Garment Cuff Sensor Stiffener for Continuous Physiological Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for measuring physiological data, such as blood pressure, are not designed for continuous wear and can be invasive or uncomfortable, limiting their ability to provide multiple readings over time.
Innovation Solution
A garment cuff with a sensor panel and data acquisition module integrated into a wearable garment, using a stiffener member and adjustable fastener system to secure sensors against the user's limb with consistent pressure, allowing for prolonged data collection without discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specialized apparatus for measuring physiological data (e.g., sphygmomanometer with inflatable cuff) is used, then measurement precision is improved, but ease of operation deteriorates due to invasiveness and discomfort preventing continuous wear
Solution Approach 1:
The patent merges specialized physiological measurement sensors (ECG, PPG, BCG) with a常规 garment cuff structure, integrating the measurement function into everyday wearable clothing. This combination allows continuous monitoring without the discomfort of specialized medical devices, resolving the contradiction between measurement precision and ease of operation.
Solution Approach 2:
The patent changes the pressure parameter applied to the limb by using a fastener system that provides gentle, adjustable pressure rather than the high inflation pressure required by traditional sphygmomanometers. This parameter change enables continuous wear while maintaining measurement capability through sensors that function at lower pressure levels.
2Measurement precision
If specialized measurement devices are used, then measurement precision is improved, but duration of action deteriorates because they are not designed for continuous wear
Solution Approach 1:
By combining medical-grade sensors with a comfortable garment cuff, the device transitions from short-term medical use to long-term wearable monitoring. The integration allows the measurement system to function continuously as part of everyday clothing, extending duration of action while preserving measurement precision.
Solution Approach 2:
The garment cuff serves dual purposes: it provides the measurement function while also serving as comfortable everyday wearable clothing. This self-service approach eliminates the need for separate medical equipment, enabling continuous monitoring throughout daily activities without sacrificing measurement accuracy.
3Measurement precision
If sensors are secured tightly against the limb for accurate measurement, then measurement precision is improved, but object-affected harmful factors increase due to user discomfort and potential tissue damage
Solution Approach 1:
The patent changes the pressure parameter from high force required by traditional devices to gentle, adjustable pressure sufficient for sensor contact. The fastener system provides just enough pressure to maintain consistent sensor-limb contact for accurate measurement while remaining comfortable for continuous wear, thereby reducing harmful factors.
Solution Approach 2:
The sensor panel is localized to a specific region of the cuff where gentle pressure is applied only where needed for measurement, while the rest of the garment maintains comfort. This localized approach ensures measurement precision at the sensor site without subjecting the entire limb to harmful pressure.

AI summary
A garment cuff for detecting physiological data. The garment cuff includes: an elongate band having a first region and a second region and defining an adjustable loop for receiving a user limb based on the first region being positioned proximal the second region. The garment cuff includes a stiffener member coupled to the first region to define a substantially rigid base and a sensor panel affixed to the substantially rigid base on a user limb facing side of the first region. The garment cuff includes a fastener coupled to the elongate band and configured to position the sensor panel against the user limb with substantially consistent pressure.
