Solution Overview
Problem
Climate systems in vehicles, particularly working machines, face challenges in space constraints due to bulky air ducts, which obstruct operator visibility and are difficult to install and service.
Innovation Solution
A climate system utilizing a thin, flexible air conduit with a pressurized air source that compresses air to a high pressure, allowing for a smaller cross-sectional area and easier routing, along with a nozzle for air speed reduction and heat exchangers for temperature control, enabling reduced space usage and improved installation and servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional air ducts are used in the climate system, then air can be supplied to the cab, but the ducts consume large space and obstruct operator visibility
Solution Approach 1:
The patent applies pneumatic principles by using a pressurized air source to deliver compressed air through a thin conduit to the cab. The compressed air is expanded at the outlet to provide sufficient airflow for climate control. This pneumatic approach replaces traditional bulky air ducts with a thin, flexible conduit that consumes minimal space and does not obstruct operator visibility, while still delivering adequate air flow to the cab.
2Ease of manufacture
If traditional air ducts are used in the climate system, then air can be supplied to the cab, but the ducts are difficult to install and service
Solution Approach 1:
The patent employs a thin, flexible conduit instead of rigid air ducts. This flexible conduit can be easily routed through narrow spaces and around obstacles within the vehicle, simplifying installation. The thin-walled construction makes the conduit lightweight and adaptable to various routing configurations. For servicing, the flexible nature allows for easier removal and reinstallation compared to traditional rigid ductwork, reducing service complexity.
3Volume of moving object
If a thin conduit is used to supply air to the cab, then space is minimized and visibility is improved, but the conduit requires high pressure to maintain adequate air flow
Solution Approach 1:
The patent utilizes parameter changes by compressing air to high pressure at the source, transporting it through the thin conduit, and then expanding it at the outlet end within the cab. This pressure transformation allows the system to overcome the limitations of the thin conduit's small cross-sectional area, maintaining adequate air flow velocity and volume despite the reduced conduit size. The high pressure enables the thin conduit to deliver sufficient air for climate control while minimizing space consumption.
