Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operating system is turned on to display battery capacity, then the user can know the battery capacity, but the power consumption increases and the system cannot remain in a low-power state
Solution Approach 1:
The patent extracts the battery capacity display function from the operating system and implements it independently through the embedded controller and LED module. This allows the battery status to be displayed without requiring the main operating system to be running, thus resolving the contradiction between information availability and power consumption.
Solution Approach 2:
The embedded controller autonomously monitors battery capacity and controls the LED module to display status information without requiring intervention from the operating system. This self-service mechanism enables continuous battery information display while keeping the main system in low-power state.
2Ease of operation
If the SAR sensor continuously monitors external environment, then the triggering condition can be detected, but the power consumption increases
Solution Approach 1:
The SAR sensor performs external environment sensing periodically or on-demand rather than continuously, triggered by specific conditions such as user interaction. This periodic action reduces power consumption while maintaining ease of operation when needed.
Solution Approach 2:
The system performs external environment sensing in advance to detect triggering conditions before initiating battery capacity display. This preliminary action allows the system to prepare for display operations only when necessary, avoiding unnecessary power consumption.
3Loss of time
If the LED module displays battery capacity, then the user can rapidly view battery status, but additional components are required
Solution Approach 1:
The LED module, which may already exist in the device for other status indications, is repurposed to display battery capacity information. This multi-functional use of existing components enables rapid battery status display without significantly increasing device complexity.
Solution Approach 2:
The embedded controller acts as an intermediary between the battery module and the display system, managing the complexity of battery capacity calculation and LED control. This intermediary approach simplifies the overall system architecture by centralizing the control logic in a dedicated component.
