Panel Radiator Cladding With Rounded Groove Edge Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cladding panel radiators with steel sheets result in incomplete formation of grooves due to manufacturing inaccuracies, leading to visually unfavorable and potentially hazardous sharp edges, as well as material weakness.
Innovation Solution
Removing a partial volume in the rounding area of the steel sheet to create a defined edge, either by punching or thinning, allowing the material to flow and form a continuous groove edge, with optional circular or segmented punching and strategic arrangement of openings to enhance uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If tongues are created in the curve by removing partial volumes of the steel sheet, then the groove edge should be formed, but manufacturing inaccuracies cause the tongues to incompletely abut, resulting in sharp edges and material weakness
Solution Approach 1:
The patent applies preliminary action by pre-forming a groove in the steel sheet before folding. This groove is created by removing a partial volume of material in advance, which guides the material flow during folding and ensures continuous groove edge formation without relying on precise tongue abutment. The groove is formed by punching or thinning the steel sheet in the corner area before the folding operation
Solution Approach 2:
The patent changes the physical state and geometry of the steel sheet by removing a partial volume of material in the corner area. This parameter change creates a groove with specific dimensions (depth and width) that allows the material to flow continuously during folding, transforming the corner area from a potential sharp edge into a smooth, continuous groove edge
2Ease of manufacture
If the steel sheet is folded over to form a groove, then the panel radiator is covered, but incomplete groove formation creates visually unfavorable and hazardous sharp edges
Solution Approach 1:
The groove is formed in advance by removing material before folding, which simplifies the folding process and eliminates the need for precise tongue alignment. This preliminary groove formation makes the manufacturing process more robust against variations while eliminating sharp edges
3Shape
If tongues are created to form the groove edge, then the groove should be defined, but the tongues protrude individually creating visual defects and safety hazards
Solution Approach 1:
The patent extracts or removes a partial volume of material from the corner area to create a continuous groove. By removing material rather than relying on protruding tongues, the solution achieves continuous groove edge formation and eliminates the harmful protruding tongues that create visual defects and safety hazards
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
The solution ensures a smooth, uniform groove formation along the curve, eliminating sharp edges and material weaknesses, resulting in a safer and more aesthetically pleasing product.
Implementation Method 1
When folded over, the material of the steel sheet flows into the areas created by removing the partial volume
Implementation Method 2
the panel radiator being bonded to the steel sheet

AI summary
The method involves cutting an edge (5) of a steel sheet (1) in a corner region (3) of the steel sheet into a rounded portion (4). A partial volume of the steel sheet in the rounded portion is removed. The edge along the rounded portion is turned over to an open groove. The plate heater is covered with the steel sheet. Another edge is formed on the steel sheet while removing partial volume of the steel sheet in the rounded portion. The rounded portion is formed around spacing in relation to a straight region, which is located in an inner area of steel sheet.
