Releasable Installation Box Assembly for Replaceable Ceiling Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation boxes for electric wirings in concrete ceilings, such as those described in European patent EP 1 986 299, are not easily replaceable or modifiable, leading to inefficiencies in installation and waste generation.
Innovation Solution
An installation box assembly comprising an installation box and a complementary installation sleeve that can be connected in a releasable manner, allowing pre-installation of electric materials at a remote location and easy replacement on-site, with features like snap connections and blocking mechanisms to secure the box in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the installation box is fixed in the hollow core slab, then the installation is stable and secure, but the installation box cannot be replaced or modified
Solution Approach 1:
The installation system is divided into two separate components: the installation sleeve that remains fixed in the hollow core slab, and the installation box that can be removed and replaced. This segmentation allows the sleeve to provide stable anchoring while the box can be exchanged as needed, resolving the contradiction between stability and replaceability.
Solution Approach 2:
The installation sleeve acts as an intermediary component between the hollow core slab and the installation box. It provides a stable interface with the slab while allowing the box to be inserted, secured, and removed, thereby enabling both stable installation and future replaceability.
2Reliability
If electric installation material is installed on-site, then the installation box is ready for use, but the installation time on-site is increased
Solution Approach 1:
Electric installation material can be pre-installed in the installation box at a remote location or off-site before the box is transported to the building site. This preliminary action ensures the box is ready for immediate use upon installation, while minimizing the time electricians need to spend on-site for material installation.
Solution Approach 2:
The installation process is segmented into separate phases: off-site preparation of the installation box with electric materials, and on-site installation of only the box itself into the sleeve. This separation allows complex material installation to be done elsewhere, reducing on-site time while ensuring installation readiness.
3Reliability
If the installation box is permanently installed in the hollow core slab, then the installation is secure, but the hollow core slab cannot be reused
Solution Approach 1:
The system separates the permanent component (installation sleeve in the hollow core slab) from the removable component (installation box). The sleeve remains as a permanent fixture providing secure installation, while the box can be removed and the hollow core slab reused, thereby reducing waste without compromising installation security.
Solution Approach 2:
The installation box can be removed and discarded or reused, while the hollow core slab with the installed sleeve is recovered and reused. This approach minimizes waste generation by enabling the recovery and reuse of the expensive hollow core slab, while maintaining secure installation through the permanent sleeve.
