Snowboard Brake Linkage for Automatic Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snowboarding binding devices lack a secure and user-friendly braking mechanism, posing a safety risk and increasing the bulk on the snowboard.
Innovation Solution
A braking device that automatically transitions between a braking and non-braking position based on the tension of the shoe binding strap, utilizing mechanisms like a rocker, link, or cable to control the brake's position, ensuring secure engagement and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an independent braking device is mounted on the snowboard, then braking function is provided, but the device bulk and footprint on the snowboard surface increases significantly
Solution Approach 1:
The brake is integrated into the binding device structure, sharing the same base and mounting points. The brake assembly is positioned within the binding area, utilizing the same structural footprint rather than adding a separate independent braking system, thereby providing braking function without significantly increasing the device bulk on the snowboard surface
Solution Approach 2:
The binding device structure serves dual functions: securing the boot to the snowboard and housing the braking mechanism. The base and surrounding structure are designed to accommodate both the binding straps and the brake assembly, allowing one structure to perform multiple functions and avoid additional bulk
2Device complexity
If manual actuation of the brake is required, then braking control is simple, but ease of operation deteriorates as manual intervention is needed before practicing
Solution Approach 1:
The brake is pre-positioned in a retracted state within the binding device structure, ready for automatic deployment. The mechanical linkage is pre-configured so that when the boot is secured in the binding, the brake automatically moves to the engaged position without requiring manual actuation, thereby improving ease of operation while maintaining simple device complexity
Solution Approach 2:
The braking system is self-actuating through the mechanical connection between the boot-binding straps and the brake linkage. When the user secures their boot in the binding device, the tightening action automatically triggers the brake to engage, eliminating the need for separate manual intervention and making the system self-service oriented
3Reliability
If the brake is always in contact with the snow, then braking is always available, but the brake cannot be raised to a non-braking position for normal gliding
Solution Approach 1:
The brake is designed with dynamic positioning capability through a mechanical linkage connected to the binding straps. The brake can automatically transition between a lowered braking position (when straps are loose) and a raised non-braking position (when straps are tightened), allowing it to adapt its state based on operational conditions without manual intervention

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 provides a secure, user-friendly, and space-efficient braking system that automatically adjusts with the binding strap's tension, eliminating the need for manual intervention and reducing the device's footprint on the snowboard.

AI summary
A braking device for a sliding board, comprising a brake (24, 34, 44) capable of occupying a first braking position in which it occupies a low position suitable for rubbing the ground and a second non-braking position, in which it occupies a raised position, and comprising a means for controlling the position of the brake, characterized in that the means for controlling the position of the brake comprises a linkage means (22; 32; 42) adapted for a linkage with a strap of a shoe fastening device on a sliding board, so that the brake control means induces the automatic positioning of the brake in the non-braking position when a strap is closed and/or tightened on a shoe.
