Flexible fluid connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating distributors in hydronic systems face challenges with limited tube extension due to sinus-shaped walls and difficulty in installation in tight spaces, leading to potential recirculation of treated fluid.
Innovation Solution
A flexible fluid connector with a long, flexible elongate tube that can bend and extend further into the distributor's inner space, allowing easier installation and reducing recirculation by providing a longer path for fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a rigid tube is used to prevent recirculation of treated fluid, then the tube can extend into the inner space of the housing, but the tube length is restricted by the sinus shaped wall and it is difficult to install in tight spaces
Solution Approach 1:
The patent applies this principle by replacing the rigid tube with a flexible tube that can bend and conform to the sinus-shaped wall geometry. The flexible tube can extend further into the inner space without being constrained by the rigid structure, while also being able to navigate tight installation spaces through its flexibility. This resolves the contradiction by allowing both extended length and ease of installation.
Solution Approach 2:
The patent applies this principle by making the tube flexible rather than rigid, allowing it to dynamically adapt its shape during installation and operation. The flexible tube can be maneuvered into position during installation and will naturally conform to the optimal path for preventing recirculation, combining installation ease with effective recirculation prevention.
2Reliability
If the tube is made longer to prevent recirculation, then treated fluid will not recirculate, but the tube becomes more difficult to install in tight spaces
Solution Approach 1:
The flexible tube allows the system to achieve both long effective length for recirculation prevention and ease of installation. The tube can be bent and routed through tight spaces during installation, then extended to the necessary length to prevent recirculation by reaching deep into the inner space without requiring rigid structural support.
