Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction profiles for dry construction require longitudinal welding, which is environmentally harmful, energy-intensive, and results in corrosion protection needs, while offering limited torsional rigidity and buckling resistance.
Innovation Solution
The edges of the sheet metal are connected using a longitudinal pressed closure within longitudinal mounting embossed depressions, eliminating the need for welding and enhancing torsional rigidity and buckling resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If longitudinal welding is used to connect sheet metal edges, then the construction profile can be manufactured, but environmental harm increases, energy consumption increases, and corrosion protection is required
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a mechanical pressing system. The sheet metal edges are connected through longitudinal pressing that creates interlocking profiles without heat, eliminating toxic fumes, air filtration requirements, and corrosion protection needs while reducing energy consumption.
Solution Approach 2:
The patent changes the connection method from thermal welding to cold mechanical pressing. This parameter change eliminates the harmful effects of welding (toxic fumes, heat generation, energy consumption) while maintaining the structural integrity needed for construction profile manufacturing.
2Ease of manufacture
If longitudinal welding is used to connect sheet metal edges, then the construction profile can be manufactured, but corrosion protection needs increase economic and environmental burden
Solution Approach 1:
The patent replaces welding with mechanical pressing, which does not create weld areas susceptible to corrosion. The cold-forming process maintains the original material properties and surface integrity, eliminating the need for additional corrosion protection treatments and reducing economic and environmental burdens.
3Ease of manufacture
If conventional construction profile design is used, then manufacturing is simple, but torsional rigidity and buckling resistance are insufficient
Solution Approach 1:
The patent segments the sheet metal into multiple folded sections creating a complex three-dimensional cross-section with multiple planes and angles. This segmentation creates inherent geometric stiffness that resists torsion and buckling while maintaining manufacturability through sequential forming operations.
Solution Approach 2:
The patent transitions from a simple planar or single-dimensional profile to a multi-dimensional three-dimensional cross-section. The complex spatial geometry with multiple folded surfaces creates structural rigidity in multiple directions, simultaneously improving torsional rigidity and buckling resistance without complicating the manufacturing process.
4Strength
If sheet metal edges are connected by welding, then structural integrity is achieved, but heat generation negatively affects material characteristics
Solution Approach 1:
The patent replaces thermal welding with cold mechanical pressing, eliminating heat generation entirely. The mechanical pressing process achieves structural integrity through interlocking geometry and material deformation without thermal cycles, preserving the original material characteristics and avoiding heat-affected zones.
