Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing radiator systems with multiple heating elements face challenges in adjusting flow distribution asymmetrically after installation, leading to uneven heating, and lack a mechanism to prevent unauthorized rotation of control valves.

Innovation Solution

A device with a pressure nut mechanism that allows selective adjustment of the valve body's angular position within the valve housing, enabling asymmetrical or symmetrical flow distribution between heating elements, and includes peripheral seals and attachments to control fluid flow, preventing unauthorized rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the valve body is made rotatable to enable flow distribution adjustment between heating elements, then the adaptability of the device is improved, but the reliability deteriorates due to unauthorized rotation

Engineering Contradiction:

Improveflow distribution adjustmentVSAvoidunauthorized rotation prevention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The valve body is designed to be rotatable within the valve housing, allowing dynamic adjustment of flow distribution between heating elements. The pressure nut mechanism enables the valve body to be fixed at selected angular positions while maintaining the ability to rotate for reconfiguration, thus achieving both adaptability and reliability.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the valve body is fixed in position to prevent unauthorized rotation, then the reliability is improved, but the ease of operation deteriorates due to inability to adjust flow distribution

Engineering Contradiction:

Improveunauthorized rotation preventionVSAvoidflow distribution adjustment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

3Reliability

If a pressure nut mechanism is added to fix the valve body in angular positions, then the reliability is improved by preventing unauthorized rotation, but the device complexity increases

Engineering Contradiction:

Improveunauthorized rotation preventionVSAvoidpressure nut mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The pressure nut mechanism is designed to be self-contained and self-operating. Once the valve body is rotated to the desired angular position, the pressure nut automatically engages with the valve body's peripheral area to secure it in place, preventing unauthorized rotation without requiring additional complex locking mechanisms or external components.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If the valve body is made adjustable to enable asymmetrical flow distribution, then the adaptability is improved, but the manufacturing precision requirements worsen due to angular position alignment

Engineering Contradiction:

AI summary

The invention relates to a device for selectively symmetrically or asymmetrically supplying heating fluid to at least two heating elements (20) connected to the device for fluid conduction, optionally heating plates, the device having a valve housing (1) with two valve housings (1) in different, optionally opposite directions, outgoing fluid connections (2, 2') and a valve (40) which can be inserted into a valve seat (3) of the valve housing (1) and has a valve body (6) having a fluid inlet (4) and a fluid outlet (5). According to the invention, the valve body (6) with the fluid outlet (5) can be inserted into the valve housing (1) in at least two different angular positions around the longitudinal axis (A) of the valve receptacle (3) by rotating it about its longitudinal axis (L). and can be fixed if necessary, and - depending on the selected angular position, the heating fluid flows from the fluid outlet (5) to the fluid connection (2, 2') of the valve housing (1) assigned to this angular position or simultaneously to both fluid connections (2, 2') outflowable.
