Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of information are integrated for optimal intersection control, then control accuracy and adaptability are improved, but integration time and processing complexity increase
Solution Approach 1:
The patent segments the intersection control information into multiple independent bit fields, where each bit field represents a specific control parameter (e.g., green light duration, yellow light duration, flash duration). This segmentation allows the system to process and integrate multiple types of information in parallel rather than sequentially, significantly reducing integration time while maintaining comprehensive control capabilities.
Solution Approach 2:
The patent transforms the information integration process from a temporal dimension (processing information one after another) to a spatial dimension (processing multiple information types simultaneously through parallel bit field operations). By representing different control parameters as parallel bit fields, the system can integrate multiple information types in a single processing cycle, eliminating the time penalty associated with sequential integration.
2Speed
If real-time integration of multiple information types is implemented, then response speed to changing situations is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple information processing functions into a unified bit field structure. Instead of requiring separate processing modules for different control parameters, the system combines all necessary information (green light duration, yellow light duration, flash duration, etc.) into a single integrated bit field representation. This merging approach enables real-time processing while reducing system complexity by eliminating redundant processing stages.
Solution Approach 2:
The patent changes the representation format of control parameters from textual or structured data formats to binary bit field formats. This parameter transformation enables efficient bitwise operations that can process multiple information types simultaneously with minimal computational overhead, achieving real-time response without requiring complex processing algorithms.
3Ease of operation
If traditional information integration methods are used, then system simplicity is maintained, but the ability to respond to changing situations deteriorates
Solution Approach 1:
The patent replaces traditional sequential processing mechanisms with parallel bitwise operation mechanisms. Instead of using complex conditional logic and sequential data processing to integrate multiple information types, the system uses simple bitwise operations (AND, OR, NOT) on parallel bit fields. This substitution maintains operational simplicity while dramatically improving the ability to respond to changing traffic situations in real-time.
