Solution Overview

Problem

Existing devices for generating standing waves struggle to produce a consistent, laminar flow of water with a flat surface, which is essential for creating a stable wave, as they often result in turbulence and inefficiencies in energy usage.

Innovation Solution

A device comprising a ramp and a discharge system with a blade that smooths the water surface, featuring a movable blade with adjustable height and angle to control the flow, combined with a flow straightener using guide plates to reduce turbulence and ensure laminar flow, and a compartment with pumps for efficient water circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If water is directed onto a ramp using conventional discharge devices, then a standing wave can be generated, but the water flow becomes turbulent and the surface becomes uneven

Engineering Contradiction:
Improvewater flow stabilityVSAvoidturbulence
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The discharge device is designed to pre-condition the water flow before it reaches the ramp. The flow straightener elements and blade are positioned upstream to eliminate turbulence and flatten the water surface in advance, ensuring laminar flow conditions when the water contacts the ramp, thus generating stable standing waves without turbulence-induced disturbances

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A blade is introduced as an intermediary element between the discharge opening and the ramp. This blade acts as a flow conditioner that smooths the water surface and directs the flow uniformly onto the ramp, mediating between the discharge mechanism and the wave-generating surface to eliminate turbulence and ensure consistent wave formation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If conventional discharge devices are used to generate standing waves, then wave formation is possible, but energy usage becomes inefficient

Engineering Contradiction:
Improvewave generation efficiencyVSAvoidenergy expenditure
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The discharge device parameters are optimized to match the ramp characteristics. The blade angle, height, and position are adjustable to precisely control the flow parameters (velocity distribution, flow rate, impact angle) so that the water energy is efficiently transferred to wave formation with minimal loss, maximizing wave generation productivity while minimizing energy expenditure

Inventive Principle:
