Pressurized Fluid Valve With Nested Locking Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valves for pressurized fluid systems are susceptible to impacts, deformations, and unwanted intrusions, and lack ergonomic design in their locking mechanisms.
Innovation Solution
A valve design featuring a locking member with a gripping end housed within a fixed head, movable between retracted and projecting positions, and a rigid shell for protection, utilizing balls or claws for coupling and a spring-urged locking mechanism for secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the locking member is made accessible on the periphery of the valve, then it is easy to operate, but it is susceptible to impacts, deformations, and unwanted intrusions
Solution Approach 1:
The gripping end of the locking member is nested within the head of the valve body, specifically in a housing formed in the head. This nested configuration protects the locking mechanism from external impacts and deformations while maintaining operability through the defined movement paths within the housing.
Solution Approach 2:
The head of the valve body acts as a protective shell enclosing the gripping end of the locking member. This shell structure provides mechanical protection against unwanted intrusions and environmental factors while allowing controlled movement of the gripping end between retracted and extended positions.
2Object-affected harmful factors
If the gripping end is retracted into the head, then protection from impacts is improved, but ergonomic accessibility is reduced
Solution Approach 1:
The gripping end is designed to be dynamic, moving between a retracted position (when locking member is in first position) and an extended position (when locking member is in second position). This dynamic configuration allows the gripping end to be protected when not in use while being accessible when locking operations are required.
Solution Approach 2:
The housing in the head is pre-configured with sufficient space to accommodate the gripping end in both retracted and extended positions. This preliminary design ensures that the gripping end can be easily accessed when needed without requiring additional external space or complex mechanisms.
3Ease of operation
If the locking member is mounted movably on the body, then ease of locking/unlocking is improved, but susceptibility to unwanted body intrusion is increased
Solution Approach 1:
The locking member is nested within the body structure, with the gripping end housed in the head and the locking portion moving within the body cavity. This nested arrangement allows the locking member to move freely for locking operations while being protected from external contaminants and unwanted intrusions throughout its movement path.

AI summary
A valve for pressurized fluid housing a fluid circuit having an upstream end and a downstream end and a valve for controlling the flow rate in the circuit that is controlled by a movable actuating member in order to control the opening or the closing, the valve having a lower end provided with movable coupling member(s) intended to cooperate with one or more complementary coupling members on a gas source or a circuit, the valve further comprising a member for locking the coupling member(s) that is mounted movably on the body of the valve between a first position not blocking the movement of the coupling member(s) and a second position blocking the movement of the coupling member(s).
