Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current crossing gate mechanisms require additional components and configurations to convert from an entrance gate to an exit gate, incurring extra costs, shipping time, and maintenance, which is inefficient and costly.
Innovation Solution
A crossing gate mechanism with a configuration logic circuit that operates a brake relay in different modes, utilizing an internal power source to power the brake relay, allowing conversion between entrance and exit gate configurations without additional hardware, and meeting safety regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components and configurations are used to convert an entrance gate to an exit gate, then the gate mechanism can be reconfigured for different functions, but the cost, shipping time, installation time, and maintenance requirements increase
Solution Approach 1:
The gate mechanism is designed with a universal control system that can operate in multiple modes (entrance gate mode and exit gate mode) by changing software configuration rather than hardware. The brake relay and logic circuit are programmed to accept different operational modes, allowing the same physical components to serve different functions without requiring additional parts.
Solution Approach 2:
The system changes operational parameters through software configuration to switch between entrance and exit gate modes. The control logic is modified by changing configuration settings in the logic circuit, which alters the timing and control signals sent to the brake relay, thereby changing the gate's operational behavior without physical modification.
2Adaptability or versatility
If additional components and configurations are used to convert an entrance gate to an exit gate, then the gate mechanism can be reconfigured for different functions, but the conversion time and resource requirements increase
Solution Approach 1:
The gate mechanism is pre-configured with all necessary hardware components for both entrance and exit gate operations. The control system is pre-programmed with the capability to switch between modes, and the configuration settings are prepared in advance. When conversion is needed, only a software configuration change is required, eliminating the need for time-consuming hardware installation or reconfiguration.
3Adaptability or versatility
If additional components and configurations are used to convert an entrance gate to an exit gate, then the gate mechanism can be reconfigured for different functions, but the maintenance requirements and costs increase
Solution Approach 1:
By using a universal hardware platform that can operate in multiple modes, the system reduces the total number of different components that need to be maintained. The same brake relay, logic circuit, and motor serve both entrance and exit gate functions, simplifying the maintenance inventory and reducing the complexity of troubleshooting compared to having separate dedicated systems for each mode.
