Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributor valves with flow meters for hot water systems require precise regulation of flow rates, which is challenging due to imprecise setting mechanisms and potential unintentional adjustments, leading to inefficiencies and power losses.
Innovation Solution
A distributor valve with a presetting device that includes a stroke limiter controlled by an axial movable adjusting member and a securing element, allowing for reproducible setting of the valve body position, ensuring precise and consistent flow rate regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual drive with adjustable sleeves is used for setting end positions, then the valve can be adjusted to different positions, but the setting is imprecise and the sleeves can move unintentionally during operation
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated drive mechanism. The automated drive eliminates the need for manual positioning and adjustable sleeves, providing precise and reproducible valve positioning through automated control, thereby resolving the contradiction between ease of operation and setting precision.
Solution Approach 2:
The automated drive system performs the positioning function autonomously without requiring manual intervention. The system self-regulates the valve position through automated control mechanisms, eliminating the imprecision and unintentional movement issues associated with manual adjustable sleeves while maintaining operational ease.
2Adaptability or versatility
If manual adjustment of valve position is used, then the operator can set different flow rates, but the setting requires tact and responsibility and is not reproducible
Solution Approach 1:
The patent replaces manual adjustment mechanisms with an automated drive system that provides reproducible positioning. The automated system uses controlled mechanisms to achieve consistent valve positions for different flow rates, eliminating the need for operator tact and responsibility while ensuring reliable reproducibility of settings.
Solution Approach 2:
The automated drive system incorporates feedback mechanisms to ensure accurate and reproducible valve positioning. The system monitors and adjusts the valve position based on predetermined parameters, ensuring that the same flow rate settings can be consistently reproduced without relying on operator skill or attention.
3Ease of operation
If axially adjustable sleeves with stops are used for limiting stroke, then end positions can be set, but the sleeves can move during hand wheel actuation causing unintentional adjustment
Solution Approach 1:
The patent replaces the mechanical sleeve-based stroke limitation system with an automated drive mechanism. The automated system provides stable and secure stroke limitation through controlled actuation, eliminating the movement and instability issues of adjustable sleeves during operation while maintaining ease of stroke limitation.
