Solution Overview
Problem
Conventional systems for assessing a person's functional ability to perform tasks in familiar surroundings are inadequate, leading to the need for costly face-to-face consultations with medical professionals, which negates the benefits of increased independence and empowerment.
Innovation Solution
A system comprising a task identification unit, task complexity unit, functional ability unit, and assessment unit that generates an assessment signal based on task-specific complexity and personal functional ability, reducing the burden on caregivers and improving self-empowerment while maintaining care and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional monitoring systems are used to detect ADLs, then independence and empowerment of the person are increased, but adequate assessment and monitoring of functional ability is not provided
Solution Approach 1:
The patent introduces an intelligence system as an intermediary between the sensor system and the user interface system. This intelligence system uses artificial intelligence techniques to interpret sensor signals and assess functional ability, bridging the gap between simple activity detection and comprehensive functional assessment, thereby maintaining both independence and assessment accuracy.
Solution Approach 2:
The system enables self-monitoring of functional ability through automated analysis of daily living activities. The intelligence system automatically processes sensor data to generate functional ability assessments without requiring external medical professionals, allowing the person to maintain independence while receiving accurate assessment.
2Reliability
If face-to-face consultations with medical professionals are conducted, then adequate assessment of functional ability is provided, but time and resource requirements increase
Solution Approach 1:
The patent replaces the mechanical system of face-to-face medical consultations with an automated electronic system. The intelligence system uses artificial intelligence to perform functional ability assessment that previously required medical professionals, thereby maintaining assessment accuracy while eliminating time loss associated with scheduling and traveling for consultations.
Solution Approach 2:
The system creates a virtual copy of the medical assessment process through automated analysis of daily living activities. By using sensor data and AI algorithms to replicate the assessment function, the system provides medical-grade evaluation without requiring the physical presence of medical professionals, saving significant time and resources.
3Device complexity
If one-time assessment of functional ability is performed, then simplicity is maintained, but variability of functional performance over time cannot be assessed
Solution Approach 1:
The patent implements continuous monitoring of functional ability through ongoing analysis of daily living activities. The sensor system and intelligence system work continuously to track changes in functional performance over time, ensuring that variability is captured while the automated nature of the system prevents excessive complexity.
Solution Approach 2:
The system performs periodic reassessment of functional ability by continuously analyzing ADL patterns. Through regular, automated evaluation of daily activities, the system captures temporal variability in functional performance without requiring complex intervention, as the assessment is integrated into the routine monitoring of daily life.
