Solution Overview
Problem
High-density seismic acquisitions face challenges with poor data quality due to substandard coupling of seismic sensors with the ground, as manual deployment is inefficient and complex machinery-based solutions require accessible locations, which may not always be feasible.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual planting of seismic sensors is performed, then good coupling with the ground is achieved, but deployment efficiency is too low for high density acquisitions
Solution Approach 1:
The sensor device automatically releases the coupling material when it contacts the ground, eliminating the need for manual intervention. The device self-services by detecting ground contact through the impact event and autonomously deploying the coupling material to ensure proper coupling.
Solution Approach 2:
The coupling material is pre-loaded in the bottom section of the sensor device before deployment. This preliminary preparation allows the device to immediately release the coupling material upon ground contact, ensuring proper coupling without requiring manual intervention during the critical coupling phase.
2Productivity
If sensors are dropped on the ground for high density acquisitions, then deployment efficiency is improved, but coupling quality deteriorates
Solution Approach 1:
The sensor device automatically releases the coupling material when it contacts the ground, eliminating the need for manual intervention. The device self-services by detecting ground contact through the impact event and autonomously deploying the coupling material to ensure proper coupling.
Solution Approach 2:
The coupling material is pre-loaded in the bottom section of the sensor device before deployment. This preliminary preparation allows the device to immediately release the coupling material upon ground contact, ensuring proper coupling without requiring manual intervention during the critical coupling phase.
3Reliability
If machine-based trench deployment is used, then coupling quality is improved, but system complexity and accessibility requirements increase
Solution Approach 1:
The sensor device automatically releases the coupling material when it contacts the ground, eliminating the need for manual intervention. The device self-services by detecting ground contact through the impact event and autonomously deploying the coupling material to ensure proper coupling.
Solution Approach 2:
The complex trench-digging machinery is removed from the deployment system. Instead, a simple free-fall deployment mechanism is used, with the coupling material function extracted and integrated directly into the sensor device itself, allowing deployment in previously inaccessible areas.
