Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pneumatically actuated switching devices for patient call systems face issues with the pneumatic hose connection to the housing becoming loosened or disconnected, leading to loss of pressurized air and unreliable operation.
Innovation Solution
A pneumatic hose connection member with an enlarged portion for flush assembly, a threaded section for attachment, and an elongated section with anchor thugs for secure attachment of the pneumatic hose, along with gripping elements for easy installation and removal, ensuring a secure and reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pneumatic hose connection member is designed to be secure and resistant to dislodging, then the reliability of pressurized air delivery is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The pneumatic hose connection member is divided into distinct functional segments: a threaded section for secure attachment to the housing, an enlarged portion for alignment and flush assembly, and an elongated section with anchor thugs for hose attachment. This segmentation allows each portion to contribute specifically to either connection stability or ease of installation, resolving the contradiction between secure connection and easy installation.
2Reliability
If the pneumatic hose connection member includes multiple attachment features (threaded section, anchor thugs), then the security of pressurized air delivery is improved, but the device complexity increases
Solution Approach 1:
Multiple attachment features (threaded section for housing attachment, anchor thugs for hose attachment, enlarged portion for alignment) are merged into a single integrated pneumatic hose connection member. This consolidation provides secure pressurized air delivery through multiple mechanisms while avoiding the complexity of separate components, as all features work together as one unified structure.
3Ease of repair
If the pneumatic hose connection member is designed for easy removal and reinstallation, then the ease of maintenance is improved, but the reliability of connection may deteriorate
Solution Approach 1:
The connection member is pre-designed with threaded sections and anchor thugs that create secure attachment points before use. These preliminary structural features ensure that when the connection is made, it is inherently reliable and resistant to dislodging, while still allowing for straightforward removal and reinstallation when maintenance is needed.

AI summary
In a pneumatically actuated switching device having a pneumatic actuator for delivering pressurized air to a switch assembly for generating an electrical signal, the switch assembly comprises a switch housing having a conductive element for opening and closing a circuit; and a pneumatic hose connection member removably mounted to the housing for connecting a pneumatic hose to the housing for delivering the pressurized air for generating the electrical signal. The pneumatic hose connection member has an enlarged portion flushed with the housing, a first extended portion having a threaded section for attachment to the housing, and a second extended portion having a plurality of anchor thugs for securing the pneumatic hose. The housing and pneumatic hose connection member have a plurality of gripping elements for facilitating the insertion and removal of the pneumatic hose connection member relative to the housing and the attachment and detachment of the pneumatic hose.
