Vehicle AC Intake Layout With Soundproofed Engine-Room Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air conditioners installed in the interior of vehicles face challenges in securing space due to their arrangement, limiting spatial usability and passenger convenience, and are prone to noise and contamination from the engine room.
Innovation Solution
The air conditioner is redesigned with an intake unit installed in the engine room, covered by a case cover and soundproofing member, and features a filter extractor for easy air filter replacement, minimizing interior components and enhancing noise isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air conditioner is installed in the interior of the vehicle, then the air conditioner can be easily accessed and maintained, but the interior space is reduced and spatial usability is limited
Solution Approach 1:
The intake unit is extracted from the interior space and relocated to the engine room. This separation allows the air conditioner to be installed in a location that does not encroach on passenger space, while the filter extractor mechanism maintains ease of access for maintenance operations through the engine room.
Solution Approach 2:
The air conditioner system is segmented into distinct functional units: the intake unit with filter is separated and placed in the engine room, while the main air conditioner body remains in the interior. This segmentation allows each component to be optimally positioned for its specific function without compromising overall system performance or interior space utilization.
2Area of stationary object
If the intake unit is installed in the engine room, then interior space is maximized, but noise from the engine room can enter the interior
Solution Approach 1:
A soundproofing member is introduced as an intermediary element between the intake unit in the engine room and the interior space. This soundproofing member blocks noise transmission from the engine room to the interior while allowing the intake unit to function normally in its relocated position.
Solution Approach 2:
The soundproofing member acts as a flexible barrier that isolates the intake unit from the interior acoustic environment. This thin film or shell structure effectively attenuates noise transmission while maintaining the functional integrity of the air intake system.
3Device complexity
If the air filter is installed inside the intake unit in the engine room, then the air conditioning system is compact, but the air filter is difficult to access and replace
Solution Approach 1:
The filter extractor mechanism enables the air filter to be easily removed and replaced by the user through the engine room without requiring disassembly of the intake unit or specialized tools. This self-service capability maintains system compactness while dramatically improving maintenance accessibility.
Solution Approach 2:
The filter extractor provides a dynamic access mechanism that allows the air filter to be easily removed and reinstalled. This dynamic extraction capability transforms the static, hard-to-reach filter into a maintainable component that can be quickly serviced through the engine room opening.

AI summary
Proposed is a vehicle air conditioner, which performs cooling and heating by supplying cold air and hot air in an interior of the vehicle. The vehicle air conditioner includes an intake unit installed at an engine room and configured to suction and blows internal and external air to the interior, a heat exchanger unit configured to cool or heat and supply air blown from the intake unit, a case cover installed on an outer surface of the intake unit to cover the intake unit, and a case soundproofing member installed between an intake case of the intake unit and the case cover and configured to block noise that is transmitted to the intake case from the outside of the case cover.
