Rotatable Solenoid Connector Cap for Flexible Valve Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solenoid valve assemblies for hazardous environments require fixed orientation connectors, leading to multiple connection points that increase failure risk and complicate component replacement, limiting versatility and adaptability.
Innovation Solution
A solenoid component with a configurable connector cap that allows multiple orientations through rotation about longitudinal and transverse axes, minimizing the need for explosion-proof fittings and facilitating easier component access and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed orientation connectors are used to meet safety requirements in hazardous environments, then safety and operational requirements are satisfied, but the number of connection points increases leading to higher failure risk and reduced versatility
Solution Approach 1:
The connector cap is designed with multiple connection openings (first opening, second opening, third opening) that can be configured in different orientations through rotation about longitudinal and transverse axes. This universal design allows a single connector cap to serve multiple connection purposes that would otherwise require multiple fixed connectors, thereby improving versatility while maintaining safety through reduced connection points
Solution Approach 2:
The connector cap is made rotatable relative to the solenoid base about both longitudinal and transverse axes, allowing dynamic reconfiguration of connection openings to match different installation orientations and usage scenarios. This dynamic adaptability enables a single connector to replace multiple fixed connectors, reducing the overall number of connection points and potential failure risks
2Reliability
If fixed configuration connectors are used, then safety requirements are met, but component replacement becomes difficult requiring removal of multiple connections
Solution Approach 1:
The rotatable connector cap allows maintenance personnel to easily reconfigure connection openings to accessible positions during replacement operations, eliminating the need to remove multiple fixed connections. The dynamic reconfiguration capability simplifies access to internal components while maintaining the safety integrity of the hazardous environment sealing
3Adaptability or versatility
If multiple electrical connection fittings are used to achieve desired connection paths, then connection flexibility is improved, but the number of connection points increases creating added failure risks
Solution Approach 1:
Multiple connection openings (first, second, and third openings) are integrated into a single connector cap structure that rotates as one unit. This merging of multiple connection functions into a single rotatable component provides the flexibility of multiple connectors while reducing the actual number of separate connection points to the valve body, thereby minimizing potential failure risks in hazardous environments

AI summary
A valve assembly includes a valve body that houses valve components for controlling a flow of fluid through the valve body, and a solenoid component that controls operation of the valve components. The solenoid component includes a connector cap that is attached to a solenoid base, the connector cap having a plurality of electrical connection openings oriented at different directions that are configurable at multiple orientations corresponding to different directions connection paths with the solenoid component. The solenoid component is rotatable about a longitudinal axis relative to the valve body to configure the electrical connection openings at one of multiple first orientations corresponding to a rotational position of the solenoid component relative to the valve body. The connector cap is rotatable about a transverse axis relative to the solenoid base to configure the electrical connection openings at one of multiple second orientations corresponding to a rotational position of the connector cap relative to the solenoid base.
