Ceiling Recessed Fan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling recessed fans face challenges in achieving effective air output during cooling modes, as the air outlet design does not consider the internal structure of the fan, leading to poor air supply distance and comfort issues.
Innovation Solution
The proposed solution involves a ceiling recessed fan design where the air outlet assembly can be raised and lowered, forming a height difference with the main body frame to create an optimal air outlet. The air deflector's adjustable height and specific angle ranges ensure that the air output is parallel to the horizontal plane, enhancing air supply distance and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air outlet assembly is made movable to adjust height difference with the main body frame, then the air output direction can be optimized for horizontal blow, but the device complexity increases
Solution Approach 1:
The air outlet assembly is designed to be movable relative to the main body frame, allowing dynamic adjustment of the height difference between them. This enables the air outlet to form at different positions, optimizing the air output direction for horizontal blow during cooling mode. The movable design transforms a static structure into a dynamic one that can adapt to different operational requirements.
2Quantity of substance
If the air outlet dimension between the air outlet assembly and main body frame is increased, then the air output volume attenuates less, but the air supply distance becomes very short
Solution Approach 1:
The patent optimizes the dimension parameters of the air outlet formed between the air outlet assembly and the main body frame. By carefully controlling the height difference and the dimensions of the air outlet opening, the design achieves a balance where the air output volume is maintained while the air supply distance is extended. This involves precise parameter selection for the air outlet geometry.
3Ease of operation
If the air deflector angle is increased to adjust air output direction, then the air can be directed horizontally, but the air output volume is reduced as air blows directly to the wall
Solution Approach 1:
The air deflector is designed with optimized angular parameters to achieve the desired air output direction without excessive deflection. The deflector angle is carefully selected to guide air horizontally along the wall rather than directly into it, maintaining air output volume while achieving the cooling effect. This involves precise control of the deflector's geometric parameters.
4Length of stationary object
If the air deflector downward swing angle is increased to extend air supply distance, then the air can reach farther, but the air supply distance is actually reduced due to poor air output effect
Solution Approach 1:
The air deflector's swing angle parameters are optimized to achieve the maximum air supply distance. The downward swing angle is carefully controlled to allow air to travel farther along the wall while maintaining sufficient air output volume. This involves precise parameter optimization to balance distance and volume requirements.
