Welding Controller Limited-Term Software Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding systems, such as the Miller Axcess®, require a return visit from a salesperson or technician to disable additional welding process options after a trial period, which is inconvenient and costly, as customers do not fully appreciate the capabilities of multi-process machines and lack a straightforward method to test features without permanent software removal.
Innovation Solution
Implementing a welding system with a controller that includes a limited-term welding program, which can be activated via a data port and terminated based on elapsed time, number of arc starts, or usage, allowing customers to test features like pulse or controlled short circuit processes for a fixed duration without requiring external intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a welding program is permanently installed on the welding system, then the customer can use the welding process indefinitely, but the customer cannot test the feature without committing to a purchase
Solution Approach 1:
The welding program is implemented with dynamic time-limited access control, where the program automatically becomes unavailable after a predetermined time period expires. This allows the system to transition from a permanently installed state to an automatically deactivated state, enabling customers to test features temporarily without permanent commitment.
Solution Approach 2:
The system pre-configures the welding program with an embedded timer that automatically terminates access after a predetermined period. This preliminary setup eliminates the need for subsequent manual intervention to disable the program, as the termination action is already prepared and executed automatically.
2Reliability
If a salesperson or technician returns to disable the welding program after a trial period, then the feature can be properly deactivated, but this adds cost and inconvenience
Solution Approach 1:
The welding program includes self-terminating functionality where the program automatically disables itself after the predetermined time period expires. This self-service mechanism eliminates the need for external intervention by a salesperson or technician, allowing the system to properly deactivate the feature autonomously.
Solution Approach 2:
The system pre-configures the welding program with an embedded timer that automatically terminates access after a predetermined period. This preliminary setup eliminates the need for subsequent manual intervention to disable the program, as the termination action is already prepared and executed automatically.
3Productivity
If the welding program is left permanently enabled, then the customer has continuous access to the feature, but the customer may purchase without fully appreciating the capability
Solution Approach 1:
The welding program implements dynamic access control that transitions from enabled to disabled state after a predetermined time period. This dynamic behavior ensures customers experience the feature temporarily to understand its capabilities, rather than having continuous unrestricted access that may lead to uninformed purchasing decisions.
Data Source
AI summary
A method and apparatus for welding uses a power circuit and a controller connected to the power circuit. The controller included a welding program having a limited term. The program may be part of a system, or a stand alone program. The controller has a data port and the welding program and/or an authorization is received by the controller on the data port in one embodiment. The welding program includes a limited time module, a limited time in use module, a limited arc start module, a controlled short circuit program, and/or a pulse program in various embodiments. A second welding program, without a limited term module, may be provided.
