Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding operators face inefficiencies due to the cumbersome nature of welding power supplies, which often require them to pause or stop welding operations to adjust parameters, especially when the welding location is distant or difficult to access.
Innovation Solution
A wireless sensor module integrated with clothing or footwear, equipped with motion and position sensors, that detects specific movements or positions to adjust welding parameters wirelessly, allowing operators to control power supply settings remotely without interrupting the welding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the welding power supply is positioned close to the welding operation for easy parameter adjustment, then the ease of operation is improved, but the welding system becomes less adaptable to remote or elevated welding locations
Solution Approach 1:
The patent replaces the mechanical approach of physically moving the welding operator to the power supply with a wireless communication system. The motion sensor detects operator movements and transmits parameter adjustment commands wirelessly to the power supply, eliminating the need for physical proximity while maintaining control capability.
Solution Approach 2:
The patent introduces a wireless communication system as an intermediary between the operator's motion and the power supply parameter adjustments. The motion sensor and wireless transmitter act as mediators that translate physical gestures into control commands without requiring direct mechanical connection or physical proximity.
2Ease of operation
If the welding operator moves to the power supply to adjust parameters, then the parameter adjustment capability is improved, but the productivity decreases due to welding operation interruptions
Solution Approach 1:
The patent enables continuous welding operations by allowing parameter adjustments to be made remotely without interrupting the welding process. The wireless motion-activated control system permits operators to adjust parameters on-the-fly while maintaining their position at the welding location, ensuring uninterrupted productive work.
Solution Approach 2:
The system allows operators to pre-program or quickly adjust welding parameters before beginning a welding task, and then modify them remotely during operation without pausing. This preliminary configuration combined with real-time remote adjustment capability maintains continuous productivity.
3Ease of operation
If the welding power supply is made compact for easy positioning, then the ease of operation is improved, but the device complexity increases due to integrated control systems
Solution Approach 1:
The patent extracts the control functionality from the main power supply unit and places it in a separate, portable wireless control module worn by the operator. This separation allows the power supply to remain compact while the complex control electronics are distributed to a different location, reducing the complexity burden on the main unit.

AI summary
In certain embodiments, a wireless sensor module includes a motion or position sensor configured to detect a defined motion or position of a welding operator. The wireless sensor module also includes memory circuitry configured to store the defined motion or position and an adjustment of an operating parameter of a welding system which corresponds to the defined motion or position. A processor of the wireless sensor module is coupled to the motion or position sensor and the memory circuitry, where the processor is configured to retrieve the adjustment of the operating parameter from the memory circuitry upon detection of the defined motion or position by the motion or position sensor. The wireless senor module further includes a wireless communication device coupled to the processor and configured to transmit the adjustment of the operating parameter to the welding system.
