Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exothermic welding processes require operators to be in close proximity to the reaction, posing safety risks due to the rapid and intense nature of the exothermic reaction initiation.
Innovation Solution
A controller system with a battery, cable, and igniter, controlled by a portable electronic device, that allows for wireless ignition initiation from a safe distance, featuring safety features like distance determination and pairing protocols to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flint igniter is used to initiate the exothermic reaction, then the weld material can be ignited effectively, but the operator must be in close proximity to the mold which places them in close proximity to the hazardous reaction
Solution Approach 1:
The patent introduces a controller as an intermediary device between the operator and the igniter. The controller receives wireless commands from a portable electronic device and activates the igniter remotely, allowing the operator to initiate the exothermic reaction without being in close proximity to the mold, thus resolving the contradiction between effective ignition and operator safety
Solution Approach 2:
The patent replaces the manual mechanical flint igniter operation with an electronic control system. The wireless module and controller substitute for direct manual intervention, enabling remote activation of the igniter through electronic signals while maintaining reliable ignition of the weld material
2Object-affected harmful factors
If remote wireless control is implemented, then operator safety is improved by increasing distance from the reaction, but the system complexity increases due to additional electronic components
Solution Approach 1:
The controller serves multiple functions: it acts as a wireless receiver, a signal processor, an ignition activator, and a safety monitoring device. By consolidating these functions into a single multi-functional device, the patent reduces overall system complexity while maintaining operator safety benefits
Solution Approach 2:
The system uses the operator's existing portable electronic device (smartphone, tablet, or radio) to provide wireless control capability. This self-service approach leverages equipment the operator already possesses, eliminating the need for a complex dedicated wireless interface and reducing overall system complexity
