Solution Overview

Problem

Existing disconnect terminal arrangements require complex and cumbersome processes to separately switch individual switching devices, as common coupling devices are difficult to detach from switching levers.

Innovation Solution

A coupling device with a connecting member that is adjustable along an alignment direction, allowing for a simple and user-friendly coupling and decoupling of switching devices between a coupling and release position, enabling joint or independent operation of multiple disconnect terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a coupling device is used to mechanically couple switching devices together, then joint actuation of multiple disconnect terminals is enabled, but the coupling device becomes difficult to detach and requires complex dismantling processes for separate switching

Engineering Contradiction:
Improvejoint actuationVSAvoiddismantling complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connecting member is designed to be adjustable between a coupled position (where it connects the switching levers) and a decoupled position (where it is detached). This dynamic adjustability allows the coupling device to transition from a fixed connection to a removable connection, enabling both joint actuation and easy separation without complex dismantling procedures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connecting member acts as an intermediary element between the switching levers. It can be inserted to couple the levers together for joint actuation, and removed to allow separate actuation. This intermediary component mediates between the need for coupling and the need for separability, simplifying the overall operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a connector is firmly connected to switching levers, then reliable mechanical coupling is achieved, but the connector cannot be easily removed for independent switching operations

Engineering Contradiction:
Improvecoupling reliabilityVSAvoidseparation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connecting member transitions from a static firmly-connected design to a dynamic adjustable design. It can be positioned to firmly connect the switching levers when coupling is needed, and easily moved to a detached position when separation is needed, maintaining both reliability and ease of operation

Inventive Principle:
Principle #15Dynamics
