Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wired connections and electrocardiogram synchronization are used in Vagus nerve electrostimulation devices, then synchronization accuracy is improved, but portability and user mobility deteriorate
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless system. The wearable device uses wireless communication to transmit electrostimulation signals and respiratory cycle data between the earpiece, chest band, and smartphone, eliminating physical cables and enabling user mobility while maintaining synchronization functionality through wireless data transmission and processing algorithms.
2Reliability
If wired connections are used for Vagus nerve electrostimulation, then signal transmission reliability is improved, but device portability and comfort deteriorate
Solution Approach 1:
The patent substitutes mechanical wired connections with wireless transmission systems. The earpiece and chest band communicate wirelessly with the smartphone, providing portability and comfort while maintaining signal transmission reliability through wireless communication protocols and data processing algorithms that ensure accurate synchronization of electrostimulation with the respiratory cycle.
3Manufacturing precision
If electrocardiogram synchronization is used, then therapeutic precision is improved, but device complexity and cost deteriorate
Solution Approach 1:
The patent employs a multi-functional wearable system where a single integrated device performs multiple functions: the earpiece delivers electrostimulation signals, the chest band monitors respiratory cycle, and the smartphone application manages therapy configuration and synchronization. This universal approach replaces specialized equipment like electrocardiogram machines with a consolidated wearable system that achieves therapeutic precision through respiratory-gated synchronization.

AI summary
The invention is a non-implantable device electro stimulator Vagus nerve synchronized by thoracic movements in humans to improve the body motor function of patients after suffering an ischemic stroke, consisting of an atrial mechanism with four Electrodes that stimulate the nerve branches located in an earpiece that electrically stimulate the endings of the Vagus nerve that are located in the area of the Cavum Conchae and the Cymba Conchae of the left ear and the right ear and which in turn connects wirelessly to a mobile application that configures the stimulation parameters, also has a breathing cycle sensing band to sense the breathing placed around the user's chest that measures the expansion and recoil of the chest during breathing.
