Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans are time-consuming to assemble, have unstable assembly quality, and a higher axial height, which increases user oppression and costs.
Innovation Solution
Incorporating an intermediate transition member with heat dissipating holes and radially extending coupling portions that securely connect blades, reducing the fan's thickness and axial height while improving assembly efficiency and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (hub, positioning member, blade) are used to assemble the ceiling fan, then the assembly process becomes more complex and time-consuming, but the structural stability is improved
Solution Approach 1:
The patent integrates the hub, positioning member, and blade into a single integrated component structure. The blade is directly formed as an extension of the hub body, eliminating the need for separate positioning members and multiple assembly steps. This merging of components reduces assembly time while maintaining structural integrity through the unified design.
2Adaptability or versatility
If multiple separate components with certain thickness are used, then the assembly flexibility is improved, but the axial height of the ceiling fan increases
Solution Approach 1:
The patent employs a nested structure where the blade is integrated within the hub's radial extension, and the motor is positioned within the blade assembly. This nesting arrangement allows multiple functional components to occupy overlapping spatial volumes, significantly reducing the overall axial height while preserving assembly flexibility through modular integration.
3Strength
If the ceiling fan components are designed with sufficient thickness for structural integrity, then the strength is improved, but the user experience deteriorates due to increased height and oppression
Solution Approach 1:
The patent transitions from a conventional axial stacking arrangement to a radial expansion design. The blade extends radially from the hub rather than stacking axially, and the motor is positioned centrally within this radial structure. This dimensional change allows the fan to achieve sufficient structural strength through radial distribution while minimizing axial height, thereby improving user comfort.
4Productivity
If conventional assembly methods with multiple separate parts are used, then the manufacturing precision requirements are reduced, but the productivity decreases
Solution Approach 1:
The patent incorporates preliminary integration actions during the manufacturing process, where the blade is pre-formed as an integral part of the hub structure. This preliminary integration eliminates the need for separate positioning members and reduces the number of assembly operations required, thereby improving productivity while maintaining manufacturing precision through streamlined production processes.
