Solution Overview
Problem
Seismic surveying technologies face challenges in accurately measuring rotation data, which is essential for noise attenuation and data processing, as existing systems often require separate rotational sensors and are prone to damage during deployment due to uneven force distribution.
Innovation Solution
A sensor device with an elongated housing containing particle motion sensors spaced along its longitudinal axis, coupled with a load transfer mechanism that includes an impact surface and connector structure to distribute deployment forces away from sensitive electronic circuitry, allowing for the derivation of rotation data from translational measurements without additional rotational sensors and protecting the circuitry during deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate rotational sensors are used to measure rotation data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines rotational measurement capability with the existing particle motion sensor system by strategically spacing sensors along the longitudinal axis. The rotation data is derived through computational methods using the translational measurements from the spaced sensors, eliminating the need for separate rotational sensors while maintaining measurement precision.
Solution Approach 2:
The particle motion sensors serve dual functions: they measure both translational particle motion and, through their spatial arrangement and computational processing, rotational components. This multi-functionality allows the same sensor system to provide both types of data without requiring additional specialized rotational sensors.
2Productivity
If impact force is applied directly to the sensor device during deployment, then productivity is improved, but reliability deteriorates due to damage from uneven force distribution
Solution Approach 1:
The patent introduces an intermediary structure (the elongated housing with spaced sensors and protective casing) between the impact force and the sensitive electronic circuitry. This intermediary structure absorbs and distributes the impact force along the longitudinal axis, protecting the electronic components from direct exposure to uneven deployment forces while still enabling rapid deployment.
Solution Approach 2:
The sensor device is segmented into distinct functional zones: the elongated housing containing particle motion sensors, the electronic circuitry portion, and the impact reception structure. This segmentation allows the impact force to be applied to the housing while the electronic components are protected in a separate, more vulnerable section, maintaining both deployment speed and component reliability.

AI summary
A sensor device includes an elongated housing containing particle motion sensors spaced apart along a longitudinal axis of the elongated housing, where the elongated housing has a width. A second portion includes communication circuitry to communicate over a communication medium, the second portion coupled to the elongated housing and having a width that is greater than the width of the elongated housing. The second portion includes an impact surface that is above a top surface of the second portion, the impact surface to receive an impact force for deploying the sensor device into a ground surface. The second portion further includes a connector structure to mechanically connect the impact surface to the elongated housing.
