Portable Speed Bump Spool for Motorized Roadway Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed bump devices lack a portable and efficient mechanism for deploying and retracting speed bumps across roadways, particularly those that are not integrated into the roadway.
Innovation Solution
A dolly with a rotatable spool and a drive unit that allows a speed bump unit to be rolled out and retracted using a motorized mechanism, enabling deployment and storage of speed bumps on roadways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable speed bump device is used, then ease of deployment is improved, but device complexity increases due to the need for motorized mechanisms
Solution Approach 1:
The speed bump unit is wrapped around the spool in a nested configuration, allowing the deployment mechanism to be compact while maintaining the functionality of a full-speed bump when deployed
Solution Approach 2:
The drive unit automatically rotates the spool to deploy or retract the speed bump unit based on operational conditions, reducing the need for manual intervention and simplifying the overall operation despite the mechanical complexity
2Productivity
If a motorized deployment mechanism is used, then productivity is improved through automated deployment, but device complexity increases
Solution Approach 1:
The drive unit serves multiple functions: it can rotate the spool in first direction to wrap the speed bump unit, rotate in second direction to play out the speed bump unit, and can be controlled to deploy or retract the speed bump as needed, consolidating multiple operations into a single mechanism
3Ease of operation
If speed bump units are stored on a spool, then ease of storage is improved, but device complexity increases due to the spool mechanism
Solution Approach 1:
The speed bump unit is wrapped around the spool in a nested configuration, allowing the deployment mechanism to be compact while maintaining the functionality of a full-speed bump when deployed
Solution Approach 2:
The speed bump unit can be quickly deployed from the spool when needed and then retracted and stored back on the spool, allowing for rapid deployment and recovery cycles
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
Facilitates temporary traffic speed reduction by deploying speed bumps and ensures easy storage and transportation of the speed bump units.
Implementation Method 1
The spool is rotated in a second direction to play the speed bump unit outwardly from the spool so that the speed bump unit can be laid across a roadway
Implementation Method 2
The spool is rotated in the first direction to roll the speed bump unit around the spool for storage

AI summary
A portable speed bump assembly includes a dolly and a spool that is rotatably attached to the dolly. A speed bump unit is rolled around the spool and the speed bump unit is played outwardly from the spool when the spool is rotated in a second direction to laid the speed bump unit across a roadway. The speed bump unit compels traffic on the roadway to slow down while driving over the speed bump unit thereby reducing the average speed of the traffic. The speed bump unit is rolled around the spool when the spool is rotated in the first direction for storing the speed bump unit. A drive unit is attached to the dolly and the drive unit is in mechanical communication with the spool for rotating the spool in either the first direction or the second direction.
