Solution Overview
Problem
There is currently no electrical stimulation therapy that effectively inhibits cyclooxygenase-2 (COX-2) without causing nerve injury or side effects associated with drug accumulation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If NSAIDs are used to inhibit COX and relieve pain, then inflammation and pain are reduced, but drug accumulation causes side effects and gastrointestinal mucosa injury
Solution Approach 1:
The patent replaces chemical pharmacological action with physical electrical stimulation. The electrical stimulation device uses controlled electrical signals (specific frequency and intensity parameters) to inhibit COX-2 expression and reduce pain, substituting the chemical drug mechanism with a physical field-based mechanism that avoids drug accumulation and metabolic side effects
Solution Approach 2:
The patent employs specific electrical stimulation parameters (frequency, intensity, pulse duration) to achieve selective inhibition of COX-2. By optimizing these physical parameters, the treatment achieves therapeutic effect while avoiding the side effects associated with chemical drugs, demonstrating parameter-based precision control
2Object-affected harmful factors
If COX-2 is inhibited to reduce inflammation, then pain relief is achieved, but existing methods cause nerve injury or require drug accumulation
Solution Approach 1:
The patent uses precisely controlled electrical stimulation parameters (frequency, intensity, pulse width) to selectively inhibit COX-2 expression in inflammatory cells without affecting nerve function. The specific parameter ranges are optimized to achieve therapeutic inhibition of neuroinflammation while maintaining nerve safety, avoiding both drug toxicity and physical injury
Solution Approach 2:
The electrical stimulation acts as an intermediary physical modality that indirectly inhibits COX-2 expression through cellular signaling pathways. Rather than directly damaging nerves or using toxic chemicals, the electrical fields modulate cellular activity to reduce inflammatory mediator production, providing a safe intermediate mechanism
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 electrical stimulation device effectively reduces COX-2 levels in the organism within 24 hours, relieves pain, reduces neural sensitivity, and inhibits neuroinflammatory responses without causing nerve injury, maintaining effects for at least 1 hour after treatment.
Implementation Method 1
The electrical stimulator is coupled to the electrode assembly and generates an electrical stimulation signal. The electrical stimulation signal is transmitted to a target region of an organism through the electrode assembly.

AI summary
An electrical stimulation device includes an electrode assembly and an electrical stimulator. The electrical stimulator generates an electrical stimulation signal and is coupled to the electrode assembly. The electrical stimulation signal is transmitted to a target region of an organism through the electrode assembly. The electrical stimulation signal contains a plurality of burst signals, and the burst signals have the burst frequency between 0.1 Hz and 1,000 Hz. Each burst signal contains a plurality of pulses, and the pulses have the pulse frequency between 1 kHz (kilohertz) and 1,000 kHz. The electrical stimulation signal reduces the level of cyclooxygenase-2 (COX-2) of the organism.
