Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional evaluation methods are used, then the evaluation process is simple, but the accuracy of drape coefficient evaluation is insufficient
Solution Approach 1:
The patent replaces traditional mechanical evaluation methods with a 3D scanning system that uses optical fields to capture fabric draping. The 3D sensor captures multiple images from different angles, and image processing algorithms reconstruct the 3D model to calculate the drape coefficient, substituting mechanical measurement with optical and computational methods to improve accuracy.
Solution Approach 2:
The patent transitions from 2D planar evaluation to 3D spatial evaluation by capturing fabric images from multiple angles and reconstructing the fabric's three-dimensional shape. This dimensional change allows the system to accurately measure the fabric's natural drape and folding characteristics, significantly improving the accuracy of drape coefficient evaluation.
2Measurement precision
If fabric drape is evaluated using static methods, then the measurement process is simple, but it cannot reflect the natural draping of diverse fabrics with mechanical properties
Solution Approach 1:
The patent introduces dynamic evaluation by allowing the fabric to naturally drape under gravity during the measurement process. The 3D scanning system captures the fabric in its natural state without rigid constraints, enabling the evaluation to reflect the actual dynamic behavior of diverse fabrics with different mechanical properties, thereby improving the accuracy of natural drape representation.
3Adaptability or versatility
If advanced fabrics with multiple functions are developed, then fabric versatility improves, but the ability to evaluate drape accurately becomes more difficult
Solution Approach 1:
The patent employs parameter changes by capturing fabric images at multiple angles and using image processing algorithms to extract comprehensive 3D geometric parameters. This allows the system to accurately evaluate the drape characteristics of advanced fabrics with complex mechanical properties, such as elasticity and tensile strength, by analyzing the fabric's shape and deformation from multiple viewing angles.

AI summary
The swiveling table system comprises a 3D sensor and a swiveling table device disposed on a base having a central turntable and a lifting platform. The central turntable includes a central tray and a central rotation column coupled with the central tray for rotating the central tray. The lifting platform includes an outer ring tray and a lifting column coupled with the outer ring tray for lifting the outer ring tray. The outer ring tray and the central tray are coplanar. When a fabric is placed on the coplanar and the lifting column is controlled to lower the outer ring tray in a free-fall manner, the central rotating column rotates the central tray and the 3D sensor captures a rotating image of the fabric to build a 3D model of the fabric.
