Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw and gasket mounting method is used, then reliable connection is achieved, but assembly complexity increases and assembly time extends
Solution Approach 1:
The patent extracts and removes the connecting member (screw and gasket assembly) from the mounting system. Instead of using traditional screws and gaskets, the invention integrates the connection function directly into the blade and mounting plate through inserting portions, eliminating the need for separate connecting components and simplifying the overall structure.
Solution Approach 2:
The patent merges the connection function with the structural components themselves. The inserting portion in the blade and the corresponding receiving structure in the mounting plate are integrated into these components, combining the structural support and connection functions into a unified system without separate fastening elements.
2Reliability
If multiple screws and gaskets are used for mounting, then secure attachment is achieved, but the number of parts increases and cost rises
Solution Approach 1:
The invention extracts and eliminates the need for multiple screws and gaskets by integrating the connection function into the blade and mounting plate structures themselves, reducing the total number of parts while maintaining secure attachment.
Solution Approach 2:
The inserting portion and mounting plate structure serve multiple functions simultaneously: they provide structural support, enable secure attachment, and allow for tool-free assembly. This multi-functionality eliminates the need for separate dedicated fastening components.
3Reliability
If traditional mounting method with connecting members is used, then reliable connection is achieved, but assembly time increases and tool requirements increase
Solution Approach 1:
By removing the connecting member and its associated assembly process, the invention eliminates the time-consuming steps of aligning, inserting, and fastening multiple components, reducing assembly time while maintaining connection reliability through the integrated inserting portion design.
Solution Approach 2:
The inserting portions are pre-formed as integral parts of the blade and mounting plate during manufacturing, eliminating the need for assembly-time fastening operations. The connection is prepared in advance through the molded-in inserting portions, enabling rapid tool-free assembly.
4Reliability
If traditional screw mounting is used, then secure attachment is achieved, but auxiliary tools are required and assembly complexity increases
Solution Approach 1:
The invention extracts and eliminates the need for auxiliary fastening tools by removing the connecting member system. The integrated inserting portion design allows for direct hand assembly without requiring screwdrivers, wrenches, or other specialized tools, greatly simplifying the assembly operation.
Solution Approach 2:
The inserting portion and mounting plate structure are designed to self-align and self-secure during assembly. The elastic snap-fit mechanism automatically provides the necessary connection force and positioning, eliminating the need for external tools or complex assembly procedures.

AI summary
A ceiling fan blade structure and a ceiling fan. The ceiling fan blade structure includes: at least one fan blade provided with a first inserting portion; and a mounting plate provided with a second inserting portion, and being able to be detachably connected with the fan blade through a fit between the first inserting portion and the second inserting portion. The installation of the fan blade is changed, and the connecting members used in the existing mounting method of fan blades are removed. The fan blade is provided with the first inserting portion, the mounting plate is provided with the second inserting portion, and through corresponding insertion between the first inserting portion and the second inserting portion, the fan blade may be mounted to the mounting plate rapidly. Moreover, in a mounting process of the fan blade, a mounting operation can be completed without assistance of auxiliary tools.
