Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick connector assemblies in vehicle pipeline systems fail to prevent liquid from flowing out during plugging and unplugging, and they struggle to achieve a reliable check function simultaneously.
Innovation Solution
A quick connector with a two-way check mechanism, featuring a first plugging block, a second plugging block, and elastic members, along with an ejector rod, which allows for sealing and unsealing of the connection to prevent liquid flow when plugging and unplugging, utilizing a combination of sealing rings and guide structures for effective sealing and flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick connector and quick plug are separated during plugging process, then quick-plug function is achieved, but liquid flows out from the pipeline
Solution Approach 1:
The check mechanism is activated in advance before the quick plug is fully inserted or removed. When the quick plug is pulled out, the check mechanism automatically closes the pipeline opening before liquid can flow out. When the quick plug is inserted, the check mechanism opens the pipeline opening in advance to allow liquid flow. This preliminary action prevents liquid leakage while maintaining quick connection capability.
Solution Approach 2:
The check mechanism acts as an intermediary between the quick connector and the pipeline. It includes a check body with a check cavity, a first check component with a first sealing ring, and a second check component with a second sealing ring. These components mediate the connection and disconnection processes by controlling the opening and closing of the pipeline, preventing liquid from flowing out during the quick-plug operation.
2Object-generated harmful factors
If a check structure is added to prevent liquid flow, then liquid leakage is prevented, but the check function cannot be achieved simultaneously for both quick connector and quick plug
Solution Approach 1:
The check mechanism is divided into two independent check components: a first check component (with first sealing ring) for checking the quick connector, and a second check component (with second sealing ring) for checking the quick plug. Each check component can function independently to prevent liquid leakage at its respective location. This segmentation allows both the quick connector and quick plug to achieve reliable check functions simultaneously without interfering with each other.
3Object-generated harmful factors
If sealing rings are added to achieve sealing function, then liquid leakage is prevented, but the structure complexity increases
Solution Approach 1:
The check mechanism uses universal sealing components that serve multiple functions. The first sealing ring on the first check component and the second sealing ring on the second check component not only provide sealing functions to prevent liquid leakage but also serve as the check components themselves. The sealing rings are integrated into the check components, combining sealing and checking functions in a single element, thereby reducing overall structural complexity while achieving reliable liquid leakage prevention.
