Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If strict requirement specifications are set for individual manufacturing devices and manufactured parts, then quality variations are minimized, but manufacturing cost increases
Solution Approach 1:
The patent changes the parameter of quality control from individual device specifications to combination-level quality indices. By calculating quality indices (mean values and standard deviations) for combinations of manufacturing devices based on trace information and inspection information, the system identifies optimal combinations that achieve required quality without imposing strict specifications on each individual device, thereby reducing manufacturing cost while maintaining quality consistency.
2Productivity
If the combination of manufacturing devices is fixed based on initial selection, then production planning is simplified, but the system cannot respond to abnormalities or jamming parts, reducing productivity
Solution Approach 1:
The patent implements dynamic adjustment of manufacturing device combinations during the manufacturing process. The manufacturing management apparatus continuously monitors operation information from manufacturing devices and automatically changes the combination of devices based on real-time quality indices and operational status. This dynamic capability allows the system to respond to abnormalities and jamming parts, maintaining productivity while managing device combination complexity through automated control.
Solution Approach 2:
The patent establishes a feedback mechanism where inspection information from inspected articles is fed back to the manufacturing management apparatus. This feedback is used to calculate quality indices for different device combinations, which then inform automatic adjustments in device selection. The feedback loop enables continuous improvement and adaptation, allowing the system to respond to abnormalities while managing device combination complexity through data-driven decision making.
3Manufacturing precision
If manual correction is used for specified causes of quality variations, then quality issues are addressed, but automatic reduction of quality variations cannot be achieved
Solution Approach 1:
The patent implements a self-service system where the manufacturing management apparatus automatically identifies quality variation causes and corrects them without manual intervention. By analyzing trace information to determine which manufacturing devices were used and calculating quality indices, the system automatically selects optimal device combinations and adjusts manufacturing processes. This automation eliminates the need for manual correction while achieving continuous quality improvement through self-directed process optimization.

AI summary
A manufacturing management apparatus includes an operation information acquisition unit, a trace information acquisition unit, a storage unit, a manufacturing device determination unit, and a transfer destination indication unit. The storage unit stores inspection information on each article in association with the trace information. The manufacturing device determination unit creates combinations of the manufacturing devices that can perform manufacturing processes in consideration of operation information and trace information, determines a quality index from the inspection information for each of the created combinations, and determines, based on the quality index determined for each of the combinations, a combination of the manufacturing devices to be used. A transfer destination indication unit indicates a transfer destination of a part to a transfer device based on the determined combination of the manufacturing devices.
