Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional diagnosis techniques (MRI, X-ray, blood tests) are used, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex mechanical and chemical diagnostic systems (MRI machines, X-ray equipment, blood test procedures) with an electromagnetic sensing system that uses a coil to detect conductivity changes in tissues. This substitution maintains diagnostic capability while dramatically reducing system complexity and making the device portable and easy to operate.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the diagnostic device and the human body. The coil generates an electromagnetic field that interacts with conductive fluids in the body, and changes in the field's electrical characteristics indicate health conditions. This intermediary approach enables non-invasive, simple diagnostics while maintaining measurement precision.
2Measurement precision
If traditional diagnosis techniques are used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex mechanical diagnostic procedures requiring trained professionals with a simple electromagnetic sensing device that can be easily operated. The coil-based sensor automatically detects conductivity changes without requiring physical examination skills, making the device easy to operate while maintaining diagnostic accuracy.
Solution Approach 2:
The diagnostic system performs self-measurement by automatically detecting conductivity changes in the body through the coil. The device does not require manual manipulation or interpretation by operators - it autonomously senses health conditions and provides results, enabling anyone to perform accurate diagnostics without training.
3Measurement precision
If invasive procedures are used, then measurement precision is improved, but object-affected harmful factors increase
Solution Approach 1:
The patent replaces invasive mechanical procedures (needles, surgical tools) and radiation-based imaging (X-ray, CT) with a non-invasive electromagnetic sensing approach. The coil detects conductivity changes through the skin without breaking the skin barrier or exposing the patient to harmful radiation, eliminating invasiveness while maintaining detection accuracy.
Solution Approach 2:
The patent converts the naturally conductive properties of body fluids (which could be considered a 'harmful' factor due to potential for interference) into a beneficial diagnostic signal. By detecting changes in conductivity caused by fluid accumulation or blood flow variations, the system transforms what could be noise into useful health information without any invasive intervention.
4Productivity
If continuous monitoring is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent enables continuous monitoring by maintaining a constant electromagnetic field through the coil that continuously interacts with body tissues. The system can track conductivity changes over time without interruption, providing ongoing health monitoring. This continuous action is achieved through a simple, low-power electromagnetic field rather than complex mechanical or computational systems.

AI summary
Techniques are described for a non-invasive detection of a health condition of an organ. In an example, the electrical conductivity of the organ reflects the organ's health of. An inductive damping sensor can be used to detect the organ's electrical conductivity and, thus, its health. The inductive damping sensor can be placed in proximity of the organ such as the organ is within the magnetic field generated based on a coil of the inductive damping sensor. The conductivity of the organ impacts the inductance and the resistance of the coil. Hence, the inductance and/or resistance of the coil can be measured, where the measurements can be associated with the health of the organ.
