Solution Overview
Problem
Current methods for addressing traumatic nightmares, particularly in military veterans with PTSD, are costly, complex, and often ineffective in preventing nightmares from occurring, and may be hindered by self-esteem issues preventing treatment seeking.
Innovation Solution
A computer-implemented method using a watch connected via Bluetooth to a phone, employing accelerometers, gyroscopes, and heart rate monitors to detect and intervene in nightmares through haptic feedback, calculating stress magnitudes and determining appropriate intervention intensity based on collected data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clinical treatments such as prolonged exposure are used to address traumatic nightmares, then treatment effectiveness may be improved, but cost and complexity increase significantly
Solution Approach 1:
The patent replaces complex clinical treatment systems with a wearable technology system that uses accelerometers, gyroscopes, and heart rate monitors to detect nightmares and deliver haptic feedback interventions. This substitution of mechanical/clinical systems with electronic/wearable systems reduces complexity while maintaining treatment effectiveness.
Solution Approach 2:
The wearable system enables self-service treatment by automatically detecting nightmare episodes and delivering interventions without requiring clinical professionals. The system monitors physiological signals, identifies nightmare patterns, and provides haptic feedback responses autonomously, eliminating the need for complex clinical treatment protocols.
2Reliability
If clinical treatments are pursued, then nightmare reduction may be achieved, but cost increases significantly
Solution Approach 1:
The patent employs inexpensive wearable components such as accelerometers, gyroscopes, and heart rate monitors that can be mass-produced at low cost. These disposable or low-cost components replace expensive clinical treatment programs, making nightmare intervention accessible to military veterans and other populations without requiring significant financial investment.
Solution Approach 2:
The system creates a digital copy of physiological data from wearables and processes this information through algorithms to identify nightmare patterns. This copying and analysis of physiological signals allows for cost-effective nightmare detection and intervention without requiring expensive clinical assessments or prolonged treatment programs.
3Ease of manufacture
If readily available technology is used for monitoring, then cost decreases, but measurement precision may be compromised
Solution Approach 1:
The patent combines multiple sensor types (accelerometers, gyroscopes, and heart rate monitors) within a single wearable system to achieve precise sleep cycle detection. By merging the data from these multiple inexpensive sensors and processing them through integrated algorithms, the system achieves measurement precision comparable to expensive clinical monitoring equipment while maintaining low cost.
Solution Approach 2:
The system continuously monitors physiological signals and provides real-time feedback through haptic feedback responses. This feedback mechanism allows the system to adjust its detection algorithms based on observed patterns, improving measurement precision over time. The feedback loop enables the system to refine its nightmare detection accuracy while using inexpensive wearable technology.
4Reliability
If intervention intensity is increased, then nightmare interruption effectiveness improves, but user comfort and acceptance decrease
Solution Approach 1:
The patent implements dynamic intervention intensity adjustment based on detected nightmare severity and user response. The haptic feedback system can vary its intensity levels, transitioning from subtle vibrations to more pronounced responses depending on the situation. This dynamic adaptation ensures effective nightmare interruption while maintaining user comfort and acceptance, avoiding the need for consistently high-intensity interventions that would compromise ease of operation.
