Solution Overview

Problem

Existing radiators have limited flexibility in configuring convector channels, leading to unnecessary weight and production costs due to a fixed number of convector channels determined by the shape of the convector sheet, which does not allow for optimal heating power adjustment.

Innovation Solution

The radiator design features convector sheets with a Z-shape, including a single level base and stiffening sections that extend from the base to the thigh, allowing for adjustable positioning and varying densities of convector sheets along the heating channels, enabling optimal heat exchange and reduced material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If convector sheets are used with a fixed shape to form convector channels, then the structure is simple and easy to manufacture, but the number of convector channels is fixed and cannot be adjusted, leading to unnecessary weight and production costs

Engineering Contradiction:
Improveease of manufactureVSAvoidflexibility in configuring convector channels
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The convector sheet is divided into multiple individual convector plates that can be independently arranged and connected to heating channels. Each convector plate is a separate component that can be selectively positioned along the heating channel, allowing flexible configuration of the number and density of convector channels without requiring a completely different sheet design for each configuration.

Inventive Principle:
Principle #1Segmentation

2Power

If the number of convector channels is increased to provide optimal heating power, then the heating performance is improved, but the weight and production costs increase due to more material usage

Engineering Contradiction:
Improveheating powerVSAvoidweight
Core Design Contradiction:
PowerVSWeight of stationary object

Solution Approach 1:

Individual convector plates can be selectively positioned and distributed at varying densities along the heating channel based on local heating requirements. Areas requiring higher heating power can have more closely spaced convector plates, while areas needing less heating can have more sparse spacing, optimizing the distribution of material and weight according to actual thermal demands.

Inventive Principle:
Principle #3Local quality

3Weight of stationary object

If convector plates are made thin to reduce weight, then the material usage is minimized, but the stability and structural integrity of the convector plates deteriorates

Engineering Contradiction:
ImproveweightVSAvoidstability
Core Design Contradiction:
Weight of stationary objectVSStability of the object's composition

Solution Approach 1:

The convector plate consists of a base made from sheet material and legs made from profiled material (such as U-shaped or C-shaped profiles). This composite structure combines the thin, lightweight base with the structurally stronger profiled legs, creating a component that achieves both reduced weight and improved stability. The profiled legs provide enhanced rigidity and mechanical strength while adding minimal weight compared to a fully thick construction.
