Spacing Device for Vapor Barrier Membrane Perforation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for maintaining a facing element, such as a plasterboard, at a distance from a vapor barrier membrane are complex to install and often result in membrane perforation or deformation, compromising the airtightness and edge integrity of the vapor barrier.
Innovation Solution
A device comprising a plate that engages with a frame and a fixing member with a portion to perforate the vapor barrier membrane, while compressing it around the perforation zone to maintain tightness and prevent deformation, allowing for easy installation without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vapor barrier membrane is placed between the facing and insulation material to prevent water condensation, then the thermal insulation effectiveness is improved, but the membrane is vulnerable to perforation during drilling operations for electrical and plumbing work
Solution Approach 1:
The patent introduces a third dimension by creating an air gap between the vapor barrier membrane and the facing element. This spatial separation allows drilling operations to be performed on the facing without penetrating the membrane, as the drill bits pass through the air space rather than the membrane itself. The membrane remains intact while still providing its vapor barrier function.
Solution Approach 2:
The patent introduces an intermediary structure (the air gap created by spacing elements) between the facing element and the vapor barrier membrane. This intermediary space serves as a buffer zone that protects the membrane from direct contact with drilling operations, allowing utilities to be installed through the facing without compromising the membrane's integrity.
2Object-affected harmful factors
If a distance of a few centimeters is maintained between the facing and vapor barrier membrane to allow drilling operations, then the membrane is protected from perforation, but the installation complexity increases
Solution Approach 1:
The patent divides the spacing function into discrete, modular components. Instead of requiring a complex continuous spacing system, the invention uses individual spacing elements (such as clips or spacers) that can be independently installed at regular intervals. This segmentation simplifies the overall installation process while maintaining the required air gap distance.
Solution Approach 2:
The spacing elements are designed to be self-installing or easy-to-install components that attach to the facing element and extend perpendicular to create the air gap. The elements may incorporate self-gripping features or simple attachment mechanisms that require minimal tools or expertise, reducing installation complexity while ensuring consistent spacing.
3Object-affected harmful factors
If existing spacing devices are used to maintain distance between facing and membrane, then membrane protection is achieved, but the devices require complex setup and tool-based installation
Solution Approach 1:
The spacing elements are designed as self-installing components that can be attached to the facing element without requiring specialized tools or complex procedures. The elements may feature self-gripping mechanisms, snap-fit attachments, or simple drive-through installations that reduce labor requirements and eliminate the need for specialized installation equipment.
Solution Approach 2:
The patent employs simple, inexpensive spacing elements that can be easily replaced if needed. These elements are designed as basic plastic or metal components with minimal processing requirements, making them cost-effective and easy to install. Their simplicity allows for rapid installation without requiring precision or specialized tools.

AI summary
The invention relates to a device for keeping a facing element, such as plasterboard, at a spacing from a vapor barrier membrane (300) that extends along an insulating material covering a surface, such as a wall or a ceiling, for covering said facing. Said device is characterized in that it includes: a lockplate (1) insertable into a reinforcement (100) rigidly connected to the surface to be covered, and a member (2) intended for attachment of a mounting (200) of the facing element and including a first portion (21), to be inserted into the mounting (200), and a second portion (20) to be inserted into the lockplate. Said portions (20, 21) are at a spacing from each other in a direction that is perpendicular to the surface to be covered. The second portion (20) includes a tip (22) for perforating the vapor barrier membrane (300) when inserting said second portion (20) into the lockplate (1), and in that the lockplate (1) and the attachment member (2) have respective means (14, 12, 22, 23) for compressing the vapor barrier member around the tip (22) in a bearing zone that is coplanar with the membrane.
