The worn out Teflon cap on a wind turbine ventilator had blocked it from spinning efficiently. Redesigning the cap's shape to fit the central shaft better could reduce friction and prevent wear, but would require manufacturing a new mold. Alternatively, adding magnets to the cap could create a gap with the shaft during spinning and prevent direct contact without changing the ventilator's design.

Problem Statement The Wind Turbine Ventilator worn out Teflon cap had blocked the wind turbine ventilator spinning which had affected the efficiency of the wind turbine ventilator. Boundary Condition Size of wind turbine ventilators at 16 inch. The material of central shaft is stainless steel. The surface design of the turbine ventilator can not be change.
Part 3
Engineering Contradiction If the Teflon cap did not worn out by the central shaft, than the efficiency of the ventilator will be increase but the assembly parts will be difficult and manufacturing cost will be increase duo to a new mole for a new shape Contradiction Matrix
Substance Field ModelClass 1.2 of Inventive Solution
1.1.2 Changing the shape of the Teflon cap (S3) to fit with the shape of the head of central shaft will be able to reduce the friction between the Teflon cap and the central shaft 1.2.3 Adding the magnet (S3) to the Teflon cap to provide a gap between the central shaft and the Teflon cap which can prevent friction force occur when the ventilator spinning due to central shaft and the Teflon cap is not direct contact to each other.
