Wireless Local Servicing via Proximity-Verified Mobile Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Technicians with electronic servicing tools cannot perform local servicing tasks on machines without a wired connection, and even with a wired connection, they face numerous steps to initiate servicing due to lack of proximity recognition.
Innovation Solution
A method and system that enable a mobile troubleshooting device to access a machine's network manager via a personal area network (PAN) for local troubleshooting, allowing the device to perform operations responsive to operator inputs after successful pairing and connection, using short-wavelength UHF radio waves like Bluetooth, and providing local troubleshooting functionality based on authorized rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired connection is used to enable local servicing, then access to local servicing capabilities is achieved, but device complexity and number of steps increase
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The mobile device establishes a wireless connection to the machine's communication interface, eliminating the need for physical cable connections and associated setup steps while maintaining reliable access to local servicing capabilities.
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the mobile device and the machine's control system. This intermediary enables wireless data exchange and servicing capabilities without requiring direct physical connection, simplifying the interaction process.
2Ease of operation
If wireless connection is used without wired connection, then ease of operation improves, but access to local servicing capabilities is lost
Solution Approach 1:
The patent substitutes the mechanical wired connection with a wireless communication system that provides equivalent or superior functionality. The mobile device uses wireless protocols to communicate with the machine, achieving both ease of operation and access to local servicing capabilities simultaneously.
3Measurement precision
If proximity recognition is implemented, then local servicing accuracy improves, but device complexity increases
Solution Approach 1:
The patent uses the machine's existing communication interface as an intermediary to verify proximity. The mobile device authenticates with the machine's communication interface, which confirms the device is in proper proximity to perform local servicing, without requiring separate complex proximity detection hardware.
