Prefabricated Façade Insulation Fixing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation systems for building façades are laborious and time-consuming due to the manual installation of fixing devices before finishing layers, lacking a prefabricated solution that simplifies this process.
Innovation Solution
A fixing device comprising a stud and stem design, pre-installed on prefabricated insulation sheets, allowing fast and secure attachment to a façade by embedding studs in the sheet and using stems and screws for anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing devices are manually installed before finishing layers, then the insulation sheets can be securely fixed to the façade, but the installation process becomes laborious and time-consuming
Solution Approach 1:
The fixing devices (stud and stem assembly) are pre-assembled in the factory before the insulation sheets are shipped to the construction site. This preliminary assembly eliminates the need for manual installation of fixing devices during construction, significantly reducing installation time and labor while maintaining secure fixing reliability.
Solution Approach 2:
The stud and stem are combined into a single pre-assembled fixing device unit that is integrated with the insulation sheet. This merging of components simplifies the installation process by reducing the number of separate installation steps while ensuring reliable mechanical anchoring to the façade.
2Productivity
If fixing devices are pre-installed on insulation sheets, then the installation process becomes faster and simpler, but the fixing devices must be designed with separable elements that fit together
Solution Approach 1:
The fixing device is segmented into two main components: a stud with a longitudinal hole and a stem. This segmentation allows the components to be pre-assembled in the factory while maintaining the ability to be easily installed on-site. The simple insertion of the stem into the stud's longitudinal hole provides adequate complexity without compromising installation speed.
3Adaptability or versatility
If manual installation methods are used, then traditional insulation systems can be implemented, but the process requires multiple manual steps including drilling, anchoring, and finishing
Solution Approach 1:
The fixing devices are pre-assembled in the factory, transforming a complex multi-step manual process into a simplified installation where the pre-assembled units are simply positioned and secured. This maintains adaptability to different façade types while dramatically improving ease of operation.

AI summary
Fixation device for a façade insulation prefabricated plate comprising: a stud (2) having a proximal head (21) and a distal body (22), the stud (2) further having a first through longitudinal hole (23) having a distally decreasing cross-section; and a stem (3) comprising a proximal portion (31) and a distal portion (32) through which a second longitudinal hole (33) passes, where the proximal portion (31) has an outer surface with a distally decreasing cross-section configured to fit into the first longitudinal hole (23) of the stud (2). Thereby, when the proximal portion (31) of the stem (3) fits into the longitudinal hole (23), at least the distal portion (32) of the stem (3) protrudes distally from the stud (2), the distal portion (32) of the stem (3) being configured to open when a screw (T) is introduced along the second longitudinal hole (33).
