Solution Overview

Problem

Existing artificial wave installations for surfing face inefficiencies in capacity utilization and longevity, along with disturbances to the aquatic environment and potential backwash issues, which affect wave frequency and mechanical stress on the support structure.

Innovation Solution

The proposed installation features a support with a top surface including an edge area, wave riding area, and crest area, with an aquatic environment divided into external and internal regions, utilizing a fluid communication system to direct water from the wave's end course into a collection volume, minimizing backwash and sediment disturbance, and incorporating a floating platform or substrate with a spur to manage water currents and wave generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If water is allowed to flow back through the internal aquatic region after wave generation, then the wave path is complete, but backwash disturbs the internal aquatic region and upper external aquatic region causing long delays between waves

Engineering Contradiction:
Improvewave frequencyVSAvoiddelay between waves
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The fluidic communication system redirects water flow from the traditional horizontal backwash path through the internal aquatic region to a vertical evacuation path through openings in the support structure. This dimensional change allows water to exit the wave path area without disturbing the internal and upper external aquatic regions, enabling rapid wave succession.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The harmful backwash flow is extracted from the internal aquatic region by providing a separate evacuation path through the support structure. The water is removed from the problematic area and discharged into the deep external aquatic region, preventing disturbance and allowing continuous wave generation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the support structure is exposed to strong wave forces, then wave generation is effective, but mechanical stress on the support increases reducing longevity

Engineering Contradiction:
Improvewave generation effectivenessVSAvoidsupport structure longevity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The wave forces that would normally create harmful backwash and stress on the support structure are converted into beneficial kinetic energy that drives the water through the fluidic communication system. The water flow generated by wave action is harnessed to evacuate itself from the system, reducing overall mechanical stress on the support while maintaining effective wave generation.

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

3Productivity

If water flows back through the internal aquatic region, then the wave cycle is complete, but sediment is disturbed and the aquatic environment is degraded

Engineering Contradiction:
Improvewave cycle efficiencyVSAvoidsediment disturbance
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The support structure acts as an intermediary element that provides a separate evacuation path for water. Instead of water directly flowing back through the internal aquatic region and disturbing sediment, it is routed through openings in the support structure and discharged into the deep external aquatic region, protecting the aquatic environment from degradation.

Inventive Principle:
Principle #24Intermediary (Mediator)
