Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air registers in vehicles primarily control airflow direction and intensity but fail to provide diffused airflow, which is desirable for gentle air release from vehicle cavities, and may experience pressure build-up issues when closed.
Innovation Solution
An air register design featuring a combination of diffuser discs and a tilt ring that allows for rotation and tilting, enabling the air register to transition from a closed to open configuration, diffusing airflow and incorporating a pressure relief mechanism to prevent pressure build-up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air registers are closed to control airflow direction, then airflow direction control is improved, but pressure build-up occurs in the vehicle cavity
Solution Approach 1:
The air register incorporates a pressure relief mechanism with a specific aperture that remains open even when the main airflow control flaps are closed. This local opening provides a pressure equalization path while the majority of the register maintains its closed position for directional control, thus resolving the contradiction between effective closure and pressure management
Solution Approach 2:
The air register is divided into multiple functional components: main control flaps for directional control and a separate pressure relief aperture. This segmentation allows different parts of the same device to perform different functions simultaneously - the main flaps control airflow direction while the pressure relief aperture prevents pressure build-up
2Ease of operation
If conventional air registers are designed for directional control, then airflow direction is improved, but diffused airflow is not provided
Solution Approach 1:
The air register incorporates multiple movable flaps that can be positioned at different angles independently. This dynamic configuration allows the system to switch between concentrated directional airflow (when flaps are aligned) and diffused airflow patterns (when flaps are angled differently), providing both directional control and diffused airflow capability
Solution Approach 2:
The air register is designed to perform multiple functions: it can provide concentrated directional airflow for targeted climate control, diffused airflow for gentle air release, and pressure relief. The same device structure supports both precise directional control and diffused airflow patterns through adjustable flap configurations

AI summary
An air register can control airflow direction and intensity. The air register includes an attachment mechanism that is configured to attach to a surface. The air register further includes a plurality of diffuser discs attached to the attachment mechanism and configured so that they may be manually moved from a closed configuration to an open configuration. The diffuser discs include a plurality of apertures that allow air to flow therethrough. In the closed configuration, the diffuser discs are arranged to cover the apertures so that air cannot flow therethrough. In the open configuration, the plurality of diffuser discs are spaced apart to allow air to flow through the apertures. Further, the diffuser discs can be tilted to control airflow direction.
