Welder Theft Protection via Electronic Link Key Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding and generator equipment are frequently targeted for theft due to their high value, and existing security measures are often ineffective in preventing theft, especially when the equipment is left at job sites where power may not be readily available.
Innovation Solution
A welding device with an activation system that electronically pairs with an activation device, requiring verification of an authorization code and generating a link key for the motor or energy storage device to function, ensuring that the equipment cannot be operated without proper authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures are used to secure welding equipment, then some theft deterrence is provided, but thieves can still overcome these measures and steal the equipment
Solution Approach 1:
The patent replaces traditional mechanical security measures (locks, chains, physical barriers) with an electronic authentication system. The welding device uses electronic signals, authorization codes, and link keys to control operation, substituting physical security mechanisms with electronic verification processes that are harder to bypass.
Solution Approach 2:
The patent introduces an intermediary authentication process between the user and the welding device operation. The system requires verification through authorization codes and link keys transmitted via communication interfaces, creating a mediatory layer that validates user identity before allowing device operation, thereby enhancing security beyond direct mechanical access control.
2Reliability
If the welding device requires electronic pairing and authorization verification, then unauthorized use is prevented, but the operation process becomes more complex and time-consuming
Solution Approach 1:
The patent implements preliminary pairing between the welding device and activation devices before actual use. During this initial setup, link keys are generated and stored, and authorization codes are established. This preliminary action creates a reusable authentication mechanism that speeds up subsequent operations, as users don't need to perform full verification each time they use the device.
Solution Approach 2:
The patent creates digital copies of authentication credentials (link keys, authorization codes) that can be stored and reused. Instead of requiring physical presence of original authorization materials, the system uses replicated digital credentials that can be electronically verified, maintaining security while improving operational convenience.
Data Source
AI summary
A system and method are disclosed for securing a welding device where functionality of the welding device can be limited or restricted due to an electronic signal between a lock component and an activation device. The activation device can be paired with the welding device, and in turn, the lock component, in which an electronic signal is communicated there between. Based upon whether the electronic signal is received by the lock component and the welding device, the lock device can be configured to de-activate or prevent a power supply (e.g., motor, generator, energy storage device, etc.) of the welding device from activating.
