Testing Metals TRIZ Cases
- Bipolar Plate Tab Structure for Clean Handling and QA Sampling
A detachable tab lets thin bipolar plates be gripped, tracked, and tested without deforming the plate body or contaminating its surface.
- Metal Strip Coil Unwinding for Low-Contact Dual-Side Inspection
A translating bogie unwinds metal strip coils with minimal contact, enabling inspection of both surfaces while limiting surface damage.
- Metal Strip Coil Unwinding With Minimal-Contact Surface Inspection
A translatable bogie and strip-end detaching element unwind metal coils with minimal contact, enabling inner and outer surface inspection.
- Eddy Current Probe for Formed Steel Tube End Inspection
Simultaneous eddy current sensing checks inner and outer formed tube ends faster, avoiding liquid-coupled testing and corrosion.
- Eddy Current Rebar Condition Detection Across Concrete Depths
Multiple magnetic sensors and depth-specific reference data improve non-destructive rebar corrosion and position detection in concrete.
- Steel Tube End Probe for Simultaneous Inner and Outer Wall Inspection
A matched eddy current probe inspects both walls of formed steel tube ends at once, improving defect detection while avoiding liquid testing.
- Ultramicroelectrode Cleaning for Ion Measurement in Organics
Potential cycles oxidize organic deposits on ultramicroelectrodes, enabling accurate ion measurement despite mass transfer issues.
- Gas-Pressurized Ionization Chamber Detector Arrays for Plate Strip Crown Measurement
Two rows of gas-pressurized ionization chamber detector arrays measure plate strip thickness and crown using collimated X-ray sources.
- Eddy Current Inspection of Spring Members Using AC Bridge Circuit
An inspection detector coil excites eddy currents in spring-shaped members to evaluate surface properties via an AC bridge circuit.
- Triaryl Phosphine Chemosensor for Copper and Platinum Detection
Triaryl phosphine chemosensors replace complex instrumental techniques by using catalytic depropargylation to quantify copper at 4.5 nM.
- Tailoring Syntactic Foam Dielectric Constant and CTE
Hollow particles with specific wall thickness and volume fraction tailor dielectric constant and CTE in syntactic foams without sacrificing strength.
- Electrochemical Probe Alloy Sorting via Impedance Spectroscopy
Electrochemical probes identify alloys via impedance spectroscopy, replacing slow optical methods to boost sorting throughput.
- Multiphase Flow Composition via Dual-State Molar Balance
Sampling gas and liquid at two thermodynamic states derives total composition without flow metering uncertainties.
- Multi-element Crystal Structure Determination via Metal Pair Grouping
A computational method groups candidate crystal structures using local order matrices and metal pair energies to estimate formation energy.
- Hot Metal Desulfurization via SO2 Fluorescence Analysis
Induction heating oxidizes hot metal samples to SO2 gas, enabling rapid ultraviolet fluorescence analysis that prevents excessive desulfurization agent usage.
