Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding or screwing tools are used to fix metallic components, then connection strength is improved, but device complexity and production time increase
Solution Approach 1:
The mounting device enables self-service fastening through the interaction between projecting fastening elements and receiving structures. The components can be assembled without external welding or screwing tools, as the mounting device itself provides the fastening function through its geometric design of projecting elements that engage with corresponding receiving structures on the workpiece.
Solution Approach 2:
The mounting device separates the fastening function from the base structure by incorporating distinct projecting fastening elements. These elements are segmented from the base plate and designed to independently engage with receiving structures, allowing the fastening function to be achieved without complex external tools while maintaining connection strength.
2Ease of operation
If plastic hook-and-loop closures are used for fastening, then ease of operation is improved, but reliability and temperature stability deteriorate
Solution Approach 1:
The invention changes the material parameter from plastic to metal, fundamentally altering the temperature stability and durability characteristics. The metallic mounting device maintains ease of operation through its geometric fastening design while achieving superior temperature stability and reliability through the inherent properties of metal materials, which can withstand higher temperatures and greater mechanical loads compared to plastic alternatives.
3Manufacturing precision
If electrode beam method is used to structure surface, then connection precision is improved, but manufacturing time and complexity increase
Solution Approach 1:
The mounting device incorporates pre-formed projecting fastening elements that are manufactured in advance with precise geometries. These elements are prepared beforehand through conventional manufacturing processes and then attached to the base plate, eliminating the need for time-consuming electrode beam processing during final assembly while maintaining the required precision through the pre-manufactured geometric features.
4Ease of manufacture
If multiple fastening elements are incised and bent into base plate, then ease of manufacture is improved, but structural complexity increases
Solution Approach 1:
The invention replaces complex external fastening systems (welding, screwing) with a simplified mechanical interlocking system. The projecting fastening elements with specific geometries engage directly with receiving structures through basic mechanical insertion, eliminating the need for complex external tools and processes while achieving secure connections through the inherent geometric design of the interlocking features.

AI summary
The present invention thus relates to a mounting device having a metallic base plate, on which multiple fastening elements are provided, from each of which at least a partial area projects above the base plate. The mounting device is obtainable by incising fastening element blanks into the surface of the metallic base plate while leaving one connection edge per blank in such a way that they each have a web-shaped base area, which comprises the connection edge on one end, and a head area adjoining the base area, which projects laterally beyond the neighboring base area on at least one side. At least one partial area of the blanks is bent out of the base plate around at least one bending edge located in the base area. The projecting edge of the head area adjoining the base area runs at an angle between 0° and 70° in relation to the plane of the base plate after the fastening elements are bent out of the base plate. In addition, the present invention relates to a method for producing this mounting device.
