Cable Latch Attachment for Fast Secure Seismic Node Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cable attachment systems for seismic surveys and other applications are time-consuming and prone to equipment losses due to improper coupling, necessitating improved methods for securely and efficiently attaching objects to ropes or cables.
Innovation Solution
A coupling mechanism featuring a latch block and coupling feature that securely attaches external devices to a rope or cable, allowing for quick attachment and detachment, with a latch member that selectively engages a swage button or canted spring on the cable, enabling rotation and pivoting movements to prevent damage during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable attachment systems are used, then equipment can be attached to cables, but the attachment process is time-consuming and prone to equipment losses
Solution Approach 1:
The attachment system is divided into separate components: a coupling mechanism with latch block that attaches to the cable, and a separate device to be attached. This segmentation allows for quick connection and disconnection without complex procedures, reducing attachment time while maintaining security through the latch mechanism
Solution Approach 2:
The coupling mechanism incorporates a self-latching feature where the latch block automatically engages with the cable attachment feature when brought together, reducing the need for manual intervention and complex attachment procedures, thereby saving time while ensuring secure attachment
2Reliability
If traditional cable attachment systems are used, then equipment can be attached to cables, but improper coupling procedures can lead to equipment losses
Solution Approach 1:
The self-latching coupling mechanism automatically secures the device to the cable when the attachment features are brought together, eliminating the need for complex manual coupling procedures. This reduces the risk of improper attachment while maintaining ease of operation
Solution Approach 2:
The coupling mechanism is designed as a robust, standardized component that can be easily replaced if damaged, rather than attempting to repair complex attachment systems. This ensures reliable attachment through simple, proven mechanics while reducing operational complexity
3Reliability
If a secure attachment system is implemented, then equipment losses are reduced, but the system complexity increases
Solution Approach 1:
The attachment system uses simple, discrete components (latch block, cable attachment feature) rather than a complex integrated system. This segmentation maintains reliability through focused functionality while reducing overall system complexity and ease of manufacture
Solution Approach 2:
The latching function is extracted as a separate, simple mechanical feature of the latch block rather than being integrated into a complex attachment system. This simplifies the overall structure while maintaining secure equipment retention

AI summary
An attachment system for securing an object, such as a seismic node or other external device, to a rope or cable includes a latch block and a latch member movably connected to the latch block for selective engagement with a coupling feature on the rope or cable. The latch block may be attached to or integrated with the object and can include opposing side members defining a channel extending through the latch block, the channel sized for selective receipt of the rope or cable therein. The latch member may selectively engage the coupling feature as the rope or cable is received in sliding engagement within the channel.
