Solution Overview

Problem

There is a lack of automated solutions for securing specific areas within a building, such as homes or offices, which requires manual intervention by owners or caretakers to lock doors or cabinets when unexpected guests arrive, compromising privacy and safety.

Innovation Solution

The implementation of biometric sensors and processors to detect and differentiate between known users and guests, automatically securing areas by locking doors, cabinets, and adjusting device access based on biometric data, such as facial recognition, voice recognition, or fingerprint data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual intervention is used to secure areas when guests arrive, then privacy and safety can be maintained, but convenience and response time deteriorate due to requiring owners to physically lock doors and cabinets

Engineering Contradiction:

Improveprivacy and safetyVSAvoidconvenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service security by using biometric sensors to automatically detect unknown individuals and trigger securing actions without requiring manual intervention from the building owner. The system serves itself by autonomously comparing biometric data against known users and executing security protocols.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical actions (physically locking doors and cabinets) with an automated electronic system that uses biometric recognition and electronic control mechanisms to secure areas, eliminating the need for physical intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the building is kept in a fully open and accessible state, then convenience for owners is improved, but privacy and safety deteriorate when unexpected guests arrive

Engineering Contradiction:

ImproveconvenienceVSAvoidprivacy and safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts the security state of the building based on real-time biometric detection. When unknown individuals are detected, the system automatically transitions from an open state to a secured state by locking doors and cabinets. When only known users are present, areas remain accessible, providing adaptive security that responds to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements continuous feedback through biometric monitoring, where sensor data is constantly compared against known user profiles. This feedback loop enables the system to automatically adjust security measures based on the presence of authorized or unauthorized individuals, ensuring privacy and safety are maintained only when necessary.

Inventive Principle:

Principle #23Feedback

3Productivity

If automated biometric recognition is implemented, then response time and productivity are improved, but device complexity increases due to adding sensors and processing systems

Engineering Contradiction:

Improveresponse timeVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses multi-functional biometric sensors that can identify multiple known users and detect unknown individuals simultaneously. The same sensor and processing system handles both recognition of authorized users and detection of unauthorized persons, eliminating the need for separate systems and reducing overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a centralized processing system that acts as an intermediary between biometric sensors and security execution mechanisms. This intermediary coordinates the comparison of biometric data against known users and triggers appropriate security actions, simplifying the overall system architecture by centralizing control logic.

Inventive Principle:

Principle #24Intermediary (Mediator)
