Pier Hatch Control System for Secure Public Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing port areas, isolated by wires and barbed wires, are not accessible to the public, limiting their use for public benefit due to stringent security regulations, which hinders their utilization in densely populated cities with expanded infrastructure.
Innovation Solution
A pier hatch control system that creates a temporary bonded zone and ISPS area by raising a steel and concrete-coated hatch from the ground, equipped with hydraulic actuators, a control center, and security poles with cameras and illumination, allowing controlled access and separation of zones while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If port areas are isolated by wires and barbed wires to ensure security and bonded space status, then security and legal compliance are improved, but public accessibility and public benefit are worsened
Solution Approach 1:
The hatch structure transitions from a static barrier to a dynamic system that can change its state between open and closed positions. The hydraulic actuator enables the hatch to rise vertically from the ground, creating a barrier only when security is required, while allowing public access when the hatch remains flush with the ground surface.
Solution Approach 2:
The system changes the physical parameter of the hatch position (flush with ground vs. raised vertical barrier) to control accessibility. When the hatch is flush with the ground, the area is accessible to the public; when raised to a vertical position, it creates a physical barrier that secures the bonded area.
2Reliability
If large areas are completely closed off for bonded area status, then security and legal compliance are improved, but public interest and urban integration are worsened
Solution Approach 1:
The system segments the bonded area control into discrete hatch units that can be independently operated. Instead of closing entire large areas, only specific hatch locations are raised to create barriers, allowing the rest of the area to remain accessible and useful for public activities.
Solution Approach 2:
The control system acts as an intermediary between security requirements and public access needs. The microprocessor-based control center coordinates the hatch operations, determining which hatches should be raised based on security conditions, thereby mediating between the need for secured bonded areas and public accessibility.
3Reliability
If traditional wire and barbed wire barriers are used, then security is improved, but aesthetic quality and public acceptance are worsened
Solution Approach 1:
The system replaces the traditional mechanical wire and barbed wire barrier system with a hydraulic actuation system that raises solid hatch covers from the ground. This substitution provides equivalent or superior security functionality while eliminating the aesthetic deficiencies of wire and barbed wire barriers.
Solution Approach 2:
The hatch structure utilizes composite construction with steel reinforcement embedded in concrete, combining the strength and durability of steel with the aesthetic and weather-resistant properties of concrete. This composite material approach creates a secure barrier that is also visually acceptable in urban environments.
