Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional transverse air deflectors and longitudinal air blades are used to guide air flow, then air flow direction can be controlled, but the structure becomes complicated and creates dead corners of air supply

Engineering Contradiction:
Improveair flow direction controlVSAvoidair outlet structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The air outlet plate is divided into a fixed portion and a rotatable portion, allowing independent control of air flow direction without requiring multiple complex deflection components. The rotatable portion can be rotated to different angles to guide air flow in different directions, simplifying the overall structure while maintaining controllability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The air outlet plate transitions from a static structure to a dynamic one with rotatable capability. The rotatable portion can be adjusted to different positions and angles, enabling flexible air flow direction control without requiring multiple fixed deflection components, thus reducing structural complexity.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If traditional air outlet structures are used, then assembly is straightforward, but the form is monotonic and air supply control is difficult

Engineering Contradiction:
Improveassembly simplicityVSAvoidair supply control flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The air outlet plate is designed with rotatable capability, transforming it from a static to a dynamic component. This allows the air outlet to adapt to different air supply requirements by adjusting the rotation angle, providing versatility in air flow direction and volume control while maintaining a relatively simple assembly process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotatable air outlet plate serves multiple functions: it controls air flow direction, adjusts air supply volume, and can be positioned at different angles to eliminate dead corners. This single component performs multiple functions that would otherwise require several separate components, enhancing adaptability without significantly complicating assembly.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If fixed air outlet plates are used, then the structure is simple, but the air supply volume and blowing air down effect are difficult to control

Engineering Contradiction:
Improveoutlet structureVSAvoidair supply control
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The air outlet plate is designed with rotatable capability, transforming it from a static to a dynamic component. This allows the air outlet to adapt to different air supply requirements by adjusting the rotation angle, providing versatility in air flow direction and volume control while maintaining a relatively simple assembly process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By changing the rotation angle parameter of the air outlet plate, the air flow direction and volume can be controlled. The rotatable portion can be adjusted to different angles, which directly changes the parameters of air supply, allowing flexible control over air flow characteristics without complex mechanisms.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present application relates to an air outlet mechanism and an air treatment device. The air treatment device is provided with a vertical air duct. A first upper end surface of the vertical air duct is obliquely arranged. The air outlet mechanism includes a first air outlet plate and a second air outlet plate. The first air outlet plate surrounds a higher side of the first upper end surface and is rotatably connected to the air treatment device. The second air outlet plate surrounds other parts of the first upper end surface and is connected to the air treatment device. The first air outlet plate includes a straight plate rotatably connected to the air treatment device and an arc-shaped plate connected to the straight plate. An end of the second air outlet plate away from the first upper end surface is inclined toward an outer side of the air duct. An air outlet is formed between the first air outlet plate and the second air outlet plate. The air outlet is capable of being adjusted by rotating the first air outlet plate. The rotation of the first air outlet plate can adjust the shape, size and air flow direction of the air outlet, increasing the flexibility and controllability of the air output, which is easy to control and achieve satisfactory air supply volume and air blow-down effect, and eliminates the dead corners of the air supply. The air outlet mechanism has high integrity, and can be conveniently produced and easily assembled.
