Solution Overview

Problem

Existing security systems lack an automated solution for indicating a user's busy status within a room, which can lead to privacy breaches and unnecessary disturbances.

Innovation Solution

A user device equipped with a detection unit, analyzer, and communication unit that captures activity information, determines a busy status, and transmits this status to a lock to activate a privacy status, restricting access and indicating the user's busy status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a manual do-not-disturb tag is used, then privacy indication is provided, but user effort and forgetfulness are required

Engineering Contradiction:
Improveprivacy indication reliabilityVSAvoiduser operation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system uses sensors to automatically detect user activities (sleeping, bathing, etc.) and activates the privacy status without requiring manual user intervention. The lock system serves itself by monitoring user behavior patterns and autonomously determining when privacy protection is needed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical tag system is replaced with an automated electronic system using sensors, microcontrollers, and communication modules. The physical act of attaching a tag is substituted with automatic detection through motion sensors, temperature sensors, and other electronic monitoring devices.

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

2Reliability

If no automated busy status detection is implemented, then system complexity remains low, but privacy breaches occur due to lack of automatic indication

Engineering Contradiction:
Improveprivacy protection reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into independent functional modules: activity detection module with various sensors, analysis module for interpreting sensor data, communication module for transmitting status, and lock control module for executing privacy actions. Each module operates independently but coordinates through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lock system performs multiple functions: traditional locking/unlocking, automatic privacy status indication, user activity monitoring, and communication with hotel staff devices. This multi-functionality consolidates several systems into one unified platform.

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

3Productivity

If manual privacy tag placement is required, then system cost is low, but productivity and user convenience deteriorate

Engineering Contradiction:
Improveprivacy activation speedVSAvoidsystem implementation complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

Sensors are pre-installed in strategic locations (rooms, bathrooms, corridors) during hotel setup. The system is pre-configured with privacy rules and activity patterns, so that when a guest enters, the automated privacy detection is already in place and immediately operational without requiring guest setup actions.

Inventive Principle:
Principle #10Preliminary action
