Blind Anchoring Device for Exterior Wall Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anchoring techniques for aerial cables and devices on building exteriors are cumbersome, dangerous, and costly due to the need for external access, which is often restricted by weather or structural obstacles, and result in misalignment and additional connection risks.
Innovation Solution
An anchoring device with an external part and internal part, featuring retaining means, support means, and guide means that allow for 'blind' screwing through a wall hole, enabling installation from the interior and reducing external intervention, with a coaxial tube guiding the fixing elements and cable passage for precise alignment and solid fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anchoring techniques using fixing hooks and tensioners are used on external faces, then the cable can be anchored and tension maintained, but the installation becomes dangerous and costly due to required external access at height
Solution Approach 1:
The invention inverts the conventional anchoring approach by performing the fixing operation from the interior of the building rather than from the exterior. The hollow fixing element is inserted through a hole in the external face from inside the building, allowing the operator to work safely from ground level or interior positions while still achieving secure external anchoring of the cable.
Solution Approach 2:
The hollow fixing element acts as an intermediary component that bridges the interior and exterior of the building. It provides a through-hole that allows the cable to pass from the exterior to the interior while being secured by fixing means engaged from the interior side, thus mediating between the external anchoring requirement and internal installation accessibility.
2Ease of manufacture
If external access equipment such as nacelles or scaffolding is used, then anchoring can be performed, but the cost and time consumption increase significantly
Solution Approach 1:
The invention eliminates the need for external access equipment by inverting the installation approach. Instead of accessing the external face from outside the building using nacelles or scaffolding, the fixing element is inserted from the interior through a pre-drilled hole, allowing installation from safe, accessible interior positions without expensive equipment deployment.
3Adaptability or versatility
If the anchoring point is dissociated from the penetration point to allow flexible installation, then cable routing becomes more flexible, but an external housing is required creating additional connection risks
Solution Approach 1:
The hollow fixing element serves multiple functions simultaneously: it acts as the anchoring point for the cable, provides the penetration point through the wall, and serves as the connection point between interior and exterior cables. This multi-functionality eliminates the need for separate external housing while maintaining both routing flexibility and connection reliability.
Solution Approach 2:
The invention merges the anchoring function, penetration function, and connection function into a single integrated hollow fixing element. By combining these previously separate components into one element, the design eliminates the need for external housing while ensuring reliable cable connections between the aerial cable and interior cable.

AI summary
A device, kit, and method are provided for anchoring an element on an exterior face of a wall of a building. The method includes, from the inside of the wall, running a line into a hole passing through the wall and fixing said line to an element anchoring device. The device comprising a fastener of said element, a bearing means, a first fixing means and a guide able to guide a second fixing means that collaborates with said first means. The method includes, from the inside, pulling said line in order to introduce the guide into said hole and, from the inside and using the guide, fixing the two fixing means together to press the bearing means firmly against the exterior face of the wall.
