Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If application softwares are used to query power consumption status, then power consumption data can be obtained, but additional burden is added to CPU and terminal power consumption increases
Solution Approach 1:
The patent introduces an electricity meter chip as an intermediary device between the battery and the terminal system. This chip directly measures power consumption parameters (voltage, current, power) at the electrical level, bypassing the need for software-based CPU calculations. The electricity meter chip communicates measurement data to the processor through standardized interfaces, thereby achieving accurate power consumption monitoring without burdening the CPU or increasing terminal power consumption.
2Loss of energy
If local adjustment on power consumption is performed on partial components, then power optimization is achieved for specific components, but power consumption optimization for the entire terminal is limited
Solution Approach 1:
The electricity meter chip serves multiple functions simultaneously: it measures voltage, current, and power consumption; provides real-time monitoring data; enables both local component optimization and overall terminal power management; and interfaces with the processor for system-wide coordination. This multi-functional design allows the system to achieve comprehensive power optimization across all components rather than being limited to isolated local adjustments.
3Ease of operation
If simple bar diagram is used to display battery power, then display is simple, but actual operation status of battery supply cannot be reflected
Solution Approach 1:
The patent segments the battery power information display into multiple dimensions: basic power level (bar diagram), real-time power consumption rate, remaining battery life estimation, and detailed component-wise power consumption breakdown. The electricity meter chip enables collection of granular data that is then presented through segmented information layers, allowing users to access both simple overview and detailed status information as needed.
4Loss of information
If application softwares are used to monitor power consumption, then power consumption data can be queried, but user interactivity is lacking and users cannot make corresponding responses
Solution Approach 1:
The system implements a closed-loop feedback mechanism where the electricity meter chip continuously monitors power consumption, the processor analyzes the data in real-time, and the system provides immediate feedback to users through the display interface. This feedback includes actionable information such as estimated battery life, current power consumption rate, and recommendations for power-saving actions, enabling users to make informed decisions and respond appropriately to power status changes.
