Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window type air conditioners installed on window frames can cause discomfort due to external noise, such as compressor noise, entering the room through gaps between the window and frame.
Innovation Solution
A window type air conditioner design with an outdoor module, indoor module, and connection support module that includes a first connection rod with a sealing member to form a seal between the refrigerant pipe and the connection rod, reducing noise and vibration transfer between modules.
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 from external sources enters the room through gaps between the window and frame
Solution Approach 1:
A connection support module is introduced as an intermediary component between the indoor and outdoor modules. This module includes a connection rod with a sealing member that prevents noise transmission through the connection path, while still allowing the air conditioner to be installed on the window frame structure.
Solution Approach 2:
The sealing function is extracted as a separate component (sealing member) from the connection structure. The sealing member is specifically designed to prevent noise entry through gaps, while the connection rod provides the structural connection between modules.
2Device complexity
If the refrigerant pipe is directly connected to the connection rod, then device complexity is reduced, but dissimilar metal corrosion occurs between different metal materials
Solution Approach 1:
A sealing member made of non-metallic material (such as rubber or polymer) is introduced as an intermediary between the metal refrigerant pipe and the metal connection rod. This sealing member prevents direct contact between dissimilar metals, thereby preventing galvanic corrosion, while still allowing the connection to function.
Solution Approach 2:
The connection structure uses composite materials by combining metal components (connection rod, refrigerant pipe) with non-metallic sealing materials. This composite approach allows the structure to maintain structural integrity while preventing corrosion through material incompatibility.
3Object-affected harmful factors
If the gap between window and frame is sealed to prevent noise, then noise reduction is improved, but the connection between indoor and outdoor modules becomes more complex
Solution Approach 1:
The connection support module serves multiple functions simultaneously: it provides structural connection between indoor and outdoor modules, seals gaps to prevent noise transmission, and accommodates the refrigerant pipe passage. By integrating these functions into a single module, the overall complexity is managed despite the added sealing capability.
Solution Approach 2:
The connection function and sealing function are merged into a single connection support module. The connection rod with integrated sealing member combines structural support and noise prevention in one component, reducing the number of separate parts needed.

Function Achieved in This Case
The design effectively minimizes noise and vibration transfer from the outdoor module to the indoor module, enhancing user comfort by sealing gaps and preventing dissimilar metal corrosion.
Implementation Method 1
the sealing member is arranged between the outer circumferential surface of the refrigerant pipe and the inner circumferential surface of the first connection rod to form a seal between the refrigerant pipe and the first connection rod
