Solution Overview

Problem

Conventional doors with locks are opaque, leading to feelings of oppression when installed in spaces without windows, and existing access systems lack efficient electronic identification methods for secure door operation.

Innovation Solution

A door with a door access system featuring a translucent reflective layer, a double-sided mirror, and a light-transmittable mirror with a door access control device that uses electronic identification methods like facial recognition, fingerprint scanning, or PIN codes to control the door's locking state, allowing authorized access while maintaining privacy through mirrored surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a door is made opaque for privacy purposes, then privacy is improved, but the psychological feeling of oppression increases and natural light transmission is reduced

Engineering Contradiction:
ImproveprivacyVSAvoidpsychological oppression
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The door employs a two-sided mirror design where one side appears opaque/mirrored for privacy while the other side can transmit light. The mirror surface changes its optical properties based on which side is being viewed, allowing the door to provide privacy when needed while still permitting natural light to pass through, thereby eliminating the psychological oppression of completely opaque doors.

Inventive Principle:
Principle #32Color changes

2Illumination intensity

If a door is made completely transparent for light transmission, then natural light is improved, but privacy is lost

Engineering Contradiction:
Improvenatural light transmissionVSAvoidprivacy
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The door employs a two-sided mirror design where one side appears opaque/mirrored for privacy while the other side can transmit light. The mirror surface changes its optical properties based on which side is being viewed, allowing the door to provide privacy when needed while still permitting natural light to pass through, thereby eliminating the psychological oppression of completely opaque doors.

Inventive Principle:
Principle #32Color changes

3Reliability

If conventional locks are used on doors, then security is provided, but electronic identification and access control capabilities are lacking

Engineering Contradiction:
ImprovesecurityVSAvoidelectronic identification capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The door integrates multiple functions into a single system: the two-sided mirror provides both privacy and light transmission, while the embedded access control system accepts multiple identification methods (fingerprint, facial recognition, RFID cards, PIN codes) to provide versatile electronic authentication. This multi-functional design replaces conventional single-purpose locks with an intelligent system that adapts to different access control needs.

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

4Reliability

If opaque materials are used for doors, then privacy is improved, but the door cannot provide visual connection to the outside environment

Engineering Contradiction:
ImproveprivacyVSAvoidvisual connection to environment
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The door employs a two-sided mirror design where one side appears opaque/mirrored for privacy while the other side can transmit light. The mirror surface changes its optical properties based on which side is being viewed, allowing the door to provide privacy when needed while still permitting natural light to pass through, thereby eliminating the psychological oppression of completely opaque doors.

Inventive Principle:
Principle #32Color changes

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 system provides secure and transparent (literally and functionally) door access by allowing only authorized individuals to open the door, while maintaining privacy by ensuring the inside cannot be seen from the outside, thus addressing both security and psychological aspects of door operation.

Implementation Method 1

An intensity of a reflected portion of light reflected by the translucent reflective layer is greater than an intensity of a transmitted portion of the light transmitted through the second side to the first side of the door

Methodology Applied
Scientific EffectReflection: Reflection
