Solution Overview
Problem
Ceiling-type air conditioners face challenges with blade maintenance, noise, vibration, and limited air discharge methods, requiring an easily detachable, maintainable, and quiet blade solution that can operate at minimal wind speed for user comfort.
Innovation Solution
An air conditioner design featuring a rotatable blade with an elastic member and a blade driving member, where the elastic member is coupled to the blade driving member to reduce noise and vibration, and includes a polygonal pillar shape for secure fitting, allowing easy separation and reattachment for maintenance, and multiple air discharge holes for efficient air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blade is firmly fixed to the blade driving member, then the reliability of power transmission is improved, but the ease of maintenance and repair deteriorates
Solution Approach 1:
The connection between the blade and blade driving member is segmented into modular components: the blade with its insertion portion, the elastic member as a separate coupling element, and the blade driving member with its insertion hole. This segmentation allows the blade to be easily detached for maintenance while ensuring reliable power transmission when assembled, directly resolving the contradiction between firm fixation and ease of repair.
Solution Approach 2:
The elastic member changes its physical state between compressed and relaxed conditions to control the coupling strength. When compressed, it provides strong holding force for reliable power transmission; when released, it allows easy detachment for maintenance. This parameter change enables the system to switch between the two opposing requirements dynamically.
2Strength
If a rigid connection structure is used between blade and blade driving member, then the structural strength is improved, but the noise and vibration increase
Solution Approach 1:
The elastic member acts as a flexible coupling element between the blade and blade driving member. It provides sufficient connection strength while absorbing vibrations and reducing noise through its elastic deformation, directly addressing the contradiction between structural strength and harmful vibrations.
Solution Approach 2:
The elastic member serves as an intermediary element between the rigid blade and the blade driving member. It mediates the power transmission while isolating the harmful effects of rigid connection such as noise and vibration, maintaining both strength and comfort.
3Ease of manufacture
If a simple blade structure is used, then the ease of manufacture is improved, but the air discharge efficiency deteriorates
Solution Approach 1:
The blade structure incorporates multiple air discharge holes at specific locations to optimize air distribution efficiency. This localized modification maintains the overall simplicity of the blade structure for easy manufacturing while significantly improving air discharge performance through strategic hole placement and configuration.
