Hose Bracket for Texture Sprayer Peristaltic Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peristaltic pump hoses experience frequent wear and require frequent replacement due to the lack of effective securing mechanisms in existing hose brackets, which often necessitate manual or specialized equipment for installation and locking.
Innovation Solution
A hose bracket system comprising a rigid outer and inner bracket assembly that utilizes the natural stiffness of the pump hose to retain the hose ends within central openings, allowing for easy installation and quick replacement without additional tools, by leveraging the hose's bias towards an unbent shape to secure it along the pumping path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hose brackets are used to secure pump hoses, then the hoses can be retained during operation, but the installation and replacement require manual labor or specialized equipment, reducing operational efficiency
Solution Approach 1:
The hose bracket system enables self-service installation and replacement. The spring-loaded roller mechanism automatically secures the hose when inserted, and the release lever allows single-person operation without external tools or assistance, making the hose replacement process self-sufficient and tool-free
Solution Approach 2:
The hose bracket incorporates a dynamic spring-loaded roller mechanism that adapts to the hose. The spring provides continuous pressure to retain the hose securely during operation, while allowing quick release when needed, enabling the system to transition between secure retention and easy release states
2Reliability
If pump hoses are frequently replaced due to wear, then operational reliability is maintained, but productivity is reduced due to repeated installation and removal operations
Solution Approach 1:
The hose bracket system prepares the hose retention mechanism in advance with pre-positioned rollers and spring pressure. The hose can be quickly inserted and immediately secured without requiring assembly or adjustment during replacement, enabling rapid hose changes while maintaining reliable hose securing throughout operation
3Reliability
If manual or specialized equipment is used to secure and replace hoses, then the hoses can be firmly retained, but the complexity of the installation process increases
Solution Approach 1:
The hose bracket system is designed for self-service operation where the spring-loaded roller mechanism automatically secures the hose upon insertion. The release lever provides a simple single-handed operation to remove the hose, eliminating the need for complex tools or multi-step procedures while maintaining firm hose retention during operation
Solution Approach 2:
The spring-loaded roller acts as an intermediary mechanism between the hose and the bracket structure. It provides the securing force through spring pressure while allowing the hose to be easily inserted and removed, simplifying the overall system while ensuring reliable hose retention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and tool-free installation and removal of the pump hose, reducing wear and tear, and simplifying the replacement process, thereby extending the hose's lifespan and improving operational efficiency.
Implementation Method 1
The pump hose has rigid hose ends connected by a bendable hose section with limited flexibility tending to bias the pump hose towards a substantially unbent shape

AI summary
A peristaltic pump comprises a drive assembly, a hose pump, and a hose bracket. The drive assembly is rotatably disposed within a frame to move a roller along a pumping path with respect to the frame. The pump hose has rigid hose ends connected by a bendable hose section with limited flexibility tending to bias the pump hose towards a substantially unbent shape. The hose bracket has a rigid body with a first central opening sized to receive the rigid hose ends at first and second retention locations, such that the natural bias of the pump hose towards a substantially unbent shape retains the hose ends within the first and second retention locations, positioning the bendable hose section along the pumping path of the roller.
