Endoscopic Camera Support Tube with Rotating Fixing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems for monitoring the inside of a body face issues with foreign substance contamination leading to electric connection failures and difficulty in achieving strong joins between camera units and cables, particularly due to the characteristics of communication cables, which affect the reliability and usability of the system.
Innovation Solution
A camera system comprising a support tube inserted into the body with an imaging unit that joins with the support tube, a cable connected to the imaging unit for external control, and a fixing tool to secure the support tube to the body surface, allowing for adjustable positioning and orientation of the imaging unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the needle-like connector electrode is directly inserted into the abdominal wall and the connector electrode and the camera join with each other in the body, then the camera system can be installed, but foreign substances may be mixed into the joining portion causing electric connection failure
Solution Approach 1:
The patent introduces a support tube as an intermediary component between the abdominal wall and the camera unit. The support tube provides a protected pathway for inserting the camera system, preventing foreign substances from contaminating the joining portion between the connector electrode and camera, thereby maintaining electric connection reliability while enabling installation.
2Ease of operation
If the communication cable is drawn out toward the outside of the body and fixed, then the camera unit can be accessed from outside, but it is difficult to obtain joining strength between the communication cable and the camera unit due to cable characteristics
Solution Approach 1:
The patent applies preliminary action by pre-securing the camera unit to the support tube before drawing out the communication cable. The camera unit is firmly attached to the support tube structure, which provides a stable anchor point. This preliminary securing ensures that when the cable is later manipulated and drawn out, the joining strength between the cable and camera unit is maintained through the structural support of the support tube.
3Ease of operation
If the communication cable is drawn out and fixed externally, then the system can be controlled from outside, but it is difficult to change the orientation of the camera unit from the outside of the body
Solution Approach 1:
The patent implements dynamics by making the support tube rotatable within the abdominal wall opening. The support tube can be rotated to change the orientation of the attached camera unit, while the communication cable remains externally accessible for control. This dynamic rotation capability allows the camera to be repositioned to different angles and directions, providing adaptability and versatility in viewing orientations while maintaining external controllability through the cable connection.
4Stability of the object's composition
If the camera unit is fixed in the body, then stability is achieved, but it cannot be adjusted to different positions and orientations
Solution Approach 1:
The patent applies dynamics by designing the support tube to be rotatable within the abdominal wall opening while maintaining a fixed connection between the camera unit and the support tube. This allows the camera unit to be stably mounted on the support tube structure, providing stability, while the support tube itself can be rotated to adjust the camera's orientation and viewing direction, achieving adaptability without compromising the fixed mounting stability.
