Solution Overview
Problem
Current physiological function detection systems are inconvenient and inefficient due to discomfort caused by patch electrodes and the need for numerous wires, which restrict user movement and fail to accurately detect body position changes, impacting health monitoring and safety.
Innovation Solution
A system comprising non-posture physiological sensors configured on objects that touch the body, such as clothing, coupled with switches, tension sensors, or pressure sensors, which share signal wires and use signal processing to accurately detect body position changes without disrupting user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If patch electrodes are used to obtain ECG signal, then ECG signal can be obtained continuously, but user comfort deteriorates due to skin discomfort
Solution Approach 1:
The patent extracts the electrode from the traditional patch form and integrates it into clothing fabric. The electrode is embedded in the textile material, allowing continuous ECG monitoring without skin discomfort caused by adhesive patches. This extraction of the electrode from its conventional form and integration into clothing resolves the contradiction between continuous monitoring and user comfort.
Solution Approach 2:
The clothing serves multiple functions: it acts as both wearable fabric and as an ECG monitoring device. The electrode-integrated clothing combines the functions of clothing protection with physiological signal acquisition, eliminating the need for separate patch electrodes and enabling continuous comfortable monitoring.
2Measurement precision
If numerous electrodes and signal wires are used to obtain ECG, then ECG signal quality improves, but device complexity increases and user mobility is restricted
Solution Approach 1:
The patent merges multiple electrodes and signal wires into a single integrated clothing structure. The electrodes are embedded in the fabric with integrated wiring, combining what would traditionally be separate components into a unified wearable system. This reduces the number of external wires and components while maintaining ECG signal quality.
Solution Approach 2:
The patent uses flexible textile material as the substrate for electrodes and wiring. The clothing fabric serves as a flexible carrier that accommodates multiple electrodes and signal pathways without creating rigid structures or excessive external wiring, thus maintaining signal quality while reducing device complexity and improving mobility.
3Ease of operation
If signal wires are made short and few for user comfort, then user comfort improves, but ECG signal acquisition capability deteriorates
Solution Approach 1:
The patent transitions from external wire-based signal transmission to integrated fabric-based signal pathways. By embedding electrodes and wiring within the clothing structure, the system eliminates the need for long external wires while maintaining signal acquisition capability through the fabric's conductive pathways and integrated electrode positions.
4Adaptability or versatility
If traditional ECG system with many wires is used, then ECG signal can be obtained from various postures, but user mobility is restricted
Solution Approach 1:
The patent creates a dynamic wearable system where electrodes are distributed throughout the clothing fabric, allowing the system to adapt to various body postures and movements. The flexible integrated wiring and strategically placed electrodes maintain signal quality across different positions and activities, enabling posture detection while preserving user mobility.
