Underroof Collar Segmentation for Waterproofing Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Underroof collars are difficult to handle due to their large size and soft material composition, leading to installation errors and incomplete installations, as they are often not compact enough for efficient packaging and transportation.
Innovation Solution
A method involving multiple folding steps and fixation techniques to compact the underroof collar, allowing it to be easily managed during packaging and installation, including folding along specific lines to reduce size and risk of unintentional unfolding, and using attachments like adhesive tape or mounting elements for stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the underroof collar is made large and soft for effective water-proofing coverage, then the water-proofing performance is improved, but the ease of handling and installation is worsened
Solution Approach 1:
The underroof collar is divided into multiple collar members (front, rear, left, right) that can be folded relative to each other along folding lines. This segmentation allows the large collar to be compacted for handling while maintaining its full coverage area when deployed for water-proofing
Solution Approach 2:
The collar members are folded and nested within each other in a compact configuration during storage and transportation. The front collar member can be folded over the rear collar member, and side collar members are folded into the structure, creating a compact package that expands to full size during installation
2Volume of moving object
If the underroof collar is packaged compactly to reduce storage and transportation space, then the volume is reduced, but the risk of installation errors increases
Solution Approach 1:
Mounting elements are pre-attached to the collar members during manufacturing, and the collar is pre-folded into its compact configuration. This preliminary preparation ensures that during installation, the collar only needs to be unfolded and positioned, reducing the risk of errors while maintaining compact packaging
Solution Approach 2:
The patent uses visual indicators such as colored markings or patterns on the collar members to indicate correct orientation and folding configuration. This helps installers quickly identify the correct installation orientation and reduces errors during the unpacking and installation process
3Adaptability or versatility
If the underroof collar is made from soft textile-like materials for flexibility and water-proofing, then the adaptability to roof surfaces is improved, but the stability during handling is worsened
Solution Approach 1:
The soft collar is segmented into multiple rigid or semi-rigid collar members connected by folding lines. This segmentation provides structural stability during handling while maintaining the overall flexibility and adaptability of the complete collar assembly to conform to roof surfaces
Solution Approach 2:
The collar members may use composite construction combining soft waterproof textile layers with stiffer structural layers or attached rigid mounting elements. This composite structure provides both the softness needed for water-proofing conformity and the stability needed for easy handling and installation

AI summary
The invention relates to a method for packaging an underroof collar for use in water-proofing a joint between a roof structure and a window frame. Said method comprises the steps of: Folding along a first folding line extending substantially in parallel to the top and bottom collar members; folding along a second folding line extending substantially in parallel to the top and bottom collar members; folding along a third and a fourth folding line extending substantially in parallel to the side collar members; and fixating the underroof collar in a folded state. It further relates to a packed underroof collar, to a roof window with a packed underroof collar attached to a window frame, and to a method for installing an underroof collar including unfolding steps.
