Standby Power Reduction via Sensing Unit Frame Image Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with camera lenses face challenges in power consumption during standby mode, as they continuously monitor the environment without detecting significant changes, leading to unnecessary power usage.
Innovation Solution
Incorporating a sensing unit that captures frame images and generates signals in standby mode, allowing the host processing unit to activate functions only when changes are detected, such as movement, thereby reducing power consumption and enhancing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera lens continuously monitors the environment in standby mode, then the device can detect changes and activate host functions when necessary, but the power consumption increases unnecessarily
Solution Approach 1:
The sensing unit performs preliminary monitoring of the environment in standby mode to detect changes before the host function is fully activated. This allows the system to prepare for potential host function activation while maintaining low power consumption by only activating the sensing unit, not the complete host system.
Solution Approach 2:
The sensing unit acts as an intermediary between the standby state and full host function activation. It monitors environmental changes and generates sensing signals that trigger host function activation only when necessary, preventing unnecessary power consumption while maintaining automatic activation capability.
2Loss of energy
If the host function is activated continuously to monitor environment changes, then no power is wasted, but the device cannot enter proper standby mode
Solution Approach 1:
The system segments the monitoring function into a separate sensing unit that can operate independently from the main host function. This allows the sensing unit to monitor environmental changes in standby mode while the host function remains inactive, preventing power waste while enabling proper standby mode operation.
Solution Approach 2:
The system dynamically adjusts its state based on sensing signals. When the sensing unit detects changes, it triggers host function activation. When no changes are detected, the host function remains in standby mode, optimizing power consumption based on actual environmental conditions rather than continuous operation.
3Use of energy by moving object
If the sensing unit operates in standby mode to detect frame image changes, then power is saved by activating host functions only when necessary, but the device complexity increases
Solution Approach 1:
The sensing unit is designed with multi-functionality, serving both as a standalone monitoring device in standby mode and as a trigger for host function activation. This universal design allows a single component to perform multiple functions, reducing the need for separate dedicated components and thereby limiting the increase in device complexity.
