Plug Connector Closure with Translational Release and Full Contact Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for electrical connectors, such as those used in electromobility charging stations, do not provide intuitive operation and fail to adequately protect all electrical contact elements, often requiring cumbersome rotational movements and partial coverage.
Innovation Solution
A locking device with a translationally movable release element and a coupling element that interacts with cover elements, allowing for intuitive operation by translational movement of the mating connector, ensuring complete coverage of electrical contact elements without rotational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a closure device is provided that is removable from the distal end of a catheter, then the catheter can be delivered through the aorta and iliac arteries to the renal artery, but the closure device may embolize in the iliac artery or be inadvertently delivered to the renal artery causing renal artery occlusion
Solution Approach 1:
A retention member is introduced as an intermediary component between the closure device and the delivery system. This retention member engages with the closure device in a locked position during delivery through the aorta and iliac arteries, preventing premature embolization or misdelivery to the renal artery. Upon reaching the renal artery, the retention member is released, allowing the closure device to be deployed at the intended location.
2Reliability
If the closure device is held in a locked position during delivery, then delivery through major arteries is safe, but the closure device cannot be released to perform its closing function
Solution Approach 1:
The retention member transitions from a static locked position during delivery to a released state at the target location. The system dynamically changes state: the retention member engages the closure device in a locked configuration for safe passage through the aorta and iliac arteries, then releases at the renal artery to allow the closure device to perform its closing function on the renal artery.
3Volume of moving object
If the closure device is made small enough to pass through the delivery catheter, then it can be delivered to the renal artery, but it may become lost or embolize in the iliac artery before reaching the target
Solution Approach 1:
The retention member serves as a protective intermediary that temporarily holds the small closure device during transit through the delivery system. This intermediary component prevents the small closure device from becoming lost or embolizing in the iliac artery by securing it in a locked position until the catheter reaches the renal artery, where the retention member is released.
