Solution Overview

Problem

The light output power of endoscopes decreases over time due to degradation effects such as fiber breaks, increasing connector losses, and contamination of optics, leading to insufficient luminosity at the distal end, which is costly and time-consuming to replace.

Innovation Solution

An endoscope apparatus with a measuring device that includes a light detection unit and processing unit to determine characteristic parameters of the lighting system, allowing for readjustment of the maximum luminosity to maintain a minimum required output power, thereby avoiding the need to replace affected elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the light output power is increased to compensate for degradation, then the luminosity at the distal end is maintained, but the risk of thermal damage to the subject increases

Engineering Contradiction:
Improveluminosity at distal endVSAvoidthermal damage risk
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where a measuring device continuously monitors the actual light output power at the distal end of the endoscope. The control unit receives this measurement data and dynamically adjusts the light source intensity to maintain the required luminosity while preventing excessive power output that could cause thermal damage. This closed-loop control ensures optimal illumination without exceeding safety thresholds.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes the operating parameters of the light source based on real-time measurements of optical element degradation. The control unit adjusts the light output power parameter according to the measured transmission characteristics, allowing the system to compensate for degradation effects while maintaining safety limits through continuous parameter optimization.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If optical elements are replaced to restore light output power, then the luminosity is restored, but the procedure becomes time-consuming and costly

Engineering Contradiction:
Improvelight output powerVSAvoidreplacement time
Core Design Contradiction:
Illumination intensityVSLoss of time

Solution Approach 1:

The patent enables the endoscope system to self-diagnose and self-compensate for degradation effects. The measuring device automatically detects changes in light transmission characteristics, and the control unit autonomously adjusts the light source intensity to maintain required output power. This eliminates the need for manual intervention, expert analysis, or physical replacement of optical elements, allowing continuous operation without downtime.

Inventive Principle:
Principle #25Self-service

3Illumination intensity

If the light source intensity is increased to compensate for fiber losses, then the distal end luminosity is maintained, but the energy consumption increases

Engineering Contradiction:
Improvedistal end luminosityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent employs dynamic adjustment of light source intensity based on real-time measurements of actual light transmission. Rather than continuously operating at maximum intensity to compensate for potential degradation, the system adapts the power level to match the actual transmission characteristics of the optical elements. This dynamic optimization maintains required luminosity while minimizing energy consumption by avoiding unnecessary over-compensation.

Inventive Principle:
Principle #15Dynamics
