Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing methods are used to create diffuser holes, then the manufacturing process is simpler, but the precision and accuracy of hole geometry replication deteriorates
Solution Approach 1:
The patent replaces traditional manual measurement and calculation methods with a computer-aided manufacturing system that uses digital design models and automated coordinate translation algorithms. The system substitutes mechanical measurement processes with computational geometry transformations, deriving hole positions and vectors directly from CAD models and translating them to machine coordinate systems through software rather than manual calculation.
Solution Approach 2:
The patent introduces a computer-aided manufacturing system as an intermediary between the design model and the manufacturing machine. This intermediary automatically derives hole positions and vectors from the design model, translates coordinates between different reference frames, and generates the manufacturing program, eliminating the need for manual translation and reducing errors.

If manual calculation and translation methods are used, then the equipment required is simpler, but the accuracy of hole position and vector replication deteriorates
Solution Approach 1:
The patent replaces manual calculation and translation processes with automated computer-based coordinate transformation algorithms. The system uses software to derive hole positions and vectors from design models and automatically translates them to machine coordinate systems, eliminating human error in measurement and calculation while maintaining simple equipment requirements.
3Manufacturing precision
If precise coordinate translation is implemented, then the manufacturing accuracy improves, but the complexity of the manufacturing program increases
Solution Approach 1:
The patent introduces a computer-aided manufacturing system as an intermediary that automatically handles the complex coordinate translation and program generation processes. The system translates design model coordinates to machine coordinate systems through automated algorithms and generates the complete manufacturing program, shielding the operator from complexity while ensuring high precision.
Solution Approach 2:
The manufacturing system performs self-service by automatically deriving hole positions and vectors from the design model, translating coordinates without human intervention, and generating the manufacturing program autonomously. This automation handles the complexity internally while providing simple operation to the user.
