Pull-Out Hose Guide Weight Roller Blocking for Maintenance Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out hose guiding devices lack effective mechanisms to prevent guide weight rollers from moving undesirably during maintenance, tilting, or fluid emptying, leading to potential damage or interference.
Innovation Solution
A roller blocking device that holds guide weight rollers in place by blocking further movement beyond a defined position, using a combination of a blocking bracket, pivot lever, or rotatable threaded control rod to secure the rollers within the hose guiding box, preventing them from falling or moving excessively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guide weight rollers are allowed to move freely during maintenance, tilting, or fluid emptying, then ease of operation is improved, but reliability deteriorates as rollers may move undesirably causing damage or interference
Solution Approach 1:
The blocking bracket is designed to be movable between a blocking position and a release position. During normal operation, the bracket is in the release position allowing free movement of guide weight rollers. During maintenance or tilting operations, the bracket moves to the blocking position to prevent roller movement, thus resolving the contradiction between ease of operation and reliability
Solution Approach 2:
The pivot lever mechanism allows the blocking bracket to be easily positioned by the user through simple manual operation. The system serves itself by allowing the user to engage or disengage the blocking function as needed, without requiring complex control systems, thereby maintaining ease of operation while improving reliability
2Reliability
If guide weight rollers are blocked during normal operation, then reliability is improved by preventing damage, but ease of operation deteriorates as rollers cannot move freely
Solution Approach 1:
The blocking bracket is designed to be movable between a blocking position and a release position. During normal operation, the bracket is in the release position allowing free movement of guide weight rollers. During maintenance or tilting operations, the bracket moves to the blocking position to prevent roller movement, thus resolving the contradiction between ease of operation and reliability
Solution Approach 2:
The system allows preliminary engagement of the blocking function before maintenance or tilting operations begin. By preparing the blocking bracket in advance, the system ensures reliability is improved without affecting normal operation, as the blocking mechanism is only activated when needed
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
Ensures the guide weight rollers remain securely positioned, preventing damage and interference during maintenance, tilting, or fluid emptying, while allowing free movement during normal hose operation.
Implementation Method 1
the guide weight roller forms a loose roller which can guide the hose bend in the bend reversal region and, by way of its weight, can stabilize the hose bend overall

AI summary
A pull-out hose guiding device for guiding a pull-out hose having at least one hose bend of variable hose bend length, wherein the pull-out hose guiding device includes a hose guiding box configured for accommodating the hose bend in an anti-twist manner in a box-inwards hanging position, and a guide weight roller arrangement including at least one guide weight roller which is insertable into a bend reversion zone of the hose bend for rotary motion about a roller rotational axis. The guide weight roller with its roller rotational axis is capable of translational motion in a hose bend lengthwise direction box-outwards with decreasing hose bend length and box-inwards with increasing hose bend length. A sanitary shower device may be equipped with such a pull-out hose guiding device.
