Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow sliding boards lack the ability to tailor longitudinal flexural stiffness, torsional stiffness, and damping characteristics effectively, leading to suboptimal skiing dynamics and controllability.
Innovation Solution
A snow sliding board with a composite layer comprising strands fixedly connected to a substrate layer, where the strands are raised and protruding upwards, forming a strand geometry that distributes and dampens forces, and a multi-part core with varying distances between core profiles to enhance dynamics and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional layered composite is used without exposed strands, then the surface appears smooth and simple, but the ability to tailor flexural stiffness, torsional stiffness, and damping characteristics is limited
Solution Approach 1:
The patent applies local quality by varying the strand geometry and material properties in different regions of the snow sliding board. The composite layer includes strands with different orientations, densities, and material compositions in specific areas to locally optimize flexural stiffness, torsional stiffness, and damping characteristics for targeted skiing performance requirements.
Solution Approach 2:
The patent employs composite materials by integrating multiple materials with different properties into a unified composite structure. The composite layer combines substrate material with strand materials (such as carbon fibers, glass fibers, or natural fibers) in specific configurations to achieve tailored mechanical properties that cannot be obtained from single materials.
2Strength
If strands are embedded deeply into the substrate layer, then the surface remains smooth, but the force distribution and damping effectiveness are reduced
Solution Approach 1:
The patent applies dimensionality change by positioning strands at different depths and orientations within the composite layer. Some strands extend partially above the substrate layer while others are embedded at varying depths, creating a multi-dimensional arrangement that optimizes both force distribution capability and surface characteristics.
Solution Approach 2:
The patent segments the strand arrangement into different zones with varying embedding depths and orientations. This segmentation allows different regions of the composite layer to perform different functions: some strands prioritize force distribution while others maintain surface smoothness, achieving both objectives simultaneously through divided functional zones.
3Ease of operation
If a multi-part core with varying distances between core profiles is used, then dynamics and controllability are improved, but manufacturing complexity increases
Solution Approach 1:
The multi-part core features varying distances between core profiles at different longitudinal positions along the snow sliding board. The core structure has different spacing configurations in the front, middle, and rear sections to locally optimize dynamics and controllability for specific skiing maneuvers and terrain conditions.
Solution Approach 2:
The core design incorporates flexible elements and variable spacing that allow dynamic adjustment of the core's mechanical properties during skiing. The varying distances between core profiles enable the structure to adapt its stiffness and flexibility characteristics based on operational conditions, improving responsiveness and controllability.

AI summary
A snow sliding board includes multiple material layers arranged one above the other, including a substrate layer and a polymeric covering layer material, for example a synthetic resin, which covers the substrate layer on an upper side and forms a free surface on an upper side of the snow sliding board; and a strand geometry having one or more strands of strand material. The respective strand is fixedly connected to the substrate layer in order to form a composite layer and extends above the substrate layer, and the respective strand is raised protruding upwards and can be optically and haptically perceived as a raised structure on the upper side of the snow sliding board.
