Variable Curve Saw Blade Ramp Elements for Uniform Wear

The patent applies local quality by varying the curvature radius of ramp elements at different locations along the blade. Specifically, the curvature radius changes from a first value at a first location to a second value at a second location, creating non-uniform pressure distribution that compensates for the varying loads on different teeth. This localized variation in geometric properties ensures more uniform wear across all teeth while maintaining the beneficial rocking motion.

The patent implements parameter changes by systematically varying the curvature radius parameter of ramp elements along the blade length. The curvature radius transitions from a first value to a second value, creating a controlled non-uniform pressure distribution. This parameter variation maintains the curved cut pattern capability while ensuring more uniform wear distribution across teeth, thereby extending blade life.

The patent resolves this contradiction by applying local quality principles - while ramp elements maintain consistent basic geometry for ease of manufacture, the curvature radius parameter is locally varied along the blade length. This allows standardized manufacturing processes to be used with modular ramp elements, while the progressive variation in curvature radius compensates for non-uniform pressure distribution, preventing early blade failure.
