Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user is provided with limited possibilities of influencing the trajectory, then the ease of operation is improved, but the throughput cannot be optimized
Solution Approach 1:
The system automatically determines optimal trajectory parameters by simulating workpiece transport and evaluating conformity with machine parameters. The computer reads machine data, generates candidate trajectories, and selects optimal parameters without requiring extensive user expertise or manual trial-and-error, thus maintaining ease of operation while achieving throughput optimization
Solution Approach 2:
The patent replaces manual trajectory definition and optimization (mechanical/operator-based process) with an automated computer-based simulation and evaluation system. The computer performs automated simulation of workpiece transport, checks conformity with machine parameters, and determines optimal trajectory parameters, substituting the need for operator expertise and manual adjustment
2Manufacturing precision
If the parameters to be defined are so many that parameterizing the trajectory amounts to a complex and lengthy task, then the manufacturing precision can be optimized, but the ease of operation deteriorates
Solution Approach 1:
The system automatically handles the complex task of parameterizing trajectories by reading machine data, generating candidate trajectories with multiple parameters, and selecting optimal values. The computer performs automated simulation and evaluation, eliminating the need for operators to manually define numerous trajectory parameters, thus maintaining manufacturing precision while improving ease of operation
Solution Approach 2:
The patent extracts the complex trajectory parameterization task from the operator's responsibilities and transfers it to an automated computer-based simulation system. The computer handles data reading, candidate generation, simulation, and parameter selection, separating the complex optimization process from manual operation and enabling precise trajectory definition without operator burden
3Manufacturing precision
If extensive trial and error is required to determine suitable trajectories, then the manufacturing precision can be improved, but the loss of time increases
Solution Approach 1:
The system performs preliminary automated simulation and evaluation of candidate trajectories before actual production. The computer reads machine data, generates multiple candidate trajectories, simulates their performance, and pre-determines optimal parameters, eliminating the need for extensive trial-and-error during operation and significantly reducing the time required to achieve precise trajectory optimization
Solution Approach 2:
The patent replaces manual trial-and-error trajectory optimization with an automated computer-based simulation and evaluation system. The computer performs rapid simulation of multiple candidate trajectories, automatically checks conformity with machine parameters, and determines optimal parameters, substituting the time-consuming manual iterative process with efficient automated computation
