Solution Overview
Problem
The increasing complexity of content-processing components in devices leads to higher power consumption, which can be inefficient and reduce battery life in battery-powered devices, despite enhancing user experience.
Innovation Solution
A device comprising a content-processing component, a sensor to detect eyelid activity, and a processor that enables or disables the content-processing operation based on eyelid state, such as being open or closed, to conserve power by intermittently disabling content processing during blinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content-processing components are made more complex to enhance user experience, then content-processing capabilities are improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the content-processing operation state changeable based on real-time eyelid state detection. The system transitions between enabled and disabled states dynamically, allowing the content-processing component to adapt its operation level according to user needs, thus resolving the contradiction between maintaining high processing capability and reducing power consumption.
Solution Approach 2:
The patent implements periodic action by intermittently enabling and disabling content-processing operations based on detected eyelid blinking patterns. Instead of continuous operation, the system uses periodic monitoring of eyelid state to determine when to activate or deactivate processing, reducing overall power consumption while maintaining user experience during actual viewing periods.
2Productivity
If content-processing operation is continuously enabled to maintain user experience, then content processing capability is preserved, but battery life is reduced
Solution Approach 1:
The patent uses feedback from the sensor detecting eyelid state to control the content-processing operation. The sensor continuously monitors whether the user's eyelid is open or closed and provides this information back to the control system, which then adjusts the processing operation accordingly. This feedback mechanism ensures content processing is available when needed (eyelid open) while conserving battery life during non-viewing periods (eyelid closed).
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces power consumption by disabling content processing during periods when the user is not viewing content, thereby extending battery life and improving energy efficiency without complex algorithms.

Data Source
AI summary
A device comprises a content-processing component operable to perform a content-processing operation. The device comprises a sensor operable to output data indicative of activity of an eyelid of a user of the device. The device comprises a processor configured to process the data output by the sensor, to cause the content-processing operation to be in an enabled state in response to the processing of the data output by the sensor indicating that the eyelid is open by more than an open-eyelid threshold, and to cause the content-processing operation to be in a disabled state in response to the processing of the data output by the sensor indicating that the eyelid is closed by more than a closed-eyelid threshold.
