Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The operation of almost floor-to-ceiling panel radiators with control valves attached to the top is inconvenient, as it complicates the installation and usage of these radiators with large heating surfaces, especially at low heating medium temperatures.

Innovation Solution

The valve carrier is relocated below the heating medium pipe, allowing for ergonomic placement and minimizing tooling and storage costs by using existing components, with a ventilation element controlling the flow between the front and rear heating panels, and an optional direct connection to the rear heating panel for simplified installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If control valves are attached to the top of the radiator, then the heating output is sufficient, but the operation becomes inconvenient and installation is complicated

Engineering Contradiction:

Improveheating outputVSAvoidoperation convenience

Core Design Contradiction:

PowerVSEase of operation

Solution Approach 1:

The valve carrier is inverted from its conventional top-mounted position to a bottom-mounted position on the radiator. This inversion allows the control valve to be operated from below at an ergonomic height, resolving the operational inconvenience while maintaining the heating performance through the serial flow configuration between front and rear heating panels.

Principle #13The other way round (Inversion)

2Area of stationary object

If control valves are attached to the top of the radiator, then the heating surface is effectively utilized, but the installation becomes complicated

Engineering Contradiction:

Improveheating surfaceVSAvoidinstallation complexity

Core Design Contradiction:

Area of stationary objectVSEase of manufacture

Solution Approach 1:

By inverting the valve carrier position from top to bottom, the installation process is simplified as the valve carrier can be mounted from below without requiring complex overhead support structures. The bottom mounting position allows for easier access during installation while preserving the full heating surface area through the serial flow design.

Principle #13The other way round (Inversion)

3Ease of operation

If a separate valve carrier is introduced, then the valve connection can be relocated, but the device complexity increases

Engineering Contradiction:

Improvevalve accessibilityVSAvoidcomponent quantity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The valve carrier is designed as a multi-functional component that serves both as a mounting support for the control valve and as part of the heating medium flow path. It includes integrated features such as the inlet opening, outlet opening, and venting element, allowing it to perform multiple functions without requiring additional separate components, thus minimizing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The panel radiator (1) has a valve carrier (13) below a heating tube (7) provided with a valve port (14), where the heat of a front heater plate (2) flows through the valve carrier into a rear heater plate (3) in a heating mode. A flow connection (25) is provided at a bottom (5) of the panel radiator for connecting the front heater plate to a bottom-side heating-medium flow. The flow of the heating medium is blocked through the heating tube from the front heater plate to the rear heater plate, where the front heater plate is provided with two half-shells.
