Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively couple an overpressure wave to a target media, such as the ground, with precision and control, leading to inefficiencies in generating conducted acoustic waves for geophysical exploration and seismic applications.
Innovation Solution
A system comprising a detonator, coupling chamber, and interface, where the overpressure wave generated by the detonator is contained within the coupling chamber and converted into a unidirectional force through a piston or flexible membrane, applied directly to the target media, utilizing a vehicle for stabilizing and maneuvering the overpressure wave generator to constrain movement and optimize energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems are used to generate overpressure waves, then the system structure is simple, but the coupling precision and control of overpressure waves to target media is poor
Solution Approach 1:
The system is divided into distinct functional modules: overpressure wave generator, coupling chamber, interface component, and vehicle platform. Each module performs a specific function, allowing for precise control of the overpressure wave generation and coupling process while maintaining manageable system complexity through modular design
Solution Approach 2:
A coupling chamber serves as an intermediary component between the overpressure wave source and the target media. This coupling chamber contains the overpressure wave and provides a controlled interface for energy transfer to the ground, improving coupling precision through optimized energy transmission
2Productivity
If overpressure waves are generated without containment, then the system operation is simple, but the amplitude control and energy transfer efficiency are poor
Solution Approach 1:
The coupling chamber is pre-configured with specific geometric parameters and material properties before overpressure wave generation. This preliminary preparation ensures optimal energy containment and transfer conditions are already in place, improving energy transfer efficiency without requiring complex real-time adjustments
Solution Approach 2:
The system controls overpressure wave characteristics by adjusting parameters such as coupling chamber dimensions, interface component properties, and detonator configuration. These parameter changes enable precise amplitude control and optimized energy transfer to the target media
3Measurement precision
If the overpressure wave generator is not constrained, then the device structure is simple, but the seismic echoes are increased and exploration precision is reduced
Solution Approach 1:
A vehicle platform serves as a counterweight and stabilizing structure for the overpressure wave generator. This platform constrains the generator's movement during operation, reducing unwanted vibrations and seismic echoes that would otherwise degrade exploration precision, while maintaining a relatively simple overall device structure

AI summary
An improved system for coupling a generated overpressure wave to a target media includes a coupling chamber and an interface between the coupling chamber and a target media. Pressure produced in the coupling chamber by a generated overpressure wave is applied to the interface thereby converting the pressure in the coupling chamber into a force that produces a conducted acoustic wave in the target media.
