Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture apparatuses experience excessive temperature increases when supplied with higher system voltage, leading to potential operation stops due to inefficient voltage conversion, which existing USB Power Delivery (USB PD) specifications fail to adequately address.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If higher supply voltage is used from power supply apparatus, then power delivery capability is improved, but temperature increase and conversion loss worsen
Solution Approach 1:
The patent implements dynamic voltage adjustment by continuously monitoring temperature and power consumption, then negotiating with the power supply apparatus to adjust supply voltage in real-time. This resolves the contradiction by making the voltage level adaptive rather than static, allowing high voltage when cool and low voltage when hot.
Solution Approach 2:
The patent changes the voltage parameter dynamically based on temperature and power consumption conditions. By monitoring these parameters and adjusting supply voltage accordingly, the system optimizes power delivery while preventing excessive temperature rise, directly resolving the contradiction between power capability and thermal management.
2Power
If higher supply voltage is used from power supply apparatus, then power delivery capability is improved, but conversion loss increases
Solution Approach 1:
The system dynamically adjusts supply voltage based on real-time monitoring of power consumption and temperature, negotiating with the power supply apparatus to optimize voltage levels. This dynamic approach minimizes conversion loss by matching supply voltage to actual device needs rather than using fixed high voltage.
Solution Approach 2:
The patent changes supply voltage parameters dynamically based on power consumption measurements. By adjusting voltage to match actual power needs, the system reduces unnecessary conversion loss while maintaining adequate power delivery capability.
3Device complexity
If supply voltage is not adjusted based on temperature, then power delivery is simplified, but operation reliability deteriorates
Solution Approach 1:
The patent implements feedback control by monitoring temperature and power consumption, then using this information to negotiate voltage adjustments with the power supply apparatus. This feedback mechanism ensures reliable operation under varying thermal conditions while maintaining a relatively simple overall system architecture.

AI summary
An image capture apparatus includes a determination unit that determines voltage to be supplied from a power supply apparatus to the image capture apparatus, based on a temperature of the image capture apparatus and power consumption of the image capture apparatus; a communication unit that sends the determined voltage to the power supply apparatus; and a power receiving unit that receives power supplied from the power supply apparatus to the image capture apparatus after the determined voltage is sent to the power supply apparatus.
