Snow Tiller Tooth Geometry for Two-Stage Snowpack Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow tillers face challenges in efficiently tilling snowpacks with varying conditions, leading to increased power consumption and vibrations, and require adjustments based on snow type.
Innovation Solution
A snow tooth design with staggered projections of different heights and orientations, allowing for two-step penetration into the snowpack, reducing power consumption and vibrations, and adapting to different snow conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rotating shaft with uniform teeth is used, then the device structure is simple, but the tilling performance varies poorly across different snow conditions
Solution Approach 1:
The snow tooth features two projections of different heights (first projection with height h1, second projection with height h2) arranged asymmetrically on the rotating shaft. This asymmetric design allows the tooth to penetrate snowpack at two different depths during rotation, enabling effective tilling across varying snow conditions without requiring multiple tooth configurations or adjustments.
2Use of energy by moving object
If traditional snow tiller teeth are used, then the structure is simple, but power consumption and vibrations increase during tilling
Solution Approach 1:
The snow tooth design creates a periodic two-stage penetration action as it rotates on the shaft. The first projection penetrates the snowpack to a certain depth, then the second projection (of different height) continues the penetration to a greater depth. This periodic alternating action smooths the load on the motor, reducing vibrations and power consumption spikes compared to uniform-depth teeth.

AI summary
A snow tooth for a snow tiller for preparing the snowpack of ski slopes; the snow tooth comprising a first projection having a first height and a second projection having a second height, the first height and the second height; the snow tooth being shaped so as to be connected to a rotating shaft and have, in use, a main direction of rotation. The first projection is arranged along the snow tooth so that, in use, the first projection sinks into the snowpack before the second projection in particular when, in use, the snow tooth is attached to a shaft of the snow tiller and the shaft rotates in the main direction of rotation.
