Solution Overview

Problem

Existing portable electronic devices are vulnerable to theft due to their high value, low weight, and small size, and conventional locking mechanisms can be easily bypassed by thieves using tools or knowledge.

Innovation Solution

An electromagnetic docking system comprising a base with ferromagnetic structures and a computing device with catch receptacles, using an electromagnet to unlock and eject the device from the base, providing a secure and user-friendly locking mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional locking mechanisms (cable locks, key locks, combination locks) are used, then the device can be secured to a fixed object, but the locking mechanism can be easily picked or cut with sufficient time and tools

Engineering Contradiction:

Improvesecurity against theftVSAvoidvulnerability to picking and cutting

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical locking mechanism (cable locks, key locks, combination locks) with an electromagnetic locking system. The electromagnet holds the computing device to the base, and when powered, it releases the device. This substitution eliminates the vulnerability to mechanical picking and cutting tools while maintaining security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the state of the locking mechanism from mechanical to electromagnetic by controlling the power state of the electromagnet. When the electromagnet is powered, it releases the device; when unpowered, it holds the device securely. This parameter change (powered/unpowered state) provides a different security mechanism that is not vulnerable to traditional mechanical attacks.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a cable lock is used to secure the device, then the device can be tethered to a fixed object, but the cable can be cut with wire or bolt cutters

Engineering Contradiction:

Improveanti-theft capabilityVSAvoidresistance to cutting

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent eliminates the physical cable lock and replaces it with an electromagnetic holding mechanism. The base includes a recess that receives the computing device, and the electromagnet provides holding force to secure the device without requiring a physical cable that could be cut. This provides anti-theft capability while eliminating the weakness of cable cutting vulnerability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If traditional lock mechanisms are used, then the device can be secured, but the locking and unlocking process requires physical keys or combinations that can be lost or guessed

Engineering Contradiction:

Improvesecurity controlVSAvoidlocking and unlocking convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces physical keys and combination locks with an electromagnetic control system that can be operated through power control. The electromagnet can be activated or deactivated through electrical signals, enabling remote or automated locking and unlocking operations. This improves ease of operation by eliminating the need for physical keys or memorized combinations while maintaining security control through electromagnetic engagement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The presently disclosed secure electromagnetic docking systems provide a simplified locking interface for the user and improved security overall. The secure electromagnetic locking mechanisms are hidden from view and access by a would-be thief, which is distinct from the generally accessible nature of prior art cable and lock mechanisms. The secure electromagnetic docking systems may also be locked and unlocked via a graphical user interface (GUI), thereby eliminating a requirement that the user successfully secure a cable and lock mechanism to a computing device and a fixed object. The secure electromagnetic docking systems may comprising one or more ferromagnetic structures are biased to a locked position. An electromagnet is selectively powered to move the one or more ferromagnetic structures to an unlocked position. In the unlocked position, one or more spring loaded ejectors are permitted to eject the computing device from the base.
