Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual or pre-programmed automated perforation methods are used, then the manufacturing process is simple, but the ability to customize perforation matrices based on substrate size and material is lost
Solution Approach 1:
The system dynamically adjusts the perforation matrix parameters (number of rows, columns, spacing) based on the measured substrate dimensions and material properties. The controller modifies the perforation pattern in real-time according to the specific substrate being processed, enabling customization without requiring different pre-programmed setups for each substrate type.
Solution Approach 2:
The system changes key parameters of the perforation process including row spacing, column spacing, number of rows, and number of columns based on substrate characteristics. By varying these parameters dynamically, the system adapts to different substrate sizes and materials, achieving customization while maintaining a single flexible processing system.
2Manufacturing precision
If fixed perforation patterns are used, then the manufacturing process is efficient, but visual defects and structural integrity issues occur
Solution Approach 1:
The system measures the actual substrate dimensions and properties first, then uses this feedback information to calculate and adjust the optimal perforation matrix parameters. This closed-loop approach ensures that each substrate receives a customized perforation pattern that achieves target spacing accuracy while maintaining manufacturing efficiency through automated calculation and execution.
Solution Approach 2:
The system performs preliminary measurement and calculation of the optimal perforation matrix before the actual perforation process. By determining the appropriate number of rows, columns, and spacing in advance based on substrate characteristics, the system ensures manufacturing precision is achieved without sacrificing productivity, as the optimization is completed before production begins.
3Reliability
If perforation density is increased to improve acoustic properties, then acoustic performance improves, but structural integrity and visual appearance deteriorate
Solution Approach 1:
The system optimizes the perforation parameters including density, spacing, and distribution pattern based on substrate material properties and thickness. By carefully adjusting these parameters, the system achieves the desired acoustic performance while maintaining adequate structural integrity and minimizing visual defects through optimized hole distribution.

AI summary
A method for determining a perforation matrix includes selecting a trial value for a number of matrix increments across a length and a width of a first major surface of a substrate, selecting a trial value for a number of rows and columns in the matrix, calculating a row spacing value and a column spacing value, comparing the calculated row spacing and column spacing to the target row spacing value and the target column spacing value in the matrix to determine if the values are within a predetermined tolerance of the target row spacing value and target column spacing value, if the values are not within the predetermined tolerance of the target spacing values, repeating, and, upon calculating values within the predetermined tolerance, selecting the lower of the row spacing value and the column spacing value as the final matrix spacing value of the perforation matrix.
