Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the foldable device provides only basic information through AOD in flex mode, then the device complexity is low and energy consumption is minimal, but the user experience and information quality are limited
Solution Approach 1:
The patent combines data from multiple sources including wearable devices, sensors within the foldable device, and activity recognition algorithms to provide comprehensive context information. This merging of multiple information sources resolves the contradiction by enriching information quality while managing system complexity through integrated processing.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives raw data from sensors and wearable devices, processes this information through activity recognition algorithms, and generates context information. This intermediary layer abstracts the complexity from the user interface while maintaining rich information delivery.
2Measurement precision
If the foldable device integrates multiple sensors and communication circuits to obtain user activity information, then the context information quality improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent makes existing components multi-functional by enabling them to serve both traditional purposes and new context detection functions. For example, the flexible display serves as both the user interface and a sensor for detecting folding states, while existing processors handle both standard operations and activity recognition algorithms, thereby improving measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The patent implements dynamic sensor activation and data collection strategies where sensors are activated only when needed based on device state and user context. This dynamic approach allows high measurement precision when context information is required while reducing overall system complexity and power consumption during normal operation.
3Adaptability or versatility
If the foldable device processes and analyzes user activity data in real-time, then the context information relevance improves, but the energy consumption increases
Solution Approach 1:
The patent implements periodic processing where user activity data is analyzed at specific intervals or triggers rather than continuously. Context information is updated periodically based on changes in device state, wearable device data, or user interactions, maintaining high adaptability and relevance while significantly reducing energy consumption compared to continuous real-time processing.
Solution Approach 2:
The patent performs preliminary processing and filtering of user activity data at the source (wearable devices and sensors) before transmitting to the foldable device. This preliminary action reduces the amount of data requiring intensive real-time processing, thereby maintaining context relevance while lowering overall energy consumption across the system.
