Air Register Lid Assembly for Hidden Vent Structure and Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioning registers have a design flaw where internal structures, such as vertical blades, can be seen through gaps between horizontal blades, impairing the aesthetic and functional properties.
Innovation Solution
The air-conditioning register incorporates a cylindrical retainer with a lid assembly that covers the opening portion, featuring a rotatable lid assembly with fins and a flow dividing portion to adjust airflow direction and balance flow rates between two air outlets, ensuring the internal structure is not visible externally and enhancing design properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If horizontal blades are spaced apart to allow airflow adjustment, then airflow control is improved, but internal structures become visible through gaps, impairing design properties
Solution Approach 1:
A lid assembly is introduced as an intermediary component between the horizontal blades and the external environment. The lid assembly includes a lid body that covers the gaps between horizontal blades, preventing visibility of internal structures while maintaining airflow control functionality through its rotation capability.
Solution Approach 2:
The lid assembly is designed to be rotatable around the airflow adjustment axis, allowing it to dynamically adjust between covering and exposing the horizontal blades. This dynamic configuration enables the system to switch between aesthetic mode (lid covering) and airflow adjustment mode (lid rotated away).
2Shape
If a lid assembly is added to cover the opening portion, then design aesthetics are improved by hiding internal structures, but device complexity increases
Solution Approach 1:
The lid assembly is merged with the airflow adjustment mechanism by positioning its rotation axis coincident with the airflow adjustment axis. This allows a single rotational movement to simultaneously control both the lid position and the horizontal blade position, reducing the need for separate control mechanisms.
Solution Approach 2:
The lid assembly serves multiple functions: it acts as a aesthetic cover to hide internal structures, functions as an airflow control element through its rotation, and works in conjunction with the horizontal blades to regulate air distribution. This multi-functionality reduces the need for additional separate components.

AI summary
An air-conditioning register includes: a retainer including a retainer inner wall and a retainer opening portion, and having a cylindrical shape, the retainer inner wall defining a retainer ventilation passage, the retainer opening portion being provided at a downstream end of the retainer ventilation passage; and a lid assembly provided in the retainer, and having an exposed surface and a retainer facing surface, the exposed surface being exposed from the retainer opening portion, the retainer facing surface facing the retainer opening portion and defining an air outlet between the retainer facing surface and the retainer opening portion.
