Fluid Line Guide Assembly for Precise Valve Insertion Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in manufacturing appliances like refrigerators is accurately installing fluid lines into fluid valves, especially when components are obstructed or difficult to access, leading to potential improper installation, impeded fluid flow, and leaks.
Innovation Solution
A fluid line insertion guide with a collet and biasing mechanism that includes a retaining channel and biasing surface, allowing for precise alignment and final insertion depth without direct visibility of the valve components, using a collet with a biased end and insertion end, and a fluid line guide with a flange and biasing surface to ensure proper communication between the fluid line and valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual installation methods are used for fluid lines in obstructed areas, then installation flexibility is maintained, but installation precision and reliability deteriorate
Solution Approach 1:
The guide assembly acts as an intermediary tool between the installer and the fluid line/valve interface. It provides predetermined positioning features that guide the fluid line to the correct insertion depth without requiring complex measurement or alignment procedures by the installer.
Solution Approach 2:
The guide assembly is pre-configured with positioning features, channels, and alignment elements before installation. This preliminary preparation ensures that when the fluid line is installed, it automatically achieves the correct depth and orientation without requiring complex real-time adjustments.
2Reliability
If visual inspection is used to verify installation, then installation accuracy can be monitored, but installation time increases due to difficulty accessing obstructed components
Solution Approach 1:
The guide assembly incorporates self-verifying features such as alignment indicators, positioning channels, and mechanical stops that automatically confirm correct installation without requiring external visual inspection or measurement by the installer.
Solution Approach 2:
The guide assembly may incorporate visual indicators (such as colored markings or transparent sections) that change or become visible when the fluid line is correctly positioned, providing immediate feedback without requiring close inspection of the obscured valve area.
3Manufacturing precision
If improper insertion depth occurs, then fluid flow may be impeded or leaks may occur, but preventing this requires complex positioning mechanisms
Solution Approach 1:
The guide assembly is divided into functional segments: a positioning channel that guides the fluid line, a biasing mechanism that applies force to achieve proper depth, and a retaining feature that holds the fluid line at the correct position. Each segment performs a specific function that collectively ensures precise insertion.
Solution Approach 2:
The guide assembly incorporates a biasing mechanism (such as a spring) that dynamically adjusts the positioning force applied to the fluid line. This dynamic adjustment ensures the fluid line is pushed to the correct depth while allowing for variations in manufacturing tolerances and installation conditions.

AI summary
A fluid line insertion guide for a refrigerator includes a collet adapted for engagement with a fluid line. The collet includes a biased end and an insertion end. The fluid line is inserted through a fluid line aperture defined within the biased end. The insertion end is configured to be inserted into a fluid valve to a final insertion depth to place the fluid line and fluid valve in communication with each other. A fluid line guide includes a retaining channel and a biasing surface. The retaining channel engages a valve housing to define a guide position. When the fluid line guide is in the guide position, the biasing surface is disposed a predetermined distance from a valve aperture of the fluid valve and further defines a position of the biased end of the collet and the final insertion depth of the insertion end into the fluid valve.
