Engine Testing TRIZ Cases
- Exhaust Pressure Detector for Semiconductor Manufacturing
A pressure sensor in a nitrogen-supplied chamber measures exhaust line pressure changes to detect clogging.
- Physical Quantity Detection Device Arithmetic Resolution Memory Trade-off
Arithmetic unit performs correction operations on sensor data using scaled conversion and gain adjustments to enhance output precision.
- Neutral Axis Weigh System for Vehicle Suspension
Sensors mount on equalizing beam neutral axes to measure axle weight, avoiding strain gauge wear and debris contamination.
- Endoscope Fixture Regulating Insertion Direction for Non-Coaxial Jet Engine Ports
Segmented columns bridge misaligned external and internal ports to enable precise blade inspection.
- Recirculated Exhaust Gas Burner for Emissions Testing
Burner-based exhaust gas generation system recirculates post-combustion flow to cool fresh output and simulate engine conditions.
- Piston Ring Drag Measurement Fixture Design
Rotatable arms support piston rings inside the cylinder bore to measure drag force without removing the piston assembly.
- Diagnostic Device for Material Handling Systems
Force sensors and accelerometers on a moving diagnostic unit detect alignment deviations and drag, reducing downtime in slat sorters.
- Fuel Injector Resilient Electrical Link for Nozzle State Detection
A resilient electrical link connects the valve member to the nozzle body, transmitting switching signals for state detection.
- Gas Sensor Atmosphere-Side Insulator Tilting Mechanism
Tilting atmosphere-side insulator maintains spring terminal contact with electrode terminals despite sensor element misalignment.
- Truck Rear Bed Durability Testing via Pseudo Fatigue Damage
A bench test method applies cyclic inputs to a separated truck rear bed assembly to replicate road load conditions.
- Fuel Pressure Sensor Mount Assembly Integration
A fuel pressure sensor mount assembly integrates detection devices directly into a connector unit to measure high-pressure fuel path dynamics.
- Hydraulic Impulse Damper for Pulsating Flow Measurement
An elastic membrane and spring-loaded buffer volume convert pulsating flows into continuous streams, enabling accurate measurement with simpler flow meters.
- Air Flow Sensor Thermal Stress Isolation Mechanism
Urging mechanism presses sensor assembly contact surface onto housing to stabilize position and block linear expansion stress transmission.
- Alternator Starter Tester Active Load Control
Dynamic power monitoring prevents protection tripping while enabling accurate performance assessment of defective components.
- Crash Test Carriage Segmentation for Rapid Setup
Segmenting the carriage into a fixed first unit and removable second unit reduces mass and preparation time while maintaining high acceleration dynamics.
