Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If reference information such as blind spot information is displayed from various angles that differ from the operator's point of view, then the operator can obtain comprehensive spatial information, but it becomes difficult for the operator to promptly ascertain the situation
Solution Approach 1:
Instead of displaying survey information from the survey apparatus's viewpoint, the system transforms and displays the information from the user's viewpoint. This inversion of the reference frame allows operators to see blind spots and external information from their own perspective, making it intuitive and prompt while maintaining comprehensive spatial coverage.
Solution Approach 2:
The system uses an image processing unit as an intermediary to transform survey information between different coordinate systems. This intermediary component converts the three-dimensional survey data from the survey apparatus's coordinate system to the user's coordinate system, enabling accurate representation of external objects from the operator's viewpoint.
2Loss of information
If external information imaged by a camera is displayed to enable the operator to ascertain external information, then the operator can see external objects, but the image does not enable the operator to clearly ascertain depth or structure
Solution Approach 1:
The system merges two types of information: survey information (which provides accurate three-dimensional shape and depth data through ranging) and image information (which provides visual recognition data). By combining these complementary information sources and displaying them together from the user's viewpoint, the system achieves both comprehensive external visibility and clear depth/structure perception.
Solution Approach 2:
The system transitions from two-dimensional camera images to three-dimensional survey information representation. By using ranging data to create three-dimensional shape information and displaying it from the user's viewpoint, the system adds depth perception and structural clarity that plain two-dimensional images cannot provide.
3Measurement precision
If survey information is transformed to the user's viewpoint using imaging apparatuses, then accurate three-dimensional shape information is displayed, but the system complexity increases
Solution Approach 1:
The system replaces complex mechanical multi-camera setups with a more efficient configuration: a single survey apparatus that performs both imaging and ranging functions, combined with computational processing. The image processing unit computationally transforms the survey information between coordinate systems, substituting mechanical complexity with algorithmic processing while maintaining accurate three-dimensional representation.
