Road Marker Placement Apparatus with Automated Carriage Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for placing temporary road markers on major roads, such as dual carriageways and motorways, are inefficient as they require manual placement by a worker on a vehicle, which is time-consuming and labor-intensive.
Innovation Solution
A road marker placement apparatus comprising a dispenser, a carriage, and a drive arrangement that allows the carriage to collect and place road markers on the road while being driven in a direction opposite to the vehicle's movement, utilizing a guide member and a suction arrangement for precise placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual placement by a worker on a vehicle is used, then flexibility and adaptability are maintained, but productivity is low and labor intensity is high
Solution Approach 1:
The carriage system is self-propelled by the drive arrangement, automatically moving between collecting and placing positions without requiring manual operation. The system serves itself by autonomously completing the entire placement cycle from marker collection to road placement
Solution Approach 2:
The manual mechanical action of a worker placing markers is replaced by an automated mechanical system comprising the drive arrangement, carriage, and dispenser mechanism. This substitution eliminates human labor while maintaining the placement function through automated mechanical means
2Manufacturing precision
If a worker manually places road markers while seated on a vehicle, then device complexity is low, but manufacturing precision and placement accuracy are insufficient
Solution Approach 1:
The carriage acts as an intermediary between the dispenser and the road surface, providing a controlled platform for precise marker placement. The guide member serves as an intermediary element that ensures accurate positioning and alignment during the placement process
Solution Approach 2:
The placement system is segmented into distinct functional components: the dispenser for marker delivery, the carriage for carrier and placement, the drive arrangement for motion, and the guide member for positioning. This segmentation allows each component to be optimized for its specific function, improving overall precision
3Loss of time
If discrete adhesive portions are deposited along a line and markers are manually placed, then ease of operation is maintained, but loss of time occurs due to the sequential manual placement process
Solution Approach 1:
The drive arrangement enables continuous motion of the carriage between collecting and placing positions, eliminating idle time between operations. The system maintains continuous useful action by seamlessly transitioning through the placement cycle without interruption or manual intervention
Solution Approach 2:
Markers are pre-loaded into the dispenser in readiness for placement. The carriage is pre-positioned at the collecting location before the placement cycle begins. Adhesive is deposited in advance along the designated line, so all components are prepared beforehand to minimize placement time

AI summary
A road marker placement apparatus has a dispenser for dispensing a road marker, a carriage for carrying the road marker dispensed by the dispenser, and a drive arrangement for driving the carriage from a collecting position. At the collecting position, the carriage can collect the road marker from the dispenser. The carriage can place the road marker on the road while being driven by the drive arrangement.
