Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machining direction is determined by technician experience, then machining expertise can be utilized, but estimation variation increases and training time increases
Solution Approach 1:
The patent replaces the manual, experience-based machining direction determination process with an automated computer-based determination system. The determination unit automatically determines the machining direction based on product data and constraint condition data, eliminating the need for technicians to manually determine machining directions based on their experience. This substitution reduces estimation variation and training requirements while maintaining accurate machining direction selection.
2Reliability
If automated machining direction determination is implemented, then estimation consistency improves, but device complexity increases
Solution Approach 1:
The determination unit serves multiple functions: it receives product data, receives constraint condition data, determines the machining direction based on both inputs, and outputs the determined direction for time estimation. By consolidating these functions into a single multi-functional unit, the system achieves automated machining direction determination without proportionally increasing overall system complexity.
Solution Approach 2:
The system performs self-determination of the machining direction through the determination unit, which automatically analyzes the product data and constraint condition data to select the optimal machining direction without requiring external technician intervention. This self-service capability reduces reliance on human expertise while maintaining consistent and reliable estimation results.
3Productivity
If manual time estimation is used, then flexibility in handling various cases is maintained, but productivity decreases
Solution Approach 1:
The patent replaces the manual time estimation process with an automated calculation system. The time estimation unit automatically calculates machining time based on the determined machining direction, product data, and constraint condition data, eliminating the need for technicians to manually estimate times. This automation significantly increases estimation speed while the system maintains operational simplicity through automated processing.

AI summary
A machining direction determination unit determines a machining direction, i.e., whether to orient a product in a first direction along a material axis or a second direction opposite to the first direction, on the basis of constraint condition data indicating constraint conditions of front machining (first machining) and/or back machining (second machining), and product data. A time estimate output unit calculates a first time estimate required for the front machining and a second time estimate required for the back machining in accordance with the machining direction on the basis of machining condition data indicating machining conditions (including a machining speed) corresponding to tools used respectively for the front machining and the back machining, as well as material data and the product data, and outputs an estimate of a time required to manufacture the product on the basis of the first time estimate and the second time estimate.
