Solution Overview

Problem

Existing quick release buckles require sewing a webbing or ribbon, which is cumbersome, especially for small diameters like thin ribbons, and lacks reliability in emergency situations where sewing machines may not be available.

Innovation Solution

The use of a knot or melted-solidified-end at the end of the webbing or ribbon to attach it to the quick release buckle, employing a double-diameter or double-dimension point of connection for secure attachment without the need for sewing, allowing for greater strength and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If sewing process is used to attach webbing to quick release buckle, then attachment strength is improved, but ease of manufacture deteriorates due to requirement of sewing machine and complex sewing process

Engineering Contradiction:

Improveattachment strengthVSAvoidease of manufacture

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent replaces the sewing mechanical system with a melting and solidification thermal process. The webbing end is melted to form a molten droplet that solidifies to create a permanent attachment point, eliminating the need for sewing machines and complex sewing operations while maintaining attachment strength.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state parameter of the webbing material from solid to liquid and back to solid. By heating the webbing end to melting temperature, forming a molten droplet, and then allowing it to solidify, the attachment is created through phase transition rather than mechanical sewing.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If sewing process is used to attach ribbon to quick release buckle, then attachment is achieved, but ease of operation deteriorates due to difficulty in sewing thin and narrow ribbon

Engineering Contradiction:

Improveattachment reliabilityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the difficult mechanical sewing operation with a simpler thermal melting process. The ribbon end is melted to form a droplet that solidifies to create the attachment, which is much easier to perform than sewing thin and narrow ribbon, especially in emergency situations without specialized equipment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If knot method is used for attachment, then ease of manufacture is improved by eliminating sewing machine requirement, but device complexity increases due to double-diameter point of connection structure

Engineering Contradiction:

Improveease of manufactureVSAvoiddevice complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the attachment point structure with the quick release buckle body by integrating the double-diameter point of connection directly into the buckle housing. This eliminates the need for separate attachment components and reduces overall device complexity while maintaining the ease of manufacture advantage.

Inventive Principle:

Principle #5Merging (Combining)

4Productivity

If melted-solidified-end method is used, then productivity is improved by eliminating sewing process, but energy consumption increases due to heating and melting requirement

Engineering Contradiction:

ImproveproductivityVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical sewing process with a thermal melting process that can be performed quickly without specialized equipment. Although energy is required for heating, the overall process is faster and more productive, especially in emergency situations, as it eliminates the time-consuming sewing operation and equipment setup.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This method provides a stronger and more reliable attachment than traditional sewing, eliminating the need for a sewing machine and enabling quick connection-disconnection in various applications, including emergency scenarios.

Implementation Method 1

the method uses a double-dimension point of connection. For spheric shape melted-solidified-end, the double diameter as the one for the knot method is used.

AI summary

Two methods to attach a webbing or ribbon to a quick release buckle, and a quick release buckle for the use of the two methods are disclosed. Quick release buckles are designed to be used with webbing that is sewn to be attached to the quick release buckle, but for this invention two methods that do not require a sewing process are disclosed. One method uses a knot, and the other method uses a melted-solidified-end made on the webbing or ribbon using a melting method such as a flame or a hot iron or an ultrasonic welder.
