Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports apparel lacks effective integration of bioelectric signal detection technology, such as ECG and EMG, for real-time monitoring during exercise, due to inadequate skin contact and conductivity.
Innovation Solution
The apparel incorporates a base layer with conductive electrodes and a flocked fibre layer made of conductive fibre particles, which improves skin contact and conductivity through a flocking process, allowing for wireless transmission of physiological signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional skin electrodes are placed on the skin, then bioelectric signals can be detected, but skin contact and conductivity are inadequate
Solution Approach 1:
The patent applies composite materials by combining conductive fibers with flocking technology to create an electrode layer that integrates multiple functional properties. The conductive fiber particles are embedded in a flexible matrix material, creating a composite structure that simultaneously provides electrical conductivity, mechanical flexibility, and enhanced skin contact capability, thereby resolving the contradiction between signal detection reliability and skin contact quality
Solution Approach 2:
The patent employs parameter changes by modifying the physical and electrical parameters of the electrode material through flocking process. The conductive fiber particles are deposited with specific density, orientation, and conductivity parameters to optimize both skin contact area and electrical signal transmission, addressing the contradiction between adequate skin contact and reliable signal detection
2Reliability
If conductive materials are used for electrodes, then conductivity is improved, but comfort and skin contact are reduced
Solution Approach 1:
The patent applies local quality by creating regions with different properties within the electrode layer. The conductive fiber particles are distributed non-uniformly, with higher concentration at contact points for optimal conductivity, while other regions maintain softer, more flexible characteristics for comfort. This localized differentiation resolves the contradiction between electrode conductivity and user comfort
Solution Approach 2:
The patent uses the flocking layer as an intermediary between the conductive materials and the skin. This intermediate layer consists of fine fiber particles that provide a soft, comfortable interface while maintaining electrical conductivity through the conductive fiber network, thereby mediating between the conflicting requirements of conductivity and comfort
