Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional wave generation systems are used, then wave energy is distributed into multiple smaller auxiliary waves, but the desired large solitary wave cannot be generated

Engineering Contradiction:
Improvewave shapeVSAvoidwave consistency
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent modifies the geometric parameters of the wave generator foil, specifically using a concave cross-sectional shape with optimized curvature radii (R1=0.5m, R2=2m) and thickness distribution. This parameter optimization transforms the wave generation pattern from distributed Kelvin wakes to a concentrated solitary wave, achieving both desired shape and consistency

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The wave generator employs dynamic control of the foil's position, angle of attack, and submersion depth. By dynamically adjusting these parameters during operation, the system maintains optimal wave generation conditions and produces consistent solitary waves despite varying operational requirements

Inventive Principle:
Principle #15Dynamics

2Productivity

If artificial wave generators are used in constrained pools, then wave generation is achieved, but significant chop, reflective waves, and seiche are produced

Engineering Contradiction:
Improvewave generation capabilityVSAvoidreflective waves and chop
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the potentially harmful reflected waves into beneficial elements by designing the pool geometry and wave timing to allow constructive interference. The solitary wave's non-breaking nature and the pool's specific dimensions transform reflections into additional wave energy rather than disruptive chop

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The convex parabolic beach region acts as an intermediary element that absorbs and dissipates reflected wave energy. This geometric feature serves as a buffer between the wave generation zone and the pool boundaries, converting harmful reflections into gentle wash that enhances the surfing experience

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If non-bi-directional wave generators are used, then wave generation in one direction is achieved, but the system lacks versatility for different surfing conditions

Engineering Contradiction:
Improvewave generation simplicityVSAvoidbi-directional capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The wave generator foil employs asymmetric geometry with different concave curvatures on each face (R1=0.5m on one side, R2=2m on the other). This asymmetric design enables the single foil to generate optimal solitary waves in both directions when oriented differently, providing bi-directional capability without requiring multiple generators

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The single wave generator foil is designed to perform multiple functions: generating solitary waves in both directions, controlling wave height through angle adjustment, and adapting to different pool configurations. This multi-functional design eliminates the need for separate generators for each direction while maintaining operational simplicity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A wave pool and wave generating mechanism are disclosed. The wave pool includes a bathymetry that includes a dynamically shapeable reef along a length or circumference of a channel that defines the wave pool. The wave generating mechanism includes a foil that has a shape for bi-directionality based on an adjustment of a yaw angle of the foil. The foil can be further controlled to increase or decrease certain surface areas or other angles of interacting with water in the wave pool.
