Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data collection frequency and quantity are increased, then data quality and trial success likelihood improve, but participant burden increases adversely affecting recruitment and retention
Solution Approach 1:
The system changes the parameters of data collection by using machine learning models to determine optimal visit schedules and data collection frequencies. Instead of fixed frequent visits, the system dynamically adjusts collection parameters based on trial phase, participant characteristics, and data priorities, reducing overall burden while maintaining data quality through targeted collection at optimized intervals
Solution Approach 2:
The system implements feedback mechanisms where machine learning models continuously evaluate participant responses, data quality metrics, and trial progress to adjust future data collection schedules. This feedback loop allows the system to maintain high data quality by intensifying collection when needed while reducing burden during stable phases, creating an adaptive balance between data needs and participant burden
2Ease of operation
If data collection frequency is reduced, then participant burden decreases improving recruitment and retention, but data quality and trial success may be adversely affected
Solution Approach 1:
The system transforms fixed data collection parameters into dynamic, optimized parameters using machine learning. It identifies critical time points and phases where data collection must be intensive versus periods where reduced collection is acceptable, changing the temporal parameters of data collection to match actual trial needs and participant capacity
Solution Approach 2:
The system applies partial action by collecting comprehensive data only when critical thresholds are reached or during high-priority trial phases, rather than continuous intensive collection. Machine learning models identify when full data collection is necessary versus when reduced collection suffices, applying excessive action (intensive collection) selectively rather than uniformly
3Measurement precision
If comprehensive data collection protocols are implemented, then data quality improves, but trial complexity and design difficulty increase
Solution Approach 1:
The system introduces machine learning models as intermediary components between trial designers and data collection protocols. These models automatically process complex design considerations, evaluate multiple parameter combinations, and generate optimized schedules, acting as a mediator that handles the computational complexity while presenting simplified recommendations to human designers
Solution Approach 2:
The system replaces manual trial design processes with automated machine learning-based optimization. Instead of clinicians manually balancing numerous conflicting requirements, the system uses computational algorithms to automatically evaluate design parameters, simulate outcomes, and generate optimized protocols, substituting mechanical human analysis with automated intelligent systems
4Adaptability or versatility
If manual trial design processes are used, then flexibility in adapting to various trial conditions is maintained, but time and resources required for optimization increase
Solution Approach 1:
The system performs preliminary actions by pre-training machine learning models on extensive trial data and pre-evaluating multiple design scenarios before actual trial implementation. This allows the system to have optimization recommendations ready in advance, reducing the time needed during actual trial setup while maintaining adaptability through pre-computed parameter evaluations
Solution Approach 2:
The system implements rapid feedback loops where machine learning models instantly evaluate design parameter changes and provide optimization recommendations. This real-time feedback capability allows trial designers to explore multiple scenarios quickly and adapt designs iteratively without the time-consuming manual analysis that would otherwise be required for each design modification
