Engineering Contradiction Analysis
1Volume of moving object
If a conventional endoscopic image capturing assembly is used, then the image capturing function is achieved, but the size of the assembly is bulky, preventing further reduction of incision size
Solution Approach 1:
The conducting track is formed from the first surface to the second surface of the holder in a direction substantially perpendicular to the first surface, utilizing the third dimension (depth/thickness) of the holder for electrical connection. This vertical arrangement through the holder's thickness enables compact integration of electrical components without increasing the lateral footprint of the image capturing assembly.
Solution Approach 2:
The holder integrates multiple functions: it provides mechanical support for mounting the image sensing device, serves as a substrate for forming conducting tracks, and acts as a mounting surface for cable terminals. By combining these functions into a single holder structure, the overall assembly size is reduced while maintaining all necessary image capturing functions.
2Volume of moving object
If the image capturing assembly size is reduced, then smaller incisions are enabled, but the electrical connection between components becomes more difficult to achieve
Solution Approach 1:
The conducting track extends from the first surface to the second surface of the holder in a direction substantially perpendicular to the first surface, utilizing the vertical dimension of the holder for electrical connection. This three-dimensional routing of electrical connections allows compact lateral arrangement of components while maintaining reliable electrical pathways through the holder's thickness.
Solution Approach 2:
The holder acts as an intermediary structure that facilitates electrical connection between the image sensing device and cable terminals. The conducting track formed on the holder provides a built-in electrical pathway, serving as an integrated mediator that eliminates the need for separate external wiring and simplifies the manufacturing process.
