Fan-Shaped Corner Flashing for Window Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door sealing systems lack a reliable method to ensure a watertight seal against driving rain, as the effectiveness of the overall bond between window/door frames and reveals depends on the skill of installers and cannot be tested in advance, leading to inconsistent water-tightness.
Innovation Solution
A corner section with a fan-shaped design and self-adhesive properties, made from a water-impervious elastic material, that encloses the corner of a window or door frame and connects with the reveal in a watertight manner, creating a second drainage level to divert water outside, using adhesive surfaces for secure bonding and accommodating varying installation tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubber strips are manually cut, glued and fitted to seal gaps between window/door frames and reveals, then a sealing level is achieved, but the process requires great effort and skill, leading to inconsistent water-tightness
Solution Approach 1:
The corner section integrates multiple sealing functions into a single pre-formed component that combines tanking, bonding, and sealing features. This merges the previously separate operations of applying rubber strips, adhesive bonding, and water diversion into one integrated element that ensures consistent water-tightness without requiring manual manipulation or high installer skill.
Solution Approach 2:
The corner section is pre-formed with integrated tanking and bonding features before installation. The adhesive bonding layer is pre-applied and the tanking structure is pre-configured, eliminating the need for on-site cutting, folding, and manual assembly. This preliminary preparation ensures consistent quality independent of installer skill.
2Reliability
If individual components meet waterproofing requirements, then each component is water-tight, but the overall bond between window/door and reveal cannot be tested in advance
Solution Approach 1:
The corner section merges tanking, bonding, and sealing functions into a single integrated component. This ensures that the overall bond between window/door and reveal is designed and manufactured as one unified system rather than separate components, allowing consistent quality control and enabling the overall assembly to meet waterproofing requirements.
Solution Approach 2:
The invention changes the approach from testing individual components to designing an integrated corner section where the overall bond parameters are controlled during manufacturing. The pre-formed nature of the corner section allows for consistent dimensional control and adhesive application, ensuring the overall assembly meets required water-tightness standards.
3Reliability
If a fan-shaped corner section with adhesive surfaces is used, then consistent watertight seal is achieved independent of installer skill, but the device complexity increases
Solution Approach 1:
The corner section merges tanking, bonding, and sealing functions into one integrated component. The fan-shaped design with varying width is pre-formed as a single piece with adhesive surfaces already in place, ensuring consistent water-tightness while the integration of functions actually simplifies the overall installation process despite the sophisticated geometry.
Solution Approach 2:
The corner section features local variations in width (fan-shaped design) and localized adhesive bonding surfaces positioned at specific areas requiring sealing. This local quality approach addresses specific sealing needs at the corner region while maintaining a relatively simple overall form factor that does not require complex assembly procedures.
