Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing tapes for windows and doors in building reveals face challenges such as time-consuming installation due to partial retraction and the need for on-site steps, especially with larger elements, and lack effective fire protection mechanisms.
Innovation Solution
A sealing tape with a base body made of expandable foam, surrounded by a detachable retaining means that prevents vertical expansion until activated by heat, allowing for faster installation and providing fire protection by expanding to seal gaps during a fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sealing tape is pre-compressed and ready for immediate use, then installation speed is improved, but the tape may partially retract during installation compromising the seal
Solution Approach 1:
The sealing tape is pre-compressed and mounted on the window frame before installation, ready for immediate use. The retaining means (adhesive tape) holds the foam strip in this pre-compressed state during transport and installation, preventing retraction while enabling quick deployment when needed
2Productivity
If the sealing tape expands immediately upon attachment to the window frame, then the seal is formed quickly, but installation becomes time-consuming due to needing to wait for expansion and perform additional on-site steps
Solution Approach 1:
The sealing system is divided into two functional parts: the foam strip that provides sealing when expanded, and the retaining means (adhesive tape) that controls the expansion timing. This segmentation allows the foam to remain compressed during transport and installation, then expand only when the retaining means is removed at the construction site
Solution Approach 2:
The foam strip is pre-mounted in a compressed state on the window frame during manufacturing, rather than requiring on-site expansion. This preliminary preparation eliminates the need to wait for expansion during installation and removes additional on-site steps, significantly improving installation efficiency
3Object-affected harmful factors
If the sealing tape provides fire protection by expanding to seal gaps during fire, then fire resistance is improved, but the retaining means must be heat-activatable which adds complexity to the material selection
Solution Approach 1:
The retaining means utilizes phase transition (melting) in response to heat from fire. The adhesive tape is selected to melt at temperatures encountered during fire conditions, automatically releasing the foam strip to expand and seal gaps. This heat-activatable mechanism provides fire protection without requiring complex control systems
Solution Approach 2:
The retaining means acts as an intermediary between the heat source (fire) and the sealing function. It translates thermal energy into mechanical action by melting and releasing the foam strip, which then expands to provide the actual fire sealing. This intermediary approach simplifies the overall system while achieving fire protection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quicker installation by ensuring the tape remains compressed until needed and effectively expands to seal gaps during a fire, enhancing fire protection without compromising building integrity.
Implementation Method 1
the foam is expandable at least in this vertical direction... the retaining means is at least section by section releasable in order to allow expansion of the base body
Implementation Method 2
a (in particular ribbon-like and/or film-like) retaining means is provided which surrounds the base body at least section by section and which is suitable and intended to at least partially prevent expansion of the base body in the vertical direction
Implementation Method 3
the retaining means can be released by the application of heat in such a way that an expansion of the base body in the vertical direction is enabled
