Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MRI or other imaging instruments are used to detect soft tissue injury, then detection capability is improved, but cost and time consumption increase significantly
Solution Approach 1:
The patent replaces complex mechanical imaging systems (MRI, ultrasound) with a simple electrical measurement system. Instead of using heavy imaging equipment to detect tissue injury indirectly through edema, the invention applies microcurrent through skin probes and measures electrical properties directly at the injury site, achieving rapid detection without expensive imaging equipment.
Solution Approach 2:
The invention extracts the essential detection function from complex imaging systems. Rather than using entire MRI or ultrasound machines, it isolates the core need (detecting tissue injury) and implements it through a simplified microcurrent measurement approach that only requires probes and a measurement device.
2Measurement precision
If MRI or other imaging instruments are used to detect soft tissue injury, then detection capability is improved, but device cost increases significantly
Solution Approach 1:
The patent uses inexpensive, simple probes that can be disposable or easily replaced, replacing the need for expensive imaging equipment. The measurement device itself is relatively simple and low-cost compared to MRI machines, making the overall system much more affordable while maintaining detection capability.
Solution Approach 2:
The invention substitutes expensive mechanical imaging systems with a simple electrical measurement system using basic probes and a measurement device, dramatically reducing equipment cost while maintaining the ability to detect soft tissue injury.
3Measurement precision
If MRI or other imaging instruments are used to detect soft tissue injury, then detection capability is improved, but operational complexity increases
Solution Approach 1:
The invention extracts only the essential detection function from complex imaging systems, removing the need for sophisticated equipment operation. The simplified probe-based microcurrent measurement requires minimal training compared to operating MRI or ultrasound machines.
Solution Approach 2:
The device is designed to be easily operable with minimal training, allowing users to perform measurements themselves without requiring specialized medical imaging expertise. The automatic measurement and clear indicators make it self-explanatory and easy to use.
4Measurement precision
If indirect detection methods like edema detection are used, then soft tissue injury can be detected, but detection directness and speed are reduced
Solution Approach 1:
The patent replaces indirect detection methods (detecting edema as a secondary effect) with direct detection by measuring electrical properties of the injured tissue itself. This substitution enables immediate detection at the injury site without waiting for secondary effects to manifest.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides a direct, objective, and cost-efficient means to detect soft tissue injuries, offering a significant reduction in time and cost compared to existing imaging techniques, with a 70% drop in microcurrent measured over injured tissue, facilitating accurate injury detection and monitoring of healing.
Implementation Method 1
The apparatus works by pairing electronic and mechanical components to detect and measure the severity of soft tissue injury. The apparatuses and methods of the invention measure microcurrent applied through the skin between two probes.
Data Source
AI summary
This invention detects tissue injury by measuring decreased skin conductance as shown by research. Two electrical probes on the device are placed onto a subject's skin. The device sends an electrical microcurrent from one probe, through the subject's skin, to the other probe. A gauge measures the microcurrent in microamps, and a speaker emits a tone with pitch and volume proportional to the percentage of maximum conductance. Per research, the skin conductance will decrease significantly over a site of tissue injury, such as an average of around 70% over a sprained ankle. Also, force gauges measure the force applied to the electrical probes for consistency of measurement. Cotton pads are placed at the tips of the electrical probes for hygiene.
