Directional Flock Ski Skin for Climbing Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconsistent quality of plush-like materials and complex manufacturing processes in ski skins lead to significant fluctuations in production costs and utility value, affecting their climbing behavior and adherence to skis.
Innovation Solution
A directional flock is applied to a carrier web at an acute angle of 10 to 80 degrees, preferably 20 to 75 degrees, which is anchored with a flexible glue that withstands varying temperatures, allowing for improved gliding and retention during uphill skiing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plush-like materials are used for ski skins, then climbing behavior is achieved, but quality fluctuates and manufacturing complexity increases
Solution Approach 1:
The patent changes the fundamental parameter of fiber orientation from random (plush) to directional (aligned at acute angles), transforming the material structure to achieve consistent climbing behavior while simplifying manufacturing processes and eliminating quality fluctuations associated with traditional plush materials
2Reliability
If plush-like materials are used for ski skins, then climbing behavior is achieved, but production costs increase
Solution Approach 1:
By changing the fiber orientation parameter from random to aligned, the patent eliminates the need for complex thermal processing and quality control measures, thereby reducing production costs while maintaining reliable climbing behavior
Solution Approach 2:
The patent applies directional alignment specifically to the fiber orientation in the climbing surface, creating local quality enhancement where it is most needed for climbing performance, while simplifying overall manufacturing and reducing costs
3Speed
If fibers are aligned at acute angles, then gliding performance is improved, but adhesion strength must be maintained
Solution Approach 1:
The patent creates different functional zones within the same material structure: acute-angle aligned fibers provide gliding performance in the climbing direction, while the carrier web and glue layer provide adhesion strength to the ski base, achieving both requirements simultaneously
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables stable and economic manufacturing of ski skins with enhanced climbing behavior and adherence, ensuring effective gliding and retention without slipping, thus improving the utility value and reducing production costs.
Implementation Method 1
The carrier web preferably consists of a textile material, in particular a fleece, to which the flock layer is applied electrostatically in a known manner.
Implementation Method 2
The flock is preferably anchored on the carrier web with glue. The glue must ensure the anchoring of the flock, be flexible and withstand high and low temperatures between + 50°C and - 40°C

AI summary
A ski skin is comprised of a carrier surface (1) coated with glue and a flock (2) applied thereto at an angle alpha. The flock (2) can be made of thermoplastic synthetic fibers. The production of the ski skin is accomplished more simply than that of previously known methods.
