Solution Overview

Problem

Existing vehicle ventilation systems fail to effectively mitigate hot air and prevent intrusion of rain or moisture while providing efficient ventilation.

Innovation Solution

An air vent with a passive ventilation feature and a forced air ventilation system, including a ventilation fan, an air exhaust outlet with a displaceable closure, and a controller connected to a temperature sensor and timer, integrated into a vehicle window frame, which also includes a non-collinear and non-planar air pathway to prevent rain intrusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a ventilation system is provided to remove hot air from the vehicle interior, then ventilation efficiency is improved, but the system becomes vulnerable to rain and moisture intrusion

Engineering Contradiction:
Improveventilation efficiencyVSAvoidrain and moisture intrusion
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The closure member is designed to be displaceable between open and closed positions, allowing the system to dynamically adapt to different environmental conditions. The closure can be opened to enable hot air removal and closed to prevent rain and moisture intrusion, providing dynamic protection while maintaining ventilation functionality.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the air pathway is made linear and planar for simplicity, then manufacturing is easier, but rain intrusion risk increases

Engineering Contradiction:
Improveair pathway fabricationVSAvoidrain intrusion
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The air pathway is configured to be non-collinear and non-planar, introducing dimensional complexity to the path geometry. This three-dimensional routing allows the air pathway to deflect rain and moisture while still providing effective ventilation, solving the rain intrusion problem without requiring additional protective components.

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

3Productivity

If the exhaust outlet remains open for continuous ventilation, then air circulation is improved, but protection from intrusion is reduced

Engineering Contradiction:
Improveair circulationVSAvoidprotection from intrusion
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The closure member provides dynamic control over the exhaust outlet, allowing it to transition between open and closed states. This enables the system to optimize air circulation when conditions are favorable and provide protection when rain or moisture is present, achieving both ventilation efficiency and reliability under different conditions.

Inventive Principle:
Principle #15Dynamics

AI summary

An air vent is mounted in a vehicle window frame. The air vent includes a one-piece body having an interior face and an exterior face. A passive ventilation feature includes an air pathway that extends between a first opening in the interior face to a second opening in the exterior face. A forced air ventilation feature is carried by the body. The forced air ventilation feature includes a ventilation fan, an exhaust outlet and a closure for the exhaust outlet that is displaceable between open and closed positions.
