Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current anti-theft systems for mobile computing devices, such as those using Kensington locks, are inconvenient, inefficient, and inadequate due to the need for a physical key, which can be lost, forgotten, or stolen, and the bulkiness of the lock and cable.

Innovation Solution

An authentication-based integrated lock mechanism is implemented on computing devices, utilizing an electronic authentication module, such as a fingerprint scanner, to authenticate users and activate an electromechanical mechanism to unlock the lock mechanism, eliminating the need for a physical key.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a physical key is used to lock and unlock the anti-theft system, then the lock mechanism can be securely operated, but the key can be lost, forgotten, or stolen

Engineering Contradiction:

ImprovesecurityVSAvoidconvenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical key-based locking system with an electronic authentication system using biometric sensors (fingerprint, face, or iris recognition). This substitution eliminates the physical key entirely, resolving the contradiction by providing both secure authentication (maintaining reliability) and convenience (eliminating key loss risks).

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary authentication module that acts as a mediator between the user and the lock mechanism. This module verifies biometric data and controls the electromechanical lock, providing secure authentication while eliminating the need for users to carry physical keys, thus resolving the contradiction between security and convenience.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a Kensington lock and cable are carried to protect the computing device, then theft prevention is enabled, but the lock and cable are heavy and bulky making them inconvenient to carry

Engineering Contradiction:

Improvetheft preventionVSAvoidportability

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent extracts the essential security function from the bulky physical lock and cable system, retaining only the necessary locking mechanism integrated into the device while eliminating the external cable and physical key components. This provides theft prevention without the weight and bulk of traditional Kensington locks.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the authentication and locking functions into an integrated system built into the computing device itself. The biometric sensor, authentication logic, and electromechanical lock are combined in a single unified system, eliminating the need for separate external lock and cable components, thus resolving the contradiction between security and portability.

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If a physical key system is used, then simple locking functionality is provided, but the system requires users to always carry the key

Engineering Contradiction:

ImprovesimplicityVSAvoiduser burden

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent implements a self-service authentication system where the device automatically captures and verifies biometric data without requiring user intervention beyond presenting the biometric trait (fingerprint, face, or iris). The system handles authentication and locking automatically, eliminating the burden of carrying and managing physical keys while maintaining operational simplicity.

Inventive Principle:

Principle #25Self-service

AI summary

A system and method of authentication-based operation of a lock mechanism include detecting an authentication signal from an electronic authentication module, authenticating the authentication signal using a stored user profile, wherein the stored user profile is used for login authentication purposes and includes at least user data, and when the authentication signal is authenticated, activating an electromechanical mechanism to release a latch switch associated with a lock mechanism.
