Solution Overview

Problem

Existing cable lock systems for mobile devices require a key or combination to unlock, which can be inconvenient and prone to loss or forgetfulness.

Innovation Solution

A built-in security lock system for mobile devices using electromechanical actuators and locking elements that engage and disengage with a locking tab, controlled by a baseboard management controller (BMC) for secure locking and unlocking without the need for a physical key.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a key or combination lock system is used for mobile devices, then security is provided, but convenience deteriorates due to key loss or forgetfulness

Engineering Contradiction:

ImprovesecurityVSAvoidconvenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical key or combination lock system with an electromechanical actuator system controlled by a BMC (Baseboard Management Controller). The BMC receives unlock requests, controls the electromechanical actuators to disengage locking elements, and enables keyless unlocking via software interface, thereby eliminating the need for physical keys or memorized combinations while maintaining security through controlled access mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If an electromechanical locking system is implemented, then keyless operation is achieved, but device complexity increases

Engineering Contradiction:

Improvekeyless operationVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the electromechanical locking system into the existing BMC infrastructure of mobile devices. The BMC, which already serves as a management controller for system operations, is extended to handle locking and unlocking functions. This multi-functional approach allows the same controller to manage both traditional system operations and security locking mechanisms, thereby reducing overall system complexity despite adding keyless operation capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A security lock is provided for a mobile device. The security lock includes a pair of locking elements and a pair of electromechanical actuators. Each locking element has a profile configured to complement a profile of a locking tab of an external locking assembly. Each electromechanical actuator is configured to engage an associated one of the locking elements to lock the locking tab to the mobile device, and to disengage the associated locking element to unlock the locking tab.
