Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If test drillings are carried out to ascertain ground profile, then load-bearing capacity assessment is possible, but measurement precision is reduced due to local variations in ground composition
Solution Approach 1:
The system continuously detects operating variables during foundation element production and compares them with expected values from the ground profile model, providing real-time feedback to identify deviations and update the ground profile assessment, thereby improving both measurement precision and reliability
Solution Approach 2:
A ground profile model is created in advance based on test drillings, which serves as a preliminary reference for comparing actual operating variables during production, enabling more accurate real-time assessment while accounting for local variations
2Productivity
If traditional test drilling methods are used to determine ground profile, then load-bearing capacity can be assessed, but production efficiency is reduced due to labor-intensive manual analysis
Solution Approach 1:
The patent replaces manual mechanical analysis of drill cores with an automated electronic system that detects operating variables and processes data through a control unit, eliminating labor-intensive manual analysis and significantly improving productivity while reducing time loss
Solution Approach 2:
The system automatically detects, processes, and analyzes operating variables without requiring manual intervention for ground profile determination, enabling the system to serve itself in the analysis process and thereby increasing production efficiency
3Manufacturing precision
If ground profile variations are not accurately detected, then production process continues, but manufacturing precision deteriorates due to incorrect load-bearing capacity assessment
Solution Approach 1:
The control unit continuously compares detected operating variables with expected values from the ground profile model, providing real-time feedback that enables immediate identification of ground layer transitions and adjustment of production parameters, thereby maintaining manufacturing precision and reliability
