Engineering Contradiction Analysis
1Productivity
If three-dimensional measurement data is stored in advance for multiple workpieces, then manufacturing efficiency is improved, but the risk of reading incorrect data due to human input error increases
Solution Approach 1:
The system automatically reads the identifier attached to the workpiece and uses it to select the corresponding three-dimensional measurement data from storage. This feedback mechanism ensures that the correct data is always retrieved without human intervention, eliminating input errors while maintaining efficient manufacturing operations.
Solution Approach 2:
An identifier (such as a barcode, QR code, or RFID tag) is introduced as an intermediary between the workpiece and the measurement data. This identifier serves as a unique key that links the physical workpiece to its corresponding digital measurement data, ensuring accurate data retrieval without manual intervention.
2Measurement precision
If an identifier with adjustable projections or recesses is used, then accurate matching of measurement data is achieved, but the complexity of the identifier structure increases
Solution Approach 1:
The identifier incorporates asymmetric features such as projections or recesses at specific positions. These asymmetric characteristics provide unique geometric signatures that enable precise identification and matching of measurement data, while the overall structure remains relatively simple through the use of standard attachment mechanisms.

AI summary
A method of manufacturing a structural object includes: receiving a data set including workpiece three-dimensional measurement data and first specific information of first identifier three-dimensional measurement data associated with the workpiece three-dimensional measurement data; acquiring second identifier three-dimensional measurement data by measuring a three-dimensional shape of the identifier; reading out the workpiece three-dimensional measurement data from the data set including the first specific information that coincides with second specific information of the second identifier three-dimensional measurement data; and determining a machining plan based on the read workpiece three-dimensional measurement data.
