Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a forced air-cooling method using a cooling fan and air-cooling duct is used to discharge heat from the image capturing apparatus, then heat dissipation efficiency is improved, but the apparatus size increases
Solution Approach 1:
The cooling fan is mounted on the duct plate in an oblique direction rather than perpendicular to the duct base, utilizing three-dimensional spatial arrangement to achieve effective heat dissipation while minimizing the apparatus footprint. This angular mounting allows the air intake and exhaust paths to be optimized in multiple dimensions, resolving the contradiction between cooling efficiency and compact size
2Productivity
If heat generating devices are mounted on circuit boards in the image capturing apparatus, then functional performance is improved, but heat generation increases causing performance degradation and user discomfort
Solution Approach 1:
The patent converts the harmful heat generated by the image processing circuit and image sensor into a manageable thermal flow by designing a dedicated air-cooling duct system that channels airflow directly over the heat-generating components. The cooling fan creates a controlled air current that absorbs heat from the circuit boards and directs it outward, transforming the harmful thermal byproduct into a controlled heat transfer process that maintains device performance and user comfort

Function Achieved in This Case
This design achieves both effective heat dissipation and size reduction by utilizing a duct unit with angled components and a cooling fan, maintaining performance and user comfort.
Implementation Method 1
a cooling fan that draws outside air into the duct unit, wherein the duct unit comprises a duct base that is opposed to the main circuit board and is disposed substantially in parallel to the main circuit board
Implementation Method 2
heat generated in the image capturing apparatus is transferred to the drawn air to discharge the warmed air to the outside of the image capturing apparatus
