Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual measurement methods are used to measure production pallets and precast concrete components, then measurement can be performed with simple equipment, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent replaces manual mechanical measurement with an automated optical measurement system using depth cameras and image processing. The measuring device captures depth images of the production pallet and components, and a computing unit automatically processes these images to determine production heights and geometric deviations, eliminating the need for manual measurement while significantly improving measurement speed and reducing time loss.
2Measurement precision
If automated depth imaging measurement is implemented, then measurement speed and precision are improved, but device complexity increases
Solution Approach 1:
The patent uses depth cameras to create optical copies (depth images) of the production pallet and precast concrete components. Instead of complex mechanical contact measurement systems, the device captures optical information that is then processed computationally to extract precise geometric data, achieving high measurement precision while keeping the physical device relatively simple.
Solution Approach 2:
The patent introduces depth images as an intermediary between the physical object and the measurement data. The depth camera captures optical information, creates depth images as an intermediate representation, and the computing unit processes these images to derive precise measurements. This intermediary approach simplifies the measurement device while maintaining high precision.
3Manufacturing precision
If comprehensive quality control of production pallets and components is performed, then manufacturing precision and product quality are improved, but the measurement process becomes more complex and resource-intensive
Solution Approach 1:
The patent creates a universal measurement system that can measure both the production pallet itself and the precast concrete components placed on it using the same depth imaging device and processing methodology. This multi-functional approach allows comprehensive quality control of the entire production system without requiring separate specialized measurement devices for each component, thereby improving manufacturing precision while avoiding proportional increases in device complexity.
