Switchgear Motor Operator Quick Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor operators for switchgear units are cumbersome to remove and often misplaced due to confined spaces, leading to potential loss during relocation from a use position to a stowed position.
Innovation Solution
A quick coupling mechanism with a latch mechanism and indexing system allows the motor operator to be releasably secured and selectively positioned between a stowed position and a use position, featuring a support plate, guide tube, and cylinder assembly with a motor mount, enabling easy alignment and secure coupling to the switchgear unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor operator is removed from the switchgear unit, then the motor operator can be stowed elsewhere, but the motor operator may be misplaced or lost during removal and relocation
Solution Approach 1:
The coupling mechanism is divided into separate components: a coupling element on the motor operator and a corresponding receptacle on the switchgear unit. This segmentation allows the motor operator to be easily detached and reattached while maintaining secure connection during operation, resolving the contradiction between ease of removal and prevention of loss.
Solution Approach 2:
The coupling mechanism acts as an intermediary between the motor operator and switchgear unit. It provides a dedicated interface that ensures the motor operator can be easily removed for stowing while preventing misplacement through the structured coupling and recess design that guides proper reattachment.
2Reliability
If the motor operator is securely attached to the switchgear unit, then the motor operator can be reliably positioned, but the motor operator cannot be easily removed for stowing
Solution Approach 1:
The coupling mechanism transitions between two dynamic states: engaged and disengaged. During operation, the coupling element is inserted into the receptacle to provide secure attachment. When stowing is needed, the coupling can be easily disengaged by withdrawing the motor operator, allowing smooth transition between secured and removable states without compromising either reliability or ease of operation.
3Volume of moving object
If the motor operator is positioned in confined spaces around the switchgear unit, then the motor operator can be stored nearby, but the confined space makes removal and relocation burdensome
Solution Approach 1:
By segmenting the coupling into a separate coupling element and receptacle, the motor operator can be easily detached from the switchgear unit even in confined spaces. The modular design allows operators to remove and relocate the motor operator without the burdensome handling that would result from integrated or fixed mounting arrangements.

AI summary
A motor operator assembly is described, which is releasably secured and selectively coupled to a switchgear unit. The motor operator assembly includes a support plate, and a latch mechanism secured to the support plate that has a latch member configured to releasably secure the support plate to the switchgear unit. A guide tube is secured to the support plate and includes a cylinder assembly having a motor mount and an indexing mechanism for selectively positioning the cylinder assembly between a stowed position and a use position. A motor operator is attached to the motor mount and has a socket configured to engage an input drive shaft on the switchgear unit.
