Submerged Chamber Wave Generator for Circular Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wave generation systems for pools create turbulent waves that require long wave pools to form and primarily produce supra-water level waves, which are not similar to natural deep water waves, as they generate the wave peak first rather than the trough.
Innovation Solution
A wave generating apparatus that creates a wave trough by rapidly venting gas from a submerged chamber, causing water to flow rearward and reflect off a back wall, producing a wave with circular motion similar to natural deep water waves, with optional augmentation using pressurized air or vacuum to enhance wave height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If water pumping or rapid air pumping machines are used to push water to create waves, then wave generation speed is improved, but the wave quality becomes turbulent and requires long wave pools to form into organized circular motion waves
Solution Approach 1:
Instead of pushing water forward to create the wave peak first (conventional method), the invention pulls water backward to create the wave trough first. This inversion of the wave generation sequence allows the water to naturally flow forward and form organized circular motion waves, resolving the turbulence problem while maintaining rapid wave generation.
Solution Approach 2:
The invention introduces an intermediate mechanism (the chamber that can be rapidly filled with and emptied of water) between the pumping system and the wave pool. This intermediary allows the pumping action to be decoupled from the wave creation, enabling rapid water movement without directly creating turbulent waves in the pool.
2Stress or pressure
If elevated water column is created with vacuum and then released, then wave height is improved, but the wave becomes primarily supra-water level rather than deep water wave with circular motion
Solution Approach 1:
The invention inverts the conventional wave generation approach by creating the wave trough first through rapid water removal, rather than creating the wave peak first through water elevation. This inversion enables the formation of deep water waves with circular motion, as the water naturally flows forward to create the peak after the trough is established.
3Speed
If pressurized air is released rapidly into the generator chamber, then wave generation speed is improved, but the wave created is primarily supra-water level rather than natural deep water wave
Solution Approach 1:
The invention applies pressurized air to rapidly remove water from the chamber (creating the trough), rather than using it to push water forward (creating the peak). This inverted use of pressurized air enables rapid wave generation while simultaneously creating the proper deep water wave structure with circular motion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus generates waves with a natural, circular motion where the trough leads the peak, resembling deep water waves, and can be enhanced to produce larger waves by timed air introduction and vacuum application, resulting in a more realistic wave experience.
Implementation Method 1
a chamber associated with the pool which is at least partially submerged beneath a water level in the pool and which displaces water in the pool when partially or completely filled with gas
Implementation Method 2
Gravity changes the water particle motion from downwards to rearwards, which induces water to flow towards the back wall in a rearward surge
Implementation Method 3
The back wall is positioned and shaped so as to produce the reflected wave
Implementation Method 4
rapidly introducing pressurized air through the air inlet valve timed to increase the height of the wave as it reflects off the back wall
Implementation Method 5
a valve communicating with a vacuum source may be opened in order to apply vacuum to the chamber and increase the rate of exhaust of a gas such as air from the chamber

AI summary
A wave generating apparatus and method in which a chamber is at least partially submerged beneath a body of water in a pool and is connected to a gas supply for at least partially filling the chamber with gas, displacing water in the vicinity of the chamber. A vent valve is arranged to vent gas rapidly from the chamber so that the water level in the vicinity of the chamber falls, forming a wave trough. A wave reflecting wall is positioned in the pool adjacent the chamber and in the vicinity of the wave trough formation so as to reflect the wave away from the chamber and across the body of water. The chamber may have a flexible wall for displacing water or may be a rigid chamber communicating with the water through a submerged passageway. This apparatus forms a wave trough followed by a wave peak which travels across the pool.
