Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air cooling system is used to cool devices in mobile base station, then cooling capacity is limited by air conditioner size, but increasing air conditioner output increases electrical power consumption
Solution Approach 1:
The base station is divided into two separate areas: an indoor area containing temperature-sensitive devices (server device, wireless control device) cooled by liquid cooling, and an outdoor area containing the wireless device cooled by air cooling. This segmentation allows each area to use the most appropriate cooling method, reducing overall power consumption while effectively cooling all devices.
Solution Approach 2:
The patent introduces a liquid cooling device that circulates cooling liquid through heat exchangers attached to indoor devices. This hydraulic cooling system provides superior cooling efficiency compared to air cooling, enabling effective temperature control with lower power consumption for the same cooling capacity.
2Temperature
If outside air is introduced into vehicle cabin to cool devices, then cooling capacity increases, but dust or moisture enters and damages precision apparatuses
Solution Approach 1:
The base station is divided into an indoor area sealed against contaminants and an outdoor area exposed to outside air. The indoor area containing precision devices is protected from dust and moisture, while the outdoor area uses air cooling for the wireless device, thus achieving both cooling and protection.
Solution Approach 2:
A partition wall with a door serves as an intermediary barrier between the indoor and outdoor areas. This barrier allows controlled access while maintaining separation, preventing contaminants from the outdoor area from reaching the indoor precision devices.
3Adaptability or versatility
If multiple heat-generating devices are arranged in vehicle cabin, then base station functionality is achieved, but cooling capacity becomes insufficient
Solution Approach 1:
Devices are segmented into two groups based on their cooling requirements: indoor devices (server device, wireless control device) requiring liquid cooling are placed in the indoor area, while the wireless device can tolerate air cooling and is placed in the outdoor area. This segmentation enables effective cooling of multiple devices within the limited vehicle cabin space.
