Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roofing materials require intensive labor and specialized equipment for installation, and they often struggle with flexible application over various roofing profiles and details.
Innovation Solution
A hybrid membrane system comprising a substrate with exposed portions, a membrane layer attached to one side of the substrate, and an adhesive layer attached to the opposite side, allowing for a prefabricated membrane system that can be easily installed over different roofing profiles with maximum flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional roofing materials are used, then waterproofing protection is provided, but intensive labor and specialized equipment are required for installation
Solution Approach 1:
The roofing material is divided into distinct functional layers: a substrate layer for structural support, a membrane layer for waterproofing, and an adhesive layer for bonding. This segmentation allows each layer to be optimized independently and simplifies the installation process by enabling the entire system to be applied as a integrated unit rather than requiring complex multi-step installation procedures
Solution Approach 2:
The invention uses a composite structure combining multiple materials with different properties: the substrate provides tensile strength and dimensional stability, the membrane layer provides waterproofing functionality, and the adhesive layer provides bonding capability. This composite approach enables the material to achieve multiple functions simultaneously, reducing installation complexity and improving ease of operation
2Adaptability or versatility
If traditional roofing materials are used, then waterproofing is achieved, but flexible application over various roofing profiles is difficult
Solution Approach 1:
The membrane layer is designed as a flexible thin film that can conform to various roofing profiles and architectural details. This flexible membrane structure allows the roofing material to be easily applied over curved surfaces, corners, and irregular geometries without requiring specialized installation equipment or techniques, thereby improving adaptability to different roofing profiles
3Reliability
If the membrane layer covers the entire substrate, then waterproofing is maximized, but the substrate cannot be exposed for overlapping installations
Solution Approach 1:
The membrane layer is strategically positioned to cover only the portions of the substrate that require waterproofing protection, while leaving other portions of the substrate exposed. This local coverage approach allows the membrane to provide effective waterproofing where needed while simultaneously enabling exposed substrate areas to be used for overlapping installations and sealing applications, thus resolving the contradiction between waterproofing effectiveness and installation flexibility

AI summary
A system including a first roofing material installed on the roof deck; a second roofing material installed on the roof deck, adjacent to the first roofing material, where the second roofing material includes: a first layer comprising silicone; and a first substrate, where the first layer partially covers a surface of the first substrate, thereby to provide at least a first area of the surface of the first substrate not covered by the first layer, where the first roofing material overlaps at least a portion of the first area; and a flashing material including silicone, where the flashing material covers a portion of each of: the first roofing material, and the first layer of the second roofing material.
