Solution Overview
Problem
Existing systems fail to accurately determine the state of light emitting units in light source devices connected to endoscopes, leading to potential inefficiencies and safety concerns.
Innovation Solution
A system comprising a light source device with light emitting units and sensors that measure characteristic values, and a processor to perform light emission control and determine the state of the units based on these values, even when the endoscope is not connected or in a non-use state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the endoscope is connected to the light source device, then light can be supplied to the endoscope for examination, but the state of the light emitting unit cannot be determined when the endoscope is not connected or in non-use state
Solution Approach 1:
The system performs light emission control and state determination in advance when the endoscope is not connected or in non-use state. The processor causes the light emitting unit to emit light under controlled conditions, acquires characteristic values from the sensor, and determines the state before actual examination use, ensuring reliability is verified beforehand.
2Reliability
If light emission control is performed continuously, then the state of the light emitting unit can be monitored, but energy is wasted when the endoscope is not connected or in non-use state
Solution Approach 1:
The system dynamically adjusts light emission control based on the operational state. Light emission control is performed selectively when the endoscope is not connected or in non-use state, rather than continuously. The processor determines the appropriate timing for state verification, optimizing the balance between reliability monitoring and energy conservation.

AI summary
A system includes: a light source device including a light emitting unit and a sensor that measures a characteristic value of the light emitting unit, and configured to supply light emitted from the light emitting unit to an endoscope; and a processor. The processor is configured to: in a first case where the endoscope is not connected to the light source device, or in a second case where the endoscope is connected to the light source device and is in a non-use state, perform light emission control of causing the light emitting unit to emit light under a first condition; acquire, from the sensor, the characteristic value of the light emitting unit that has emitted light under the light emission control; and determine a state of the light emitting unit based on the characteristic value and a reference value.
