Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional glass cutting methods are used with fixed cutting tables and sequential processing, then the cutting process is simple to operate, but the waste proportion is high and material utilization is poor
Solution Approach 1:
The patent implements dynamic cutting sequence optimization where the cutting plan is continuously adjusted based on real-time slab availability, order priorities, and processing progress. The system dynamically reoptimizes cutting patterns to minimize waste while adapting to changing production conditions, rather than using fixed predetermined cutting sequences.
Solution Approach 2:
The system maintains continuous processing by always having multiple slabs in various stages of cutting. When one slab is being processed, others are being prepared or are ready for cutting, ensuring the cutting head operates continuously without idle time, thereby maximizing material utilization and reducing waste.
2Loss of time
If large intermediate storage areas are used to store cut glass pieces, then the glass can be stored for further processing, but the space requirements increase significantly
Solution Approach 1:
The patent implements a nested storage structure where cut glass pieces are stacked vertically in multiple layers on compact racks. Multiple pieces are stored in a nested arrangement, maximizing vertical space utilization and reducing the horizontal footprint of the storage area while maintaining organized inventory for subsequent processing.
Solution Approach 2:
The system transitions from two-dimensional horizontal storage to three-dimensional vertical storage by implementing multi-level racks and stacked storage configurations. This dimensional change allows significantly more glass pieces to be stored in a smaller floor area, reducing space requirements while maintaining storage capacity.
3Productivity
If manual handling and sorting of glass cuttings is used, then the equipment complexity is low, but the handling requirements increase and productivity is reduced
Solution Approach 1:
The system implements automated identification and tracking of glass slabs and cut pieces using RFID tags or barcodes. The glass pieces essentially 'identify themselves' to the control system, which automatically updates inventory records, tracks location, and manages sorting without requiring manual counting or recording, thereby increasing productivity while keeping the automation relatively simple.
Solution Approach 2:
The patent replaces manual mechanical handling with automated conveyor systems and robotic manipulation. The mechanical system automatically transports slabs through the cutting process, moves cut pieces to storage areas, and sorts finished products based on the optimized cutting sequence, significantly increasing processing speed and reducing manual labor requirements.
4Adaptability or versatility
If fixed cutting plans are used for all orders, then the cutting process is straightforward, but the ability to react to market demands is poor
Solution Approach 1:
The system implements continuous feedback loops where the control system monitors order arrivals, slab inventory status, and processing progress in real-time. Based on this feedback, the optimization algorithm continuously adjusts cutting plans to prioritize urgent orders, optimize material usage, and adapt to changing market demands, enabling flexible response while maintaining systematic control.

AI summary
Methods for cutting of raw glass slabs into a number of glass cuttings include determining the supply of uncut or partially cut raw glass slabs, continuously detecting incoming cutting orders and processing of the cutting orders, continuously determining an optimized processing order and optimized cutting patterns of raw glass slabs based on determined values, processing cutting orders according to the determined optimized processing order and optimized cutting patterns, and storing the glass cuttings in assigned compartments of an intermediate storage. An increased productivity with minimized waste of material can be achieved by the continuous optimizing method in regards to the temporal sequence and cutting patterns of the glass cuttings.
