Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling type air conditioners with circular shapes face issues in controlling air flow angles due to structural defects, leading to inefficient air distribution, difficulty in inducing both horizontal and vertical air flows, and performance degradation from re-absorbed air during heating operations.
Innovation Solution
A ceiling-mounted air conditioner with a modular design featuring a liftable or rotatable air guide module that adjusts the flow path of the circular cassette to precisely control air flow angles, allowing for horizontal and vertical air flow induction and preventing air return, using a motor-powered pinion and rack gear system to facilitate operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a ring-shaped integrated discharge port is used to discharge air evenly in all directions, then air distribution uniformity is improved, but air flow control precision deteriorates due to gap formation at central portion and omission of vane
Solution Approach 1:
The discharge port is divided into multiple independent discharge vanes (first discharge vane, second discharge vane, etc.) arranged radially around the central axis. Each vane can be independently controlled to adjust air flow direction, eliminating the gap formation problem of integrated ring-shaped ports while maintaining 360-degree air distribution capability.
Solution Approach 2:
The discharge vanes are made rotatable around the central axis through a driving mechanism (motor, gear, etc.), enabling dynamic adjustment of air flow angles. This allows the system to switch between horizontal air flow mode (cooling) and vertical air flow mode (heating) by rotating the vanes to different positions, achieving precise air flow control.
2Shape
If a circular air conditioner structure is used, then aesthetic appearance and compact design are improved, but air flow control capability deteriorates due to difficulty in inducing both horizontal and vertical air flows
Solution Approach 1:
The circular cassette structure incorporates rotatable discharge vanes that can dynamically adjust their orientation. In cooling mode, the vanes are positioned to induce horizontal air flow for indirect air delivery. In heating mode, the vanes rotate to induce vertical air flow to prevent air return, enabling the circular structure to adapt to different operational requirements.
Solution Approach 2:
The same circular discharge port structure serves multiple functions: it can discharge air horizontally for cooling operations and vertically for heating operations. The multi-functionality is achieved through the rotatable discharge vanes that redirect air flow based on operational mode, eliminating the need for separate structures for different functions.
3Ease of manufacture
If the discharge port structure is simplified to circular shape, then manufacturing complexity is reduced, but air flow performance deteriorates due to weak flow re-absorption at corner of discharge port during heating operation
Solution Approach 1:
The circular discharge port is segmented into multiple discharge vanes with optimized geometries. The vanes are positioned and shaped to prevent weak flow re-absorption at corners during heating operations. Each vane can be independently optimized for its specific function while maintaining the overall circular aesthetic and manufacturing simplicity.
