Proximity-Based Mobile Machine Control for Authorized Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of mobile devices to control physical devices poses security issues due to unauthorized access and potential misuse, as users can accidentally or intentionally control machines remotely without proper authorization.
Innovation Solution
A proximity-enabled machine control system that uses a user mobile device with a processor and touch-sensitive screen to determine proximity to a machine, display control buttons only when authorized, and send machine control signals upon user activation, thereby ensuring controlled access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices are used to control machines remotely, then ease of operation is improved, but security and authorization control deteriorate
Solution Approach 1:
The patent introduces a proximity detection intermediary (GPS, RFID, or camera-based system) that mediates between the mobile device and the machine control system. This intermediary verifies the user's physical proximity to the machine before enabling control, thus maintaining ease of remote operation while restoring authorization control through proximity verification.
2Adaptability or versatility
If users can control machines from any location, then adaptability is improved, but harmful factors increase
Solution Approach 1:
The patent applies preliminary anti-action by implementing proximity verification before control is granted. The system proactively prevents unauthorized control by checking whether the user is physically near the machine before allowing any control operations, thus countering potential harmful effects before they can occur.
3Reliability
If proximity verification is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent leverages the multi-functionality of mobile devices by using their existing cameras, GPS, or RFID capabilities for proximity detection. Instead of adding dedicated complexity, the system repurposes existing universal components of the mobile device to provide proximity verification, thus improving security without significantly increasing device complexity.

AI summary
A proximity-enabled machine control system includes a user mobile device having a processor, a touch sensitive screen coupled to the processor, and non-transitory computer readable media with code segments executable on the processor for: (a) determining if the user mobile device is within a proximity zone of a machine; (b) displaying on the touch sensitive screen at least one machine control button for the machine; (c) detecting an activation of the at least one machine control button by the user; and (d) developing a machine control signal to control the machine.
