Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous slicing method is used for fine reconstruction of sedimentation structure, then three-dimensional image can be generated, but the process is time-consuming and causes deformation of cut surfaces leading to loss of analysis accuracy
Solution Approach 1:
The flume is divided into multiple independent local freezing flumes, each corresponding to a basic bottom plate. This segmentation allows parallel processing of different sections, significantly reducing the overall reconstruction time while maintaining measurement precision through localized high-resolution scanning.
Solution Approach 2:
The sediment body is quickly frozen before scanning using the local freezing flumes. This preliminary freezing action preserves the sediment structure in its original state, preventing deformation during subsequent handling and scanning processes, thereby maintaining analysis accuracy without requiring time-consuming stabilization procedures.
2Measurement precision
If continuous slicing method is used for fine reconstruction of sedimentation structure, then internal and contour information can be obtained, but deformation of cut surfaces occurs leading to loss of analysis accuracy
Solution Approach 1:
The mechanical slicing process is replaced with non-contact CT scanning technology. The local freezing flumes enable the sediment to be frozen in place and scanned intact, eliminating the need for physical cutting operations that cause surface deformation and loss of manufacturing precision.
Solution Approach 2:
Instead of physically slicing the sediment body, the invention creates a digital copy through CT scanning. The frozen sediment structure is scanned to generate three-dimensional digital models that preserve the original internal and contour information without any physical deformation or loss of precision.
3Area of stationary object
If multiple basic bottom plates are spliced together to form combined bottom plate, then larger flume area can be covered, but splicing gaps create discontinuities in the model
Solution Approach 1:
Elastic adhesive is used as an intermediary material to fill the splicing gaps between adjacent basic bottom plates. This adhesive bonds the plates together while accommodating thermal expansion and contraction, creating a continuous and stable foundation that maintains model integrity across the entire flume area.
Solution Approach 2:
The elastic adhesive's physical properties (such as modulus and thermal expansion coefficient) are selected to match those of the basic bottom plates. This parameter matching ensures that the spliced structure behaves as a unified continuous medium, eliminating discontinuities and maintaining structural stability across the expanded flume area.
