An assimilation of TRIZ in dissecting the statistical outcomes of tactile sensitivity, pinch force and endurance among elderly people

This study aims to examine tactile sensitivity effects on the pinch force and endurance of elderly people, propose solutions extending from statistical outcomes using theory inventive problem-solving (TRIZ). Pinch time data were collected among 32 subjects aged 55–65 years according a non-probability sampling method. Each participant received both treatments increased decreased through an experimental research design. Subjects pinched apparatus with different sensitivities, sustained their for as long possible. The results suggested that significant difference existed between reduced similar endurance. Resolving contradictions led partial-action principle, which people should less when they lack strength achieve certain level, rather than exert high in single attempt. segmentation other-way-around principles also recommended. Su-Field analysis found harmful pinching can be neutralised intermediary materials fingers object, such rubber. proposed optical or acoustic fields, where light sensors buzzers could act mechanisms signal users sufficient is achieved. These TRIZ-stimulated provide new insights resolving poor performance caused by degrading sensitivity.
