Solution Overview

Problem

Conventional air vents have limitations in lateral air deflection, require significant installation space, and are complex and prone to faults due to numerous components and complex kinematics, with limited orthogonal air deflection capabilities.

Innovation Solution

An air vent design featuring shells directly connected to the air guide element, allowing pivoting to control air flow into partial ducts, and slats mounted on the air guide element for improved lateral deflection, with a simplified structure and reduced component count, utilizing a cylindrical housing and handle for intuitive operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If louvers are positioned in front of the airflow to achieve lateral air deflection, then lateral air deflection is improved, but installation space is increased

Engineering Contradiction:
Improvelateral air deflectionVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent combines the air guide element and louvers into a single integrated rotatable component. The louvers are mounted directly on the air guide element, so that one rotation movement simultaneously controls both the air guide element position and the louver angle, eliminating the need for separate louver mechanisms and reducing installation space.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rotatable air guide element serves multiple functions: it guides air flow direction, controls the angle of the louvers, and regulates air volume through its rotation position. This multi-functionality replaces what would traditionally require separate components for each function, reducing overall device complexity and space requirements.

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

2Ease of operation

If a closing flap is added as a throttling device to control air volume, then air volume regulation is improved, but installation space is increased

Engineering Contradiction:
Improveair volume regulationVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent integrates the throttling function into the rotatable air guide element itself. By rotating the air guide element to different positions, the effective opening area is automatically regulated, combining the air guide and throttling functions into a single component rather than requiring a separate closing flap mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The air guide element transitions from a static component to a dynamic rotatable component that can adjust its position and the louver angle simultaneously. This dynamic adjustment mechanism provides both air direction control and volume regulation through a single degree of freedom, eliminating the need for additional static throttling components.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If multiple components with complex kinematics are used to achieve air deflection, then air deflection control is improved, but device complexity is increased

Engineering Contradiction:
Improveair deflection controlVSAvoidcomponent count and kinematics
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple air deflection control functions into a single rotatable air guide element with integrated louvers. Instead of having separate mechanisms for guiding air and adjusting louver angles, both functions are achieved through one rotation movement, dramatically reducing component count and kinematic complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The air guide element is segmented into functional zones (front surface for air guidance, louver mounting surface for lateral deflection) that work together through a single rotational degree of freedom. This segmentation allows complex air flow control to be achieved through simple rotational motion rather than multiple independent mechanisms.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If the air guide element has minimum height to accommodate lever mechanism, then air deflection capability is improved, but housing height is increased

Engineering Contradiction:
Improveair deflection capabilityVSAvoidhousing height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The patent replaces the lever mechanism with a direct rotation mounting. The air guide element is rotatably mounted on the housing wall without requiring a lever arm or pivot mechanism that would extend into the housing. This substitution eliminates the need for minimum height clearance and allows the housing to be more compact.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
