Solution Overview

Problem

Existing boot binding devices on gliding boards require tools for adjustment, are complex, bulky, and can lead to accidental misadjustments, compromising safety and performance.

Innovation Solution

An adjustable connecting element with a rod and play-recovery components that allows tool-free adjustment, featuring a blocking and adjustment configuration, with a lever-actuated camming surface to compensate for play, ensuring secure and user-friendly positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional toothed parts and guide rails are used for adjustment, then the binding device can be adjusted to different positions, but a tool like a screwdriver is required to release the toothed parts, making it not user-friendly and unsuitable for rapid adjustments

Engineering Contradiction:
Improvetool-free adjustmentVSAvoidcomplexity of release mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connecting element enables self-service adjustment by allowing the user to directly manipulate the blocking element (lever, button, or snap-fit component) without requiring external tools. The blocking element is designed to be manually actuated by the user's finger or hand, enabling independent adjustment of the binding device position along the guide rail.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The blocking element transitions between a locked position (engaging with the toothed part to fix the position) and an unlocked position (releasing the toothed part for movement). This dynamic switching mechanism allows rapid adjustment by simply actuating the blocking element, eliminating the need for tool-based operations.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple components and complex mechanisms are used to achieve adjustment, then the binding device can be securely fixed, but the solution becomes expensive, less reliable, and bulky

Engineering Contradiction:
Improvesecurity of fixingVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The blocking element is integrated directly into the connecting element structure, combining the functions of positioning, locking, and releasing into a single unified component. This integration eliminates the need for separate releasing mechanisms, reducing the total number of components while maintaining secure fixing through the toothed-part engagement.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting element serves multiple functions simultaneously: it guides the binding device along the rail, engages with the toothed part for positioning, and incorporates the blocking element for secure locking and easy release. This multi-functionality reduces component count while enhancing reliability.

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

3Adaptability or versatility

If traditional adjustment mechanisms are used, then the binding device can be adjusted, but unattractive mechanical elements are visible and the overall volume of the accessory increases

Engineering Contradiction:
Improveadjustability of positionVSAvoidvolume of connecting element
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The blocking element is nested within or integrated into the connecting element housing, allowing it to be concealed when not in use. The toothed parts and guide rails are designed to fit closely together, minimizing the overall volume while maintaining full adjustability along the rail length.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Ease of operation

If traditional toothed parts are used for adjustment, then the binding device can be positioned at different locations, but accidental misadjustments can occur during use, which is dangerous

Engineering Contradiction:
Improveease of adjustmentVSAvoidrisk of accidental misadjustment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The blocking element is designed to require deliberate user action to disengage from the toothed part, preventing accidental release during normal use. The blocking mechanism incorporates a safety feature where the blocking element must be actively pushed, pulled, or actuated in a specific direction to release the locked position, ensuring that inadvertent movements do not cause misadjustment or dangerous situations.

Inventive Principle:
Principle #9Preliminary anti-action
