Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple dedicated evaluation methods and tools are used for different evaluation items, then evaluation precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple dedicated evaluation methods and tools into a single integrated evaluation system. The apparatus unifiedly processes multiple evaluation items (text clarity, layout, typography, color design, etc.) through one system, eliminating the need to switch between separate tools and reducing operational complexity while maintaining evaluation precision through comprehensive processing capabilities
Solution Approach 2:
The evaluation apparatus is designed with multi-functionality to handle various evaluation items simultaneously. It can evaluate text clarity, layout, typography, color design, and other comprehensibility factors through a single system, making the evaluation process more versatile and reducing the need for multiple specialized tools
2Loss of information
If comprehensive evaluation of multiple evaluation items is conducted, then evaluation completeness is improved, but productivity deteriorates due to great processing load
Solution Approach 1:
The apparatus performs preliminary processing on document data before conducting comprehensive evaluation. This preliminary action prepares the data in advance, organizing and standardizing it to facilitate subsequent multi-item evaluation, thereby reducing the processing load during the actual evaluation phase and improving overall productivity while maintaining completeness
Solution Approach 2:
The evaluation process is divided into segments: preliminary processing of document data, followed by parallel evaluation of multiple items (text clarity, layout, typography, color design). This segmentation allows the system to handle comprehensive evaluation tasks in manageable stages, improving productivity without sacrificing evaluation completeness
3Measurement precision
If coordinate conversion processes are executed for complex file formats, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The apparatus performs coordinate conversion and other preparatory processing on complex file formats during the preliminary processing stage, before the actual evaluation begins. This advance preparation ensures that when evaluation proceeds, the data is already in the appropriate format, maintaining measurement precision while minimizing the time lost to format conversion during the evaluation phase
