Solution Overview

Problem

Current mechanical binding systems for footwear and sport equipment, such as skis and snowboards, are complex and require manual operation for both binding and releasing, which can be cumbersome and unsafe in emergency situations.

Innovation Solution

A coupling assembly utilizing magnetic elements, specifically electromagnets, is integrated into the footwear and sport equipment binding, allowing for quick and secure attachment and detachment through an electronic control interface, including a proximity sensor and power management system, enabling wireless control via a bracelet or similar device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical binding systems with interlocks and springs are used, then stable binding is achieved, but the system becomes complex and requires manual operation for binding and releasing

Engineering Contradiction:
Improvestable bindingVSAvoidmechanical mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical binding mechanisms (interlocks, springs, ratchets) with a magnetic coupling system. Electromagnets mounted on the sport equipment interact with ferromagnetic elements in the footwear to create secure attachment, eliminating the need for complex mechanical components while maintaining binding stability.

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

Solution Approach 2:

The patent changes the fundamental binding parameter from mechanical interlocking to magnetic attraction. By controlling the magnetic field strength through electromagnet activation, the system achieves reliable binding without the structural complexity of mechanical safety mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If mechanical bindings with safety release mechanisms are used, then user safety is protected, but manual operation becomes cumbersome and slow in emergency situations

Engineering Contradiction:
Improvesafety protectionVSAvoidbinding and releasing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical release operations with electronic control of electromagnets. A microprocessor-controlled system can rapidly deactivate the magnetic field to release the footwear, or activate emergency release through wireless communication, dramatically reducing response time compared to manual mechanical operations.

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

Solution Approach 2:

The system incorporates automatic binding capability where the footwear is automatically attracted to and bound with the sport equipment when the electromagnets are activated, eliminating the need for manual binding operations entirely.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If electromagnets are used for automatic binding, then manual operation is eliminated, but power consumption increases and requires battery integration in the footwear

Engineering Contradiction:
Improveautomatic bindingVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent employs periodic or pulsed electromagnetic activation rather than continuous operation. The electromagnets are activated only when binding is required or during specific phases of use, reducing overall power consumption while maintaining automatic binding capability when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent divides the magnetic binding system into multiple independent electromagnets distributed across the sport equipment. This segmentation allows selective activation of only the necessary magnetic elements, optimizing power usage while maintaining effective binding.

Inventive Principle:
Principle #1Segmentation
