Motorised Demining Unit Liquid Marking System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized units for demining and securing routes at risk face challenges in providing precise and reliable marking over long distances, especially on uneven terrain, and require cumbersome logistics for removing marking equipment.
Innovation Solution
A motorized unit with a reservoir for a liquid marking product, dispensing members on either side for lateral markings, and a central dispensing member for axial markings, allowing for secure and precise guidance of following vehicles without the need for equipment recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If marking studs are used to mark the route, then the route can be marked, but the equipment becomes bulky and the beaconing distance is limited to a few kilometers
Solution Approach 1:
The patent uses a liquid marking product delivered by a pump system to create continuous markings on the ground. The liquid is distributed through nozzles that leave a trailing mark behind the vehicle, enabling long-distance beaconing without the bulk of storing numerous physical studs. The hydraulic/pneumatic delivery system allows continuous supply of marking material from a reservoir.
Solution Approach 2:
The patent changes the state of the marking medium from solid (studs) to liquid (paint or similar substance). This parameter change allows the marking material to be delivered continuously through a pump system rather than requiring physical storage of discrete components, thereby extending beaconing distance while reducing equipment bulk.
2Measurement precision
If central studs are spaced to mark the route, then the route can be marked, but the guidance of following vehicles is not precise and they can shift laterally from the track
Solution Approach 1:
The liquid marking system creates a continuous visual trail on the ground that follows the exact path of the demining vehicle. This continuous marking provides precise guidance for following vehicles, eliminating the uncertainty of spaced studs and preventing lateral shifts from the safe track.
3Reliability
If marking studs are placed on uneven terrain with slopes and reliefs, then the route can be marked, but the plots may overturn and no longer correctly indicate the route to follow
Solution Approach 1:
The liquid marking product is deposited on the ground surface and adheres to uneven terrain, slopes, and reliefs without requiring the marking element to remain upright. This eliminates the problem of overturning studs while maintaining reliable route indication across diverse terrain conditions.
Solution Approach 2:
Changing from solid studs that must maintain upright orientation to liquid markings that conform to the ground surface allows the system to adapt to any terrain condition. The liquid marking remains in place and provides reliable guidance regardless of slope or relief.
4Ease of manufacture
If marking studs are used to mark the route, then the route can be marked, but the studs must be recovered requiring logistics and additional cost
Solution Approach 1:
The liquid marking product is consumed in the process of marking the route, eliminating the need for recovery operations. The marking material is inexpensive compared to the logistics of storing, deploying, and recovering numerous physical studs, and its consumption is the intended function rather than a drawback.
