Solution Overview
Problem
Existing endoscopes face difficulties in high-frequency surgeries where voltage pulses are transmitted to optical recording devices, leading to image deterioration or failure, particularly with CCD sensors, due to poor mechanical and electrical connections.
Innovation Solution
Incorporating an electrical insulating body, such as a rotatable ring made of plastic materials like PEEK, between the camera connection and the main body to prevent voltage pulses from reaching the optical recording device, ensuring a secure mechanical and electrical insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism with spring is used to mechanically fasten the optical recording device, then the device can be securely attached, but the mechanical connection properties deteriorate over time and the structure becomes complex
Solution Approach 1:
The patent removes the spring component from the locking mechanism, extracting the problematic element that caused deterioration over time. The simplified mechanism without the spring maintains secure attachment while eliminating the complexity and reliability issues associated with spring-based locking systems.
2Strength
If the main body is made electrically conductive for structural integrity, then the endoscope maintains mechanical strength, but voltage pulses are transmitted to the optical recording device causing image deterioration
Solution Approach 1:
The patent introduces an electrically insulating body as an intermediary component between the electrically conductive main body and the optical recording device. This mediator maintains the structural integrity of the conductive main body while blocking the transmission of voltage pulses to the optical recording device, thereby protecting against image deterioration.
3Reliability
If a complex locking mechanism with spring is used, then the optical recording device can be securely fastened, but the connection cannot be repeatedly released and re-established without impairment
Solution Approach 1:
By removing the spring component from the locking mechanism, the patent enables repeated attachment and detachment of the optical recording device without the mechanical connection properties deteriorating. The simplified mechanism allows for multiple cycles of connection and release while maintaining connection stability.
