Solution Overview
Problem
Traditional biofeedback methods are often obtrusive and limited to controlled environments, failing to provide effective communication of physiological data to users in real-time, especially for heart rate variability, which is linked to stress levels.
Innovation Solution
A wearable device system that includes biosensors and a haptic feedback system, which monitors real-time physiological data and provides unobtrusive feedback through patterns of stimulation, allowing users to become aware of and potentially control their internal states, using a combination of biosensors, computing systems, and haptic feedback nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional biofeedback techniques are used to train higher heart rate variability, then stress levels can be reduced, but the techniques become obtrusive and limited to controlled environments
Solution Approach 1:
The patent replaces traditional mechanical/audiovisual feedback systems with a haptic feedback system that uses tactile sensations delivered through the wearable device. This substitution enables biofeedback to be delivered unobtrusively through skin contact, allowing users to receive feedback during daily activities without being confined to controlled environments.
Solution Approach 2:
The patent changes the parameter of feedback delivery from external sensory modalities (visual/audio) to tactile haptic feedback. This parameter change allows the feedback to be integrated into the user's body perception, making it less obtrusive and suitable for use in natural, uncontrolled environments while maintaining effectiveness.
2Loss of information
If real-time physiological monitoring is implemented, then users can build awareness of internal states, but the device complexity increases
Solution Approach 1:
The wearable device integrates multiple functions including physiological sensing, real-time data processing, and haptic feedback delivery within a single unified system. This multi-functionality reduces the need for separate devices and simplifies the overall system architecture while enabling comprehensive real-time monitoring and feedback.
Solution Approach 2:
The patent implements a nested system architecture where the haptic feedback mechanism is integrated within the wearable device housing, which itself contains the sensing and processing components. This nesting approach consolidates multiple functional elements into a compact form factor, reducing device complexity while maintaining real-time monitoring capabilities.
