Installation Box Fixing with Pivotable Hooks for Insulated Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening methods for installation boxes in thermally insulated walls and facades fail to provide a secure and permanent fit due to the inability of insulating materials to absorb holding forces, leading to damage and instability.
Innovation Solution
The design incorporates pivotable hook-like molded parts on the installation box or auxiliary frame that protrude beyond the perimeter to engage with the insulating layer, ensuring a secure fit, and can be adjusted using a tool to facilitate easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening methods (retaining claws) are used to secure the installation box, then the installation box can be attached to the wall, but the insulating material is destroyed and the installation box is not seated securely
Solution Approach 1:
The fastening elements are designed as pivotable components that can change their position from retracted to protruding. During installation, they are swung out to engage with the wall structure, providing secure anchoring without requiring excessive force that would damage the insulating material.
Solution Approach 2:
The fastening elements act as intermediaries between the installation box and the wall structure. They transfer the securing function from direct contact (which damages insulation) to an intermediate mechanical engagement system that distributes forces appropriately.
2Reliability
If the fastening elements are always protruding to ensure secure fit, then the installation box is securely anchored, but the installation process becomes complicated and time-consuming
Solution Approach 1:
The fastening elements transition from a static always-protruding design to a dynamic system that can be positioned as needed. During installation, they are swung out to engage the wall; during removal, they are swung in to clear the opening, automating the complexity management.
Solution Approach 2:
The pivotable fastening elements are designed to be actuated by the installation process itself. The act of inserting the installation box automatically swings the fastening elements into their engagement position, and removal automatically swings them clear, eliminating manual adjustment steps.
3Object-affected harmful factors
If adhesive is used to fix the installation box in the recess, then the installation box can be attached without damaging insulation, but the fit is not permanently secure
Solution Approach 1:
The fastening system combines mechanical engagement (protruding elements anchoring into wall structure) with the insulating material layer. This composite approach provides both the security of mechanical fastening and the protection of preserving the insulating material integrity.
Solution Approach 2:
The system transitions from static adhesive bonding (which lacks mechanical strength) to dynamic mechanical engagement where pivotable elements can be actively positioned to provide secure anchoring forces that adhesive alone cannot deliver.

AI summary
The arrangement has an installation socket (1) with an auxiliary frame having fastening units (2) adjusted to a pre-assembling state in a position, where the fastening units lie in a peripheral alignment line of the socket or behind the alignment line in the position. The fastening units are adjusted to an assembling reference state in another position, where the fastening units project over the alignment line in the latter position. A wall or a facade has a recess, aperture or blind hole-like recess for inserting the socket.
