Solution Overview

Problem

Conventional razors lack an efficient mechanism for easy replacement of dull blade assemblies and do not offer sufficient flexibility to accommodate various handle designs and materials.

Innovation Solution

An interconnecting mechanism comprising an adaptor with a connector and a rotatable element, featuring outer and inner threads respectively, allows for secure connection and quick detachment of the blade assembly from the razor handle, while being compatible with diverse handle designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional razor designs are used, then the structure is simple, but the blade assembly cannot be easily replaced when dull

Engineering Contradiction:

Improveblade assembly replacementVSAvoidinterconnecting mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The razor is divided into separable components: a handle, a blade assembly, and an interconnecting mechanism. The interconnecting mechanism itself is segmented into a connector with outer threads and a rotatable element with inner threads, allowing independent replacement of the blade assembly while maintaining a secure connection system.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If conventional razor designs are used, then the manufacturing process is simple, but the razor cannot accommodate various handle designs and materials

Engineering Contradiction:

Improvehandle design compatibilityVSAvoidmanufacturing flexibility

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The adaptor is designed as a universal component that can interface with multiple handle designs and materials. The standardized connector with outer threads and the rotatable element with inner threads create a multi-functional interconnecting mechanism that accommodates various handle configurations while maintaining consistent manufacturing processes.

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 mechanism enables easy replacement of blade assemblies and provides users with customization options for handle designs, enhancing convenience and flexibility.

Implementation Method 1

a connector configured to be coupled with the handle engaging portion, the connector comprising one or more outer threads, a rotatable element comprising one or more inner threads. The inner threads of the rotatable element are configured to mate with the outer threads of the connector.

Methodology Applied

Scientific EffectScrew: Screw

Implementation Method 2

the deformable portion of the connector may comprise one or more elastic projections... when the rotatable element is rotated towards an engagement direction, the contacting surface deforms the elastic projections thereby connecting the rotatable element to the adaptor

Methodology Applied

Scientific EffectElasticity: Elasticity
