Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional 3-D printing is used without filter adjustment, then the printing process is simple, but the output quality is poor with rough surfaces and residues requiring post-processing
Solution Approach 1:
The patent applies preliminary action by performing filter parameter calculations and image blurring/sharpening operations before the actual 3-D printing process. The filter adjusting system determines optimal filter parameters based on the pattern image characteristics in advance, and the blurring and sharpening device processes the images beforehand to prevent surface roughness and residues before they occur during printing.
Solution Approach 2:
The patent introduces an intermediary processing system between the original design and the printing process. This intermediary consists of the filter adjusting system and blurring/sharpening device that modify the pattern images through filter parameter calculations, acting as a mediator to improve printing quality without requiring changes to the fundamental printing mechanism or post-processing operations.
2Manufacturing precision
If post-processing is applied to fix rough areas and residues, then printing quality can be improved, but the manufacturing time and process complexity increase
Solution Approach 1:
The patent prevents the need for post-processing by performing preliminary filter adjustments and image processing before printing. The filter parameters are calculated in advance based on the pattern image, and blurring/sharpening operations are applied beforehand to ensure smooth surfaces and eliminate residues at the source, thereby eliminating the time-consuming post-processing step entirely.
Solution Approach 2:
The patent converts the potential harm of surface roughness and residues into a benefit by using filter parameter calculations to predict and prevent these issues before they occur. The system analyzes the pattern image characteristics and applies appropriate filtering to transform what would be harmful surface defects into smooth, high-quality printed surfaces.
3Manufacturing precision
If high-resolution filtering is applied to all images, then printing quality improves, but the processing time and computational load increase
Solution Approach 1:
The patent applies local quality by determining filter parameters based on the specific characteristics of each pattern image rather than using a uniform high-resolution filter for all images. The filter adjusting system analyzes individual image features and calculates appropriate filter parameters tailored to each image's requirements, applying only the necessary level of filtering to maintain quality while minimizing processing time.
Solution Approach 2:
The patent dynamically changes filter parameters based on the pattern image characteristics. The filter adjusting system varies the resolution and strength of filtering applied to different images or different regions of images, adjusting parameters such as filter size, convolution kernels, and processing intensity to match the specific requirements of each image, thereby optimizing both quality and processing efficiency.
