Solution Overview

Problem

The existing link connector systems for rig equipment require multiple sets of links of varying lengths, leading to significant space consumption on limited rigs, as they cannot efficiently accommodate different length and size requirements.

Innovation Solution

A link connector system comprising a body with pivotably coupled blocking members that secure eyelets of links in an '8' shape configuration, allowing for adjustable length and load rating connections, reducing the number of links needed and optimizing storage space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sets of links of various lengths are required to accommodate different rig operation needs, then the adaptability is improved, but the space occupied on the rig increases significantly

Engineering Contradiction:
ImproveadaptabilityVSAvoidspace occupied
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The link connector is designed as a universal connecting device that can join links of different lengths and configurations. The connector body with opposing openings and blocking members creates a standardized interface that works with various link types, eliminating the need for multiple specialized link sets and reducing overall space requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The link connector design allows compact storage by enabling links to be nested or stacked together when not in use. The connector's structure with interlocking blocking members and body creates a compact assembly that minimizes the volume occupied on the rig while maintaining full functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of stationary object

If the number of link sets is reduced to save space, then the space occupied is reduced, but the ability to accommodate different length and size requirements deteriorates

Engineering Contradiction:
Improvespace occupiedVSAvoidadaptability
Core Design Contradiction:
Volume of stationary objectVSAdaptability or versatility

Solution Approach 1:

The link connector serves multiple functions: it connects links of different lengths, joins links of various sizes, and provides a standardized interface for different rig operations. This multi-functionality allows a reduced number of link sets to still meet diverse operational requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The blocking members are designed to be movable relative to the connector body, allowing dynamic adjustment between open and closed positions. This enables flexible insertion and removal of links while maintaining secure connections, adapting to different link configurations as needed.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If blocking members are made movable to enable easy connection and disconnection, then the ease of operation is improved, but the structural complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The blocking members are designed as movable components that can pivot or slide between open and closed positions. This dynamic capability allows operators to easily insert and remove links by simply moving the blocking members, significantly improving ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The link connector is divided into distinct functional segments: the body with openings, the blocking members, and the pin members. This segmentation allows each component to perform its specific function independently, simplifying the overall design while maintaining ease of operation through the movable blocking members.

Inventive Principle:
Principle #1Segmentation

AI summary

A link connector (200) configured to connect a set of links (100a, 100b) together. The link connector has a body (210) having an upper portion and a lower portion. A first blocking member (220) is pivotably coupled to the upper portion of the body by a pin member. A second blocking member (230) is pivotably coupled to the lower portion of the body by a pin member. The first and second blocking members are movable between an open position and a closed position such that when in the closed position the link connector forms an 8 shape.
