Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seismic survey technologies face challenges in accurately recording three-axis seismic data due to the high cost and cumbersome deployment of triaxial sensors, which are necessary for precise ground motion recording, and the inability to efficiently convert single-component sensors into a three-component configuration for field deployment.
Innovation Solution
A 3-axis seismic sensor stake system that allows for the conversion of three independent seismic sensors into a single three-axis unit by using a stake with angled ends and retaining members to securely orient and attach sensors along orthogonal axes, enabling precise and cost-effective seismic data collection without external housing or complex cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If triaxial sensors are used to accurately record three-axis seismic data, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the three-axis sensing function into three separate single-component sensors, each measuring one axis independently. These segmented sensors are then mounted on a common stake structure, allowing complex 3D seismic data collection through simple, modular components rather than a single complex triaxial sensor.
Solution Approach 2:
The patent combines three independent single-component sensors onto a single stake structure with common mounting and grounding. This merging approach allows the system to function as an integrated three-component sensor while using simpler, more affordable individual sensor units.
2Reliability
If triaxial sensors are deployed to ensure data consistency across all axes, then reliability is improved, but ease of operation deteriorates due to cumbersome deployment
Solution Approach 1:
The stake structure serves multiple functions: it provides a common mounting platform for all three sensors, ensures orthogonal alignment through its geometric design, provides shared grounding, and enables rapid deployment. This multi-functional design eliminates the need for separate mounting hardware and alignment procedures for each sensor.
Solution Approach 2:
The stake is pre-configured with mounting features and geometric constraints that automatically ensure proper orthogonal alignment of sensors when mounted. This preliminary preparation eliminates the need for complex field alignment procedures and ensures consistent sensor orientation during deployment.
3Quantity of substance
If three independent sensors are used instead of a single triaxial sensor, then cost is reduced, but device complexity increases due to separate housing and cabling requirements
Solution Approach 1:
The patent merges three separate sensor units onto a single stake structure, eliminating the need for three separate housings and cabling systems. The common stake serves as the structural platform for all sensors, and the shared grounding system reduces cabling complexity while maintaining individual sensor functionality.
Solution Approach 2:
The stake structure performs multiple functions simultaneously: structural support, sensor mounting, alignment reference, and grounding. This multi-functionality eliminates the need for separate housing and cabling infrastructure that would otherwise be required for three independent sensors.
4Reliability
If sensors are permanently installed in a single container housing, then reliability is improved through consistent recording, but portability and ease of deployment deteriorate
Solution Approach 1:
The patent segments the sensor system from traditional permanent housing into a portable stake configuration. The sensors are mounted on a lightweight stake that can be rapidly deployed and repositioned, while the geometric constraints of the stake maintain consistent orthogonal alignment comparable to permanent installations.
Solution Approach 2:
The system transitions from static permanent housing to a dynamic, portable stake configuration that can be easily deployed, repositioned, and reconfigured in the field. The stake's geometric design ensures that despite its mobility, the sensor alignment remains consistent and reliable.

AI summary
A seismic sensor stake, system and method configured to orientate three seismic 1C sensors orthogonally in the X, Y, and Z directions. The present technology stake is configured to efficiently and effectively convert three independent seismic sensors into a single three seismic sensor unit. Multiple stakes can be inserted into the ground of a geographical area to provide highly accurate seismic survey of subterranean hydrocarbon formations. Each seismic sensor can include a slot that slidable receives a threaded member of a mounting sides of the stake. A retaining nut can secure the seismic sensor in place upon rotation of the sensor. A stake bit can be utilized with an impact hammer to form holes in hard or frozen ground for quick insertion of the stake into the ground.
