Rig for Coupled Temperature and Seepage
Integrated temperature, rainfall, seepage, and reservoir water control enables multi-field monitoring of permafrost landslide evolution.
- Cutting Ring Soil Infiltration for Fast Hydraulic Property Prediction
Using upward infiltration data from cutting ring soil samples, this case predicts hydraulic properties quickly while avoiding inversion non-convergence.
- Rock Sample Centrifuge Support Structure for Stable Unbalanced Rotation
A fixed and rotatable support member lets rock sample housings run without pre-balancing, reducing wobble, vibration, and separation error.
- Flow Manifold Permeability Measurement Without Low-Pressure Transducers
By zeroing cross flow in a branched manifold, this case measures high-permeability porous media without costly high-resolution pressure transducers.
- Solid Core Sample Analysis for Hydrocarbon Property Estimation
Solid core data is used to estimate fluid type, GOR, and CGR, cutting multiple fluid samples while improving reservoir analysis.
- Deep-Sea Polymetallic Nodule Ore Body Delineation Using Coverage Rates
Abundance-based boundaries can miss continuity; coverage and cumulative weighted averages define nodule ore bodies for mining-system and production needs.
