Electrical Contactor Phase Separator Elastic Unlocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical contactors face difficulties in easily dismantling phase separators due to their compact design, which often prevents operators from accessing the unlocking mechanism with their fingers, potentially leading to safety issues and increased risk of fires during electrical current cut-offs.
Innovation Solution
An electrical contactor design that incorporates an elastic unlocking member arranged to unlock the phase separator when compressed against the cut-off box, allowing for easy removal without finger access, featuring a locking shoulder and elastic finger mechanism that deactivates the locking means upon compression, facilitating the disassembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electrical contactor is designed with a compact structure, then the device size is reduced and space is saved, but the operator cannot access the unlocking mechanism with fingers, making dismantling difficult
Solution Approach 1:
A pushing member is introduced as an intermediary tool between the operator and the unlocking mechanism. This pushing member can be inserted through a delivery opening to actuate the unlocking member, allowing the operator to dismantle the separator without direct finger access to the locking mechanism, thus resolving the contradiction between compact design and ease of dismantling
Solution Approach 2:
The unlocking mechanism is accessed through a different spatial dimension - the delivery opening provides an alternative access path rather than requiring direct lateral access to the unlocking member. This allows the compact design to be maintained while providing remote actuation capability for dismantling
2Stability of the object's composition
If the separator is permanently mounted on the base, then the structural integrity is improved, but the separator cannot be removed for maintenance or replacement
Solution Approach 1:
The locking mechanism transitions from a static permanent mounting to a dynamic selectively lockable system. The unlocking member can engage or disengage the locking protrusion based on actuation, allowing the separator to be securely mounted during operation but easily removed when needed, thus achieving both structural integrity and adaptability
Solution Approach 2:
The pushing member is designed to be simple and tool-free, allowing operators to perform maintenance and replacement operations themselves without requiring specialized tools or complex procedures. The elastic nature of the pushing member provides self-contained functionality for actuating the unlock mechanism
3Ease of operation
If the unlocking mechanism requires direct finger access, then the unlocking action is simple, but the compact design prevents operator access to the mechanism
Solution Approach 1:
The pushing member serves as a mediator that translates simple linear pushing motion into the rotational or linear displacement needed to actuate the unlocking member. This maintains the simplicity of the unlocking action while accommodating the compact device geometry that prevents direct finger access
