Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling type air conditioners take a long time to reach target temperatures, have limited airflow distance, and cause unpleasant drafts due to uneven temperature distribution, leading to user dissatisfaction.
Innovation Solution
A ceiling type air conditioner with dual vanes that adjust angles to direct airflow horizontally and vertically, using a controller to optimize airflow patterns based on cooling or heating operations, and a fan speed adjustment system to minimize drafts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the air conditioner uses conventional single-direction airflow discharge, then the structure is simple, but the time to reach target temperature is long and the airflow distance is limited
Solution Approach 1:
The discharge vane is divided into multiple independent segments (first discharge vane and second discharge vane) that can rotate independently. Each segment controls airflow in different directions, enabling the system to discharge air both horizontally and vertically simultaneously, thereby increasing airflow distance and speed without requiring a completely complex new structure
Solution Approach 2:
The discharge vanes are made dynamically adjustable through motor-driven rotation mechanisms. The vanes can change their angles and positions based on operational requirements (cooling vs. heating modes), allowing the system to optimize airflow patterns dynamically rather than being fixed in a single configuration
2Productivity
If the air conditioner uses the same control method for both cooling and heating operations, then the control system is simple, but the indoor temperature reaches target temperature slowly and user comfort is reduced
Solution Approach 1:
The control system changes operational parameters (vane angles, rotation directions, airflow distribution ratios) based on the operational mode (cooling or heating). In cooling mode, vanes are positioned to maximize horizontal airflow; in heating mode, they are adjusted for vertical airflow patterns, thereby significantly improving temperature adjustment speed without requiring hardware changes
3Length of stationary object
If the air conditioner discharges air in a single direction, then the device structure is simple, but the airflow distance is limited and cannot reach user activity areas
Solution Approach 1:
The airflow discharge is extended from a single horizontal dimension to two dimensions by adding vertical airflow capability. The first discharge vane handles horizontal airflow while the second discharge vane handles vertical airflow, creating a three-dimensional airflow pattern that significantly extends the effective airflow distance to reach user activity areas
4Ease of operation
If the air conditioner uses conventional airflow control, then the control method is simple, but draft phenomena occur causing user discomfort
Solution Approach 1:
The airflow control system applies different control strategies to different locations and conditions. The control unit adjusts vane positions and airflow distribution based on operational mode (cooling/heating) and environmental conditions, creating locally optimized airflow patterns that prevent draft phenomena in user activity areas while maintaining overall system simplicity

AI summary
A method of controlling a ceiling type air conditioner including a panel, a first vane group, and a second vane group, and each of the first and second vane groups including an upper discharge vane and a lower discharge vane includes performing first mixing operation in which the first vane group guides air in a direction close to the ceiling surface to form horizontal airflow and the second vane group guides air in a direction close to a floor surface to form vertical airflow, determining whether swing operation of continuously rotating the first vane group and the second vane group or fixing operation in which the first vane group and the second vane group are located at the same angle is performed, and performing second mixing operation in which the first vane group forms the vertical airflow and the second vane group forms the horizontal airflow.
