Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding systems lack flexibility in defining and modifying trigger conditions for sensors and process actuators connected to the welding power source, limiting their adaptability to periodically changing process parameters.
Innovation Solution
A user interface integrated with the welding power source allows for flexible definition and modification of trigger conditions for various sensors and process actuators, enabling them to be synchronized with periodically changing process parameters through a connection, which can be wired or wireless, and includes features like pre-triggering to compensate for delays.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional welding systems use predefined trigger conditions for sensors and process actuators, then the system structure remains simple, but the adaptability to different welding processes and parameters is limited
Solution Approach 1:
The trigger conditions are made dynamically configurable through a user interface, allowing operators to adjust trigger parameters, delay times, and selection criteria based on specific welding process requirements. This transforms the static predefined trigger system into a dynamic adaptive system without requiring complex hardware modifications.
Solution Approach 2:
The system allows changing of trigger condition parameters including trigger level, delay time, and sensor/actuator selection through the user interface. By enabling parameter modification rather than requiring hardware reconfiguration, the system achieves high adaptability while maintaining structural simplicity.
2Manufacturing precision
If trigger conditions are predefined and fixed, then the system is easy to operate, but the precision of synchronization with process parameters cannot be optimized
Solution Approach 1:
The system provides pre-configured trigger condition templates and default settings that can be selected through the user interface. This allows operators to quickly set up synchronization without complex manual configuration, while still enabling fine-tuning for high precision when needed. The preliminary setup reduces operational complexity while maintaining precision capabilities.
Solution Approach 2:
The system incorporates feedback mechanisms that allow operators to monitor the synchronization performance and adjust trigger conditions accordingly. Through the user interface, operators can observe process parameters and refine trigger timing to achieve optimal synchronization precision while maintaining ease of operation through iterative adjustment.
3Productivity
If multiple sensors and actuators are connected with flexible trigger conditions, then the monitoring and control capabilities are enhanced, but the device complexity increases
Solution Approach 1:
The user interface serves as a universal configuration platform that can manage multiple sensors and actuators through a single system. Rather than requiring separate configuration systems for each device, the universal interface consolidates trigger condition management, reducing operational complexity despite supporting multiple devices. This multi-functional approach enhances monitoring and control capabilities while maintaining manageable system complexity.
