Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional devices are used to generate standing waves, then wave generation is achieved, but the water flow becomes turbulent and control precision is poor
Solution Approach 1:
The flow straightener is installed upstream in the evacuation device to preliminarily condition the water flow before it reaches the wave generation zone. This preliminary action of straightening and laminarizing the flow prevents turbulence from developing downstream, thereby achieving both smooth flow and precise wave control simultaneously
Solution Approach 2:
The flow straightener acts as an intermediary component between the water source and the wave generation mechanism. It mediates the flow characteristics by converting turbulent flow into laminar flow, which then enables precise control of the standing wave generation without the harmful effects of turbulence
2Productivity
If energy is increased to generate standing waves, then wave generation is achieved, but energy efficiency decreases due to turbulence and loss
Solution Approach 1:
The invention changes the flow parameters (from turbulent to laminar) through the flow straightener, which reduces energy dissipation. By controlling the flow regime parameter, the system achieves efficient wave generation with minimal energy loss, as laminar flow maintains kinetic energy better than turbulent flow
3Productivity
If flow rate is increased to improve wave generation, then productivity increases, but turbulence increases and safety decreases
Solution Approach 1:
The flow straightener performs preliminary flow conditioning at high flow rates, establishing laminar flow patterns before water enters the wave generation zone. This allows the system to operate at high productivity levels while maintaining safety, as the preliminary straightening prevents dangerous turbulence even at increased flow rates
