Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airflow-direction adjustment devices in cooling and heating equipment are bulky, complex, and heavy due to the large number of vanes and intricate gear mechanisms, leading to increased weight and assembly issues, which complicates airflow direction adjustment and increases costs.
Innovation Solution
A simplified airflow-direction adjustment device with a pair of vanes supported on a common pivot line, utilizing a reduced number of gear mechanisms that allow for multilateral variation in airflow direction, including a spherical housing and semi-disk shaped vanes, to reduce weight and complexity while maintaining effective airflow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vanes (four or more) are used to effectively adjust airflow direction, then airflow-direction adjustment effectiveness is improved, but device complexity and weight increase
Solution Approach 1:
The housing is divided into a first housing and a second housing that can rotate relative to each other, with each housing containing vanes that can be independently adjusted. This segmentation allows effective airflow direction control through coordinated rotation of the housings and vanes, while avoiding the need for a large number of vanes in a single housing, thus reducing structural complexity.
2Adaptability or versatility
If multiple fins are used to adjust airflow direction, then airflow control capability is improved, but the gear mechanism becomes complicated and device complexity increases
Solution Approach 1:
The first and second housings serve multiple functions: they contain vanes for airflow direction adjustment, act as gear mechanisms through their relative rotation capability, and provide structural support. This multi-functionality eliminates the need for separate complex gear mechanisms, allowing effective airflow control while simplifying the overall structure.
3Adaptability or versatility
If a large number of parts are used to achieve effective airflow-direction adjustment, then airflow adjustment effectiveness is improved, but assembly property deteriorates and manufacturing cost increases
Solution Approach 1:
The vanes are integrated with the housings, and the housings themselves function as the adjustment mechanism through relative rotation. This merging of components reduces the total number of parts that need to be assembled, improving assembly properties while maintaining effective airflow-direction adjustment capability through the coordinated rotation of the integrated structure.

AI summary
An airflow-direction adjustment device includes a housing in which a front end side is set as an air outlet and a back end side is set as an air inlet; a fin turnably supported inside the housing; and a gear mechanism for adjusting a direction of the fin by a rotation of an operating portion. An essential part is formed such that the fin is formed by a pair of vanes disposed on right and left or top and bottom inside the housing, and each vane is turnably supported in a front-and-back direction of the housing respectively as a supporting point on a common pivot line set in a plate width direction.
