Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional propeller devices are used for water circulation, then water circulation function is provided, but power requirements are high and operational costs are expensive
Solution Approach 1:
The peller blade incorporates a movable flap structure that can dynamically adjust its position and angle relative to the blade. This dynamic adjustment allows the blade to optimize its hydrodynamic characteristics during operation, enabling efficient water circulation at lower power requirements compared to conventional fixed propeller devices
Solution Approach 2:
The peller blade with flap structure is designed to function effectively as both a propeller (pushing water) and an impeller (creating suction), providing multi-functional capability. This universality allows the device to achieve high productivity in water circulation while reducing power requirements through optimized flow patterns
2Power
If conventional impeller devices are used for water circulation, then water circulation function is provided, but power requirements are high and operational costs are expensive
Solution Approach 1:
The movable flap structure on the peller blade enables dynamic optimization of the impeller function by adjusting the blade angle and shape during rotation, reducing power requirements while maintaining high water circulation efficiency
Solution Approach 2:
The flap structure allows for changes in blade geometry parameters during operation, optimizing the hydrodynamic performance for impeller function and enabling efficient water circulation at reduced power consumption
3Power
If peller device with flap structure is used, then efficiency is increased and power requirements are reduced, but device complexity increases
Solution Approach 1:
The peller blade is segmented into the main blade structure and a separate movable flap component. This segmentation allows the flap to be independently positioned and adjusted, reducing power requirements while keeping the added complexity manageable through modular design
Solution Approach 2:
The flap acts as an intermediary element between the blade and the water, mediating the interaction to optimize hydrodynamic performance. This intermediary structure reduces power requirements while the simplicity of the flap mechanism keeps device complexity relatively low

AI summary
A peller device with a flap is an apparatus used to enhance the capabilities and efficiency of water circulation and aeration systems. The apparatus is configured to act as both a propeller and an impeller as necessary for a particular water circulation requirement. A flap is an addition to the blade tip which propels a fluid by pushing against the fluid, thus enabling the peller to function as a propeller. In addition, the flap facilitates the generation of a sucking force so the peller can also function efficiently as an impeller. The peller assembly can be encased in circular housings having a vertical axis in which the peller assembly is mounted for rotation on the central axis of the housing. The peller assembly is formed with a hub and a plurality of blades symmetrically positioned around the hub. The flap of the apparatus is attached to the base of the peller assembly.
