Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a base body or three-dimensional wiring substrate is not provided and the coaxial cable is directly soldered to the image-sensing device, then the device complexity is reduced, but the ease of manufacture deteriorates due to high difficulty in separating and connecting internal and external conductors
Solution Approach 1:
The patent introduces a support as an intermediary component between the image-sensing device and the coaxial cable. This support includes a guide structure that receives the internal conductor and facilitates its connection to the image-sensing terminal, while also providing a mounting surface for the external conductor. This mediator simplifies the connection operation by organizing the conductors in a structured manner rather than requiring direct soldering of separated conductors to the tiny image-sensing device.
2Adaptability or versatility
If an ultrafine electrical cable is used to reduce the endoscope diameter, then the adaptability is improved, but the reliability deteriorates due to increased noise reception in the transmission path
Solution Approach 1:
The support acts as an intermediary that structurally organizes the internal and external conductors of the coaxial cable, maintaining their coaxial relationship and shielding effectiveness. By providing a guide for the internal conductor and a mounting surface for the external conductor, the support ensures proper conductor arrangement that minimizes noise interference while allowing the use of ultrafine cables for small-diameter endoscopes.
3Manufacturing precision
If the internal conductor and external conductor are separated for connection to the image-sensing device, then the manufacturing precision can be improved, but the productivity deteriorates due to complex connection operations
Solution Approach 1:
The support is prepared in advance with a guide structure and mounting surfaces positioned at predetermined locations. The internal conductor is inserted into the guide, and the external conductor is mounted on the support surface before the connection to the image-sensing device. This preliminary arrangement of conductors on the support simplifies the final connection operation and improves manufacturing efficiency while maintaining precision.
Solution Approach 2:
The connection structure is segmented into multiple functional components: the support with its guide for the internal conductor, the mounting surface for the external conductor, and the connection interface for the image-sensing device. This segmentation allows each component to be prepared and positioned independently, facilitating more efficient assembly while maintaining alignment precision.
