Window Air Conditioner Split Structure for Noise and Frame Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window-type air conditioners suffer from noise pollution due to the installation gap between the window and the frame, allowing external noise to enter the room, and lack effective insulation and adjustable coolant pipe solutions.
Innovation Solution
A window-type air conditioner design featuring a spiral-shaped coolant pipe with a bellows structure and adjustable interval between the outdoor and indoor modules, including a coil spring for stress reduction and a temporary support portion for installation, which provides insulation and prevents coolant leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the window-type air-conditioner is installed on a window frame, then installation ease is improved, but noise transmission from external to indoor increases
Solution Approach 1:
The outdoor module containing the noise-generating compressor is extracted and separated from the indoor module, placing it on the outdoor side of the window frame. This physical separation removes the noise source from the indoor environment while maintaining the air-conditioning function through the window frame installation.
Solution Approach 2:
The air-conditioner is divided into two distinct modules: an indoor module for cooling/heating and an outdoor module for compression and heat exchange. This segmentation allows the noisy outdoor components to be isolated from the indoor space while the indoor module remains installed within the window frame for ease of installation.
2Stability of the object's composition
If the interval between indoor and outdoor modules is fixed, then structural stability is improved, but adaptability to different window frame thicknesses deteriorates
Solution Approach 1:
The connection structure between indoor and outdoor modules is made adjustable rather than fixed. The support rod's length can be modified, and the connecting structure includes adjustable components that allow the interval between modules to be dynamically changed to match different window frame thicknesses while maintaining structural stability during operation.
Solution Approach 2:
The physical parameters of the connection structure, specifically the length of the support rod and the interval between modules, are made variable. This allows the system to adapt to different installation conditions (different window frame thicknesses) by changing these parameters while maintaining structural integrity through proper connection mechanisms.
3Manufacturing precision
If a rigid coolant pipe is used, then manufacturing precision is improved, but adaptability to adjustable intervals deteriorates
Solution Approach 1:
The coolant pipe is designed with flexible characteristics, allowing it to bend and adjust to different intervals between indoor and outdoor modules. This flexibility is achieved while maintaining the pipe's structural integrity and manufacturing precision through controlled material selection and design, enabling the pipe to accommodate variable installation conditions.
Solution Approach 2:
The coolant pipe transitions from a rigid, fixed-length component to a flexible, adjustable-length component that can adapt to different intervals between modules. This dynamic characteristic allows the same pipe design to work across various installation scenarios while maintaining proper coolant flow and connection reliability.
