Solution Overview

Problem

Existing buckles with integrated whistles either increase the overall volume, are prone to damage, or have complex manufacturing processes, and expose the whistle to external contaminants, making them unsanitary and costly to produce.

Innovation Solution

A buckle design featuring a plug member with a guide rod configured as a whistle, accommodated within a socket member's chamber, minimizing external exposure and integrating the whistle seamlessly, allowing for easy manufacturing and sanitary use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the whistle is mounted on the buckle and protrudes outward, then the whistle can be easily accessed and used, but the entire volume of the buckle increases and the protruding portion may be obstructed or damaged

Engineering Contradiction:

Improveease of whistle useVSAvoidbuckle volume

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The whistle is nested within the socket member's chamber, with the guide rod positioned inside the chamber space. This allows the whistle to be integrated into the buckle's internal structure rather than protruding outward, maintaining compact volume while preserving accessibility through the open front end of the chamber

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the whistle is mounted on the buckle and protrudes outward, then the whistle can be easily accessed, but the protruding portion may be obstructed or damaged when it touches other objects

Engineering Contradiction:

Improveease of whistle useVSAvoidwhistle durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The guide rod is nested within the protective chamber of the socket member, shielding it from external obstacles and damage while maintaining operational accessibility. The chamber acts as a protective enclosure that prevents direct contact between the whistle and external objects

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The chamber structure provides a protective enclosure around the guide rod, creating a barrier that protects the whistle mechanism from external damage while allowing air flow for whistle operation

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If the whistle main portions are exposed to the outside, then the whistle can be easily used, but dust and foreign substances may easily enter the whistle making it unsanitary

Engineering Contradiction:

Improveease of whistle useVSAvoidcontamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The guide rod is nested within the socket member's chamber, which provides a protective enclosure that limits exposure to external contaminants while maintaining operational accessibility. The chamber structure creates a barrier against dust and foreign substances

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The chamber acts as a protective shell around the whistle mechanism, preventing direct contact between external contaminants and the whistle components while allowing air flow for proper operation

Inventive Principle:

Principle #30Flexible shells and thin films

4Adaptability or versatility

If the whistle is separately made and coupled to the plug member, then the whistle can be integrated into the buckle, but the manufacturing process becomes complicated and manufacturing cost increases

Engineering Contradiction:

Improvewhistle integrationVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The guide rod is configured as an integral part of the plug member, formed simultaneously with the plug member body rather than being a separate component. This merging of components simplifies the manufacturing process and reduces assembly steps while maintaining the whistle functionality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The guide rod serves dual functions as both a structural guide element for the buckle operation and as the whistle mechanism itself. This multi-functionality eliminates the need for a separate whistle component, simplifying manufacturing

Inventive Principle:

Principle #6Universality (Multi-functionality)

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

The buckle integrates the whistle without increasing volume, simplifies manufacturing, and ensures the whistle remains sanitary by encapsulating it within the socket member, reducing exposure to dust and foreign substances.

Implementation Method 1

If a user breathes out into a whistle, air passes through an air passage (flue) of the whistle so that air vibrations are generated to produce a high sound.

Methodology Applied

Scientific EffectAir vibrations: Vibration

AI summary

A buckle with a whistle includes: a plug member having lock arms extending forward from both sides of a base and a guide rod extending forward from the base in such a way as to be located between the lock arms; and a socket member having a chamber open on the front end thereof by means of an upper plate and a lower plate located to face each other so that the socket member is coupled to the plug member. The chamber is allowed to accommodate the guide rod therein. The guide rod is configured as the whistle. When the plug member is coupled to the socket member, the whistle is accommodated in the chamber.
