Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to provide an image capturing apparatus capable of forced air cooling without increasing the size or weight of the main body, which is necessary for high-definition video capture, while maintaining high rotational acceleration for pan and tilt operations.
Innovation Solution
The apparatus includes a camera unit rotatably supported by a first and second unit, with a heat dissipation unit having inlet and exhaust ports, and protrusion portions for efficient heat dissipation, utilizing air flow through a duct system to dissipate heat generated by substrates without enlarging the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation unit for forced air cooling is installed in the pan base unit, then heat dissipation performance is improved, but the weight of the pan base unit increases and rotational acceleration decreases
Solution Approach 1:
The heat dissipation unit is extracted from the pan base unit and relocated to the main body of the image capturing apparatus. This separation removes the heavy cooling components from the moving pan base, improving rotational acceleration while maintaining heat dissipation functionality through a dedicated cooling path from the substrate to the main body's heat dissipation unit.
Solution Approach 2:
A heat dissipation path (thermal conduction path) is introduced as an intermediary between the substrate and the heat dissipation unit. This path efficiently transfers heat from the substrate to the main body's heat dissipation unit, enabling effective heat removal without requiring the heat dissipation unit to be physically attached to the pan base unit.
2Power
If a substrate with high power consumption is disposed on the pan base, then high-definition video capture capability is improved, but heat dissipation becomes difficult without increasing the main body size
Solution Approach 1:
The heat dissipation function is extracted from the pan base unit and centralized in the main body. This allows the substrate to be placed on the pan base for high power consumption applications while the heat is conducted through a thermal path to the main body's heat dissipation unit, avoiding the need to enlarge the main body for additional cooling components.
Solution Approach 2:
A thermal conduction path serves as an intermediary mechanism that bridges the substrate on the pan base and the heat dissipation unit in the main body. This intermediary path enables efficient heat transfer from high power consumption components without requiring the heat dissipation unit to be located adjacent to the substrate, thus maintaining compact main body dimensions.
