Clamping Fixing Arrangement for Membrane Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing arrangements for attaching a lining framework to structural elements, such as walls or roofs, require piercing vapour-retardant and airtight membranes, compromising their integrity and creating potential weak points for tears, and do not allow for easy correction of installation mistakes.
Innovation Solution
A fixing arrangement that clips and clamps the membrane between a recessed support and a projecting part without piercing, using levers and locking mechanisms that maintain the membrane's integrity and allow for reversible locking to facilitate easy adjustments during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the membrane is pierced to attach the lining framework, then the membrane can be fixed to the structural element, but the integrity, air-tightness and vapour-retardancy of the membrane are compromised
Solution Approach 1:
A fixing arrangement with a support and a device acts as an intermediary between the membrane and the structural element. The device clips and clamps the membrane to the support without piercing it, using a locking mechanism to secure the membrane in place while preserving its integrity and impermeability properties.
Solution Approach 2:
The fixing arrangement is divided into separate components: a support structure attached to the structural element, and a clamping device that secures the membrane to the support. This segmentation allows the membrane to be fixed without direct piercing attachment, maintaining its integrity while achieving secure attachment.
2Strength
If the membrane is pierced for attachment, then the lining framework can be secured, but potential weak points for tears are created
Solution Approach 1:
The fixing arrangement serves as a mediator that transfers the attachment function from direct membrane piercing to a separate clamping mechanism. The device clips the membrane material between components and secures it with a locking mechanism, avoiding stress concentrations and weak points that would result from piercings.
3Adaptability or versatility
If the membrane is pierced to attach the framework, then the lining can be fixed at a distance from the membrane, but the air-tightness and vapour-retardancy are destroyed
Solution Approach 1:
The support structure acts as an intermediary carrier that holds the clamping device at a desired distance from the membrane. This allows the lining framework to be positioned at an optimal spacing while the fixing arrangement maintains secure attachment without compromising the membrane's air-tightness and vapour-retardancy properties.
