Solution Overview
Problem
Existing road safety barriers have low strength at connection points and complex shapes, making them difficult to assemble and requiring high precision.
Innovation Solution
A mobile safety barrier design featuring quadrangle-shaped panels connected by a top connecting element with screw holes and a bottom strip with concave arms that support the panels, simplifying assembly and increasing strength through precise fitting and centring surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing road safety barriers use simple connection designs, then assembly is easier, but strength at connection points is low
Solution Approach 1:
The patent combines multiple connection functions into a single integrated connecting element. The connecting element merges the top connection (via beds and connecting means) and bottom connection (via strip and base) into one unified component that provides both structural support and connection functionality, thereby increasing strength at connection points while maintaining assembly simplicity.
Solution Approach 2:
The connecting element is inserted into the panel structure where it nests within the bed recesses and engages with the strip at the bottom. This nesting arrangement allows the connecting element to be securely positioned within the panel assembly, providing strong connections without requiring complex external fastening mechanisms.
2Strength
If existing barriers use complex shaped connection elements, then strength is improved, but assembly precision requirements increase
Solution Approach 1:
The connecting element features an asymmetric design with a specific shape that corresponds to the bed configuration. The element has a top surface that fits into the bed recesses and a bottom surface that engages with the strip, creating an asymmetric geometry that provides both strength and self-aligning properties during assembly, reducing precision requirements.
Solution Approach 2:
The connecting element has different surface characteristics at different locations: the top surface is shaped to fit the bed recesses for secure engagement, while the bottom surface is configured to engage with the strip. This local differentiation of surface properties provides both strength and ease of assembly without requiring high precision throughout the entire element.
3Strength
If barriers use separate top and bottom connection elements, then connection strength is improved, but device complexity increases
Solution Approach 1:
The patent merges the top connection element and bottom connection element into a single integrated connecting element. This unified component provides both top connection (through engagement with beds and connecting means) and bottom connection (through engagement with strip and base), reducing the number of parts while maintaining connection strength.
Solution Approach 2:
The connecting element serves multiple functions simultaneously: it provides structural support, enables top connection through bed engagement, enables bottom connection through strip engagement, and provides alignment during assembly. This multi-functionality reduces device complexity by eliminating the need for separate components for each function.
