Cellular Container Floor Fastening With Potted Insert Anchors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fastening systems for metallic cellular shipping container floors struggle to securely attach the flooring to cross-beam members due to the hollow interior of the cellular construction, which self-tapping screws cannot effectively engage.
Innovation Solution
A fastening system comprising a potted insert with a channel and a self-tapping screw, where the insert is embedded in the panel with synthetic resin, and the screw's threaded shaft, optionally fluted, penetrates the cross-beam member to secure the flooring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If metallic cellular flooring is used to reduce weight and enhance strength, then the flooring becomes lightweight and strong, but self-tapping screws cannot effectively engage the hollow interior of the cellular construction
Solution Approach 1:
A potted insert is introduced as an intermediary component between the metallic cellular flooring and the self-tapping screw. The insert is embedded within the hollow cellular structure and provides threaded engagement surfaces, enabling the screw to securely fasten the flooring to the cross-beam member without requiring direct engagement with the hollow cellular interior
Solution Approach 2:
The fastening system is divided into separate functional components: the metallic cellular flooring panel, the potted insert embedded in the panel, and the self-tapping screw. This segmentation allows each component to perform its specific function - the cellular structure provides weight reduction and strength, the insert provides engagement surfaces, and the screw provides fastening force
2Ease of manufacture
If self-tapping screws are used to secure the flooring to cross-beam members, then the fastening process is simple, but the screws cannot effectively engage the hollow interior of the cellular construction
Solution Approach 1:
The potted insert serves as a mediator that combines the simplicity of self-tapping screw installation with the engagement capability needed for hollow cellular structures. The insert remains embedded in the flooring panel and provides pre-formed threaded surfaces that the screw can easily engage without complex pre-drilling or tapping operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system effectively secures the metallic cellular floor to the cross-beam members, providing a strong and lightweight attachment solution that addresses the limitations of traditional self-tapping screws in hollow interiors.
Implementation Method 1
a self-tapping screw disposed within the channel of the potted insert, and including a threaded shaft with tip at a distal end of the shaft, and a screw head at a proximal end of the shaft. In this regard, the tip of the screw and at least a portion of the threaded shaft may be embedded in a cross-beam member abutting a surface of the panel.
Implementation Method 2
A fastening system comprising a potted insert with a channel and a self-tapping screw, where the insert is embedded in the panel with synthetic resin

AI summary
A fastening system for a metallic cellular shipping container floor includes a potted insert with a body disposed between a top flange at one end and a bottom flange at another end. The body defines a channel from the top flange leading towards the bottom flange and has a depth not exceeding a distance from the top flange to the bottom flange. The system also includes a hole formed in a panel of a metallic cellular shipping container floor with a depth identical to or greater than a distance from a top portion of the top flange to a bottom portion of the bottom flange. Finally, the system includes a self-tapping screw disposed within the channel of the potted insert, and including a threaded shaft with tip at a distal end of the shaft, and a screw head at a proximal end of the shaft.
