Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pain treatment methods, such as analgesic drugs and transcutaneous electrical neurostimulation, suffer from side effects and practical limitations, while millimeter wave therapy devices are bulky and require high power flux density for effectiveness, making them inconvenient for continuous use.
Innovation Solution
A portable device that transmits electromagnetic waves with a power flux density of at least 0.5 milliwatts per square centimeter and frequencies between 3 and 120 gigahertz, allowing for continuous use on the body, particularly on innervated areas, with a miniaturized module design that can be integrated into wearable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If millimeter wave therapy devices use high power flux density to ensure effectiveness, then pain relief efficacy is improved, but device volume and weight increase making them bulky and inconvenient
Solution Approach 1:
The device divides the treatment area into multiple zones with different power flux density levels. High power density (0.5-2 W/cm²) is applied to specific target areas while lower power density is used in surrounding areas, allowing effective pain relief without requiring uniformly high power across the entire device surface, thus reducing overall device volume and power requirements.
Solution Approach 2:
The invention implements spatially varying power distribution where different regions of the electromagnetic wave source emit at different power levels. The high power flux density is concentrated precisely at the pain affected area while peripheral regions operate at lower power, optimizing therapeutic effect while minimizing device size and energy consumption.
2Reliability
If millimeter wave therapy devices transmit high frequency waves (30-300 GHz) with high power, then therapeutic effect is improved, but device complexity and power consumption increase
Solution Approach 1:
The device dynamically adjusts operating parameters including power flux density, frequency, and treatment duration based on the specific pain condition and patient response. This allows optimization of therapeutic effect while avoiding unnecessarily high power settings that would increase device complexity and power consumption.
Solution Approach 2:
The electromagnetic wave transmission is applied in periodic cycles with alternating high and low power phases. This periodic modulation achieves effective pain relief through cumulative therapeutic effect while reducing average power consumption and simplifying device design compared to continuous high power operation.
3Reliability
If traditional analgesic drugs are used to treat chronic pain, then pain relief is achieved, but side effects such as nausea, drowsiness, and heartburn occur
Solution Approach 1:
The invention replaces chemical pharmacological treatment with physical electromagnetic wave therapy. Millimeter waves in the 30-300 GHz range are transmitted through the skin to the pain affected area, producing therapeutic effects through non-thermal and thermal mechanisms without introducing chemical substances into the body, thereby eliminating drug-related side effects.
4Reliability
If transcutaneous electrical neurostimulation is used to treat pain, then pain relief is achieved, but the device becomes bulky requiring electrodes and electric generator
Solution Approach 1:
The invention replaces electrical neurostimulation with electromagnetic wave therapy. Instead of using electrical currents that require bulky generators and electrode systems, the device uses electromagnetic waves in the millimeter wave range that can be transmitted through simple antenna structures, significantly reducing device complexity while maintaining pain relief effectiveness.
