Solution Overview

Problem

Individuals struggle to achieve salon-quality hairstyles at home due to the inability to see and style the back of their own heads effectively, and existing tri-fold mirrors and video tutorials fall short in providing practical application.

Innovation Solution

A tri-fold smart mirror with integrated HD display, storage compartments, and advanced hairstyling capabilities, featuring a 360-degree view and interactive tutorials, allowing users to project their back head onto the mirror for precise styling and access a range of tutorials through a mobile app.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional mirrors are used for hairstyling, then the mirror structure is simple and成本低, but the user cannot see the back of their head and achieve salon-quality hairstyles independently

Engineering Contradiction:
Improveability to style back of head independentlyVSAvoidmirror structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines a traditional mirror with a video display system, camera, and computing device into an integrated smart mirror apparatus. The video display is positioned behind a two-way reflective surface, allowing the mirror to function both as a traditional reflective surface and as a display screen for showing live or recorded video of the back of the user's head, thereby enabling independent hairstyling without requiring external assistance

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system uses a camera to capture images and video of the back of the user's head, then displays these visual copies on the video display through the two-way reflective surface. This allows the user to see and style the back of their head as if looking directly at it, replicating the visual information that would otherwise be unavailable to them

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If external assistance from hairdressers is used, then salon-quality hairstyles can be achieved, but it is costly and time-consuming

Engineering Contradiction:
Improvehairstyling qualityVSAvoidtime for salon visits
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The smart mirror system enables users to perform hairstyling themselves by providing real-time visual feedback of the back of their head through the video display. Users can watch live video or recorded tutorials showing the back of their head, allowing them to replicate professional hairstyling techniques at home without needing to visit salons or rely on external assistance

Inventive Principle:
Principle #25Self-service

3Loss of information

If video tutorials are used for hairstyling, then instructional content is available, but users cannot visualize steps for styling the back of their heads

Engineering Contradiction:
Improvevisual feedback availabilityVSAvoidtutorial application effectiveness
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system uses a camera as an intermediary to capture the back of the user's head and a video display as another intermediary to present this visual information to the user. This intermediary system bridges the gap between the user's limited self-view and the need for comprehensive visual feedback, allowing users to see exactly what they are styling without needing to physically turn around or rely on external observers

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Enables users to achieve salon-quality hairstyles independently by providing a clear view, integrated storage, and interactive tutorials, saving time and money while enhancing the user experience in personal grooming.

Implementation Method 1

A one-way reflective surface is provided over the top of an interactive display. A person in front of the reflective surface can see a normal reflection as would be provided by a conventional mirror. The person can also see images created by the interactive video display that are transmitted through the one-way reflective surface.

Methodology Applied
Scientific EffectOne-way reflection: Reflection
