Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the blade seat is designed with a fixed quantity of fan blades for each model, then the manufacturing process is simplified for that specific model, but the adaptability to different user requirements and environments is reduced
Solution Approach 1:
The blade seat is segmented into an upper fixed plate and a lower fixed plate that can be separated and reassembled. The through holes are distributed in multiple rows on each plate, allowing selective assembly of different数量的 fan blades. This segmentation enables both simplified standardized manufacturing of the plates and flexible configuration of the complete fan blade assembly according to different requirements.
Solution Approach 2:
The blade seat transitions from a static, fixed-configuration design to a dynamic, adjustable configuration. By providing multiple rows of through holes and allowing the separation and reassembly of the upper and lower fixed plates, the system enables users to adjust the quantity and arrangement of fan blades based on different environmental conditions and practical needs, while maintaining standardized manufacturing processes.
2Manufacturing precision
If different production lines are required for manufacturing blade seats of different models, then each model can be optimized specifically, but the manufacturing complexity and cost increase
Solution Approach 1:
The upper and lower fixed plates are designed as universal components with standardized through hole patterns that can accommodate different quantities and configurations of fan blades. This universal design allows a single standardized production line to manufacture blade seats for multiple different models and configurations, eliminating the need for separate production lines while maintaining model-specific optimization through selective assembly configurations.
3Device complexity
If the fan blade quantity is fixed in the blade seat design, then the structural design is simplified, but the user cannot adjust according to environment or practical requirements
Solution Approach 1:
The blade seat incorporates multiple rows of through holes arranged in different patterns, enabling dynamic reconfiguration of fan blade quantities and arrangements. Users can selectively assemble different numbers of fan blades by aligning them with corresponding through holes and securing with fastening components, providing operational flexibility while maintaining a relatively simple overall structure.
Solution Approach 2:
Fastening components serve as intermediaries between the upper and lower fixed plates and the fan blades. These components enable easy assembly and disassembly of fan blades by passing through the distributed through holes, allowing users to adjust the fan blade configuration without complex tools or procedures while maintaining structural integrity.

AI summary
A ceiling fan and a fan set are provided. The fan set includes an upper fixed plate, a lower fixed plate, and a plurality of fan blades. The upper fixed plate has a plurality of first through holes that are in a ring-shaped arrangement, and the lower fixed plate has a plurality of second through holes that are in a ring-shaped arrangement. The quantity of the second through holes is equal to the quantity of the first through holes, and the positions of the second through holes respectively correspond to the positions of the first through hole. Each of the fan blades has an assembly portion, a blade portion, and three fasteners. The fasteners pass through the first through holes and the second through holes such that each of the fan blades is fastened between the upper fixed plate and the lower fixed plate.
