Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electromagnetic radiation is delivered through the skin to a target location within the body, then the capability to perform internal medical procedures is improved, but the difficulty of delivering radiation precisely to the target location increases
Solution Approach 1:
The patent introduces an optical fiber as an intermediary medium to transmit electromagnetic radiation from an external source through the skin to the target location within the body. The optical fiber acts as a waveguide that carries the radiation precisely to the desired depth and location, solving the problem of difficult radiation delivery through tissue.
Solution Approach 2:
The patent replaces traditional mechanical radiation delivery methods with optical waveguide technology. Instead of using mechanical means to position radiation sources, the system uses optical fibers to guide electromagnetic radiation through the skin, enabling non-invasive or minimally invasive delivery to internal targets.
2Manufacturing precision
If a needle with wave guiding structure is used to deliver radiation, then the precision of radiation delivery is improved, but the device complexity increases
Solution Approach 1:
The patent combines the needle structure with the optical waveguide into a single integrated device. The optical fiber is inserted through the hollow needle, merging the mechanical delivery mechanism (needle) with the radiation delivery mechanism (waveguide) into one unified instrument that can be inserted through the skin and deliver radiation precisely.
Solution Approach 2:
The optical fiber is nested within the hollow needle structure. The waveguide is placed inside the needle lumen, creating a nested configuration where the radiation delivery component is housed within the mechanical delivery component, allowing both functions to be achieved through a single insertion.
3Reliability
If radiation sources are operated for medical procedures, then the effectiveness of treatments like disinfection is improved, but the risk of harmful effects from radiation increases
Solution Approach 1:
The patent incorporates feedback mechanisms to monitor and control the radiation delivery process. Sensors detect conditions at the target location (such as temperature, radiation dose, or treatment efficacy) and provide feedback to the control system, which adjusts radiation parameters in real-time to maximize therapeutic effect while minimizing harmful side effects.
Solution Approach 2:
The system dynamically changes radiation parameters (wavelength, intensity, duration, pulse frequency) based on the specific medical procedure and tissue characteristics. By adjusting these parameters, the treatment can be optimized for different applications (disinfection, ablation, stimulation) while staying within safe exposure limits for each tissue type.
