Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing profiles with complex structures are produced using traditional extrusion and assembly processes, then the sealing profiles provide reliable sealing and fastening functions, but the manufacturing process becomes complex and inefficient
Solution Approach 1:
The patent combines multiple sealing profiles into a single multi-layer web structure. The base bodies from the first web and fastening sections from the second web are joined together through adhesive strips to form an integrated composite structure, eliminating the need for separate extrusion and assembly processes while maintaining reliable sealing and fastening functions
Solution Approach 2:
The patent uses composite material structure by combining two different webs (first web with base bodies and second web with fastening sections) into a single multi-layer web. This composite approach allows different parts of the sealing profile to be made from materials optimized for their specific functions while simplifying the overall manufacturing process
2Productivity
If adhesive strips are applied close to each other to maximize material usage, then production efficiency increases, but the structural integrity and sealing effectiveness of individual profiles deteriorate
Solution Approach 1:
The patent applies adhesive strips at specific locations on the webs rather than uniformly across the entire surface. The adhesive strips are positioned to connect base bodies to fastening sections while leaving other areas free to provide structural integrity and sealing effectiveness, achieving both production efficiency and reliable sealing
Solution Approach 2:
The patent segments the adhesive application into discrete strips rather than continuous coverage. This segmentation allows the adhesive strips to provide necessary bonding while leaving gaps that maintain the structural independence and sealing capability of each sealing profile

AI summary
The invention relates to a method for producing multiple profiled seal sections (20) for an edge joint of a drywall, having the following steps: a) providing a first web (62) made of a sealing material, b) applying multiple adhesive strips (36) onto the first web (62), wherein adjacent adhesive strips (36) are arranged at a distance to one another, said distance corresponding to at least 50% of the height (B) of a profiled seal section (20), c) providing a second web (64), d) bringing together and connecting the first web (62) and the second web (64) via the adhesive strips (36) in order to form a multilayer web (66), and e) introducing multiple cuts (68) in a special manner at a distance to all of the adhesive strips (36) in order to form a number of profiled seal sections (20). The invention additionally relates to a profiled seal section (20) produced in this manner.
