Movable Shroud Connector for Tight-Space Plug Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circular plug connectors face challenges in making and releasing connections in tight spaces due to the limited space for tools or manual operation, as the actuating element is typically located near the connector end, making it difficult to access and use tools like torque wrenches.
Innovation Solution
A plug connector design where the casing extends over the entire length and serves as the actuating element, allowing for rotary or linear movement to establish, release, and secure connections, with tool interfaces positioned away from the connector end, enabling easier tool-based or manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuating element is located near the connector end, then the connector structure is compact, but the space for tool placement or manual operation is limited
Solution Approach 1:
The patent relocates the actuating element from the traditional radial position at the connector end to the longitudinal dimension along the connector body. The actuating element extends parallel to the connector axis, allowing tool engagement at multiple positions along its length, thereby resolving the contradiction between compact structure and operational accessibility.
Solution Approach 2:
The actuating element is divided into multiple functional sections: a first portion for tool engagement (e.g., hexagonal interface), a second portion for manual gripping, and a third portion that interfaces with the locking mechanism. This segmentation allows different operations to be performed at different locations, improving ease of operation without excessive complexity.
2Ease of operation
If multiple connectors are arranged close together, then the system is compact, but it becomes difficult to connect and/or disconnect connectors
Solution Approach 1:
The extended actuating element serves as an intermediary that provides multiple engagement points along its length. This allows tools or hands to access and operate the connector even when adjacent connectors are in close proximity, as the operational interface extends into the space between connectors rather than being confined to the connector end.
Solution Approach 2:
By extending the actuating element longitudinally along the connector body rather than positioning it radially at the end, the patent creates additional operational space in the longitudinal dimension. This allows connectors to be arranged more closely in radial directions while maintaining accessibility for connection operations.
3Ease of operation
If the operating level is at the connector end, then the plug connection is established efficiently, but tool-based operation is difficult in confined areas
Solution Approach 1:
The actuating element is designed with tool interfaces (e.g., hexagonal portions) positioned along its length before the final locking action occurs. This allows tools to be engaged and positioned in advance, and enables the operator to apply torque or force at optimal points during the connection sequence, maintaining efficiency while improving tool accessibility.
Solution Approach 2:
The patent shifts the operational interface from the radial dimension at the connector end to the longitudinal dimension along the connector body. This dimensional change allows tools to access the actuating element from directions that are more accessible in confined areas, while still enabling efficient plug connection establishment through the extended operational path.
