Adapter Plate Snap-Lug Coupling for Fast Valve Controller Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control valves for water treatment systems require complex and time-consuming processes to remove and reattach the controller, which can lead to damage and increased operational costs due to the need for manual labor.
Innovation Solution
An adapter plate with retention stops, snaps, and lugs facilitates quick and safe attachment and detachment of the controller to the valve body using a combination of axial movement and rotational mechanisms, ensuring secure coupling through retention slots and snaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is directly mounted to the valve body using conventional methods, then the controller is securely attached, but the removal and reattachment process becomes complicated and time-consuming
Solution Approach 1:
The coupling mechanism is divided into separate components: a coupling member with retention arms and a coupling structure with retention slots. This segmentation allows the controller to be quickly attached and detached by simply engaging and disengaging these modular components, eliminating complicated assembly procedures and reducing maintenance time.
Solution Approach 2:
The coupling member acts as an intermediary component between the controller and valve body. It provides a dedicated interface with retention arms that engage with retention slots, facilitating easy attachment and detachment without requiring direct complex fastening between the controller and valve body.
2Reliability
If the controller is securely fastened to the valve body, then the connection is reliable, but the removal process risks damage to controller electronics and valve body components
Solution Approach 1:
The coupling mechanism separates the retention function into distinct retention arms and retention slots. This segmentation allows for controlled engagement and disengagement, where the retention arms can be easily released from the slots without applying excessive force that could damage sensitive electronics or valve body components.
Solution Approach 2:
The coupling member is pre-configured with retention arms positioned to engage with retention slots on the coupling structure. This preliminary arrangement ensures that when the controller is attached, the retention arms are already in the correct position to provide secure holding without requiring additional fastening steps that could increase damage risk during removal.
3Productivity
If a simple attachment mechanism is used, then the attachment process is quick, but the connection may not be secure enough to prevent damage during operation
Solution Approach 1:
The coupling mechanism uses multiple retention arms (first and second retention arms) that engage with corresponding retention slots. This segmented multi-point connection provides secure holding during operation while maintaining the ability to quickly disengage all retention arms simultaneously for rapid maintenance operations.
Solution Approach 2:
The coupling member and coupling structure are designed to allow dynamic engagement and disengagement. The retention arms can be easily moved into and out of the retention slots, providing a connection that is both secure during normal operation and quickly releasible when maintenance is needed, balancing productivity and reliability.

AI summary
An adapter plate is provided for coupling a controller to a port of a valve, comprising: mounting tabs; an outer wall; retainer lugs and retention slots extending radially inward from the outer wall; and notches extending radially outward into the outer wall and spaced to align with snaps of the port. When the notches are aligned with the snaps, each retainer lug is positioned between a valve lug of the port and a snap, permitting the notches to pass over the snaps as the adapter plate is moved axially onto the port into an engaged position. The retention slots are configured to flex the snaps radially inward as the adapter plate is rotated from the engaged position to a seated position in which the snaps seat within the retention slots. The mounting tabs are configured to mate with connection snaps on the controller to couple the controller to the valve.
