Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-part seal structures are used to provide multiple functions (fire protection, acoustic insulation, sealing), then the sealing functions are fulfilled, but the device complexity increases and installation becomes more difficult
Solution Approach 1:
The patent combines multiple sealing functions (fire protection, acoustic insulation, moisture sealing) into a single integrated sealing element. The carrier layers are formed as one piece with continuous surfaces, eliminating the need for multiple separate components and simplifying both the structure and installation process while maintaining all required sealing functions.
Solution Approach 2:
The sealing element is designed to perform multiple functions simultaneously through its single structure. The carrier layers provide structural support and sealing, while the receiving space accommodates functional materials for fire protection and acoustic insulation, making the element universal for various sealing requirements in structural joints.
2Reliability
If multi-part seal structures are used to provide multiple functions, then the sealing functions are fulfilled, but the ease of installation deteriorates
Solution Approach 1:
By merging all sealing functions into a single pre-fabricated element with continuous carrier layers, the patent eliminates the need for complex assembly operations on-site. The element can be installed as one piece, significantly improving installation ease while maintaining reliable sealing performance.
3Ease of operation
If prefabricated sealing elements are used, then the ease of installation is improved, but the adaptability to varying joint widths deteriorates
Solution Approach 1:
The carrier layers are designed with portions that extend toward each other in a V-shape, creating a dynamic structure that can adapt to different joint widths. This geometric configuration allows the element to flex and adjust its shape to accommodate variations in structural joint dimensions while maintaining sealing effectiveness.
4Ease of manufacture
If simple structure is used for the sealing element, then the ease of manufacture and cost are improved, but the ability to provide multiple sealing functions deteriorates
Solution Approach 1:
The sealing element is segmented into distinct functional zones within the single structure: carrier layers for structural support and sealing, and a receiving space for functional materials. This segmentation allows each part to be optimized for its specific function while maintaining overall manufacturing simplicity and cost-effectiveness.
Solution Approach 2:
The simple single-piece structure achieves multi-functionality by integrating carrier layers that provide structural support and sealing, while the receiving space between them accommodates functional materials for fire protection and acoustic insulation, all within one manufacturable element.

AI summary
A sealing element for a structural joint contains a first carrier layer and a second carrier layer. The two carrier layers, in a cross-sectional view oriented perpendicularly to a longitudinal direction of the sealing element, are substantially the same length. At least one portion of the first carrier layer and at least one portion of the second carrier layer extend toward one another in a V shape. A receiving space, in which a functional material is received, is also formed between the first carrier layer and the second carrier layer.
