Soil Removal Device with On-Tool Imaging for Adaptive Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil removal devices face challenges in efficiently removing soil material due to varying soil types, as settings optimized for one type, such as sand or clay, can lead to excessive wear when encountering rocky layers, and indirect methods like sound measurement are unreliable for real-time detection.
Innovation Solution
A soil removal device equipped with an image acquisition unit on the excavation tool allows for direct imaging of in-situ soil, enabling immediate detection of soil type, components, and properties, which is then used to control the removal process by adjusting parameters like rotational speed and feed rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If machine parameters (cutting speed and feed rate) are set for sandy or clay soil, then efficient soil removal is achieved, but excessive wear on the removal tool occurs when encountering rocky soil
Solution Approach 1:
The patent applies dynamics by enabling real-time adjustment of machine parameters (cutting speed and feed rate) based on detected soil type. The system transitions from static, pre-set parameters to dynamic, adaptive parameters that change according to the actual soil conditions encountered during drilling, resolving the contradiction between efficiency and tool wear resistance
Solution Approach 2:
The patent implements feedback through a detection device that continuously monitors soil type and feeds this information back to the control system. This closed-loop feedback mechanism allows the system to automatically adjust parameters to match actual soil conditions, preventing excessive tool wear while maintaining optimal removal efficiency
2Adaptability or versatility
If indirect sound measurement methods are used to determine soil type, then soil identification can be performed, but reliable and rapid soil identification becomes difficult due to influence from water content, depth, and machine parameters
Solution Approach 1:
The patent replaces indirect acoustic measurement methods with direct visual detection using an image acquisition device. This substitution eliminates the ambiguities of sound-based indirect measurement and provides direct, unambiguous visual information about soil type, constituents, and properties, significantly improving measurement precision
Solution Approach 2:
The patent uses image capture to create a visual copy of the actual soil at the drill tip location. This optical copy provides direct information about soil characteristics without being influenced by indirect factors like water content or depth, enabling accurate and rapid soil identification
3Measurement precision
If image acquisition unit is arranged on the removal tool, then direct imaging of in-situ soil enables accurate soil type detection, but device complexity increases
Solution Approach 1:
The patent applies universality by integrating the image acquisition device into the existing removal tool structure, allowing the tool to serve multiple functions: both soil removal and soil type detection. This multi-functionality reduces the need for separate dedicated detection equipment, thereby limiting the increase in overall device complexity
