Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the size of the sample is increased to avoid dimensional effects in geotechnical material analysis, then the representativeness of the sample is improved, but the penetrating ability of rays deteriorates and the resolution ratio of the image decreases
Solution Approach 1:
The loading device is segmented into multiple independent loading units, each capable of applying force in different directions. This allows the device to be scaled and configured for different sample sizes while maintaining loading capability, thus accommodating both larger geotechnical samples and CT scanning requirements.
Solution Approach 2:
The invention transitions from conventional single-direction or limited-direction loading to multi-axial loading capability. By adding loading units in multiple dimensions (at least two different directions), the system can apply complex stress states to larger samples without compromising image quality, as the loading forces are distributed across multiple axes rather than concentrated in one direction.
2Force
If the size of the loading device is increased to provide sufficient loading tonnage for larger geotechnical samples, then the loading capacity is improved, but the device complexity and difficulty of placement in CT machine increases
Solution Approach 1:
The loading device is divided into multiple independent loading units, each with its own driving mechanism. This segmentation allows the total loading capacity to be distributed across several smaller, more manageable components that can fit within the CT machine workspace, reducing the complexity of placing a single large loading device.
Solution Approach 2:
Each loading unit is designed with multi-functionality, capable of applying force in different directions and being positioned at various locations on the sample stage. This universal design allows the same basic loading unit structure to serve multiple purposes, reducing overall device complexity while maintaining high loading capacity through coordinated operation of multiple units.
3Ease of operation
If conventional loading methods are used outside the CT machine, then the loading operation is simplified, but the loading accuracy and adjustability deteriorates
Solution Approach 1:
The loading device is merged with the sample stage, forming an integrated system where loading units are directly positioned on the stage and can be precisely controlled during scanning. This combination maintains ease of operation through automated control while dramatically improving loading accuracy and adjustability during the CT scanning process.
Solution Approach 2:
The loading device incorporates dynamic control capabilities, allowing real-time adjustment of loading forces and directions during the scanning process. The driving mechanisms can dynamically modify the magnitude and direction of applied forces, enabling precise control of stress states on the sample throughout the experiment, which significantly improves loading accuracy compared to static conventional methods.
