Lamella element and method for producing a lamella element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamellar elements for heating devices, such as those used in motor vehicles and air conditioning systems, require additional components like radiator sheets or soldering for fixation, which increases production costs and complexity.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional components like radiator sheets or soldering are used for fixation, then the rigidity and stability of the lamellar element are improved, but the production cost and device complexity increase
Solution Approach 1:
The connecting sections are integrated directly into the lamellar element structure, merging the function of connection and rigidity reinforcement into a single component. This eliminates the need for separate radiator sheets or soldering operations, reducing both device complexity and production cost while maintaining structural strength.
Solution Approach 2:
The connecting sections are designed to automatically provide rigidity reinforcement through their own geometric configuration and material properties. The structure serves itself by incorporating stiffening features directly into the connecting sections, eliminating the need for external reinforcement components or additional processing steps like soldering.
2Strength
If the entire connecting section is plastically deformed to increase rigidity, then the rigidity of the lamellar element is significantly improved, but the manufacturing complexity and production cost increase
Solution Approach 1:
Instead of deforming the entire connecting section, plastic deformation is applied only to specific local areas that are most critical for providing rigidity. This selective deformation approach maintains the necessary structural strength while significantly reducing the complexity and cost of the manufacturing process compared to full-section deformation.
Solution Approach 2:
The invention applies partial deformation to the connecting sections, deforming only the portions necessary to achieve the required rigidity level. This partial action is sufficient to solve the technical problem without the excessive complexity and cost associated with deforming the entire connecting section.

AI summary
A lamellar element is disclosed which has lamellae which are connected to one another in one piece via connecting sections. In order to increase rigidity, the lamellar element is subjected to a pressing force during manufacture from its connecting sections approximately in the direction of the lamellae, with the result that at least the connecting sections are plastically deformed. Additionally or alternatively, beads are incorporated in some or all of the lamellae.
