Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed target cooling temperature is set for the battery, then the cooling control is simplified and the device complexity is reduced, but the deterioration prevention effect of the battery cannot be achieved in varying climatic regions
Solution Approach 1:
The patent applies dynamics by making the target cooling temperature variable rather than fixed. The control device dynamically adjusts the target cooling temperature based on climate region information and user preferences, allowing the system to adapt to different environmental conditions while maintaining manageable complexity through automated control logic.
Solution Approach 2:
The patent changes the parameter of target cooling temperature from a fixed value to a variable value that can be adjusted based on climate region and user settings. This parameter change enables the system to optimize battery deterioration prevention for different regions without requiring complex hardware modifications.
2Reliability
If a variable target cooling temperature is set based on user input and region, then the deterioration prevention effect is optimized, but the device complexity increases
Solution Approach 1:
The control device performs multiple functions: it determines climate region information, receives user preferences, sets target cooling temperatures, and controls the cooling device. By consolidating these functions into a single control device, the system achieves optimized deterioration prevention without proportionally increasing overall system complexity.
Solution Approach 2:
The system provides self-service by automatically determining climate region information and adjusting target cooling temperatures based on user preferences without requiring manual intervention. This automation reduces the operational complexity for users while maintaining sophisticated control capabilities.
3Duration of action of stationary object
If the target cooling temperature is adjusted dynamically, then the battery lifespan is enhanced, but the electric power consumption increases
Solution Approach 1:
The patent adjusts the target cooling temperature parameter dynamically based on climate region and user preferences rather than maintaining a constantly low temperature. This parameter adjustment allows the system to extend battery lifespan by cooling the battery to appropriate temperatures for each region while reducing unnecessary cooling operations that would consume excessive electric power.

AI summary
A battery temperature adjustment system includes: a battery configured to store electric power from an external power source, and supply electric power to a motor as a drive source of a vehicle; a cooling device to which the electric power from the external power source and the electric power from the battery are selectively supplied and configured to cool the battery; and a control device configured to control the cooling device to lower a temperature of the battery to a target cooling temperature while the vehicle is stopped. The target cooling temperature is a variable value. The control device obtains a target set by a user, and sets the target cooling temperature based on the target.
