Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If coordination of sun wheel and planet wheel is adopted for synchronous driving the fan blades, then the fan blades can move synchronously, but the structure of the hidden fan becomes relatively complicated and a large number of parts are used
Solution Approach 1:
The patent extracts and eliminates the complex sun wheel and planet wheel coordination mechanism from the hidden fan structure. Instead, it uses a simplified turntable with radially arranged fan blades that can be directly driven by a motor, removing unnecessary intermediate transmission components while maintaining synchronous movement capability through direct radial arrangement.
Solution Approach 2:
The patent merges the functions of multiple separate components into a more integrated structure. The turntable directly integrates the mounting structure for fan blades, and the motor directly drives the turntable, combining what were previously separate transmission stages into a unified direct-drive system that reduces overall structural complexity.
2Stability of the object's composition
If a large number of parts are used in the hidden fan, then the fan blades can be driven synchronously, but the load on the turntable increases resulting in decrease of energy efficiency
Solution Approach 1:
The patent removes intermediate transmission components (sun wheel, planet wheel) that created additional load on the turntable. The direct radial arrangement of fan blades on the turntable eliminates these intermediate stages, reducing the total load and improving energy efficiency while maintaining synchronous movement through the simplified direct-drive architecture.
3Stability of the object's composition
If a large number of parts are used in the hidden fan, then the fan blades can be driven synchronously, but the overall cost is increased
Solution Approach 1:
The patent extracts and eliminates multiple intermediate transmission parts (sun wheel, planet wheel, associated bearings and mounting structures) from the design. This reduction in part count directly lowers manufacturing costs, material requirements, and assembly complexity while the simplified radial arrangement maintains the essential synchronous movement function with fewer components.
Solution Approach 2:
The patent merges multiple functions into fewer components. The turntable serves as both the mounting structure and the driven element, eliminating separate transmission stages. This consolidation reduces the total number of parts that need to be manufactured, inventoried, and assembled, thereby reducing overall manufacturing cost.
4Stability of the object's composition
If a large number of parts are used in the hidden fan, then the fan blades can be driven synchronously, but the hidden fan is not easy to assemble and the assembling precision may be poor
Solution Approach 1:
The patent removes the complex multi-stage transmission mechanism (sun wheel, planet wheel assembly) that required precise alignment and multiple assembly steps. The simplified radial arrangement of fan blades on the turntable allows for more straightforward assembly with fewer adjustment requirements, improving both ease of assembly and assembly precision.
