Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If non-invasive visualization systems (ultrasound, optical devices) are used to identify structures, then visualization capability is improved, but integration with insertion devices for real-time tissue sensing is lacking
Solution Approach 1:
The patent combines multiple sensing modalities (optical transmitters, optical detectors, electrical impedance electrodes) and insertion device functions (injection, aspiration) into a single integrated apparatus. This merging allows real-time tissue characterization during insertion procedures without requiring separate external imaging systems, thereby reducing information loss while managing device complexity through functional integration.
2Measurement precision
If electrical impedance spectroscopy is used to detect tissue types, then tissue detection capability is improved, but real-time sensing during injection/aspiration without device manipulation is not achieved
Solution Approach 1:
The insertion device is designed with multi-functionality, incorporating both sensing capabilities (optical transmitters, optical detectors, electrical impedance electrodes) and therapeutic capabilities (injection through lumen, aspiration) within a single device. This allows the device to perform tissue detection, substance delivery, and fluid collection without requiring manipulation or exchange of devices, achieving real-time sensing while maintaining ease of operation.
3Manufacturing precision
If accurate real-time tissue type determination is implemented, then substance delivery accuracy is improved, but procedural complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where optical transmitters and detectors, along with electrical impedance electrodes, provide real-time tissue characterization data during insertion. This feedback enables accurate determination of tissue type, which then guides the injection or aspiration process to ensure precise substance delivery to the target tissue while avoiding non-target tissues, thereby improving accuracy without excessively increasing procedural complexity.

AI summary
A tissue detection and location identification apparatus can include, a first electrically conductive layer surrounding a lumen, an insulating layer surrounding the first electrically conductive layer, and a second electrically conductive layer circumferentially surrounding the insulating layer, where the insulating layer can electrically isolate the first electrically conductive layer from the second electrically conductive layer. A further insulating layer can surround the second electrically conductive layer. The first electrically conductive layer, the insulating layer, and the second electrically conductive layer can form a structure which has a first side and a second side disposed opposite to the first side with respect to the lumen, where the first side can be longer than the second side thereby forming a sharp pointed end via the first side at a distal-most portion. The exemplary configuration can be used for determination/detection of a tissue type, and/or determination of a location of insertion device/apparatus.
