Radiation Source Assembly Power Interlock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid treatment systems pose safety risks during lamp servicing due to the potential for ultraviolet radiation exposure when power is not properly disconnected before removal, leading to occupational health hazards.
Innovation Solution
A radiation source assembly configuration that requires power disconnection before removal, featuring a two-step operation with a locking mechanism ensuring the radiation source is secured within the reactor port until the power is disconnected, and a visual indicator to confirm power status, preventing accidental exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the radiation source assembly allows removal without power disconnection, then ease of operation is improved, but safety deteriorates due to ultraviolet radiation exposure risk
Solution Approach 1:
The system performs preliminary action by automatically disconnecting power to the radiation source before allowing removal of the assembly. The control system detects removal intent and preemptively cuts power, ensuring safety before the actual removal action occurs.
Solution Approach 2:
The system uses feedback from sensors that detect the position and state of the radiation source assembly to automatically control power disconnection. When the assembly is detected to be in a removable state, the system feedback-controls the power supply to disconnect it.
2Object-affected harmful factors
If a locking mechanism requiring power disconnection is implemented, then safety is improved, but device complexity increases
Solution Approach 1:
The patent merges the power disconnection function with the mechanical removal mechanism into a single integrated system. The control system combines electrical power control with mechanical sensing, eliminating the need for separate locking mechanisms while achieving the same safety outcome.
Solution Approach 2:
The system performs self-service by automatically detecting when the radiation source assembly is being removed and autonomously disconnecting power without requiring manual intervention. The sensors and control system work together to automatically ensure safety.
