Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current health monitoring devices are used for ambulatory patients, then data collection capability is provided, but the devices are bulky and require separate batteries which disrupt continuous data collection
Solution Approach 1:
The patent combines the battery, electronic components, and sensor elements into a single integrated patch device. The rechargeable battery is embedded within the patch housing, eliminating the need for separate battery packs and reducing the number of discrete components the patient must carry and manage.
Solution Approach 2:
The patch is designed as a multi-functional integrated system that simultaneously performs sensing, data processing, wireless communication, and power management functions. The single device serves multiple purposes: collecting physiological data via electrodes, processing signals through integrated circuits, storing data in memory, transmitting data via wireless radio, and managing power through an embedded rechargeable battery.
2Use of energy by moving object
If separate batteries are used in health monitoring devices, then power supply is provided, but battery replacement needs disrupt continuous data collection
Solution Approach 1:
The patch incorporates a rechargeable battery that can be recharged while the device is being worn or during brief removal periods. The power management circuit monitors battery charge levels and manages power distribution in advance, ensuring continuous operation without interruption to data collection.
Solution Approach 2:
The integrated rechargeable battery system enables continuous power supply to the patch electronics and sensors. The power management circuit ensures uninterrupted operation by managing power distribution from the battery to various components, eliminating gaps in data collection that would occur with battery replacement.
3Volume of moving object
If compact patch design is implemented, then wearability is improved, but integration of battery and electronics becomes more challenging
Solution Approach 1:
The patch employs a nested arrangement where the battery is positioned within the housing structure, electronic components are mounted on circuit boards that are integrated into the same housing, and sensing elements are positioned on the skin-contact surface. This nested configuration maximizes component density while maintaining a compact external form factor suitable for comfortable wear.

AI summary
An electrical patch and associated system for acquisition of physiological data is described. The patch has a design that enables a variety of configurations depending upon the requirements physiological measurements to be made. Patches with single input channels to patches with multiple input channels, processing capabilities and radio communication can all use the same physical configuration. The design includes a battery management system to enable long term data acquisition and an optimization process that includes mirroring of algorithms on the patch and devices local to the user with algorithms running on a centrally located server. The server can then optimize data acquisition and analysis algorithms. The components of the system and methods of use are included.
