Abstract
ABSTRACT
This research applies Quality Function Deployment (QFD) theorem and Theory of Inventive Problems Solving (TRIZ) on anti-bedsore facility for use on bedridden patients suffering from acute or chronic disease. To design a better facility to prevent patients from bedsore, instead of regular labor care to turn body over. Firstly, to understand the root causes of bedsore and know about the shortcomings existed on current methods, theories or instruments available to avoid bedsore. We list patient’s requirements on anti-bedsore instrument, converting those requirements into engineering characteristics and give each a weight. Then utilize Function mechanism Deployment to analyze the mechanism demands of design requirement on anti-bedsore instrument. Through systematically QFD process, we realize the function requirements, mechanical composition and technique that need to be improved on anti-bedsore instrument. Then apply TRIZ to define the points on anti-bedsore, perform ideality analysis and find useful resources. After doing Substance-Field Analysis and analyzed by Table of Contradictions, TRIZ 40-principle and single characteristic principle are good to find solutions on improving anti-bedsore design. Afterwards, by searching patent database of different countries, we find some examples for further discussions on how those theorems applied on anti-bedsore instrument’s design concept.
