Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed reference images and classical image processing are used for object recognition, then the system can provide stable recognition under controlled conditions, but the system becomes inflexible and fails under varying lighting conditions and environmental influences
Solution Approach 1:
The patent transitions from static reference image comparison to dynamic machine learning-based recognition. The system uses trained operators that can adapt to varying lighting conditions and environmental factors, making the recognition process flexible rather than rigid. The neural network continuously learns and adjusts to different conditions while maintaining reliable object identification.
Solution Approach 2:
The patent changes the fundamental parameters of image processing by moving from classical algorithms to machine learning-based feature generation. The system uses trained operators with adjustable parameters that can be optimized for different lighting conditions, allowing the recognition system to maintain reliability across varying environmental parameters.
2Ease of manufacture
If classical image processing with structure recognition is used, then the system can identify objects based on predefined structures, but the system cannot flexibly support laboratory routines without fixed trigger mechanisms
Solution Approach 1:
The patent implements a self-service recognition system where the machine learning model automatically identifies objects and triggers appropriate laboratory routines without requiring external trigger mechanisms. The system serves itself by continuously monitoring and autonomously initiating processes based on recognized objects, eliminating the need for fixed initialization points.
Solution Approach 2:
The patent creates a universal recognition system that can support multiple laboratory routines and object types through a single machine learning framework. The trained operators are designed to recognize various objects and trigger different routines, making the system multi-functional rather than requiring separate fixed mechanisms for each routine.
3Measurement precision
If high-quality imaging equipment and controlled lighting are used, then the system achieves accurate object recognition, but the system complexity and cost increase significantly
Solution Approach 1:
The patent replaces complex mechanical and optical systems (high-quality cameras, controlled lighting) with a software-based machine learning solution. Instead of improving hardware quality, the system uses intelligent algorithms that can extract meaningful features from images taken under various conditions, substituting computational complexity for hardware complexity.
Solution Approach 2:
The patent changes the approach from improving image quality parameters (lighting, resolution) to optimizing recognition algorithm parameters. The machine learning model uses trained operators that can extract accurate object information even from lower-quality images, shifting the focus from physical parameters to computational parameters.
