Duct Air Conditioner Fan Mounting With Impact-Load Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Duct type air conditioners face deformation and shaft deviation issues during transport or handling due to impact loads from motor weight, as existing designs lack adequate support mechanisms to absorb such loads effectively.
Innovation Solution
The design incorporates spacers mounted between motor supports and the top or bottom plates, featuring contact surfaces with positioning means such as protrusions and holes to regulate positional deviation and distribute impact loads, thereby preventing deformation of motor supports and fan panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the motor is mounted directly to the fan panel using a motor support, then the structure is simple and easy to manufacture, but the motor support or fan panel deforms under impact load during transport causing shaft deviation
Solution Approach 1:
The patent introduces a spacer as an intermediary component between the motor support and the top plate. This spacer acts as a mediator that absorbs impact loads during transport, preventing direct transmission of shock forces to the motor support and fan panel. The spacer includes positioning protrusions that fit into corresponding holes to maintain precise motor shaft alignment while cushioning against deformation.
2Stability of the object's composition
If the motor support is designed to hold the motor securely, then the motor is firmly fixed, but the motor support becomes vulnerable to deformation under impact load
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing spacers between the motor support and the top plate before transport. These spacers are specifically designed to cushion against impact loads that may occur during shipping or handling. The spacers absorb shock forces before they can deform the motor support, thereby maintaining both stability and strength under impact conditions.
3Device complexity
If no additional support components are added, then the device complexity is low, but impact loads cause motor shaft deviation and fan panel deformation
Solution Approach 1:
The patent segments the motor mounting system into distinct functional components: the motor support, the spacer, and the top plate. This segmentation allows the spacer to specifically address impact protection and positioning requirements without complicating the overall design. The spacer is further segmented with positioning protrusions that fit into holes, providing precise alignment functionality as an integrated but separable element.

AI summary
Even in the case of drop accident occurring due to a certain cause during transport or the like, it is intended by the present invention that any deformation of a motor support or a fan panel will not occur. A fan mechanism includes fan units having fan panels disposed vertically, motor supports mounted inwardly of said fan panels, motors mounted on said motor supports so that output shafts of the motors are parallel to the surfaces of the fan panels, fans positioned inwardly of said fan panels and driven by the motors, and spacers mounted to the motor supports so as to be positioned between the motor supports and a top plate or a bottom plate that serves as a bottom during conveyance.
