Solution Overview

Problem

Existing methods for installing safety barriers on concrete floors require on-site tool usage, which can be inconvenient and inefficient.

Innovation Solution

A device comprising a metal wire arch with hooked legs and a flexible branch that can be elastically braced between reinforcing wires, allowing for tool-free installation by hooking onto pre-existing wires during concrete prefabrication or pouring, with a looped end to secure the branch between wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional fixing devices with bases and fixing members are used, then secure anchoring to concrete floor is achieved, but on-site tool usage and complex installation process are required

Engineering Contradiction:
Improveinstallation processVSAvoidfixing device structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The fixing device is segmented into three functional parts: an arch component for engagement with reinforcing wires, a branch component for elastic bracing between wires, and a loop component for securing the branch. This segmentation allows each part to perform its specific function independently, simplifying the overall installation process while maintaining secure anchoring capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The arch and branch components are pre-configured with specific geometries (arch shape, perpendicular branch extension, loop at branch end) that enable automatic engagement with the reinforcing wires during concrete prefabrication or pouring, eliminating the need for on-site tool usage and complex assembly operations

Inventive Principle:
Principle #10Preliminary action

2Reliability

If safety barriers are installed on concrete floors with edges, then worker safety is improved, but installation requires tools and time-consuming procedures

Engineering Contradiction:
Improveworker safetyVSAvoidinstallation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The device is designed to self-anchor to the reinforcing wires through the arch hooking onto one wire and the branch elastically bracing between two wires with the loop securing the branch. This self-service mechanism eliminates the need for external tools or complex installation procedures, significantly improving installation efficiency while maintaining reliable safety barrier functionality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device utilizes elastic deformation of the branch component as a key parameter change mechanism. The branch is extended perpendicular to the arch plane with a length greater than the wire spacing, allowing it to elastically brace between reinforcing wires. This parameter change enables automatic securing without tools, improving both productivity and reliability

Inventive Principle:
Principle #35Parameter changes

AI summary

The device has a metallic wire folded into an arch in a plane, where the arch comprises jambs (2a, 2b) folded for being hooked underneath a reinforcing wire (10). The jamb (2b) is extended after its folding into a branch (5) that extends perpendicular to the plane. The branch has a length that is greater than a distance (D) separating reinforcing wires (10, 11) such that the branch is elastically pressed between the wires (10, 11). An independent claim is also included for a method of fabricating a concrete floor.
