Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external medical devices for monitoring and treating cardiac conditions often require patients to have a certain level of technological comfort and understanding, which can vary significantly among individuals, leading to challenges in operation and effectiveness due to differences in physical and mental capabilities.
Innovation Solution
An external medical device equipped with monitoring circuitry and a controller that adapts its interaction mode based on patient input and user input, adjusting features such as textual, image, or video elements, audio, and tactile outputs to match the patient's comfort level and ability, thereby personalizing the user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the medical device uses a standardized user interface, then the device complexity is reduced, but the ease of operation deteriorates for patients with varying technological comfort levels
Solution Approach 1:
The user interface dynamically adapts its characteristics based on patient ability assessments. The system transitions from a static standardized interface to a dynamic one that adjusts complexity, terminology, and interaction modes according to real-time patient capability evaluations, resolving the contradiction between operational ease and device complexity
Solution Approach 2:
The system changes interface parameters such as terminology complexity, visual elements, and interaction requirements based on patient ability levels. By modifying these parameters dynamically, the system maintains ease of operation across different patient populations without requiring multiple specialized interfaces, thus managing device complexity
2Loss of information
If the device provides detailed technical information, then the information completeness is improved, but the ease of operation deteriorates for patients with limited technological understanding
Solution Approach 1:
The system applies local quality by tailoring the level of technical detail to specific patient needs. Different portions of the interface provide different levels of information density based on the patient's assessed ability, ensuring information completeness is delivered at an appropriate level without overwhelming the patient
Solution Approach 2:
The system uses feedback from patient interactions and ability assessments to adjust the level of technical information provided. This feedback loop ensures that information completeness is maintained while adapting to the patient's technological understanding level, preventing information overload
3Ease of operation
If the device uses simplified interface elements, then the ease of operation is improved, but the information completeness deteriorates for patients with higher technological comfort
Solution Approach 1:
The interface dynamically adjusts between simplified and detailed information based on patient ability assessments. For patients with higher technological comfort, the system provides more comprehensive information while maintaining ease of operation through intuitive design, avoiding the loss of information for any patient group
4Ease of operation
If the device adapts to individual patient abilities, then the ease of operation is improved, but the device complexity increases due to adaptive algorithms and multiple interaction modes
Solution Approach 1:
The system performs self-service by automatically assessing patient abilities and configuring the interface without requiring manual intervention. This automation reduces the operational burden on both patients and providers while managing device complexity through algorithmic decision-making rather than complex manual configuration systems
