Integrated Road Marking Cutter with Suction and Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutter devices for road markings require multiple separate units, including a cutter device, brushing machine, and escort vehicles, making the process costly and labor-intensive, and they often transfer vibrations to the tractor or vehicle, causing technical issues and inefficiencies.
Innovation Solution
A cutter device integrated with a road traffic vehicle, featuring a cutter unit with suction equipment for simultaneous cutting and material collection, an asymmetric support wheel for reduced vibration transfer, and side-shift equipment for versatile operation, allowing a single operator to perform multiple tasks efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate cutter device is used for cutting road markings, then cutting functionality is provided, but multiple separate units (cutter device, brushing machine, escort vehicles) are required making the process costly and labor-intensive
Solution Approach 1:
The patent combines the cutter device and brushing machine into a single integrated unit mounted on a vehicle. The cutter device cuts road markings while the brushing machine simultaneously collects the detached material, eliminating the need for separate units and reducing both cost and labor requirements.
Solution Approach 2:
The vehicle-mounted system performs multiple functions: the cutter device creates road markings, the brushing machine collects material, and the vehicle provides mobility and support. This multi-functional approach replaces the need for multiple specialized units, improving productivity while reducing device complexity.
2Ease of operation
If the cutter device is mounted on a vehicle, then mobility is improved, but vibrations are transferred to the vehicle causing technical issues and reduced performance
Solution Approach 1:
The patent extracts the vibration-generating cutter unit from the vehicle structure by mounting it on a separate, movable platform or frame that can be independently positioned. This separation prevents vibrations from being directly transferred to the vehicle's chassis and technical systems, while the vehicle retains its mobility for transporting the equipment.
3Productivity
If the cutter device operates at higher speeds, then productivity increases, but vibration and impact on the vehicle increase causing technical problems
Solution Approach 1:
The patent introduces an intermediary vibration-dampening mechanism between the cutter device and the vehicle platform. This intermediary structure absorbs and dissipates vibrations and impacts generated during high-speed cutting operations, allowing the system to operate at higher speeds for improved productivity without transferring harmful forces to the vehicle.
4Loss of time
If suction equipment is integrated with the cutter device, then material collection is simultaneous with cutting, but device complexity increases
Solution Approach 1:
The patent merges the suction equipment with the cutter device into a single integrated system. The suction inlet is positioned adjacent to the cutter blade, allowing detached material to be immediately captured and removed. This integration eliminates the time loss associated with separate material collection operations while the compact design minimizes the increase in overall device complexity.

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 integrated system enables cost-effective production of road markings at higher speeds with reduced vibration transfer, improving ergonomics and operational efficiency by combining cutting and material collection in a single machine.
Implementation Method 1
suction equipment arranged at least partially in the vicinity of the cutter unit for sucking road surface material produced that detaches during the cutting process from the road surface
Implementation Method 2
an asymmetric support wheel (20) mounted with bearings to the cutter frame for supporting the cutter unit against the road surface... the asymmetric support wheel for reduced vibration transfer
