Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external measuring devices are used to measure power consumption, then power consumption measurements can be obtained, but the measurement setup becomes complicated and measurement errors are easily introduced
Solution Approach 1:
The patent combines the power measurement functionality directly into the mobile terminal by integrating a fuel gauge block and power management ASIC within the terminal itself. This merging eliminates the need for separate external measuring devices and complex external measurement setups, while maintaining measurement accuracy through the integrated architecture that directly monitors power consumption at the battery connection point.
Solution Approach 2:
The mobile terminal performs self-measurement of its own power consumption through integrated circuitry. The fuel gauge block and power management ASIC enable the terminal to autonomously monitor and report power consumption data without requiring external measurement equipment, thereby simplifying the measurement setup while maintaining measurement capability.
2Loss of information
If separate external measuring devices are used, then power consumption data can be collected, but correlating measurements with debug printouts becomes difficult and time-consuming
Solution Approach 1:
The patent merges power consumption measurement data with debug printout information into a unified output format. The integrated power management ASIC generates measurements that are automatically correlated with software debug information, eliminating the need for separate external measurement devices and manual correlation processes. This integration ensures that power data and software operation data are inherently synchronized.
Solution Approach 2:
The system provides automatic feedback by integrating power measurement data directly into the debug printout stream. This feedback mechanism ensures that power consumption information is immediately available alongside software operation information, enabling real-time correlation without manual intervention and reducing information loss.
3Ease of operation
If measurement equipment is made available for individual developers, then power consumption debugging can be performed, but the cost of specialized equipment increases
Solution Approach 1:
The mobile terminal provides self-service power measurement capability through integrated circuitry. Each terminal includes fuel gauge block and power management ASIC that enable any developer to perform power consumption debugging without requiring access to expensive specialized external equipment. This self-service approach democratizes access to power measurement functionality.
Solution Approach 2:
The integrated power management ASIC serves multiple functions including battery charging control, power consumption measurement, and debug information generation. This multi-functionality eliminates the need for separate specialized measurement equipment, making power measurement capability universally available across all terminals without increasing device complexity.
4Adaptability or versatility
If stationary lab measurement setups are used, then controlled measurement conditions can be maintained, but measurements cannot be performed on mobile terminals in dynamic network environments
Solution Approach 1:
The patent implements dynamic power measurement capability that adapts to mobile terminal operation in varying network conditions. The integrated power management ASIC continuously monitors power consumption while the terminal moves through different network environments, maintaining measurement precision by adapting to changing conditions rather than requiring controlled stationary lab setups.
Solution Approach 2:
The mobile terminal performs autonomous power measurement in its own dynamic operating environment. The integrated circuitry measures power consumption regardless of whether the terminal is stationary or moving, in controlled lab conditions or dynamic network environments, eliminating the need for external measurement equipment that would be required to maintain controlled conditions.

Data Source
AI summary
Power consumption of an electronic device is measured by using circuitry within the electronic device to make power consumption measurements of the electronic device at predetermined time intervals. Each of the power consumption measurements is provided to a user of the device. This may involve incorporating each of the power consumption measurements in a debug printout generated by the electronic device. The measurements may be initiated by retrieving a parameter from a storage area within the electronic device, and initiating the power consumption measuring techniques in response to detecting that the retrieved parameter is in a predetermined state.
