Solution Overview
Problem
Existing cable connection structures for endoscope systems are costly and lack flexibility due to the use of multiple components like circuit boards and three-dimensional wiring boards, which increase parts and wiring costs, and embedded members that reduce wire flexibility.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate components (circuit board, three-dimensional wiring board, embedded member) are used to connect the cable to the electronic component, then the electrical connection reliability is improved, but the parts cost and wiring cost increase
Solution Approach 1:
The patent removes intermediate components (circuit board, three-dimensional wiring board, embedded member) from the connection structure, directly connecting the cable core wires to the electronic component electrodes. This extraction eliminates unnecessary parts while maintaining electrical connection reliability through direct soldering of core wires to electrodes.
Solution Approach 2:
The patent merges the cable connection function directly with the electronic component by eliminating intermediate components. The cable is integrated directly onto the electronic component surface, combining what were previously separate elements into a unified structure that reduces parts count and cost.
2Stability of the object's composition
If an embedded member is used to secure the cable to the electronic component, then the connection stability is improved, but the cable flexibility is reduced
Solution Approach 1:
The patent removes the embedded member from the connection structure, eliminating the source of flexibility restriction. The cable is secured through alternative means that do not involve rigid embedding, allowing the cable to maintain its natural flexibility while achieving stable connection through direct mounting and soldering.
3Reliability
If multiple intermediate components are used in the cable connection structure, then the electrical integrity is maintained, but the manufacturing complexity increases
Solution Approach 1:
The patent extracts and removes intermediate components (circuit board, three-dimensional wiring board, embedded member) from the manufacturing process. This simplification maintains electrical integrity through direct core wire-to-electrode soldering while significantly reducing manufacturing complexity and assembly steps.
Solution Approach 2:
Instead of building up the connection structure through multiple intermediate components from the cable outward, the patent inverts the approach by directly mounting the cable onto the electronic component and soldering the core wires to the electrodes, simplifying the manufacturing sequence.
