Enteral Feeding Pump Roller Assembly Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional enteral feeding pumps have rollers that are difficult to install, remove, clean, and maintain due to their fixed connection with screws and other fasteners, requiring tools and complicating maintenance processes.
Innovation Solution
A roller assembly with a locking structure that includes a switch member and a locking member, allowing for easy assembly and disassembly without tools, facilitating cleaning and maintenance by enabling the roller assembly to be securely locked and unlocked on the pump main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screws and fasteners are used to connect the roller to the pump main body, then the connection is secure and reliable, but the installation and removal process becomes complex and requires tools
Solution Approach 1:
The roller assembly is divided into separate components (roller body, end caps, locking members) that can be independently assembled and disassembled. The locking structure uses separate locking members that engage with positioning grooves, allowing the roller to be segmented for easy removal while maintaining secure connection during operation
Solution Approach 2:
The locking structure employs movable locking members that can transition between locked and unlocked states. The locking members are designed to move along guide grooves and engage/disengage from positioning grooves dynamically, enabling tool-free installation and removal while maintaining reliable connection when locked
2Stability of the object's composition
If the roller is firmly fixed to the pump main body, then operational stability is improved, but maintenance and cleaning become difficult
Solution Approach 1:
The locking structure is pre-configured with locking members and positioning grooves that enable quick release. The design anticipates maintenance needs by incorporating a switch member that can trigger the locking members to release, allowing the roller to be removed for cleaning without complex disassembly procedures
Solution Approach 2:
The roller assembly can be completely extracted from the pump main body by actuating the switching mechanism. The locking members are designed to disengage from the positioning grooves, allowing the roller to be fully removed for thorough cleaning and maintenance, then easily reinstalled by reversing the process
3Ease of operation
If a locking structure with multiple components is implemented, then ease of assembly and disassembly is improved, but device complexity increases
Solution Approach 1:
Multiple locking members are combined within a single roller assembly, and the switch member integrates the control function for all locking members. The locking members work together through coordinated movement along guide grooves, reducing the need for separate control mechanisms for each locking point and simplifying the overall structure

AI summary
An enteral feeding pump includes a pump main body, a roller assembly. The roller assembly includes a housing and a locking structure connected to the housing. The locking structure includes a switch member and a cooperating locking member. The roller assembly is detachably connected to the pump main body, and the locking member is configured to be in an unlocked position or a locked position depending on when the switch member is triggered. The roller assembly is thereby easy to assemble and disassemble for cleaning and maintenance.
