Electronic Device Theft Alert via Locking Device Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require a separate alarm device and recognition signal to prevent theft, leading to complex circuits and additional costs, with alarms only being output from the separate device and not from the electronic device itself, making it ineffective for theft prevention.
Innovation Solution
An electronic device with a processor that detects a connection with a locking device, receives its identifier, sets an alarm mode, and outputs an alarm when disconnected, eliminating the need for a separate signal line and alarm device by utilizing the electronic device's own output capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate alarm device and recognition signal are used to prevent theft, then theft prevention function is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the alarm device function with the electronic device itself. The processor of the electronic device performs both the recognition signal generation and alarm output functions, eliminating the need for a separate alarm device. This merging reduces circuit complexity while maintaining theft prevention effectiveness.
Solution Approach 2:
The electronic device's processor is made multi-functional by enabling it to perform both identification (recognition signal processing) and alarm output functions. The existing hardware resources of the electronic device are utilized for theft prevention, avoiding additional dedicated components and reducing overall system complexity.
2Reliability
If a separate alarm device is used to output alarm, then theft indication is provided, but additional costs are incurred
Solution Approach 1:
The alarm output function is merged into the electronic device's existing alarm capabilities (such as speaker or notification system). By using the electronic device's own alarm resources rather than a separate alarm device, manufacturing costs are reduced while maintaining the ability to provide theft indication.
Solution Approach 2:
The electronic device serves itself by using its own processor and alarm output capabilities to detect theft and generate alarm signals. This self-service approach eliminates the need for separate dedicated components, reducing both manufacturing cost and system complexity.
