Solution Overview

Problem

Existing buckles lack a reliable light-emitting function, making it difficult to locate the buckle in dark environments, which can lead to accidents, as they rely on short-lived reflections or luminance that is insufficient for warning purposes.

Innovation Solution

A light-emitting safe buckle design featuring a transparent or translucent male and female buckle with an integrated light-emitting device, including a control circuit board, LED lamps, a touch switch, and a battery, strategically positioned to provide a large and diffused light-emitting area, along with a guide rod and triangular notch for secure alignment, ensuring a striking visual warning and precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a reflection piece or luminous piece is added to the buckle, then the buckle can achieve reflection or luminous effect, but the reflection or luminous distance and luminous time are short, and the reflection or luminous position is small

Engineering Contradiction:
Improveluminous effectVSAvoidluminous time
Core Design Contradiction:
Illumination intensityVSDuration of action of moving object

Solution Approach 1:

The patent combines multiple light-emitting units (first light-emitting unit in the male buckle and second light-emitting unit in the female buckle) into a single buckle system. This merging of multiple light sources extends the overall luminous time and enhances the luminous effect, resolving the contradiction between achieving luminous effect and maintaining duration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from a single-point light source to a distributed light-emitting system across multiple components (male and female buckles). By adding spatial dimensionality with multiple light-emitting positions, the system achieves both extended luminous distance and prolonged luminous time while maintaining a compact structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If a light-emitting device is integrated into the buckle, then the buckle can provide warning effect, but the structure becomes more complex

Engineering Contradiction:
Improvewarning effectVSAvoidstructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The buckle system performs multiple functions: mechanical fastening (traditional buckle function) and light emission (safety warning function). By integrating these functions into a single universal device, the patent achieves reliable warning effect without proportionally increasing structural complexity, as the light-emitting components are embedded within the existing buckle structure.

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

Solution Approach 2:

The light-emitting devices are nested within the male and female buckle components. The first light-emitting unit is housed in the male buckle, and the second light-emitting unit is housed in the female buckle, allowing the light-emitting functionality to be contained within the existing buckle structure rather than adding external complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Illumination intensity

If the buckle is made of transparent or translucent material, then the light-emitting effect is enhanced, but the visibility of the buckle structure is reduced

Engineering Contradiction:
Improvelight-emitting effectVSAvoidbuckle structure visibility
Core Design Contradiction:
Illumination intensityVSShape

Solution Approach 1:

The buckle uses transparent or translucent material specifically in the regions where light emission is needed (male and female buckle bodies), while maintaining structural integrity through the inherent strength of these materials. This localized application of transparency enhances light-emitting effect without compromising the overall buckle structure visibility or function.

Inventive Principle:
Principle #3Local quality

AI summary

A light-emitting safe buckle is disclosed. The buckle includes, a light-emitting device, and a male buckle (2) and a female buckle (3) made of a transparent or translucent material, the light-emitting device being disposed on an intermediate setting portion (22) of the male buckle (2). The male buckle (2) and the female buckle (3) are both made of a transparent or translucent material, such that light emitted by the light-emitting device can be quickly conducted and diffused to the whole structure.
