Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If power consumption is monitored under static ambient lighting conditions, then the monitoring process is simple, but the power consumption data does not accurately reflect actual usage patterns
Solution Approach 1:
The patent applies the Dynamics principle by transitioning from static ambient lighting conditions to dynamic lighting conditions that vary over time. The system controls lighting to simulate different usage scenarios (watching TV, browsing web, gaming) with varying intensities and durations, enabling the television to adapt its power consumption patterns accordingly. This dynamic approach ensures that power consumption measurements reflect actual usage patterns rather than static conditions.
Solution Approach 2:
The patent applies the Parameter changes principle by systematically varying lighting parameters (intensity, duration, timing) to create different usage scenarios. The system changes lighting conditions to match real-world situations such as daytime viewing versus nighttime viewing, and adjusts the television's power consumption settings in response to these parameter changes. This enables accurate measurement of power consumption across diverse operational conditions.
2Reliability
If ambient lighting is varied to reflect actual usage conditions, then power consumption profile accuracy improves, but the monitoring system complexity increases
Solution Approach 1:
The patent applies the Feedback principle by implementing a closed-loop system where the television's sensors detect ambient lighting conditions, and this information feeds back to the television's processor which adjusts power consumption settings accordingly. The system continuously monitors lighting levels and adapts operational parameters in real-time, ensuring that power consumption profiles reliably reflect actual usage conditions. This feedback mechanism automates the adaptation process without requiring complex manual intervention.
3Measurement precision
If multiple applications are opened and closed during monitoring, then the power consumption profile becomes more comprehensive, but the testing time increases
Solution Approach 1:
The patent applies the Periodic action principle by implementing cyclic sequences of opening and closing multiple applications during monitoring periods. The system systematically cycles through different applications (video player, web browser, games) in repeated sequences, allowing comprehensive power consumption profiling across all application types. This periodic testing approach ensures complete coverage of power consumption scenarios while maintaining efficient test execution through structured repetition.
Data Source
AI summary
A non-transitory computer-readable storage medium comprises instructions stored thereon. When executed by at least one processor, the instructions are configured to cause a computing system to vary at least one light source in a room, the room including the at least one light source and a television; monitor power consumption by the television while varying the at least one light source; and determine an average power consumption by the television during a time period when the power consumption was monitored.
