Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large structural size of window air conditioners poses a challenge for installation, making it difficult to popularize this type of air conditioner due to increased installation complexity.
Innovation Solution
A window air conditioner design featuring a casing with an indoor housing lower than an outdoor housing, creating an avoiding groove to accommodate the window edge, allowing for a compact structure that enhances installation simplicity and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the structural size of the window air conditioner is increased, then the installation difficulty increases, but the heat exchange efficiency may be improved
Solution Approach 1:
The patent applies dimensional change by creating an avoiding groove in the housing that extends in the depth direction (third dimension) to accommodate the window edge. This allows the air conditioner to fit into the window opening without increasing its width or height, thereby maintaining ease of installation while preserving the necessary heat exchange surface area through the outdoor heat exchanger configuration.
Solution Approach 2:
The housing is segmented into distinct functional zones: an indoor housing portion, an outdoor housing portion, and an avoiding groove portion. This segmentation allows each component to be optimized independently - the heat exchangers can be sized appropriately for heat exchange efficiency while the avoiding groove handles the installation constraint by accommodating the window edge.
2Ease of operation
If the structural size is reduced for easier installation, then the air inlet area for the outdoor heat exchanger may be limited
Solution Approach 1:
The avoiding groove utilizes the depth dimension of the housing to accommodate the window edge, which allows the front face of the outdoor housing to maintain a larger area for the air inlet. This dimensional strategy enables the air inlet area to remain sufficient for heat exchange performance while the overall structure remains compact enough for easy installation.
Solution Approach 2:
The housing exhibits asymmetric design where the avoiding groove is positioned specifically to accommodate the window edge configuration. This asymmetric feature allows the air inlet area to be optimized independently from the installation constraints, as the groove is strategically placed to resolve the window edge issue without compromising the air inlet dimensions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact design facilitates easier installation, improves heat exchange efficiency, and enhances overall performance by allowing a larger air inlet area for the outdoor heat exchanger, resulting in better indoor environment control.
Implementation Method 1
The indoor fan assembly is configured to deliver indoor air to the indoor heat exchanger for heat exchange
Implementation Method 2
The outdoor fan assembly is configured to deliver outdoor air to the outdoor heat exchanger for heat exchange
Implementation Method 3
indoor heat exchanger for heat exchange and then output the air back indoors

AI summary
A window air conditioner includes a casing, an indoor heat exchanger, an indoor fan assembly, an outdoor heat exchanger and an outdoor fan assembly. The casing includes a base, an indoor housing and an outdoor housing; the indoor heat exchange, the indoor fan assembly, the outdoor heat exchanger and the outdoor fan assembly are arranged on the base. A top of the indoor housing is lower than a top of the outdoor housing, and an avoiding groove recessed towards the base is formed between the indoor housing and the outdoor housing.
