Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing tape is arranged under compression in the joint to ensure tight sealing against wind and driving rain, then the sealing performance is improved, but the weight increases
Solution Approach 1:
The sealing tape is divided into distinct functional zones: a compression zone with the sealing element arranged under compression for tight sealing, and a support zone with the carrier strip providing structural support. This segmentation allows the sealing function to be optimized independently from the weight-bearing function, maintaining effective sealing while minimizing overall weight.
Solution Approach 2:
Different regions of the sealing tape have different properties: the sealing element has high compression resistance and low permeability for wind and rain tightness, while the carrier strip has optimized strength-to-weight ratio. The plaster stripping edge provides localized plaster removal functionality. This local quality differentiation ensures each region performs its specific function efficiently without adding unnecessary weight elsewhere.
2Loss of energy
If the sealing tape provides best possible thermal insulation of the joint, then the thermal insulation performance is improved, but the weight increases
Solution Approach 1:
The sealing tape uses a composite structure combining a carrier strip (made from lightweight materials such as plastic or metal with optimized cross-section) and a sealing element (foam-based material with insulating properties). This composite design provides effective thermal insulation through the sealing element while the lightweight carrier strip minimizes overall weight, avoiding the need for heavy solid materials.
3Adaptability or versatility
If the sealing tape enables three-dimensional absorption of movement between components, then the adaptability to thermal expansion is improved, but the sealing reliability deteriorates
Solution Approach 1:
The sealing element is designed with dynamic properties to accommodate three-dimensional movements between components. The foam-based sealing element can deform elastically in multiple directions to absorb thermal expansion and contraction, while the carrier strip provides a stable anchor. This dynamic design maintains sealing reliability during movement by allowing the sealing element to adapt its shape while remaining connected to the stable carrier structure.
4Object-affected harmful factors
If the sealing tape allows water vapor diffusion from inside to outside the room, then the moisture management is improved, but the tightness against driving rain deteriorates
Solution Approach 1:
The sealing element has differentiated permeability properties: it is permeable to water vapor diffusion from the interior side to allow moisture escape, while the exterior side features a sealing lip or membrane that provides tightness against driving rain. This local quality differentiation allows simultaneous moisture management and weather protection by creating selective permeability at different locations of the sealing element.
5Stability of the object's composition
If the sealing tape prevents unintentional loosening during masonry insertion, then the stability is improved, but the weight increases
Solution Approach 1:
The carrier strip includes pre-integrated fastening elements such as adhesive layers or mechanical anchoring features that are prepared in advance for installation. These preliminary preparations enable the sealing tape to be securely fixed to the masonry opening and frame component during insertion, preventing unintentional loosening without requiring additional heavy fastening components to be added during installation.

Implementation Method 1
the sealing tape should allow a certain amount of water vapor diffusion from the inside of the room to the outside of the room in order to dissipate humidity from the inside of the room to the outside

AI summary
The invention relates to a sealing tape for sealing a joint between two components, in particular a joint of a reveal connection with a first component providing the reveal and a second component adjacent to the reveal, such as a frame component, wherein the sealing tape has a foam body with two opposing broad sides that can be applied to the two components in a sealing manner or facing these components and narrow sides connecting them, as well as with a plaster limiting device which projects from one narrow side of the foam body, wherein the narrowly projecting area of the plaster limiting device has a plastering edge which enables the application and removal of a plastering tool for plastering, preferably of the first component.According to the invention, the plaster limiting device is designed as a flexible plaster limiting strip and is surrounded on both sides by the foam body and arranged laterally spaced from both broad sides of the body, wherein the plaster limiting strip only partially penetrates the foam body in its extension from narrow side to narrow side, and wherein the sealing tape with plaster limiting strip is designed to be rollable.
