Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prefabricated fire-protection cable boxes are used, then fire protection functionality is achieved, but installation complexity and number of work steps increase
Solution Approach 1:
The patent combines the feedthrough box, support frame elements, and sealing components into a single integrated device. The support frame elements are directly formed as one piece with the box, eliminating the need for separate base plates and multiple sealing components, thereby reducing installation complexity while maintaining fire protection functionality
Solution Approach 2:
The support frame elements serve multiple functions: they provide structural support for wall panels, integrate with the feedthrough box, and enable fire-resistant sealing. This multi-functionality reduces the number of separate components needed while achieving comprehensive fire protection
2Adaptability or versatility
If multiple separate components are used for feedthrough box installation, then adaptability is improved, but device complexity and installation time increase
Solution Approach 1:
By forming the support frame elements and box as a single integrated component, the patent reduces the number of assembly steps required during installation, thereby reducing installation time while maintaining the adaptability to support various wall panel configurations
3Reliability
If intricate sealing procedures are used, then fire-resistant sealing quality is improved, but ease of operation deteriorates
Solution Approach 1:
The integrated design combines sealing components with the main box structure, eliminating the need for separate sealing procedures. The seal is pre-integrated into the device, maintaining fire-resistant sealing quality while significantly improving installation ease
Solution Approach 2:
The device is designed to provide its own sealing functionality through integrated sealing components that are part of the box structure itself, eliminating the need for separate sealing materials and procedures while maintaining high sealing quality

AI summary
A device produces and seals a line feedthrough directly beneath a ceiling and has a feedthrough box to be fastened to the ceiling, with two opposite open end faces and side walls extending between them, which are open towards the ceiling and are to be closed off by the ceiling, such that the side walls in a state of the box mounted on the ceiling, together with the ceiling, form an axial passage channel which is closed in the circumferential direction. The device also has one or more support frame elements, wherein each support frame element is integrally formed or fixed on the side walls of the box on the outside thereof, and extends radially outwards in such a way that it forms an essentially planar bearing surface for supporting a wall panel, when a vertical wall is being produced or closed off around the box.
