Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing apparatuses face challenges in efficiently dissipating heat generated by components like image processing circuits and image sensors while maintaining a compact size, leading to performance degradation and user discomfort due to heat buildup.
Innovation Solution
The apparatus incorporates a duct unit with a duct base and duct plate arranged obliquely to the main circuit board, coupled with a cooling fan, to efficiently dissipate heat through forced air-cooling, while optimizing space usage by angling the fan and heat sinks to minimize size increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a forced air-cooling method with cooling fan and air-cooling duct is used to discharge heat from the image capturing apparatus, then heat dissipation efficiency is improved, but the size of the image capturing apparatus body increases
Solution Approach 1:
The cooling fan is mounted obliquely to the optical axis direction rather than parallel to it, utilizing three-dimensional space more effectively. The duct plate is also disposed obliquely to the duct base, creating an angled air flow path that reduces the overall footprint of the cooling system in the optical axis direction, thereby reducing apparatus size while maintaining heat dissipation efficiency
Solution Approach 2:
The air flow path is designed to dynamically adapt to the compact structure by using the oblique arrangement of the duct plate and cooling fan. This angular configuration allows the air flow to efficiently traverse the heat generating devices and exit through the air outlet in a more space-efficient manner, achieving effective heat dissipation in a reduced volume

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves both effective heat dissipation and size reduction by utilizing angled ducts and fans, maintaining performance and user comfort by reducing internal temperatures.
Implementation Method 1
a cooling fan that draws outside air into the duct unit
Implementation Method 2
heat generated in the image capturing apparatus is transferred to the drawn air to discharge the warmed air to the outside
