Solution Overview

Problem

Existing ski binding systems require athletes to stop or bend to manually adjust the binding position, disrupting rhythm and efficiency, especially in varied terrain, and are impractical for frequent adjustments during competitions.

Innovation Solution

A remote, electrically actuated system that allows athletes to dynamically change the ski binding's position longitudinally using buttons or levers on a glove or ski pole, with an electrical actuator and locking mechanism to securely maintain the chosen position, enabling adjustments without interrupting movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a manual actuator is used to change binding position, then the athlete can adjust grip and glide characteristics, but the athlete must stop or bend down to operate it, disrupting rhythm and losing time

Engineering Contradiction:
Improvebinding position adjustment capabilityVSAvoidtime lost during adjustment operation
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

A cable or rod mechanism acts as an intermediary to transmit the adjustment command from a remote location (hand grip area) to the binding mechanism, allowing the athlete to operate the system without stopping or bending down

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual lever or turning knob operation is replaced with a push-button or trigger mechanism that activates an electric motor, substituting direct mechanical operation with an automated electromechanical system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a manual lever or turning knob is used for binding adjustment, then the binding can be positioned between two or more longitudinal positions, but frequent adjustment becomes impractical due to the need to stop or bend down

Engineering Contradiction:
Improvebinding position variabilityVSAvoidease of frequent adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system allows the athlete to perform adjustments independently and continuously during motion through simple button presses or trigger pulls, making frequent adjustments practical and convenient

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Complex manual manipulation of levers or knobs is replaced with simple electronic button or trigger actuation, dramatically improving ease of operation for frequent adjustments

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If the binding position is fixed, then the device structure is simple, but the system cannot adapt to varying terrain conditions such as hilly trails

Engineering Contradiction:
Improveadjustment system complexityVSAvoidterrain adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The binding position transitions from a fixed static configuration to a dynamic adjustable configuration, allowing the system to adapt to varying terrain conditions while maintaining reasonable structural complexity through modular design

Inventive Principle:
Principle #15Dynamics
