Proximity-Based Device Pairing for Automatic Activation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and devices that can automatically activate and deactivate smart devices when they are misplaced, lost, or misappropriated to prevent unauthorized use, as individuals often lose or misplace valuable items like mobile devices, keys, and wallets, which are increasingly connected via wireless protocols.
Innovation Solution
The solution involves pairing devices using short-range wireless communication protocols such as RFID, NFC, or Bluetooth, where a device remains active only when in close proximity to the user and deactivates when out of range, with optional features like readable indicia for activation via image capture and alert modules for user notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smart devices are configured to be always active for convenient use, then ease of operation is improved, but security against unauthorized use deteriorates
Solution Approach 1:
The device dynamically changes its operational state between active and inactive based on real-time proximity detection. When the paired device is detected within the threshold distance, the smart device transitions to an active state for normal use. When the paired device moves beyond the threshold, the smart device automatically transitions to an inactive state, preventing unauthorized use while maintaining convenience during legitimate use.
Solution Approach 2:
The system continuously monitors the proximity status between paired devices and uses this feedback to control the active/inactive state. The proximity sensor provides real-time feedback about the distance to the paired device, and this feedback loop enables automatic state transitions that balance security and usability without requiring manual user intervention.
2Object-affected harmful factors
If automated deactivation is implemented when devices are out of range, then security is improved, but device complexity increases
Solution Approach 1:
The smart device autonomously manages its own security state based on proximity detection without requiring external control systems or complex infrastructure. The device self-monitors its environment, automatically transitions between states, and manages its own security, thereby reducing overall system complexity while maintaining robust security functionality.
Solution Approach 2:
The patent introduces a paired device as an intermediary that mediates the security state of the smart device. Instead of requiring complex authentication systems or continuous user verification, the paired device serves as a simple presence indicator. When the intermediary (paired device) is present within threshold distance, the smart device remains active; when absent, it automatically deactivates, simplifying the security architecture.
3Object-affected harmful factors
If proximity-based activation is used, then security against loss is improved, but loss of time for pairing setup occurs
Solution Approach 1:
The pairing process is performed in advance during a controlled setup phase, establishing the trusted relationship between devices before they are needed for security-critical operations. Once paired, the devices automatically recognize each other through their unique identifiers, eliminating the need for repeated pairing procedures and reducing setup time for future security activations.
Solution Approach 2:
The system uses unique device identifiers and cryptographic credentials that are pre-configured and copied between devices during the initial pairing process. These digital credentials serve as secure copies that enable automatic mutual authentication without requiring physical presence or manual verification during subsequent security activations, thereby minimizing time loss while maintaining security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances security by ensuring that a device can only be active when in the user's possession or range, providing an additional layer of protection against unauthorized use by automatically deactivating when not in use.
Implementation Method 1
the paired devices may be configured to communicate via short-range wireless communication, such as, but not limited to, Radio Frequency Identifier (RFID) operating in the 433 MHz or 865-868 MHz frequency band, Near Field Communication (NFC) operating in the 13.56 MHz frequency band, BLUETOOTH operating in the 2400 and 2483.5 MHz or some derivate form thereof

AI summary
A device/object is paired to one or more communication devices for the purpose of activating and/or deactivating the device/object. Such activation of the device/object requires that the paired devices be in concurrent possession of the user (i.e., within a specified range of the user) and that, while in concurrent possession of the user, communicate information from the device/object to the communication device. Thus, the invention provides for additional security, in that two or more devices must in the possession of the user (or within the specified range of the user), and communicating with one another, in order for one of the paired devices to be in activated state.
