Solution Overview
Problem
Wireless communication technologies face challenges in harsh environments such as welding locations due to noise and security concerns, especially when extending cables over long distances or in multiple remote welding applications, where existing systems struggle with reliable and secure communication between industrial equipment.
Innovation Solution
A system comprising a master node device with communication and control circuitry that facilitates both long-range and short-range wireless communication links, enabling secure association of welding-related devices within a local wireless network, with a synchronization mechanism for manual initiation and prioritization, and a method for establishing and managing these networks to ensure reliable and secure data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If long cables are extended to remote welding locations, then power supply is achieved, but the system becomes cumbersome and difficult to operate
Solution Approach 1:
The patent replaces the mechanical cable-based power and communication system with a wireless communication system. The welding-related devices communicate wirelessly with the master node device, eliminating the need for long physical cables while maintaining system functionality. This substitution directly addresses the cumbersome nature of extended cables while preserving power supply and control capabilities.
2Ease of operation
If wireless communication is used in harsh welding environments, then cable complexity is reduced, but communication reliability deteriorates due to noise
Solution Approach 1:
The master node device serves as an intermediary between the welding-related devices and the noise-prone wireless environment. It receives wireless communications from welding devices, processes the signals, and communicates with the power supply unit, isolating the critical control functions from direct exposure to environmental noise and interference.
Solution Approach 2:
The system employs parameter changes in the communication protocol to adapt to harsh environments. By adjusting communication parameters such as data rate, modulation scheme, and error correction codes based on environmental conditions, the system maintains reliable communication despite noise and interference in welding locations.
3Ease of operation
If wireless communication is implemented in industrial environments, then cable management is simplified, but security vulnerabilities increase
Solution Approach 1:
The master node device acts as a security intermediary that mediates all wireless communications. It authenticates welding-related devices before allowing them to join the network, encrypts data transmissions, and filters unauthorized access attempts, thereby protecting the system from security threats while maintaining wireless convenience.
4Productivity
If multiple remote welding locations are served simultaneously, then productivity increases, but cable management becomes increasingly complex
Solution Approach 1:
The wireless communication system replaces the mechanical cable infrastructure that would be required to serve multiple remote welding locations. Each welding device communicates independently via wireless signals, eliminating the need for a complex web of cables running between the power supply unit and multiple remote locations, thereby enabling high productivity without increased complexity.
