Angle Valve Locking Mechanism With Open-Close State Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angle valves in semiconductor processes lack a configuration to securely lock the stem in place, potentially leading to unintended release of the locked state, which can result in errors and damage to the valve seat.
Innovation Solution
An angle valve with a locking check function that includes a locking pin fixture, a rotating body with a coupling groove, a locking pin, and springs to limit rotational movement, along with an opening and closing display guide to visually indicate the valve's state, ensuring secure locking and easy recognition of the open or closed state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to prevent unintended release, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is divided into separate functional components: a locking pin (630) with a locking protrusion (632), a locking hole (613) in the locking pin fixture (610), and a rotating body (620) with a locking pin moving space (622). This segmentation allows each component to perform its specific function while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The locking pin (630) acts as an intermediary element between the rotating body (620) and the locking pin fixture (610). It transfers and limits rotational movement through the engagement of the locking protrusion (632) with the locking hole (613), providing reliable locking while keeping the structural design manageable.
2Ease of operation
If a visual display system is added to indicate valve state, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The opening and closing display guide portion (700) utilizes visual indication through positional changes rather than color changes. The display element shows different positions (open/closed states) by moving to different locations, providing clear visual feedback to operators while maintaining relatively simple construction.
Solution Approach 2:
The display system creates a visual copy or representation of the actual valve state. The opening and closing display guide portion (700) mirrors the positional state of the opening and closing blade (200) through the lifting pin (740) mechanism, providing intuitive visual feedback without requiring complex sensing or electronic systems.
3Reliability
If rotational movement is strictly limited, then reliability is improved, but ease of operation worsens
Solution Approach 1:
The locking mechanism employs dynamic characteristics where the locking pin (630) can move between locked and unlocked states. The locking pin moving space (622) allows the locking pin to shift position, enabling smooth transitions between operational states while maintaining secure locking when engaged, thus balancing reliability with operational ease.

Function Achieved in This Case
The solution allows for easy visual confirmation of the valve's state, preventing errors and ensuring secure operation by automatically displaying 'OPEN' or 'CLOSE', thus enhancing user convenience and preventing damage to the valve seat.
Implementation Method 1
a first spring 640 formed by winding the coupling protrusion 623, one side of which is in contact with an inner surface of the second seating space 511, and the other side of which is coupled to the locking pin 630 and pushes the locking protrusion 632 outward through elastic force
