Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If deep learning technologies are applied for rock identification, then identification accuracy and speed are improved, but the requirement for large volume of high-quality images increases, which is difficult to meet in actual construction environments
Solution Approach 1:
The system dynamically adjusts lighting intensity through controllable light sources and rotates the rock specimen at different angles using a rotating stage, enabling diverse image acquisition under varying conditions to generate sufficient training data
Solution Approach 2:
The invention changes multiple parameters including light intensity, dust concentration, and rock rotation angle to capture images under diverse conditions, thereby generating large volumes of varied high-quality images for deep learning training
2Device complexity
If images are acquired in natural lighting conditions, then equipment complexity is reduced, but image quality varies due to changing light intensity and weather conditions
Solution Approach 1:
The system pre-arranges controllable light sources and a rotating stage before image acquisition, enabling consistent lighting conditions and systematic multi-angle imaging to ensure uniform image quality
Solution Approach 2:
The invention replaces reliance on natural lighting with an artificial controllable lighting system, substituting unpredictable environmental light with stable, adjustable light sources to maintain consistent image quality
3Adaptability or versatility
If dust is present in the construction environment, then the authenticity of construction conditions is maintained, but dust creates pattern noises that degrade image quality
Solution Approach 1:
The system controls dust concentration as a variable parameter, allowing images to be acquired under different dust conditions including dust-free environments for high-quality imaging and dust-containing environments for training robustness
Solution Approach 2:
The dust concentration in the chamber can be dynamically adjusted during image acquisition, enabling the system to transition between clean and dusty conditions to generate diverse training data while maintaining image quality
