Underwater Milling Surface Leveling on Uneven Waterbeds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milling devices struggle to efficiently remove soil layers from the bottom of bodies of water, particularly in uneven or unknown underwater terrain, lacking the ability to create a stable, horizontal working surface for effective soil extraction.
Innovation Solution
A milling device with a mobile carrier unit and vertically adjustable drive units, aligned horizontally on the waterbed, uses linear guides to position milling units for vertical and horizontal soil removal, allowing for efficient soil extraction even on uneven terrain, with additional units for surface flattening and material recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a milling device is used on uneven underwater terrain, then soil removal capability is improved, but device stability deteriorates
Solution Approach 1:
The milling device employs adjustable support legs that can dynamically adapt their length and positioning to accommodate uneven underwater terrain. This dynamic adjustment capability allows the device to maintain stability while operating on irregular surfaces, resolving the contradiction between soil removal capability and device stability.
Solution Approach 2:
The device is divided into multiple independent support legs rather than a single rigid base. Each support leg can be independently adjusted to match the local terrain conditions, allowing the milling device to stabilize itself on uneven surfaces while maintaining operational effectiveness.
2Adaptability or versatility
If the milling device is positioned on uneven terrain, then adaptability to terrain is improved, but working surface flatness deteriorates
Solution Approach 1:
The support legs incorporate adjustable mechanisms that allow real-time modification of their configuration based on terrain variations. This dynamic adaptability enables the device to conform to uneven surfaces while the milling unit maintains a consistent working height, ensuring flatness of the processed surface.
Solution Approach 2:
Each support leg is designed to independently adapt to local terrain conditions rather than requiring the entire device base to be level. This localized adaptation allows the milling device to accommodate terrain variations while maintaining uniform working conditions at the milling interface.
3Ease of operation
If vertically adjustable drive units are used, then ease of operation on uneven terrain is improved, but device complexity increases
Solution Approach 1:
The drive units are equipped with vertical adjustment capabilities that enable operators to easily adapt the device to uneven terrain by modifying the height of individual drive units. This dynamic adjustability significantly improves ease of operation on varied terrain while the adjustment mechanisms are designed to be relatively simple in construction.
