Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow rate regulators for heating systems are not compact enough and have complex structures, making them difficult to integrate into existing heating systems and prone to incorrect operation.
Innovation Solution
Inverting the kinematics of the components by making the formerly stationary cone movable and the pot stationary, with a rotary handle actuation, and using a guide element and guide groove to convert rotational movement into precise longitudinal movement, along with a self-locking mechanism and a transmission member with a non-circular cross-section for precise control, and incorporating a sieve for foreign matter protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the conventional flow rate regulator design is used with a stationary pot and displaceable cone, then the flow rate can be preset precisely, but the structure becomes complex and the space requirement is large
Solution Approach 1:
The patent inverts the conventional arrangement by making the pot displaceable and the cone stationary. The handle is connected to the pot via a transmission element with a non-circular cross-section that converts rotational movement into longitudinal displacement of the pot. This inversion maintains precise flow rate control while simplifying the overall structure and reducing space requirements.
2Ease of operation
If the conventional flow rate regulator design is used, then the flow rate can be regulated dynamically, but the device occupies too much space for standardized housing integration
Solution Approach 1:
By inverting the arrangement to have a stationary cone and displaceable pot, the patent achieves compact dimensions that allow integration into standardized housing while maintaining dynamic flow rate regulation capability through the handle actuation mechanism.
Solution Approach 2:
The transmission element with non-circular cross-section is nested within the handle assembly, and the displacement section engages with the cone's recess, creating a compact nested structure that minimizes space occupation while preserving full functionality.
3Ease of operation
If the pot is made displaceable to enable flow rate control, then the flow can be regulated, but the structure becomes more complex
Solution Approach 1:
The patent simplifies the structure by inverting the arrangement: the pot becomes displaceable (simpler connection to handle), while the cone remains stationary (simpler mounting). The transmission element directly couples the handle's rotational movement to the pot's longitudinal displacement, creating a straightforward mechanical linkage.
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 design results in a more compact structure, easier integration into heating systems, precise flow rate control, and protection against maladjustment and contamination, while maintaining familiar rotary actuation for users.
Implementation Method 1
The cone has a guide element for converting the rotary movement of the handle into a longitudinal movement, which engages in a correspondingly designed guide groove of the volume control module
Implementation Method 2
The sleeve, which is braced against the pot by means of a spring, is displaced as a result of the changed pressure conditions in such a way that its free cross-section of the first flow opening for the heating medium is adjusted to the flow situation
Implementation Method 3
A pressure difference, which occurs across the second flow opening formed between the cone and the recess provided on the pot, changes with the flow rate. The sleeve, which is braced against the pot by means of a spring, is displaced as a result of the changed pressure conditions
