Blade adapter and ceiling fan including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans require multiple blade types with different angles to accommodate varying air volume and airflow range demands, leading to increased manufacturing costs and inefficiencies due to the need for multiple molding processes.
Innovation Solution
A blade adapter with adjustable blade connection sections that allow for windward and inclination adjustments, enabling the same blades to be used for different airflow configurations by forming inclined portions on the blade connection faces, which can be bent or angled to alter airflow characteristics without the need for multiple blade types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple blade types with different angles are produced to meet varying airflow requirements, then the airflow volume and range requirements are satisfied, but the manufacturing cost increases and production efficiency decreases
Solution Approach 1:
The blade adapter is designed as a universal component that can be installed on standard blades to provide multiple airflow configurations. The adapter includes a support portion and blade connection sections with inclined portions that can be adjusted to different angles, allowing a single blade design to serve multiple airflow requirements (different volumes and ranges) without needing multiple specialized blade types.
Solution Approach 2:
The blade adapter is divided into distinct functional segments: a support portion that attaches to the ceiling fan motor housing, and multiple blade connection sections that connect to the blades. Each blade connection section includes an inclined portion with adjustable angle. This segmentation allows the airflow configuration to be modified by adjusting the blade connection sections while keeping the main blade structure unchanged, reducing manufacturing complexity.
2Adaptability or versatility
If multiple blade types with different angles are produced to meet varying airflow requirements, then the airflow volume and range requirements are satisfied, but the production time increases
Solution Approach 1:
The blade adapter serves as a universal interface that enables a single blade design to achieve multiple airflow configurations through adjustable inclined portions. This eliminates the need for manufacturers to produce multiple specialized blade types, thereby streamlining the production process and improving overall productivity while still meeting diverse airflow requirements.
Solution Approach 2:
The blade connection sections feature adjustable inclined portions that can be positioned at different angles relative to the horizontal plane. This dynamic adjustability allows the same blade-adapter assembly to be configured for different airflow volumes and ranges, replacing the static need for multiple fixed-angle blade types and simplifying production.
3Adaptability or versatility
If the blade connection face includes inclined portions to adjust airflow, then the airflow volume and range can be adjusted, but the structural complexity increases
Solution Approach 1:
The blade adapter structure is segmented into a support portion and multiple independent blade connection sections. Each blade connection section contains an inclined portion with a specific adjustment angle. This segmentation allows the complexity to be distributed and managed in modular units, making the overall structure more manageable despite the added adjustability features.
Solution Approach 2:
The blade connection sections include inclined portions that extend beyond the minimal necessary structure, providing adjustment angles that may exceed what is strictly required for basic functionality. This excessive action ensures comprehensive coverage of different airflow requirements and simplifies the design by providing built-in adjustment ranges rather than requiring multiple separate components.
