Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If induction loops are used to detect traffic participants, then detection reliability is improved, but installation cost and traffic disruption increase
Solution Approach 1:
The patent replaces mechanical induction loops embedded in the road surface with electromagnetic radiation-based transmitting and receiving devices positioned above the traffic route. This substitution eliminates the need to block roads for installation while maintaining detection capability through electromagnetic reflection from traffic participants.
2Difficulty of detecting and measuring
If camera-based systems are used to monitor traffic routes, then detection capability is improved, but functionality is impaired by pollution and nighttime conditions
Solution Approach 1:
The patent replaces optical camera-based detection systems with electromagnetic radiation-based transmitting and receiving devices. The electromagnetic radiation (e.g., radar waves) is not affected by pollution or darkness, enabling reliable detection in all environmental conditions including heavy pollution and nighttime operations.
3Object-affected harmful factors
If transmitting and receiving devices are used to detect traffic participants, then resistance to pollution and nighttime conditions is improved, but device placement and alignment complexity increases
Solution Approach 1:
The patent performs preliminary calculation of the spatial detection region using a 3D model before actual device installation. This pre-calculation determines the optimal device position and orientation to achieve the desired detection area, simplifying the physical installation process and reducing on-site adjustment complexity.
Solution Approach 2:
The patent transitions from two-dimensional camera imaging to three-dimensional spatial detection region modeling. By calculating detection regions in 3D space and projecting them to 2D measurement planes, the system optimizes device placement considering spatial dimensions, thereby simplifying the alignment process through computational geometry.
4Measurement precision
If a 3D model is used to calculate spatial detection regions, then detection accuracy is improved, but computational effort increases
Solution Approach 1:
The patent calculates the spatial detection region in three-dimensional space and then projects it onto a two-dimensional measurement plane. This dimensionality reduction allows the system to maintain accurate 3D detection capabilities while simplifying the final representation and analysis to 2D, thereby reducing computational complexity for practical implementation.
