Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for uphill and forward traction on skis require significant physical effort from the skier and lack efficiency, as they do not effectively minimize resistance during forward motion while maximizing resistance in the reverse direction.
Innovation Solution
A unique denticle scale array pattern on the ski bottom, inspired by shark skin, which features a minimized footprint for forward motion and maximized footprint for uphill motion, with an OG curve profile and overlapping trailing edges to enhance traction and reduce friction, can be either fixed or removable.

Engineering Contradiction Analysis
1Productivity
If conventional wedge-shaped scales or plush fabric are used on the ski bottom, then forward and uphill traction is provided, but significant physical effort from the skier is required and efficiency is reduced
Solution Approach 1:
The ski bottom surface is segmented into multiple functional zones: a front section with a first pattern designed for forward motion and a rear section with a second pattern designed for uphill traction. This segmentation allows each zone to be optimized for its specific function, reducing the overall energy input required by the skier compared to using a single uniform pattern throughout.
Solution Approach 2:
Different regions of the ski bottom are given different surface qualities and patterns. The front section uses a first pattern with specific geometric characteristics optimized for minimizing resistance during forward motion, while the rear section uses a second pattern optimized for maximizing traction during uphill movement. This local differentiation of surface properties enables efficient performance across varying skiing conditions without requiring excessive physical effort from the skier.
2Ease of operation
If a uniform pattern is used across the entire ski bottom, then manufacturing is simplified, but resistance during forward motion cannot be minimized while maximizing uphill traction
Solution Approach 1:
The ski bottom is divided into distinct front and rear sections, each with its own optimized pattern. This segmentation allows the front section to minimize resistance during forward motion while the rear section maximizes uphill traction, achieving superior overall performance compared to a uniform pattern despite the increased design complexity.
Solution Approach 2:
The front section of the ski bottom is equipped with a first pattern specifically optimized for low resistance during forward motion, while the rear section receives a second pattern optimized for uphill traction. This local optimization of surface characteristics in different regions enables the ski to perform efficiently in both forward and uphill movements, improving ease of operation across diverse skiing scenarios.
3Ease of manufacture
If denticles are arranged in a simple array, then manufacturing is easier, but the dual function of low resistance in one direction and high resistance in the opposing direction cannot be achieved
Solution Approach 1:
The denticle patterns on the front and rear sections of the ski bottom are designed with asymmetric characteristics tailored to their specific functions. The front section's pattern is optimized for minimizing resistance during forward motion, while the rear section's pattern is optimized for maximizing traction during uphill movement. This asymmetric design achieves superior reliability in traction effectiveness while remaining manufacturable through conventional denticle array fabrication processes.
