Snow Glide Board With Wing-Like Sections For Deep Snow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow gliding boards are not optimized for deep snow conditions, as they often compromise on width for reduced weight, leading to inadequate performance in deep snow environments.
Innovation Solution
A snow gliding board design with increased width perpendicular to its longitudinal extent, featuring a core that extends over its entire length, side sections with enhanced thickness, and a layered structure including a carbon fiber-reinforced shell and intermediate layer, which maintains mechanical strength and rigidity while reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the snow gliding board is designed with reduced weight, then the weight decreases, but the width perpendicular to the longitudinal extent decreases
Solution Approach 1:
The patent applies local quality by creating side sections with enhanced thickness (approximately two to three times the maximum dimension of steel edges) at specific locations along the snow gliding board. These localized thickened side sections are positioned outside the raised area and provide structural reinforcement for width and rigidity without adding material throughout the entire board, thus achieving increased width while controlling overall weight.
Solution Approach 2:
The patent resolves the width-weight contradiction by transitioning from a two-dimensional planar structure to a three-dimensional structure with variable thickness. The side sections extend in the third axial direction (Z-axis) with enhanced thickness, creating a volumetric form that provides both increased width perpendicular to the longitudinal extent and adequate structural strength without proportionally increasing weight.
2Area of moving object
If the snow gliding board is designed with increased width for deep snow, then the width increases, but the weight increases
Solution Approach 1:
The patent applies local quality by creating side sections with enhanced thickness (approximately two to three times the maximum dimension of steel edges) at specific locations along the snow gliding board. These localized thickened side sections are positioned outside the raised area and provide structural reinforcement for width and rigidity without adding material throughout the entire board, thus achieving increased width while controlling overall weight.
Solution Approach 2:
The patent segments the snow gliding board into distinct functional areas: a raised area for binding mounting, side sections with enhanced thickness for structural reinforcement and width, and transition areas connecting these regions. This segmentation allows each zone to be optimized for its specific function, with side sections providing width and strength only where needed.
3Strength
If the snow gliding board uses a layered structure with carbon fiber reinforcement, then the rigidity increases, but the manufacturing complexity increases
Solution Approach 1:
The patent employs composite materials by integrating a core structure with side sections that have enhanced thickness, creating a composite construction that combines different material properties. The side sections are formed from materials providing both structural strength and rigidity, while the core provides the base structure, achieving high rigidity through material composition rather than complex assembly.
Solution Approach 2:
The patent applies parameter changes by varying the thickness parameter of the side sections (approximately two to three times the maximum dimension of steel edges) and the longitudinal extent of these sections (35-45% of total length). These parameter optimizations allow the structure to achieve required rigidity with simplified manufacturing compared to uniform thickening or complex multi-layer constructions.

AI summary
The board i.e. ski (1), has a ski body (2) including a width, which is determined in Y-axis by a sum of widths of an elevated section (11) and wing-like sections (12). A part of the ski body width occupied by the wing-like sections, is larger than a width of the elevated section. A ski body thickness including the wing-like sections in a Z-axis, is approximately equal to double or triple of a maximum dimension, which includes steel edges provided at longitudinal sides of the ski body in the Z-axis.
