Steering-Column Remote Control for Seismic Source Baseplate Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing controllers for land seismic source vehicles are ergonomically suboptimal and pose safety risks due to their large size and weight, requiring the driver to operate them while driving, and are prone to failure, leading to inefficiencies and costly interruptions during seismic data acquisition.
Innovation Solution
A remote control system is attached to the steering wheel column, allowing the driver to control the baseplate and vibratory seismic source without needing to view the controller, enhancing safety and efficiency by providing ergonomic access to all functionalities and allowing for easy replacement of failed components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is placed on the floor between driver and passenger seats, then all controller functionalities are accessible, but driver safety deteriorates due to need to view keyboard while driving
Solution Approach 1:
A remote control mechanism is introduced as an intermediary device that allows the driver to control the baseplate without directly operating the main controller keyboard. The remote control is mounted on the steering column within the driver's field of view, enabling control through a mediating interface that eliminates the need to look down at the keyboard while maintaining full operational capability
Solution Approach 2:
The control interface is relocated from the horizontal plane (floor-mounted keyboard requiring downward gaze) to the vertical dimension (steering column mounting within eye level). This dimensional change allows the driver to operate controls while maintaining forward vision, transforming the spatial relationship between driver and controller
2Adaptability or versatility
If the controller is large and heavy to provide all functionalities, then operational capability is improved, but ease of operation worsens due to placement requirements
Solution Approach 1:
The controller system is segmented into two distinct parts: the main controller unit containing all functional capabilities and the remote control mechanism providing ergonomic access. This segmentation allows the heavy main controller to be positioned optimally for functionality while the lightweight remote provides accessible control points near the driver
Solution Approach 2:
The remote control acts as an intermediary interface that provides all controller functionalities through a simplified, ergonomically positioned control set. The remote transmits commands to the main controller, allowing full operational capability to be accessed through a lightweight, easily reachable interface
3Adaptability or versatility
If the controller is positioned for full functionality access, then operational capability is improved, but reliability worsens due to proximity to driver and vibration
Solution Approach 1:
The controller system is divided into the main controller unit and remote control mechanism. The main controller can be positioned in a more protected, vibration-isolated location while the remote provides the operational interface near the driver, separating the vulnerable components from high-stress environments
Solution Approach 2:
The remote control mechanism serves as an intermediary that protects the main controller from direct exposure to driver-induced vibrations and environmental factors. The remote transmits control signals to the main controller through a protected interface, reducing the risk of failure from mechanical stress
Data Source
AI summary
A remote control system for a vibratory seismic source that generates seismic signals. The remote control system includes an attachment mechanism configured to be fixedly attached to a component of a vehicle carrier that carries the vibratory seismic source, and a remote control mechanism supported by the attachment mechanism, wherein the remote control mechanism includes first and second command units, each configured to control a baseplate associated with the vibratory seismic source. Each of the first and second command units are configured to be removed from the remote control mechanism while the attachment mechanism is hold in place.
