Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-part sealing assembly is used to fulfill multiple sealing functions, then the sealing functions (fire protection, acoustic insulation, moisture sealing) are achieved, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent combines multiple sealing functions into a single integrated sealing element. The receiving space contains functional materials that provide fire protection, acoustic insulation, and moisture sealing simultaneously, eliminating the need for separate sealing components and simplifying the overall device structure.
Solution Approach 2:
The sealing element is designed with multi-functionality by incorporating a receiving space that can contain various functional materials. This single element can perform multiple sealing functions (fire protection, acoustic insulation, moisture sealing) depending on the material selected, making it a universal solution for different sealing requirements.
2Adaptability or versatility
If a multi-part sealing assembly is used to fulfill multiple sealing functions, then the sealing functions are achieved, but the ease of manufacture decreases
Solution Approach 1:
The patent merges multiple sealing functions into a single manufacturable component. The receiving space is integrated into the sealing element structure, allowing functional materials to be contained within a single piece that can be manufactured as one unit, significantly improving ease of manufacture compared to assembling multiple separate components.
3Adaptability or versatility
If essentially formless sealants or sealing pastes are introduced into the building joint, then various sealing functions can be provided, but the ease of operation decreases and installation becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-forming the sealing element with a specific geometry including a receiving space before installation. The functional materials are contained within this pre-formed structure, eliminating the need for complex application processes required for formless sealants or pastes, and allowing simple insertion into the building joint.
4Adaptability or versatility
If the support layers converge in a V-shape to provide flexibility and adapt to relative movements, then the adaptability to joint width variations is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes parameter changes by allowing the support layers to converge at specific angles forming a V-shape. This geometric parameter enables the sealing element to adapt to relative movements and joint width variations while maintaining manufacturability, as the V-shape can be produced using standard manufacturing processes with controlled angular parameters.

AI summary
The invention relates to a sealing element (10) for a construction joint, the sealing element comprising a first carrier layer (12) and a second carrier layer (14). In a cross-sectional view (A) oriented perpendicularly to a longitudinal direction (L) of the sealing element (10), the two carrier layers (12, 14) are essentially of equal length, and at least one portion of the first carrier layer (12) and at least one portion of the second carrier layer (14) run towards each other in a V shape. Furthermore, an accommodating space (18) is formed between the first carrier layer (12) and the second carrier layer (14), in which accommodating space a functional material (20) is accommodated.
