Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular battery units face challenges in effectively cooling battery modules and preventing moisture from damaging the batteries, with current designs often leading to uneven cooling and potential moisture accumulation that can degrade battery performance.
Innovation Solution
A vehicular battery unit design featuring a hollow frame with a drain hole connecting to the interior and a downward-extending drain pipe to manage moisture and enhance cooling efficiency, where the hollow frame reinforces the battery unit body and directs water away from the batteries, and a heat exchange panel system that ensures uniform air flow for cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is placed in a recess with support above the bottom surface, then the battery is prevented from being immersed in water, but moisture can still accumulate in the recess and potentially damage the battery
Solution Approach 1:
The patent extracts the harmful moisture from the recess by providing a drain outlet that allows water to be discharged from the recess. The check valve is installed at the drain outlet to control the drainage direction, extracting moisture effectively while preventing water immersion damage to the battery.
Solution Approach 2:
The check valve acts as an intermediary device between the recess interior and exterior. It mediates the drainage process by allowing water to flow out from the recess while preventing reverse flow, thus protecting the battery from moisture accumulation without compromising the battery's positional stability in the recess.
2Object-affected harmful factors
If a check valve is provided at the drain outlet to permit only drainage outside the vehicle, then moisture is discharged effectively, but the structure becomes more complex
Solution Approach 1:
The check valve is designed to function automatically based on the pressure difference between the interior and exterior of the recess. When water accumulates in the recess, the pressure differential automatically opens the check valve to allow drainage, and when drainage is complete, the valve closes automatically. This self-service mechanism eliminates the need for external control systems, reducing overall device complexity while maintaining effective moisture discharge.
3Strength
If the battery unit body is reinforced with additional structures, then structural strength is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The hollow frame serves multiple functions simultaneously: it reinforces the battery unit body to improve structural strength, provides a pathway for the drain pipe to extend through, and supports the overall drainage system. This multi-functionality reduces the need for separate reinforcing structures, thereby reducing device complexity and manufacturing difficulty while maintaining improved strength.

Function Achieved in This Case
The solution provides effective cooling for battery modules by ensuring uniform air flow and prevents moisture damage by directing water away from the batteries, enhancing durability and performance while reducing the complexity of the structure.
