Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate fan is added to cool the heat generation part, then the cooling effectiveness is improved, but the device weight and complexity increase
Solution Approach 1:
The patent merges the cooling functions for the sensor module and heat generation part into a single integrated cooling system. The first fluid passage cools the heat radiation part while the second fluid passage cools the heat generation part, and these passages are connected through a merging part that allows fluid communication. This eliminates the need for separate fans while maintaining effective cooling of both components.
Solution Approach 2:
The single fan in the patent serves multiple cooling functions by circulating fluid through both the first fluid passage (cooling the sensor module via heat radiation part) and the second fluid passage (cooling the heat generation part). This multi-functional approach reduces the number of components needed while achieving comprehensive cooling coverage.
2Temperature
If additional cooling components are added to cool the heat generation part, then the temperature control is improved, but the device size increases
Solution Approach 1:
The patent combines the cooling pathways for the sensor module and heat generation part into an integrated fluid circulation system. The first and second fluid passages are merged through a merging part, allowing a single cooling loop to serve both thermal management needs. This reduces the overall device volume compared to having completely separate cooling systems.
Solution Approach 2:
The merging part acts as an intermediary component that connects the first and second fluid passages. This mediator allows the cooling fluid to transition between the two cooling pathways, enabling efficient heat dissipation from both the sensor module and heat generation part through a unified system architecture.
3Volume of moving object
If the camera is made compact by reducing components, then the portability is improved, but the cooling capability may be insufficient
Solution Approach 1:
The single fan in the compact camera design performs multiple cooling functions by circulating fluid through both the first fluid passage (for sensor module cooling via heat radiation) and the second fluid passage (for heat generation part cooling). This multi-functional component maintains adequate cooling capability while minimizing the number of parts.
Solution Approach 2:
The patent merges the cooling functions for two distinct thermal management needs into a single integrated system. The first and second fluid passages are connected through a merging part, creating a compact unified cooling system that maintains adequate cooling capability for both the sensor module and heat generation part without requiring additional separate cooling components.

AI summary
This camera (10) comprises a sensor module (1) that measures radiation data, heat dissipating units (14-1 to 14-2) that dissipate heat generated by cooling the sensor module (1), an electric device (20), and fans (15-1 to 15-2) that generate flow of a first fluid that cools the heat dissipating units (14-1 to 14-2). Furthermore, a first channel (41) in which the first fluid flows, a second channel (43) in which a second fluid that cools the electric device (20) flows, and a merging section (44) that draws in, from the second channel (43), the second fluid into the first channel (41) by using the flow of the first fluid are formed. This type of camera (10) can be formed to be smaller compared to other cameras that are further provided with a fan to cause the second fluid to flow in the second channel (43).
