Magnetic Air Vent Damper for Tool-Free Airflow Positioning

Solution Overview

Problem

Current automotive vehicles lack an aftermarket air vent damper apparatus that allows passengers to selectively control airflow into the passenger compartment, leading to discomfort due to inability to tailor air flow to personal preferences.

Innovation Solution

An air vent damper apparatus with retention devices and a pivotally coupled damper, featuring magnetically attracted catch members for manual positioning and installation/removal without tools, allowing passengers to control airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an air vent damper apparatus is not provided in vehicles produced by the original vehicle manufacturer, then vehicle occupants cannot control airflow into the passenger compartment, but adding such a device increases device complexity

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The air vent damper apparatus is designed as a separate, modular unit that can be independently installed in the air vent without modifying the vehicle's original air conditioning system. This segmentation allows the control function to be added without increasing overall system complexity, as the damper operates as a standalone component with its own retention devices and pivot mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The damper apparatus includes manual operation features that allow users to directly control the damper position without requiring electronic controls or complex actuation systems. The manual crank or direct manipulation interface enables self-service operation, simplifying the control mechanism while maintaining ease of use for occupants.

Inventive Principle:
Principle #25Self-service

2Reliability

If the damper is made secure and reliable for airflow control, then the retention mechanism becomes more complex, but if it is too simple, the damper may not stay in position

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The retention devices incorporate spring-loaded or elastic elements that provide more than sufficient retention force to hold the damper in position against airflow pressures. This excessive action ensures reliable positioning without requiring complex multi-stage retention mechanisms, as the simple spring-loaded design naturally provides the necessary holding force throughout the damper's range of motion.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If the air vent damper apparatus is designed for easy installation and removal without tools, then the retention mechanism must be simple, but this may reduce installation security

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The retention devices replace traditional mechanical fastening systems (screws, clips, or adhesives requiring tools) with a friction-based or elastic retention mechanism that allows tool-free installation. The spring-loaded or elastic retention elements provide sufficient holding force to securely retain the damper in the air vent without requiring threaded fasteners or complex mechanical interlocks, thus maintaining installation security while enabling easy tool-free mounting and removal.

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

AI summary

An air vent damper apparatus including first and second retention devices each having a respective body portion. At least one of the retention devices includes at least a first catch member, and at least one of the retention devices includes a second catch member. The first and second catch members define differing damper positions. The apparatus also includes a damper having opposed first and second edges, wherein the damper is pivotally coupled between the first and second retention devices. Each of the first and second edges has a respective third catch member that is magnetically attracted to the first and second catch members the first and second retention devices, such that the damper can be selectively configured in an first position by aligning the third catch member with the first catch member and in a second position by aligning the third catch member with the second catch member.
