Solution Overview

Problem

Existing snow hiking boards and skis are either cumbersome for uphill climbing or lack stability and control during downhill sliding, requiring complex modifications between ascent and descent phases, and often require a high technical skill level.

Innovation Solution

A compact, edgeless gliding board with a series of notches on its side edges, designed to provide axial attachment and anti-recoil functionality, allowing secure uphill movement and controlled downhill sliding without the need for modifications, featuring a core with partially hollowed areas and an underside with anti-recoil skin or scales for enhanced traction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional ski edges are used, then downhill sliding control is improved, but uphill climbing becomes difficult and requires skin attachment/detachment

Engineering Contradiction:
Improvedownhill sliding controlVSAvoiduphill climbing ease
Core Design Contradiction:
SpeedVSEase of operation

Solution Approach 1:

The side edges are segmented into multiple notches instead of being continuous, creating discrete engagement points with the snow that provide both uphill retention and downhill control without requiring separate skin attachments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The notched side edges serve multiple functions simultaneously: they provide anti-recoil during uphill climbing, enable controlled downhill sliding, and eliminate the need for separate skin attachments, making the board versatile for both ascent and descent phases

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Speed

If symmetrical undulations are provided on side edges, then downhill sliding is facilitated, but uphill anti-recoil capability is lost

Engineering Contradiction:
Improvedownhill sliding facilitationVSAvoiduphill anti-recoil capability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The notches are designed with asymmetric geometry where the transverse abutment faces are inclined at different angles (0°-15°) compared to the longitudinal connecting faces (60°-85°), creating directional resistance that prevents backward movement during uphill climbing while allowing forward sliding during descent

Inventive Principle:
Principle #4Asymmetry

3Stability of the object's composition

If conventional ski structure with edges is used, then downhill stability is improved, but device complexity and handling difficulty increase

Engineering Contradiction:
Improvedownhill stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the traditional metal edge component from the ski structure, replacing it with notches directly formed in the board's side edges, thereby simplifying the overall structure while maintaining downhill stability and control capabilities

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present invention relates to a ski touring board, intended to receive a boot binding (F) comprising an upper face, an lower face and lateral edges, characterized in that at least one of the lateral edges of the board is provided with a series of notches (11) of which each edge (11a) delimits, on the one hand, a transverse stop face (12) allowing the board to be stopped in the direction of the backswing and, on the other hand, a longitudinal connecting face (13) between the notches (11) allowing the forward sliding.
