Endoscope Movable Board for Signal Integrity
Solution Overview
Problem
Conventional endoscope systems face challenges in securely connecting the image pickup module and the image pickup cable, which can lead to signal interference and mechanical stress, especially when external forces are applied during medical procedures.
Innovation Solution
The endoscope system incorporates a movable board with a curved surface that is freely displaceable in the optical axis direction, electrically connecting the image pickup module and the image pickup cable. This configuration ensures a secure and flexible connection, reducing the impact of external forces and maintaining signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connection structure is used to connect the image pickup module and cable, then mechanical strength is improved, but adaptability to external forces and flexibility are worsened
Solution Approach 1:
The patent employs a movable board that can displace along the optical axis in response to external forces, transforming the rigid connection into a dynamic system. This allows the connection structure to adapt its position and maintain mechanical strength while accommodating external forces during endoscopic procedures.
Solution Approach 2:
The movable board changes its position parameter (displacement along the optical axis) in response to external forces. This parameter change enables the connection to maintain both mechanical strength and adaptability, as the board moves to compensate for applied forces while remaining electrically connected.
2Reliability
If the image pickup module and cable are securely connected, then signal integrity is improved, but mechanical stress and interference from external forces are worsened
Solution Approach 1:
The movable board serves as an intermediary component between the image pickup module and the cable. It mediates the transmission of electrical signals while physically isolating the connection from direct mechanical stress, allowing signal integrity to be maintained despite external forces applied during procedures.
Solution Approach 2:
By making the connection dynamic through the movable board's displacement capability, the system maintains secure electrical connection for signal integrity while the board's movement absorbs and distributes mechanical stress, preventing stress concentration that could cause interference or failure.
3Ease of manufacture
If a fixed connection structure is used, then assembly simplicity is improved, but adaptability to external forces and signal stability are worsened
Solution Approach 1:
The movable board provides a simple yet effective dynamic connection mechanism that maintains signal stability during procedures. The board's ability to displace along the optical axis ensures continuous electrical connection while adapting to external forces, achieving both assembly simplicity and signal stability.

AI summary
An endoscope includes an image pickup module having an optical axis that defines a visual field direction and provided with an electric contact, a cable that is disposed on a proximal end side of the image pickup module and transfers an image pickup signal generated by the image pickup module, a channel provided beside the image pickup module, and a movable board electrically connecting the electric contact and the cable to transfer the image pickup signal and including a movable portion capable of forming a curved surface that is freely displaceable in an optical axis direction. The movable portion of the movable board is arranged at a position where a distance between the curved surface and the channel is longer than a distance between the curved surface and the optical axis.
