Heating/cooling system pre-setting arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pre-setting arrangements for heating/cooling systems are cumbersome to adjust, requiring frequent rotation of the setting ring to adjust multiple circuits, which can disrupt flow conditions and is inefficient for installers.
Innovation Solution
The introduction of holding means that keep the setting ring in a position where it cannot engage with the housing geometry, allowing for simultaneous adjustment of multiple circuits without returning to the engaging position until all are completed, using axial and radial spring elements, snap connections, and friction surfaces to secure the ring in a rotatable position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the setting ring is made rotatable for adjusting pre-setting, then the pre-setting can be changed, but the setting ring may be accidentally rotated during installation of multiple circuits
Solution Approach 1:
The setting ring is designed to be dynamically switchable between two states: locked (non-rotatable) during normal operation and unlocked (rotatable) during adjustment. The locking mechanism allows the ring to be held firmly in position once set, preventing accidental rotation, while still permitting intentional rotation when needed for re-adjustment.
2Measurement precision
If the installer repeatedly engages and disengages the setting ring for each circuit adjustment, then each circuit can be precisely adjusted, but the installation process becomes time-consuming and cumbersome
Solution Approach 1:
The setting ring is designed to be preliminarily positioned and locked before the actual pre-setting adjustment begins. This allows the installer to set the ring once at the beginning and maintain it in that position throughout the adjustment of multiple circuits, eliminating the need to repeatedly engage and disengage the ring for each circuit.
3Productivity
If the setting ring is held in a fixed position using holding means, then the installer can work on multiple circuits efficiently, but the setting ring cannot be re-adjusted if needed
Solution Approach 1:
The holding means are designed to be temporary and releasable, not permanent. The setting ring can be held in position during installation for efficiency, but can be released and re-positioned if re-adjustment is needed later, providing both productivity and adaptability.
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
This solution simplifies the pre-setting process by allowing the installer to perform adjustments on multiple circuits without re-engaging the ring until all are finished, reducing the need for repeated manipulation and enhancing comfort and efficiency.
Implementation Method 1
the spring element can be deformed in radial direction and holds the setting ring in position when it returns to its initial position
Implementation Method 2
friction surfaces at the setting ring and at the housing producing a friction force

AI summary
A heating/cooling system pre-setting arrangement (1) is provided, the pre-setting arrangement (1) comprising a housing (2) and presetting means (11, 12) defining a maximum flow through the valve arrangement (1) at a given pressure, wherein the presetting means comprise a presetting element (11) actuatable by means of a setting ring (6), wherein the setting ring (6) comprises a first geometry (7) and the housing (2) comprises a second geometry (8), the first geometry (7) and the second geometry (8) preventing rotation of the setting ring (6) when they are in engagement. Actuation of such a presetting arrangement (1) should be comfortable. To this end holding means (14, 15) are provided holding the setting ring (6) in a position in which the first geometry (7) is out of engagement of the second geometry (8).
