Investigating Material Hardness TRIZ Cases
- Mammalian Limb Impact Simulator for Ground Stiffness Measurement
Physiological limb-impact loading with force and penetration sensing enables objective measurement of sports surface stiffness and damping.
- Portable Polymer Indentation Testing for In-Situ Cable Aging
Measures polymer cable aging in situ through portable indentation, capturing stiffness and recovery time without destructive sampling.
- Abrasion Ribbon Feed Control for Reproducible Surface Testing
Motor-driven ribbon winding prevents adhesion and tension drift, enabling reproducible surface abrasion tests with narrower ribbons.
- Abrasive Belt Tensioning for Reproducible Surface Testing
A winder and dancer tensioning setup keeps the abrasive belt off the specimen until loading, preventing adhesion and stabilizing abrasion tests.
