Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If ML models are pre-loaded into memory for quick access, then model availability and response time are improved, but device memory consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-loading ML models into memory based on predicted future usage scenarios. The device analyzes current context (location, activity, time) and proactively loads models that are likely to be needed soon, reducing future loading delays without requiring all models to be permanently resident in memory
Solution Approach 2:
The system dynamically adjusts the ML model loading strategy based on real-time device state. Memory allocation for ML models is flexible and adapts to available resources, user behavior patterns, and environmental context. The device continuously monitors memory usage and adjusts which models remain in memory versus being stored on external storage, optimizing the balance between quick access and memory conservation
2Adaptability or versatility
If multiple ML models are kept in memory for different applications, then model versatility is improved, but device resource constraints are worsened
Solution Approach 1:
The system implements a universal memory management framework that handles multiple ML models with different requirements. A single memory management module serves multiple functions: tracking model usage patterns, predicting future needs, managing memory allocation, and coordinating with external storage. This multi-functional approach enables versatile model support without requiring separate management systems for each model
Solution Approach 2:
The system changes key parameters including memory allocation sizes, model priority levels, and loading thresholds based on device state and usage patterns. By dynamically adjusting these parameters, the device can accommodate varying numbers and types of ML models in memory while adapting to resource constraints. The memory allocation for each model is not fixed but can be modified based on current needs and available resources
3Productivity
If ML models are loaded based on predicted usage, then model loading efficiency is improved, but system complexity increases
Solution Approach 1:
The system incorporates feedback loops where actual model usage is monitored and compared against predictions. This feedback informs and refines future predictions, allowing the system to learn from past behavior patterns. The feedback mechanism includes tracking which models are actually used versus which were predicted to be used, adjusting prediction algorithms accordingly, and continuously improving loading efficiency over time
Solution Approach 2:
The memory management system performs self-service by automatically making decisions about which models to load without requiring manual intervention. The system autonomously analyzes usage patterns, predicts future needs, and executes loading decisions based on available resources. This self-service capability reduces the operational complexity burden on users while maintaining sophisticated model management

AI summary
Loading and unloading of ML models into an ML model cache or system memory of an electronic eyewear device is managed based on which applications are active or available and predicted activities. Sensor inputs are processed to detect whether the electronic eyewear device has moved or is predicted to move and new ML models are downloaded based on updated location information or observable visual information. Sensor inputs are also processed to determine whether the electronic eyewear device has changed state or resource availability and whether the ML model cache or system memory needs to be resized to accommodate new ML models for the changed conditions. If so, stored ML models are updated to reflect the new device state by unloading an ML model, receiving a new ML model based on the changed state or resource availability and a processing priority of the new ML model, or both.
