Engineering Contradiction Analysis
1Volume of moving object
If a bulky image capturing assembly is used in conventional endoscopes, then the image capturing function is adequate, but the incision size cannot be reduced and insertion capability is limited
Solution Approach 1:
The patent merges the cable and circuit board into a single integrated structure where the cable serves dual purposes: providing electrical connection and serving as the circuit board substrate. This consolidation eliminates the need for separate cable routing and circuit board mounting, significantly reducing the overall endoscope volume while maintaining adequate image capturing functionality
Solution Approach 2:
The patent implements nesting by placing the conductive hole structure within the cable itself, and by mounting the surface mounted device directly onto the circuit board which is integrated with the cable. This nested arrangement allows multiple functional components to occupy the same spatial envelope, reducing the external dimensions of the endoscope to enable smaller incisions
2Device complexity
If traditional cable and circuit board connection methods are used, then electrical connection is reliable, but the structure is bulky and space-consuming
Solution Approach 1:
The patent combines the cable and circuit board into a single integrated component, eliminating the need for separate connection structures. The cable becomes the circuit board substrate, and conductive holes are formed directly within the cable material, creating a unified structure that reduces assembly complexity and volume
Solution Approach 2:
The patent extracts the electrical connection function from the traditional cable-circuit board interface and integrates it directly into the cable structure itself. By forming conductive hole structures within the cable material and mounting electrical connecting components directly to the cable, the invention eliminates the need for separate connection mechanisms, thereby reducing the overall assembly size
