Hydraulic Coupling Holder for Clean Disconnected Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic connector systems for work vehicles fail to adequately protect movable connector parts when disconnected, leading to dirt accumulation and potential damage, as they lack protection for both fixed and movable connector parts during operation and storage.
Innovation Solution
A holding means is designed on the work equipment to securely fit and protect the movable connector part, featuring a contact surface that mates with the connector, keeping it clean and protected from environmental hazards, and a cover is provided to safeguard the fixed connector part when not in use, minimizing dirt collection and impact risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable connector part is left exposed during operation, then it is accessible for connection, but it accumulates dirt and requires cleaning before connection to the fixed connector part
Solution Approach 1:
The holding means is pre-configured with a contact surface that mates with the movable connector part. When the movable connector part is disconnected, it is automatically positioned in the holding means, which preliminarily protects it from dirt accumulation before the next connection operation is required
Solution Approach 2:
The movable connector part is nested within or against the holding means structure, where the contact surface provides a protective interface. This nesting arrangement allows the movable connector part to be housed in a protected position when not in use, similar to how nested dolls provide protective enclosures
2Adaptability or versatility
If individual quick couplings are used for each hydraulic connection, then each connection can be made individually, but the complexity of the connector system increases
Solution Approach 1:
The holding means is designed as a universal structure that can accommodate and protect the movable connector part regardless of whether it is a single coupling or a multi-coupling assembly. This multi-functional design allows the same protective arrangement to work with different connector configurations, reducing overall system complexity
