Solution Overview

Problem

The existing belt buckle designs do not allow for easy variation in design or color to match different clothing styles without the need for purchasing multiple buckles or belts.

Innovation Solution

A belt buckle design featuring a top cover, bottom plate, and a replaceable insert, where the components are assembled via an interference fit or screw connection, allowing users to swap inserts of various designs or colors, thereby creating multiple design options from a single buckle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users purchase multiple belt buckles or belts to match different pants designs or colors, then design variety is improved, but economic cost increases

Engineering Contradiction:

Improvedesign varietyVSAvoidnumber of belt buckles

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The belt buckle is divided into separate components: a base buckle structure and interchangeable inserts. The insert can be removed and replaced with different designs, allowing one base buckle to serve multiple design purposes, thereby reducing the need to purchase multiple complete buckles.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base buckle structure is designed to be universal and accommodate multiple different inserts. This multi-functionality allows a single buckle base to provide various designs through insert replacement, enabling one item to fulfill multiple aesthetic functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If users purchase multiple belt buckles or belts to match different clothing styles, then design adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvedesign adaptabilityVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The buckle is segmented into a base structure and interchangeable inserts, creating a modular system. This segmentation allows for easy replacement of only the decorative insert portion while retaining the functional base, simplifying the overall system compared to owning multiple complete buckles.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The decorative insert is extracted as a separate, removable component from the complete buckle assembly. This extraction allows users to swap only the aesthetic portion without dealing with the entire buckle structure, reducing complexity in terms of replacement operations.

Inventive Principle:

Principle #2Taking out (Extraction)
