Proximity-Based Mobile Machine Control for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices used to control machines face 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 determines if a user mobile device is within a defined zone, displays authorized control buttons on the device's screen, and sends control signals only when the user interacts with these buttons, ensuring authorized proximity and interaction.
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 reliability deteriorate due to unauthorized access and potential misuse
Solution Approach 1:
The patent introduces a proximity detection system as an intermediary between the user and machine control. This intermediary verifies the user's physical proximity to the machine before allowing control, acting as a security gatekeeper that enables remote operation while preventing unauthorized access from distant locations
Solution Approach 2:
The system changes the parameter of access control from purely remote to proximity-based. By requiring the mobile device to detect that the user is within a specific distance threshold of the machine, the system modifies the control parameters to include location verification, thereby maintaining ease of operation for authorized users while blocking unauthorized remote access
2Adaptability or versatility
If users can control machines from any location, then adaptability is improved, but harmful factors increase due to accidental or intentional misuse
Solution Approach 1:
The system applies preliminary anti-action by preventing harmful control actions before they can occur. The proximity verification mechanism proactively blocks control signals from mobile devices that are not physically near the machine, thereby preventing both accidental and intentional misuse before it can affect the machine
Solution Approach 2:
The proximity detection system serves as a mediator that filters control requests. It allows legitimate local operations while blocking potentially harmful remote commands, thus enabling adaptability for authorized users while reducing the risk of misuse from unauthorized locations

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.
