Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicles face limitations in installing electric components in the region below the windshield due to waste heat buildup, which restricts the number of components that can be installed and exposes them to undesirable environmental influences.
Innovation Solution
A motor vehicle design with a unit area divided into a cold region and a warm region, utilizing air inlets and outlets to create a cooling system that separates heat-emitting components from temperature-critical ones, with a battery housing featuring integrated air flow ducts to manage heat and protect components from moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric components are installed in the unit area below the windshield, then the functionality of the vehicle is improved, but waste heat buildup occurs and the number of installable components is limited
Solution Approach 1:
The unit area is divided into a cold region and a warm region by a partition. The warm region accommodates heat-emitting electric components, while the cold region houses temperature-sensitive components. This segmentation allows multiple components to be installed simultaneously without thermal interference, resolving the contradiction between increasing component数量 and managing heat buildup.
2Adaptability or versatility
If heat-emitting electric components are installed in the unit area, then vehicle functionality is enhanced, but components become exposed to undesirable environmental influences such as moisture
Solution Approach 1:
The battery housing acts as an intermediary structure between the electric components and the external environment. It provides a sealed protective enclosure that isolates the components from moisture and environmental influences, while still allowing heat dissipation through the controlled air flow system with air entry and exit openings.
Solution Approach 2:
The harmful environmental factors (moisture, spray) are excluded from the unit area by sealing the battery housing and creating a controlled environment. The air flow system extracts heat from the components while preventing moisture ingress, effectively separating the thermal management function from environmental protection.
3Temperature
If air cooling is implemented for electric components, then heat removal is achieved, but the air conditioning system load increases and CO2 emissions rise
Solution Approach 1:
The electric components are equipped with self-service cooling capabilities through integrated air flow systems. Each battery housing has air entry and exit openings that allow natural or forced air circulation to pass through and cool the components directly, without requiring the vehicle's central air conditioning system. This autonomous cooling reduces the energy load on the air conditioning system and associated CO2 emissions.

Implementation Method 1
the air entering through the air inlet and emerging through the air outlet flows at least through the warm region
Implementation Method 2
the unit area is divided into at least one cold region and at least one warm region sealed off from the cold region by a partition

AI summary
A motor vehicle has a unit area which is arranged inside the motor vehicle body. The unit area has at least one air inlet and at least one air outlet. The unit area is divided into at least one cold area and at least one warm area which is isolated from the cold area by a separating wall. The warm area accommodates at least one unit emitting heat and the air emerging from the air outlet and entering into the air inlet flows through at least the warm area.
