Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional adhesive-based roofing membrane installation is used, then strong bonding between membranes is achieved, but installation becomes laborious and time-intensive
Solution Approach 1:
The patent removes the adhesive component from the roofing membrane system entirely. The roofing membranes are designed with self-adhering properties through crosslinked polymers and boron-containing compounds embedded in the membrane material itself, eliminating the need for separate adhesive applications and reducing installation steps.
Solution Approach 2:
The roofing membranes contain crosslinked polymers and boron-containing compounds that enable self-adhesion when membranes overlap. The membranes serve their own bonding function without requiring external adhesives, simplifying the installation process while maintaining reliable bonds.
2Strength
If adhesive is used between roofing membranes, then strong adhesion is achieved, but the system becomes more complex and costly
Solution Approach 1:
The patent combines the adhesive function directly into the roofing membrane material itself through the incorporation of crosslinked polymers and boron-containing compounds. This merging eliminates the need for separate adhesive materials and application systems, reducing overall system complexity while maintaining adhesion strength.
3Reliability
If heat welding is used to join roofing membranes, then watertight seal is achieved, but additional energy and equipment are required
Solution Approach 1:
The roofing membranes contain crosslinked polymers and boron-containing compounds that enable self-adhesion when membranes overlap. The membranes serve their own bonding function without requiring external adhesives, simplifying the installation process while maintaining reliable bonds.
