Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple distance measuring sensors with different ToF systems are combined, then the measuring range is extended, but the control complexity increases
Solution Approach 1:
A bridge processing part is introduced as an intermediary component between the control part and multiple distance measuring sensors with different ToF systems. This bridge processing part converts and unifies the data formats from various sensors (direct ToF, indirect ToF) into a common format, thereby extending the measuring range while preventing control complexity from increasing. The bridge processing part acts as a mediator that handles the complexity internally, allowing the control part to manage multiple sensors as if they were a single sensor system.
2Area of stationary object
If multiple distance measuring sensors with different ToF systems are combined, then the measuring range is extended, but the data handling complexity increases
Solution Approach 1:
The bridge processing part merges and unifies the data from multiple distance measuring sensors with different ToF systems into a single common data format (depth map). By combining the data processing functions and converting all sensor outputs to a unified format, the system extends the measuring range while reducing data handling complexity. The bridge processing part consolidates the data handling requirements, allowing the control part to process unified information rather than managing separate data streams from each sensor type.
3Area of stationary object
If multiple distance measuring sensors with different ToF systems are combined, then the measuring range is extended, but the operation control becomes cumbersome
Solution Approach 1:
The bridge processing part serves as an intermediary that shields the control part from the operational complexities of managing multiple different ToF sensor systems. By handling the format conversion and data unification internally, the bridge processing part allows the control part to operate the combined sensor system with the same simplicity as controlling a single sensor, thereby extending the measuring range while maintaining ease of operation.
