Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional fan blade mounting and removal methods are used, then secure fixation of fan blades is achieved, but the disassembly process involves numerous parts and complicated steps leading to high maintenance costs
Solution Approach 1:
The locking mechanism is segmented into independent locking sliders, each controlling a specific fan blade. Each locking slider can be independently adjusted via its own adjusting component, allowing individual blade maintenance without affecting other blades. This segmentation simplifies the overall disassembly process by breaking down the complex multi-part traditional locking system into modular, independently operable units.
Solution Approach 2:
The locking slider and adjusting component assembly is extracted as a separate, pre-assembled unit from the traditional integrated locking mechanism. This extracted module can be independently manipulated to remove or mount fan blades, eliminating the need to disassemble the entire fan structure. The elastic component is also extracted as a separate element that provides automatic locking force without requiring additional fastening parts.
2Reliability
If traditional fan blade fixation methods are used, then reliable locking is achieved, but numerous parts and complicated disassembly steps increase maintenance costs
Solution Approach 1:
The elastic component is configured to automatically exert locking force on the fan blade mounting end when the locking slider is positioned in the locked state. This self-service mechanism eliminates the need for additional fasteners, clips, or complex locking procedures - the system automatically maintains reliable fixation through the elastic force, simplifying both installation and maintenance operations while ensuring consistent locking reliability.
Solution Approach 2:
The locking force parameter is dynamically controlled by the adjusting component, which modifies the position of the locking slider along the movable cavity. By changing the positional parameter of the locking slider, the system adjusts the degree of engagement with the fan blade mounting end, providing reliable locking when needed while allowing easy release when the adjusting component is moved to the unlocked position.
3Loss of time
If quick mounting and removal of fan blades is implemented, then maintenance time is reduced, but the mounting mechanism requires additional components like locking sliders and adjusting components
Solution Approach 1:
The locking slider is designed to be movable within the movable cavity rather than fixed, allowing it to dynamically transition between locked and unlocked positions. The adjusting component enables this dynamic repositioning through simple rotational motion that translates to linear movement of the locking slider. This dynamic design allows quick state changes between locked and unlocked, reducing mounting/removal time while keeping the mechanism relatively simple through the use of basic mechanical motion conversion.
Solution Approach 2:
The adjustable component serves multiple functions: it acts as a actuator to move the locking slider, a position controller to set the locking state, and a release mechanism to unlock the fan blade. By consolidating these multiple functions into a single component, the system achieves quick mounting and removal capabilities without requiring separate components for each function, thereby minimizing the increase in overall mechanism complexity.

AI summary
A fan device is provided, including a fan assembly. The fan assembly includes fan blades, locking sliders, adjusting components, and elastic components. A peripheral side wall of the rotating module defines movable cavities, and each of the locking sliders is slidable and disposed in a corresponding one of the movable cavities. Each of the elastic components is disposed in a corresponding one of the movable cavities, and two ends of each of the elastic components are respectively abut against a top surface of the corresponding one of the movable cavities and a corresponding one of the locking sliders. In a normal state, each of elastic components drive the corresponding one of locking sliders to move toward a bottom surface of the corresponding one of the movable cavities.
