Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional fluid deflection devices are used, then fluid deflection function is provided, but flow losses are high
Solution Approach 1:
The fluid deflection device is segmented into multiple identical fluid distribution elements arranged side by side. Each element handles a portion of the fluid flow independently, reducing turbulence and flow losses while maintaining overall device functionality. This modular segmentation allows optimized flow paths in each element.
Solution Approach 2:
The device employs curved flow guide walls and circular-cylindrical wall configurations instead of sharp angular transitions. These curved surfaces guide fluid flow smoothly, reducing flow separation and turbulence, thereby minimizing flow losses while maintaining structural integrity.
2Ease of manufacture
If conventional fluid deflection devices are used, then fluid deflection function is provided, but manufacturing cost is high
Solution Approach 1:
The device is divided into identical modular fluid distribution elements that can be manufactured separately and assembled. This segmentation enables standardized production processes, reducing manufacturing complexity and cost while allowing parallel production of multiple elements.
Solution Approach 2:
Each fluid distribution element is designed as a universal module that performs the complete fluid deflection function. These identical elements can be replicated and arranged in various configurations to meet different flow requirements, reducing design and manufacturing costs through standardization.
3Volume of moving object
If compact design is implemented, then space efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
By segmenting the device into identical modular elements, each element can be manufactured to standard dimensions with conventional precision. The modular nature allows for easier quality control and assembly, reducing the impact of dimensional accuracy requirements compared to a monolithic compact design.
Solution Approach 2:
Multiple fluid distribution elements are merged side by side to form the complete device, achieving compact overall volume while each individual element maintains manufacturable dimensions. This combining approach allows the compact form factor without excessively tight tolerances on individual components.
