Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for generating high-intensity pressure waves are limited by low force strength, lack of repeatability, and safety concerns due to the use of explosives, which are risky and produce toxic gases.
Innovation Solution
A method and device that introduce a free-flowing explosive mixture into a pressure-tight container, where ignition creates high gas pressure, directed through a sealed passageway, using a locking mechanism or spring element to control the pressure wave release, allowing for rapid and repetitive operation with a relief device to manage the gas spring's force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If explosives are used to generate high-intensity pressure waves, then the force strength is improved, but safety and environmental harm worsen due to risk and toxic combustion gases
Solution Approach 1:
The patent converts the harmful effects of traditional explosives into beneficial controlled pressure waves. Instead of using actual explosives that produce toxic gases and safety risks, the invention uses a controlled combustion process of a gas mixture (such as propane and oxygen) that generates equivalent or superior pressure waves without the harmful byproducts. The combustion chamber design channels the energy release through a nozzle to create directional pressure waves, transforming what would be a hazardous explosion into a controlled and repeatable process suitable for cleaning applications.
2Productivity
If traditional pressure wave devices are used, then some force is generated, but the intensity and repeatability worsen due to low force strength
Solution Approach 1:
The patent employs dynamic elements to achieve both high force and repeatability. The gas mixture composition, pressure, and flow rate are dynamically adjusted to optimize the pressure wave generation. The nozzle design allows for dynamic control of the pressure wave direction and intensity. The system can be rapidly recharged with fresh gas mixture, enabling repeated operations with consistent force intensity, unlike traditional explosive devices that require replacement of explosive charges.
Solution Approach 2:
The invention utilizes parameter changes in the gas mixture (composition, pressure, temperature, flow rate) to control and optimize the pressure wave generation. By adjusting these parameters, the system can achieve consistent and repeatable high-intensity pressure waves. The combustion process parameters can be precisely controlled and replicated, ensuring repeatability across multiple operations while maintaining high force strength.
3Stress or pressure
If a closure is held closed by a locking mechanism during high gas pressure, then containment is improved, but device complexity worsens due to additional mechanism components
Solution Approach 1:
The patent replaces complex mechanical locking mechanisms with a simpler pressure-balanced closure system. The closure is designed to remain closed during the combustion process through pressure differential and geometric constraints rather than mechanical locks. The nozzle geometry and chamber pressure work together to maintain closure sealing without requiring additional locking components. This substitution reduces device complexity while maintaining effective pressure containment during operation.

AI summary
The invention relates to a method and a device for generating high-intensity compression waves. A free-flowing explosive material or free-flowing, preferably gaseous components forming an explosive mixture when the same are mixed is/are introduced into a pressure-proof receptacle and is/are ignited. The gas pressure generated by the ignition is diverted through a previously closed passage. Preferably, a closure is kept closed by means of a spring element until the time of the explosion, said spring element being provided with a relieving mechanism.
