Wireless Laser Marker Disable System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser markers require users to physically interact with them to disable operation, which can be inconvenient and disrupt the installation position, increasing user workload.
Innovation Solution
A laser marker system that includes a wireless communicator to receive an enabled time, a measuring circuit to track elapsed time, and a disabling circuit that automatically disables the laser marker when the elapsed time reaches the enabled time, eliminating the need for user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a key switch with key plate is used to disable the laser marker, then theft can be deterred, but the user must physically move to and touch the laser marker to disable it, which is inconvenient and may change installation position
Solution Approach 1:
The patent replaces the mechanical key switch system with a wireless communication system. The external device transmits disable commands wirelessly to the laser marker, eliminating the need for physical contact or movement to the device. This substitution maintains security functionality while dramatically improving user convenience.
Solution Approach 2:
The patent introduces an external device as an intermediary between the user and the laser marker. This intermediary handles the disable operation remotely, allowing the user to disable the laser marker without directly interacting with it. The external device acts as a mediator that preserves both security and convenience.
2Ease of operation
If the laser marker is disabled by removing the key plate, then the operation is stopped, but the installation position changes requiring repositioning
Solution Approach 1:
The wireless disable mechanism eliminates the need for physical removal of components. The laser marker remains in its installation position while being disabled through wireless communication, completely avoiding the repositioning issue that occurs with mechanical key plate removal.
Solution Approach 2:
The laser marker autonomously processes the disable command received via wireless communication without requiring physical manipulation. The system self-adjusts its operational state while maintaining its physical position, eliminating the need for user repositioning actions.
3Ease of operation
If wireless communication with external device is implemented, then remote disabling is achieved, but device complexity increases
Solution Approach 1:
The laser marker's existing wireless communication capability, originally designed for other functions, is extended to handle the disable operation. This multi-functional use of the wireless module avoids adding dedicated hardware for disabling, thereby minimizing the increase in device complexity while achieving remote disable functionality.

AI summary
A laser marker according to one aspect of the present disclosure includes: a laser emitter; an information reception circuit; a measuring circuit; and a disabling circuit. The measuring circuit starts to measure an elapsed time in response to the information reception circuit receiving an enabled time. The disabling circuit disables the laser marker for operating in response to a length of the elapsed time reaching or having reached a length of the enabled time.
