Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional technologies focus on convenience and recovery of brain function in elderly individuals with existing brain dysfunction, then the degree of contribution to recovery of brain function is improved, but prevention of brain dysfunction before development is neglected
Solution Approach 1:
The system performs preliminary actions by accumulating episode data and constructing memory episodes before brain dysfunction develops. The information processing device continuously collects sensor data, generates keywords, and builds episode structures in advance, creating a reservoir of structured memories that can be recalled and utilized to prevent cognitive decline before it occurs.
Solution Approach 2:
The system segments brain function support into distinct phases: prevention phase (for individuals without brain dysfunction) and recovery phase (for individuals with existing dysfunction). By separating these functions and applying different technical approaches to each segment, the system achieves both preventive memory enhancement and therapeutic recovery support.
2Reliability
If the system accumulates and processes extensive episode data from daily interactions, then memory enhancement effectiveness is improved, but device complexity increases
Solution Approach 1:
The system extracts only essential elements from complex sensor data by generating keywords that capture the core meaning of interactions. Instead of processing entire audio, video, and sensor datasets, the system extracts salient keywords and phrases, storing them as condensed episode representations that maintain memory enhancement effectiveness while reducing processing complexity.
Solution Approach 2:
The system creates simplified copies of complex interactions by generating structured episode data from raw sensor inputs. Rather than storing and reprocessing original multi-modal sensor data, the system creates lightweight textual representations (keywords, episode summaries) that capture the essential memory-enhancing information in a more manageable format.
3Loss of information
If the system generates questions to draw out information concerning episode data, then episode data completeness is improved, but interaction time increases
Solution Approach 1:
The system applies partial action by generating questions selectively rather than continuously. It asks questions only when necessary to fill gaps in episode data or when sensor data indicates an opportunity for meaningful interaction. This selective questioning approach achieves sufficient episode completeness without excessive interaction time.
Solution Approach 2:
The system uses feedback from sensor data analysis to determine when questions should be generated. By monitoring interaction context, user engagement levels, and existing episode data completeness, the system dynamically adjusts question generation timing and frequency, asking questions only when they are most likely to be productive and well-received.
