Solution Overview

Problem

Existing electronic devices with mirror displays lack the ability to seamlessly transition between mirror and display functions while accommodating user interactions, such as breath-based inputs for drawing or gesture recognition, without compromising functionality.

Innovation Solution

An electronic apparatus equipped with sensors and processors that detect user proximity and breath to control the mirror display's opacity and adjust drawing functions based on user gestures, allowing for a dynamic transition between mirror and display states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mirror display operates in mirror state to provide reflection function, then the reflectivity is maintained, but the user cannot interact with drawing functions or view displayed content

Engineering Contradiction:
Improvefunction switching capabilityVSAvoiduser interaction capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by enabling the mirror display to dynamically switch between mirror state and opaque state based on user interaction. The display transitions from a reflective surface to an opaque drawing surface when the user approaches and interacts, allowing seamless adaptation between viewing and interaction modes without manual configuration

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the optical parameter (opacity) of the display based on detected breath intensity. When the user exhales toward the display, the system adjusts the opacity parameter to transition from transparent/mirror state to opaque state, enabling drawing functionality. This parameter change allows the same physical display to serve multiple functions

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the mirror display transitions to opaque state for drawing function, then the drawing capability is enabled, but the mirror reflection function is lost in that area

Engineering Contradiction:
Improvedrawing function capabilityVSAvoidreflectivity
Core Design Contradiction:
Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The patent applies local quality by making only the specific area where the user exhales opaque, while the rest of the mirror display maintains its reflective properties. This localized state change allows the user to draw on a specific region without affecting the mirror function of the entire display surface

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The opacity state is dynamically adjusted based on real-time breath detection. When the user stops exhaling, the display area returns to its mirror state, allowing automatic transition between functions based on interaction duration and intensity

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If the system uses sensors to detect breath and gestures, then the user interaction precision is improved, but the device complexity increases

Engineering Contradiction:
Improvebreath detection accuracyVSAvoidsensor and processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical or manual interaction interfaces with breath-based detection. Instead of requiring physical contact with the display surface or complex gesture recognition systems, the invention uses breath detection to trigger and control drawing functions, simplifying the interaction mechanism while maintaining precision

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses the user's own breath as the interaction medium, eliminating the need for external controllers or complex input devices. The breath itself serves as the control signal, making the system more intuitive and reducing the complexity of external interaction mechanisms

Inventive Principle:
Principle #25Self-service

AI summary

An electronic apparatus including a mirror display, a sensor, memory storing one or more instructions, and one or more processors connected to the mirror display, the sensor and the memory to control the electronic apparatus. The one or more processors are configured to, by executing the one or more instructions, based identifying that a user's face approaches the mirror display within a threshold distance based on first data obtained via the sensor when the mirror display is in a mirror state and that the user exhales based on second data obtained via the sensor, control the mirror display to enter a drawing state by processing an area of the mirror display to be opaque based on the second data, and control the mirror display so that reflectivity of an area corresponding to a user gesture input in the opaque area increases.
