Ceiling Cable Hook With Multi-Threaded Shank for Sag Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook apparatuses for hanging cables and extension cord boxes from ceilings are inadequate in preventing sagging, drooping, and electrical hazards, and lack versatility in accommodating different connecting member sizes.
Innovation Solution
A hook apparatus with a shank and bend portion featuring a groove with multiple threaded portions of varying diameters to accommodate different thicknesses, made of non-conductive material, allowing secure attachment to various ceiling structures and preventing electrical conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-diameter threaded groove is used in the hook apparatus, then the structure is simple, but it cannot accommodate connecting members of varied thicknesses
Solution Approach 1:
The groove is segmented into multiple threaded portions (first, second, and third threaded portions) with different diameters along its length. Each threaded portion can accommodate connecting members of different thicknesses, allowing the hook apparatus to adapt to various ceiling structures while maintaining a unified groove structure.
Solution Approach 2:
The groove with multiple threaded portions serves multiple functions: it can accommodate connecting members of varied thicknesses, connect to different ceiling structures, and provide secure attachment points. This multi-functional design eliminates the need for multiple different hook types.
2Reliability
If conventional conductive hooks are used, then the hooks provide strong mechanical strength, but they pose electrical shock hazards in construction environments
Solution Approach 1:
The hook apparatus is made from a composite material that combines mechanical strength with electrical non-conductivity. This composite construction allows the hook to maintain sufficient structural strength for supporting cables and equipment while preventing electrical shock hazards in construction environments.
3Ease of operation
If cables are laid on the ground during construction, then installation is simple, but it creates tripping hazards and equipment damage risks
Solution Approach 1:
The hook apparatus is pre-installed on the ceiling before cable installation. This preliminary action allows cables to be hung and secured in place immediately, preventing them from being laid on the ground and eliminating tripping hazards and equipment damage risks from the outset.
Solution Approach 2:
The hook apparatus serves as an intermediary element between the ceiling structure and the cables. It provides a secure attachment point that elevates cables off the ground, preventing direct contact with the construction environment that could cause tripping hazards or equipment damage.

AI summary
A hook apparatus for hanging a cable, extension cord box and the like is disclosed. The hook apparatus includes a shank and a bend portion. The bend portion extends from the shank. The shank includes a groove. The groove extends the entire length of the shank. The groove includes a first threaded portion, a second threaded portion and a third threaded portion. The first threaded portion has a larger diameter than the second threaded portion. The second threaded portion has a larger diameter than the third threaded portion. Each of the first threaded portion, the second threaded portion and the third threaded portion is configured to receive a connecting member of varied thickness. The connecting member connects to a ceiling. The hook apparatus receives the cable at the bend portion and helps to hold the cable in place and prevent the cable from sagging or drooping.
