Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional snowboard binding systems are inconvenient and time-consuming due to the need for manual operation of complex linkages and straps, making it difficult to quickly attach and detach the snowboard boot, especially when using chairlifts or cable cars.

Innovation Solution

A binding system with a first portion attached to the snowboard boot and a second portion attached to the snowboard, featuring a pivoting spoiler and lever mechanism that allows the boot to be attached by simply pushing it onto the board, using push-button type couplings for quick and secure attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional binding systems with toothed tabs and ratchets are used, then secure attachment is achieved, but manual operation is required which is time-consuming and inconvenient

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidtime required for attachment and detachment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The binding system allows the boot to attach itself to the board through self-centering mechanisms and automatic engagement of coupling elements. The lever automatically triggers the release mechanism when actuated, eliminating the need for complex manual operations with toothed tabs and ratchets.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the complex mechanical system of toothed tabs and ratchets with a simpler lever-based coupling system. The lever acts as a cam that triggers the release of retention elements, substituting intricate mechanical interlocking with a more straightforward actuation mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If complex linkages and coupling systems are used to achieve fast binding, then attachment speed is improved, but device complexity increases and manual operation remains necessary

Engineering Contradiction:

Improveattachment speedVSAvoidcomplexity of linkages and coupling systems

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex linkage systems from the binding mechanism. Instead of using multiple interconnected components, the design focuses on a single lever that directly actuates the release mechanism, removing unnecessary intermediate elements.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than using complex linkages to transmit force from the lever to the retention elements, the patent inverts the approach: the lever itself becomes the actuating element that directly triggers the release through a cam mechanism, simplifying the force transmission path.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If manual operation of levers is required for attachment and detachment, then secure engagement is maintained, but ease of operation deteriorates especially when standing

Engineering Contradiction:

Improvesecure engagementVSAvoidease of operation while standing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The binding system incorporates self-centering mechanisms that automatically align the boot with the binding when the boot is placed on the board. The retention elements automatically engage with the coupling elements without requiring precise manual alignment, allowing users to attach while standing.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The binding system prepares the engagement mechanism in advance by positioning retention elements in a pre-loaded state. When the boot is placed on the board, the pre-positioned retention elements are ready to engage immediately, eliminating the need for manual alignment adjustments.

Inventive Principle:

Principle #10Preliminary action
