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
1Reliability
If traditional hose brackets are used to secure pump hoses, then the hoses can be positioned along the pumping path, but the hoses experience frequent wear and require frequent replacement due to lack of effective securing mechanisms
Solution Approach 1:
The hose bracket is divided into an outer bracket and an inner bracket that work together. The outer bracket provides the securing structure while the inner bracket engages with the hose coupling, distributing wear and improving retention. This segmentation allows each component to be optimized for its specific function, reducing overall hose wear.
Solution Approach 2:
The hose coupling is designed with features that preliminarily position and secure the hose before the pump operates. The bracket structure pre-positions the hose along the pumping path, ensuring proper alignment and reducing movement-induced wear during operation.
2Reliability
If manual or specialized equipment is used for hose installation and locking, then secure positioning can be achieved, but installation time and complexity increase
Solution Approach 1:
The hose bracket system is designed to be self-installing without requiring manual or specialized equipment. The inner bracket engages with the hose coupling and the outer bracket through inherent mechanical interference features, allowing the hose to secure itself automatically when installed, eliminating the need for additional tools or complex procedures.
Solution Approach 2:
The inner bracket acts as an intermediary between the hose coupling and the outer bracket. It facilitates the connection by providing engagement surfaces that automatically align and secure the hose, simplifying the installation process while maintaining secure positioning.
3Ease of operation
If the hose bracket uses a simple design without additional securing mechanisms, then ease of installation is improved, but the hose may disengage from the bracket
Solution Approach 1:
The inner bracket is nested within the outer bracket structure. The inner bracket engages with the hose coupling while the outer bracket provides the external securing structure. This nested arrangement maintains installation simplicity while adding multiple retention points that prevent hose disengagement.
Solution Approach 2:
The hose bracket system combines two distinct bracket components (inner and outer) made of rigid materials that work together. The composite structure of nested brackets provides enhanced retention capability while maintaining the simplicity of a single-piece installation process.

Function Achieved in This Case
Facilitates quick and tool-free installation and removal of the pump hose, reducing wear and tear, and extending the lifespan of the hose by securely positioning it for efficient operation with rollers.
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.
