Coaxial Pivot Gate Post with Internal Hydraulic Dampener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional industrial pedestrian gate systems are difficult and expensive to manufacture, install, operate, and maintain, particularly due to the need for external hinges and complex electro-mechanical lock mechanisms that require buried wires and are not fail-safe in power failures.
Innovation Solution
A hydraulic closer and dampener system that allows the gate to pivot on an axis coaxial to a cylindrical post, eliminating external hinges and enabling easy access for maintenance, with an electro-mechanical lock installed vertically in a latch post for secure operation and automatic closing speed adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external hinges and complex electro-mechanical lock mechanisms are used, then the gate can achieve secure locking functionality, but the manufacturing cost, installation complexity, and maintenance difficulty increase significantly
Solution Approach 1:
The patent merges the hinge mechanism and locking mechanism into a single integrated post assembly. The post contains both the pivot axis for hinge functionality and the electro-mechanical lock components within its structure, eliminating the need for separate external hinges and reducing overall system complexity while maintaining secure locking functionality
Solution Approach 2:
The post structure serves multiple functions simultaneously: it acts as the mounting support, contains the hinge pivot axis, houses the electro-mechanical lock mechanism, and provides the structural framework for the gate. This multi-functional design reduces the number of separate components needed and simplifies both manufacturing and installation
2Reliability
If electro-mechanical lock mechanisms with buried wires are used, then secure locking is achieved, but the system becomes vulnerable to power failures and requires complex wiring installation
Solution Approach 1:
The electro-mechanical lock mechanism is designed with self-service capabilities during power failures. The system includes backup power sources or energy storage components within the post that automatically activate when main power fails, allowing the lock to maintain functionality or automatically release to prevent trapping occupants, without requiring external intervention or complex wiring modifications
3Shape
If the closer mechanism is integrated internally within the post, then the appearance is clean and modern, but the maintenance access becomes more difficult
Solution Approach 1:
The post is segmented into functional modules that can be independently accessed for maintenance. The closer mechanism is housed in a separate accessible compartment or can be removed as a complete module from the post, allowing technicians to service the internal components without damaging the aesthetic exterior finish, thus maintaining both clean appearance and ease of repair

Function Achieved in This Case
The solution provides a cost-effective, easy-to-maintain gate system that ensures secure and reliable operation, including fail-safe functionality during power failures, with a clean and modern appearance by integrating the closer mechanism internally within the post.

AI summary
A hydraulic closer and dampener that can be removed and replaced by opening a post cap to then lift an internal closer assembly out of the top of an internally pivotable shaft inside a free-standing floor-mounted post. The remainder of the gate mechanism remains functional during such service. An automatic closing speed adjustment is easy to access and set. There are no external hinges, the gate pivots on an axis coaxial to the cylindrical post.
