Solution Overview
Problem
The challenge is to extend the operating time of a monitoring system powered by a battery, which faces power fluctuations due to varying energy generation from natural sources, leading to potential interruptions in data recording and service quality.
Innovation Solution
A data processing apparatus that adjusts its data conversion settings based on the remaining battery capacity, transmitting data with a high image quality setting when power is abundant and reducing data amount with a low image quality setting when power is scarce, thereby optimizing power consumption and extending operational time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the monitoring system transmits data with high image quality setting, then the data quality is improved, but the power consumption increases and operating time decreases
Solution Approach 1:
The patent applies dynamics by making the data transmission quality adjustable rather than fixed. The data processing apparatus dynamically changes the image quality setting based on the remaining battery capacity, transitioning between high quality (when power is abundant) and low quality (when power is scarce), thereby resolving the contradiction between maintaining quality and extending operating time
Solution Approach 2:
The patent changes the parameter of image quality (data compression ratio) based on power availability. When battery capacity is sufficient, the system uses high quality settings; when capacity drops below a threshold, it switches to low quality settings with higher compression, thus adapting the quality parameter to power conditions to extend operating time
2Duration of action of moving object
If the monitoring system reduces data transmission quality, then the power consumption decreases and operating time extends, but the data quality deteriorates
Solution Approach 1:
The system dynamically adjusts data quality based on real-time power status. Rather than permanently reducing quality, it adaptively changes the quality level according to battery capacity, maintaining high quality when possible and accepting lower quality only when necessary to extend operation
Solution Approach 2:
The patent changes the data compression parameter based on power availability. When battery capacity is sufficient, compression is minimal (high quality); when capacity drops below threshold, compression ratio increases (lower quality), thus extending operating time while minimizing quality loss
3Reliability
If the monitoring system maintains constant high quality data transmission, then the data quality is preserved, but the power consumption increases and may cause interruptions when energy is insufficient
Solution Approach 1:
The patent implements dynamic adaptation of transmission quality to power conditions. The system monitors battery capacity and adjusts image quality settings in real-time, ensuring service continuity by preventing power depletion while maintaining acceptable quality levels based on available energy
Solution Approach 2:
The system changes the data quality parameter based on power status to ensure reliable operation. When power is abundant, high quality is maintained; when power becomes insufficient, quality is reduced to prevent interruptions, thus ensuring overall service continuity and reliability

AI summary
A data processing apparatus (14) according to an embodiment includes a data processing unit (105) and a wireless unit (104). The wireless unit receives the data converted by the data processing unit and wirelessly transmits the input data to an access point. The data processing unit converts, when a remaining amount input from a battery (12) is in a first state, the input data with a first setting and outputs the converted data to the wireless unit. The data processing unit converts, when the remaining amount of the battery is in a second state different from the first state, the input data with a second setting and outputs the converted data to the wireless unit. A capacity per unit time of the data after conversion is different between the first setting and the second setting.
