Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopes require manual operation of the bendable section during emergencies, which can be challenging for doctors, and existing power-assisted endoscopes face issues with accurate power transmission and stability, particularly in cases of overcurrent or overvoltage.
Innovation Solution
A power providing device with a novel structure that includes a power source, power transmission part, and a stopper to restrict the motion of the power providing part, allowing for accurate and stable power delivery to the endoscope's bendable section, enabling precise control of the bending motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of the control knob is used to control the bending motion, then the doctor can directly control the endoscope, but the doctor cannot focus on both operating the knob and handling emergency situations, resulting in inaccurate bending motion
Solution Approach 1:
The endoscope system performs bending motion automatically using a motor-driven power transmission mechanism, eliminating the need for manual knob operation. The system serves itself by converting control signals into automatic bending actions, freeing the doctor from manual manipulation while maintaining precise control during emergencies.
Solution Approach 2:
The manual mechanical cord and control knob system is replaced with an automated motor-driven power transmission system. The mechanical connection between the control knob and bendable section is substituted with an electric motor, drive shaft, and power transmission part that automatically execute bending motions based on control signals.
2Reliability
If power is transmitted to the endoscope to enable automatic bending motion, then the doctor can focus on emergency situations, but the power transmission may be inaccurate under unexpected conditions such as overcurrent or overvoltage, resulting in unstable bending control
Solution Approach 1:
A stopper mechanism is pre-installed in the power transmission path to physically limit the maximum displacement of the power providing part. This cushioning mechanism prevents excessive bending motion that could occur during power anomalies, ensuring the bendable section remains within a predetermined safe range even when power transmission becomes unstable.
Solution Approach 2:
The stopper acts as an intermediary mechanical element between the power source and the bendable section. It mediates the power transmission by allowing normal operation while blocking excessive motion during abnormal conditions, thus protecting the system from power-related precision errors.
3Reliability
If a stopper is added to restrict the motion range of the power providing part, then the bending motion can be kept within a predetermined range for safety, but the device complexity increases
Solution Approach 1:
The power transmission system is segmented into distinct functional components: the power source, power transmission part, power providing part, and stopper mechanism. This segmentation allows the stopper to be added as a separate, modular element that independently provides safety functionality without requiring a complete redesign of the entire system.
