Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual hammering mode is used as the seismic source, then the device structure is simple, but the data quality consistency and energy consistency of each excitation cannot be ensured
Solution Approach 1:
The patent replaces the manual mechanical hammering system with an electromagnetic accelerator system. The electromagnetic accelerator uses electromagnetic fields to accelerate a mass, generating controlled seismic waves. This substitution of mechanical manual operation with an electromagnetic system enables precise control over the seismic source characteristics, ensuring consistent energy and data quality across all excitations while maintaining relatively simple device structure.
2Device complexity
If the wave detector is plugged into the ground manually, then the device structure is simple, but the coupling effect is poor when ground hardness is high
Solution Approach 1:
The patent replaces the manual plugging mechanism with an electromagnetic-driven insertion system. The electromagnetic accelerator not only generates seismic waves but also provides the driving force to push the wave detector into the ground. This electromagnetic assistance overcomes the high ground hardness barrier, ensuring reliable coupling between the wave detector and the ground while keeping the overall device structure simple.
3Area of stationary object
If the seismic source hammer, host and wave detector are carried to move when detecting point moves, then the detection coverage is expanded, but time and labor are wasted
Solution Approach 1:
The patent merges the seismic source hammer, host, and wave detector into a single integrated device. This unified structure allows the entire system to be positioned at each detecting point as one unit, eliminating the need to separately transport and coordinate multiple components. The integrated design maintains full detection coverage capability while significantly reducing the time and labor required for repositioning between measurement points.
4Manufacturing precision
If electromagnetic accelerators are used for controlled acceleration, then the seismic source quality is ensured, but the device complexity increases
Solution Approach 1:
The patent designs the electromagnetic accelerator system to serve multiple functions: it acts as both the seismic source generator and the driving mechanism for inserting the wave detector into the ground. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while still ensuring high seismic source quality through controlled electromagnetic acceleration.
