Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road safety barrier structures face challenges in achieving a balance between strength to support safety barriers and absorbing collision forces without causing excessive damage, while also being cost-effective and easy to install, as previous designs are either complex, expensive, or lack adequate strength.
Innovation Solution
A supporting post with an open bore and parallel extension, allowing secure clamping of safety barriers on both sides, which increases stability and allows for tilting upon collision, eliminating the need for additional connection members and enabling rapid installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single piece plastic supporting post with a projecting member is used, then the design is simplified, but both the manufacturing and the installation become cumbersome due to the plastic properties and adequate strength is missed
Solution Approach 1:
The patent changes the material parameter from plastic to steel, and changes the structural parameter by providing an open bore with parallel extension corresponding to the diameter of the bore in the form of a cut-out. This allows the post to be manufactured by standard steel fabrication methods while maintaining design simplicity.
Solution Approach 2:
The patent segments the post into distinct functional zones: the main body, the open bore with parallel extension, and the projecting member. This segmentation allows each part to be optimized independently for manufacturing while maintaining overall structural integrity.
2Device complexity
If a single piece plastic supporting post with a projecting member is used, then the design is simplified, but adequate strength is missed
Solution Approach 1:
The patent changes the material parameter from plastic to steel, fundamentally improving the strength characteristics. The steel material provides adequate strength to bear the weight of safety barriers and absorb collision forces while maintaining design simplicity.
Solution Approach 2:
The patent employs steel material that can be considered a composite solution, providing both strength and ductility. The material properties are optimized to balance structural strength with the ability to deform during collision to absorb energy.
3Strength
If conventional supporting posts with C- or I-shaped cross section are used, then they can bear the weight of safety barriers, but they cannot adequately absorb collision forces without causing excessive damage
Solution Approach 1:
The patent introduces dynamic characteristics by allowing the post to tilt and deform during collision. The open bore with parallel extension and projecting member configuration enables controlled deformation and energy absorption while maintaining load-bearing capacity during normal operation.
Solution Approach 2:
The patent optimizes geometric parameters including the open bore with parallel extension corresponding to the diameter of the bore, the C- or I-shaped cross section, and the projecting member dimensions. These parameter optimizations balance strength for normal loading with ductility for collision absorption.
4Strength
If additional connection members and bracing are used to strengthen the supporting post, then the strength is improved, but the installation becomes complicated and expensive
Solution Approach 1:
The patent merges the strengthening function into the post itself by integrating the open bore with parallel extension and projecting member as integral parts of the post structure. This eliminates the need for separate connection members and bracing, simplifying both design and installation while maintaining adequate strength.
Solution Approach 2:
The post structure is designed to be self-sufficient, with the open bore and projecting member configuration providing both strength and barrier attachment capability without requiring additional external components. The post serves multiple functions independently.
