Solution Overview
Problem
Existing gas laser systems face difficulties in maintaining a laser gas state during power failures, leading to challenges in omitting part of the gas exchanging process at reactivation, which prolongs the time to resume discharging.
Innovation Solution
A gas laser system with a power storage unit and control unit that detects power reduction, allowing the gas supply and discharge valves to be sealed, maintaining the gas flow path in a sealed state during power failures, thus preserving the laser gas state for quick reactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the laser oscillator is stopped normally and gas exchange is performed, then the laser gas state is maintained for next activation, but when power failure occurs the stop operation cannot be performed normally and gas exchange process cannot be omitted
Solution Approach 1:
The control unit is configured to detect power failure and automatically seal the gas flow path before the gas exchange process would normally occur. This preliminary sealing action prevents the loss of laser gas state during power failure, allowing the system to maintain its operational condition without requiring full gas exchange upon reactivation.
Solution Approach 2:
A power storage unit (uninterruptible power source) is introduced as an intermediary between the main power supply and the laser oscillator. This intermediary component provides backup power during power failures, enabling the control unit to detect the failure condition and seal the gas flow path, thereby maintaining the laser gas state.
2Reliability
If power storage unit and control unit are added to detect power reduction and seal gas flow path, then laser gas state is maintained during power failures, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it controls the gas supply and discharge unit during normal operation, detects power failure conditions, and automatically seals the gas flow path when power failure is detected. By consolidating these functions into a single control unit, the system achieves reliable laser gas state maintenance while minimizing the increase in device complexity.
Solution Approach 2:
The system automatically detects power failure and seals the gas flow path without requiring manual intervention. The control unit monitors the power supply status and autonomously takes corrective action by controlling the gas supply and discharge unit to seal the flow path, thereby maintaining the laser gas state through self-service operation.
3Loss of time
If gas supply and discharge unit is controlled to seal gas flow path during power failure, then activation time is reduced upon power recovery, but control precision requirements increase
Solution Approach 1:
The power reduction detection unit continuously monitors the power supply status and provides feedback to the control unit. When the detected power level indicates a power failure condition, the control unit receives this feedback and automatically controls the gas supply and discharge unit to seal the gas flow path, thereby maintaining the laser gas state and reducing activation time upon power recovery.
