Abstract

This work explores possible solutions to the failure in operation of a pressure sensing device. The device operates inside the tyre of heavy earth moving equipment and is subject to temperature variations and exposure to fluids such as antifreeze. During extended operation it was observed that the device started to read higher values of pressure in time. The sensor and transmitter device are described. Initial investigation of failed sensors appeared to show some corrosion on the pressure sensor and it was assumed this was the reason for the increase in its reading. Cambridge Engineering Selector Edupack was used to select materials with increased resistance to antifreeze and moisture. TRIZ methodology was used to investigate contradictions between operating life and measurement accuracy. Different approaches to measuring pressure were explored using a TRIZ effects database. Possible solutions are offered involving including changing the pressure measurement system. Concluding comments discuss how TRIZ methodology in conjunction with other techniques can help students come up with innovative solutions to engineering and materials problems.
