Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional traffic surveillance systems, often utilizing gantries, face challenges with limited working angles, high visual impact, and burdensome maintenance requirements, which hinder efficient tracking and registration of vehicles while increasing costs and disrupting traffic flow.
Innovation Solution
A traffic surveillance system with a carrying structure that positions traffic surveillance devices, including vehicle identity registration and tracking cameras, in an arc-shaped configuration alongside the road, allowing for flexible placement and reduced visual impact, enabling efficient vehicle tracking and registration with minimal disruption to traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gantry is used to position traffic surveillance devices, then the devices can be mounted at a height that allows all vehicles to pass underneath, but the working angles of the devices are restricted and maintenance becomes burdensome
Solution Approach 1:
The carrying structure is positioned in a plane from which the surveillance zone protrudes, transitioning from a traditional overhead gantry to a side-mounted configuration. This dimensional change allows devices to be arranged at different heights and angles without requiring a large overhead structure, thereby improving working angle flexibility while reducing structural complexity
Solution Approach 2:
The devices are arranged in an arc-shaped configuration along the carrying structure, allowing optimal positioning at different angular positions. This curved arrangement enables each device to achieve its ideal working angle toward the surveillance zone, resolving the angle restriction problem while maintaining a compact structure
2Adaptability or versatility
If a large gantry is used to accommodate all devices, then all surveillance functions can be provided, but the visual impact is negative and maintenance is difficult
Solution Approach 1:
The surveillance system is divided into multiple discrete devices mounted along an arc-shaped carrying structure rather than consolidated on a single large gantry. This segmentation allows the system to provide comprehensive surveillance coverage while presenting a lower visual profile, as the distributed devices blend better with the roadside environment
Solution Approach 2:
The carrying structure serves multiple functions: it positions devices at optimal heights and angles, provides structural support, and enables maintenance access without requiring road closure. This multi-functionality allows comprehensive surveillance capabilities to be achieved with a more compact, less visually intrusive configuration
3Object-affected harmful factors
If smaller gantries are used to reduce visual impact, then the structure is less obtrusive, but maintenance requires lifting cranes and road closure
Solution Approach 1:
The carrying structure extends slightly beyond what is minimally required to hold the devices, creating accessible platforms at each device location. This excessive extension provides maintenance personnel with easy access to devices without requiring complex lifting equipment or road closure, while still maintaining a compact overall structure with reduced visual impact
4Reliability
If multiple gantries are deployed to monitor several roads, then accurate surveillance is ensured, but the visual impact and implementation cost increase
Solution Approach 1:
Multiple surveillance functions for several roads are merged into a single carrying structure by arranging devices along an arc that can cover multiple road entries and exits. This consolidation maintains surveillance accuracy across all monitored roads while reducing the total number of separate gantry structures, thereby lowering both visual impact and implementation cost
