Outdoor Unit Antenna Integration for Damage-Free AC Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor air conditioner units face issues with antenna exposure leading to damage and limited installation space, as well as poor aesthetics and reduced transmission/reception sensitivity due to antenna placement.
Innovation Solution
The antenna is integrated into the case of the outdoor air conditioner unit, using a base made of insulating material with a conductive transmission/reception member, allowing for internal placement and improved signal sensitivity without increasing the unit's size or interfering with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is exposed to the outside of the outdoor unit, then the transmission/reception sensitivity is improved, but the antenna is damaged during installation or movement and the aesthetics are poor
Solution Approach 1:
The antenna is nested within the outdoor unit case, specifically embedded in the side surface of the case. The antenna includes a base made of insulating material and a transmission/reception member made of conductive material disposed in the base, creating a nested structure that protects the antenna while maintaining functionality
Solution Approach 2:
The insulating material base acts as an intermediary between the conductive transmission/reception member and the metal case, preventing direct contact that would cause signal interference while providing mechanical support and protection
2Reliability
If the antenna protrudes to the outside of the outdoor unit, then the transmission/reception sensitivity is improved, but the installation location is limited and a larger space is required
Solution Approach 1:
The antenna is nested within the side surface of the case, utilizing the existing outer shell space rather than requiring additional protruding space. This allows the antenna to be positioned on the side surface without increasing the overall footprint of the outdoor unit
Solution Approach 2:
Instead of placing the antenna on the top surface or having it protrude vertically, the antenna is positioned on the side surface of the case, utilizing a different spatial dimension and orientation to achieve signal transmission without increasing the required installation space
3Object-affected harmful factors
If the antenna is embedded in the case, then the antenna is protected from damage and installation is easier, but the transmission/reception sensitivity may be reduced
Solution Approach 1:
The insulating material base serves as an intermediary that allows the antenna to be embedded in the metal case while preventing signal interference. The base provides mechanical embedding for protection while its insulating properties maintain signal transmission/reception sensitivity
Solution Approach 2:
The case is designed with local quality variations - the antenna is disposed in a specific location on the side surface with a receiving groove, and the insulating material is applied specifically at the antenna location to enable embedding without compromising overall case integrity or signal performance

AI summary
An outdoor unit of an air conditioner may include a case that forms an outer shape of the outdoor unit; a controller that is disposed inside of the case and controls operation of various components of the air conditioner; a heat dissipation member connected to the controller to dissipate heat generated by the controller; and a support member that is coupled with the heat dissipation member to fix a position of the heat dissipation member, and having an insertion hole into which the heat dissipation member is inserted. The heat dissipation member is disposed to face the controller with respect to the support member, and at least a partial area of the heat dissipating member penetrates the insertion hole to prevent damage to a structure that dissipates heat of the controller to the outdoor unit of the air conditioner that is in contact with the controller.
