Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access gate devices integrate sensors and control technology into a single structure, then access control functionality is achieved, but the footprint and space requirement become substantially large
Solution Approach 1:
The system divides the access control functionality into separate components: a reader support structure with reader devices for authorization, a camera device for detection, and a projector device for visual guidance. These segmented components work together to achieve access control without requiring a large integrated structure, thereby reducing the footprint while maintaining functionality.
Solution Approach 2:
The system transitions from a two-dimensional physical barrier structure to a three-dimensional spatial arrangement where the reader support structure stands vertically, and the projector device uses optical projection onto the floor to create virtual lane markings. This dimensional change allows the system to occupy less floor space while maintaining effective access control zones.
2Reliability
If traditional access gate devices integrate all sensors and technology into the access gate structure, then access control is provided, but the structure becomes heavy and complex
Solution Approach 1:
The system separates the access control technology into independent modules: reader devices mounted on a simple support structure, a separate camera device for detection, and a projector device for visual feedback. This segmentation reduces structural complexity while maintaining comprehensive access control functionality through coordinated operation of the modules.
Solution Approach 2:
The reader support structure serves multiple functions: it provides mechanical support for the reader devices, defines the physical boundary of the access control zone, and works in conjunction with the projector device to create visual guidance. This multi-functionality reduces the need for separate structural elements, simplifying the overall system.
3Difficulty of detecting and measuring
If traditional access gate devices use integrated sensor arrays, then user detection is achieved, but the system becomes expensive and space-consuming
Solution Approach 1:
The camera device acts as an intermediary between the user and the access control system. Instead of using complex integrated sensor arrays within the gate structure, the camera captures images of users approaching the access point, and the control unit processes these images to detect and authenticate users. This intermediary approach enables effective user detection with a more compact and cost-effective system.
Solution Approach 2:
The system replaces traditional mechanical sensor arrays integrated into the gate structure with an optical detection system using a camera device. This substitution allows user detection to be performed from a distance without requiring physical sensors embedded in the gate structure, thereby reducing the space requirement and structural complexity.
