Frustoconical Concrete Block Safety Device for Vehicle Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for preventing vehicle access to pedestrian areas are either temporary and easily movable or aesthetically unpleasing heavy concrete blocks with limited functionality.
Innovation Solution
A heavy concrete block with a frustoconical shape, equipped with feet for stability and fixing brackets, that can be easily transported and installed, and features decorative and utilitarian accessories such as benches, bicycle racks, and trash cans, allowing for customizable and aesthetically pleasing installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy concrete blocks are used to block vehicle access, then the blocking effectiveness is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The patent combines multiple functions into a single concrete block structure: vehicle blocking, pedestrian seating (integrated benches), bicycle parking (integrated racks), and waste disposal (integrated bins). This merging transforms the purely functional blocking element into a multi-functional urban furniture piece that enhances aesthetic appearance while maintaining blocking effectiveness.
Solution Approach 2:
The concrete block is designed to serve multiple purposes simultaneously: it blocks vehicles, provides seating for pedestrians, offers bicycle parking, and includes waste bins. This multi-functionality reduces the need for separate aesthetic elements and integrates utility with the blocking function, improving overall aesthetic appearance.
2Reliability
If heavy concrete blocks are used to block vehicle access, then the blocking effectiveness is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The concrete block is divided into multiple separable components including the main block, benches, bicycle racks, and waste bins. This segmentation allows the heavy block to be manufactured and transported in manageable pieces that can be assembled on-site, improving ease of installation while maintaining the heavy weight needed for effective vehicle blocking.
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
The solution effectively blocks vehicle access while providing a stable and decorative element that can be easily maintained and customized, enhancing the appearance and functionality of pedestrian zones.
Implementation Method 1
it can be taken by the forks of a lifting device to be placed in the appropriate place or to be removed from its location. The feet stabilize the positioning of the block while clinging it to the surface on which it rests thanks to the pressure exerted by the weight of the concrete body on the feet.
Implementation Method 2
As the safety device is generally installed on a more or less regular surface such as a paved surface in a pedestrian zone, it is difficult to move by simple pushing and thus resists violent shocks that could be produced by a vehicle launched at full speed.
