Solution Overview

Problem

Existing air conditioner deflector movement assemblies are complex and occupy internal space, making them inefficient in adjusting air output angles and interfering with the machine body during operation.

Innovation Solution

A movement assembly comprising a push plate, driving disc, and rotary assembly that allows the air deflector to extend and retract smoothly, utilizing a rotary movement of the driving disc to save internal space and ensure stable transmission, featuring a guide groove with an arc shape and elastic anti-skid layer for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a complex mechanism is used to push out the air deflector, then the air deflector can be pushed out smoothly, but the structure becomes complex and occupies internal space of the machine body

Engineering Contradiction:
Improvesmooth pushing out of air deflectorVSAvoidcomplexity of pushing mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the air deflector from the machine body by using a simple push plate mechanism that pushes the air deflector outward during overturning movement. This separates the air deflector's movement function from the main machine body structure, avoiding the need for complex internal pushing mechanisms while still achieving smooth extraction and positioning of the air deflector.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If a complex mechanism is used to push out the air deflector, then the air deflector can be pushed out smoothly, but internal space of the machine body is occupied

Engineering Contradiction:
Improvesmooth pushing out of air deflectorVSAvoidinternal space of machine body
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The air deflector is extracted from the machine body using a minimalistic push plate structure that occupies negligible internal space. The push plate simply pushes the air deflector outward during operation, allowing the air deflector to be positioned outside the machine body during overturning movement without consuming valuable internal space.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of pushing the air deflector out from inside the machine body using a complex mechanism, the patent inverts the approach by allowing the air deflector to be pushed outward by the overturning movement itself, with the push plate serving only as a simple interface element rather than a complex actuating mechanism.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If the air deflector performs large-angle overturning movement, then air output angle can be adjusted, but the air deflector interferes with the machine body during overturning movement

Engineering Contradiction:
Improveair output angle adjustmentVSAvoidinterference with machine body
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by pushing the air deflector outward from the machine body before the large-angle overturning movement begins. This preliminary extraction ensures that during the subsequent overturning movement, the air deflector operates in clear space outside the machine body, completely avoiding interference with the machine body structure while maintaining full adjustability of the air output angle.

Inventive Principle:
Principle #10Preliminary action
