Solution Overview

Problem

Conventional air vents with low height and wide width, known as joint vents, face limitations in air deflection due to the placement of slats, which restricts effective air distribution, especially when the slats are short, and the deflection mechanism is often visible, affecting aesthetics and functionality.

Innovation Solution

The air vent design features a rotatably mounted air guide element centrally in the duct, with slats positioned behind the air guide element, allowing for improved air deflection without visible moving parts. The air guide element is designed to be round with no sharp edges, and the slats are pivotally connected via webs and a common axis, enabling greater control over air flow direction and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If slats are positioned upstream in the air duct for air deflection, then air deflection is achieved, but the slats and deflection mechanism become visible above the air outlet opening, affecting aesthetics

Engineering Contradiction:
Improveair deflection capabilityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent inverts the conventional arrangement by positioning the slats downstream behind the air guide element rather than upstream. This reversal allows the air deflection function to be maintained while the slats remain hidden from view above the air outlet opening, resolving the contradiction between functionality and aesthetics

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

Solution Approach 2:

The slats are nested within the air duct behind the air guide element, creating a layered configuration where the air guide element is positioned in front of the slats. This nesting arrangement allows the deflection mechanism to be concealed while still performing its function, addressing both aesthetic and functional requirements

Inventive Principle:
Principle #7Nested doll (Nesting)

2Shape

If joint vents are designed with low height and wide width, then the vent profile is sleek and modern, but air deflection capability is significantly limited

Engineering Contradiction:
Improvelow-profile designVSAvoidair deflection capability
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent transitions from traditional lateral air deflection to vertical air deflection by orienting the slats to deflect air in the vertical direction. This dimensional change allows effective air distribution to be achieved within the constrained low-height profile of joint vents, resolving the contradiction between sleek design and functional capability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent changes the deflection direction parameter from horizontal to vertical, enabling the air vent to achieve effective air distribution capability while maintaining the low-profile joint vent design. This parameter change allows the vent to overcome the limitations imposed by its compact dimensions

Inventive Principle:
Principle #35Parameter changes

3Length of stationary object

If slats are made short to fit low-profile joint vents, then the vent height is reduced, but air deflection effectiveness is significantly reduced

Engineering Contradiction:
Improvevent heightVSAvoidair deflection effectiveness
Core Design Contradiction:
Length of stationary objectVSEase of manufacture

Solution Approach 1:

The patent inverts the conventional horizontal deflection approach and implements vertical deflection using the air guide element and vertically oriented slats. This inversion allows short slats to achieve effective air deflection in the vertical direction, resolving the contradiction between reduced height and maintained deflection effectiveness

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

Solution Approach 2:

The patent changes the deflection orientation from horizontal to vertical, allowing short slats to provide effective air distribution within the low-profile joint vent. This parameter change enables the slats to overcome their length limitation by operating in a different directional plane
