Image Capture Apparatus Thermal Management via Recording Media Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power consumption of image capturing apparatuses leads to higher temperatures, reducing the time period for photographing moving images, as both the image capturing device and image processing engine generate heat, and the recording medium's heat dissipation is inadequate, potentially causing local temperature rises.
Innovation Solution
The apparatus is designed with a control unit that strategically records image data of varying volumes in different recording media, with larger volume data recorded near the internal chassis for efficient heat dissipation and smaller volume data recorded farther away, utilizing a chassis for heat dispersion and minimizing heat transfer to the exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple recording media are used to extend the time period for photographing moving images, then the duration of action is improved, but local temperature rise occurs in the recording media causing reduction of the time period
Solution Approach 1:
The patent applies local quality by differentiating the positioning of recording media based on their functional characteristics. Recording media with higher heat generation (such as those used for high-quality video recording) are positioned closer to the chassis, while media with lower heat generation are positioned farther away. This spatial differentiation of thermal properties allows the system to manage heat locally and prevents uniform temperature rise across all recording media, thereby extending the operational time period.
Solution Approach 2:
The chassis serves as an intermediary element in the thermal management system. By positioning recording media close to the chassis, the patent utilizes the chassis as a heat sink and thermal conductor to dissipate heat from recording media. The chassis acts as a mediator between the heat-generating recording media and the surrounding environment, preventing local temperature rises and enabling extended operation.
2Temperature
If recording media are positioned close to the chassis for heat dissipation, then temperature control is improved, but the complexity of device configuration increases
Solution Approach 1:
The patent applies parameter changes by modifying the spatial parameter (positioning) of recording media relative to the chassis based on their thermal characteristics. Instead of a fixed uniform arrangement, the system dynamically adjusts the positioning parameter according to the heat generation characteristics of different recording media. This parameter-based approach simplifies the overall configuration by establishing clear design rules rather than requiring complex active thermal management systems.

AI summary
An image capturing apparatus that increases time over which a moving image can be photographed by reducing the influence of heat generated in the apparatus. An image processing circuit performs predetermined processing on a moving image captured by an image capturing device. A plurality of recording media are arranged inside a grip portion for gripping an apparatus body. An internal casing ensures strength of the apparatus, and a system control circuit controls the apparatus. When moving image data formed by the image processing circuit using the captured moving image in a plurality of recording modes are recorded in the plurality of recording media, the system control circuit causes image data having a large volume to be recorded in a recording medium close to the internal casing and image data having a small volume to be recorded in a recording medium far from the internal casing.
