Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual determination by users is used to select means for shortening manufacturing time, then users can understand various functions, but it becomes difficult to determine the effectiveness of each means in reducing overall manufacturing time
Solution Approach 1:
The patent introduces an information processing device as an intermediary between the user and the manufacturing system. This device automatically calculates and presents the effectiveness of each shortening means, serving as a mediator that provides objective evaluation data without requiring users to manually determine effectiveness through test machining
Solution Approach 2:
The system enables self-service by automatically evaluating and presenting the effectiveness of each means for shortening manufacturing time. The information processing device independently performs calculations and provides recommendations without requiring user intervention in the evaluation process, allowing users to directly utilize the presented information
2Measurement precision
If test machining is performed to determine effectiveness of means, then accurate effectiveness data can be obtained, but the time and cost required for determination increases
Solution Approach 1:
The patent applies preliminary action by calculating and presenting the effectiveness of each means before actual implementation. The information processing device performs advance calculations based on machining programs and process data to determine which means will be most effective, eliminating the need for time-consuming test machining to evaluate effectiveness
Solution Approach 2:
The system creates a virtual model or copy of the manufacturing process to evaluate means effectiveness. Instead of physically performing test machining, the information processing device simulates and calculates the expected outcomes of each means, providing accurate effectiveness data without physical experimentation
3Adaptability or versatility
If multiple means are available for shortening manufacturing time, then more options exist for optimization, but it becomes difficult for users to select the most effective means
Solution Approach 1:
The patent implements feedback by providing users with evaluated effectiveness information for each available means. The information processing device analyzes the machining program and process data to determine which means will be most effective, then presents this feedback to guide user selection, making the decision process straightforward even when multiple means are available
Solution Approach 2:
The system changes the parameter of information presentation by providing quantitative effectiveness evaluations for each means. Instead of leaving users to qualitatively assess multiple options, the information processing device calculates and presents specific effectiveness parameters, enabling easy comparison and selection among multiple available means
