Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access control terminals include user controls and displays for configuration, then configuration capability is provided, but device complexity and production costs increase
Solution Approach 1:
The configuration functionality is extracted from the access control terminal and transferred to a separate configuration card. The terminal no longer needs built-in user controls and displays for configuration, reducing its complexity and cost while maintaining configuration capability through the external card.
Solution Approach 2:
The configuration card acts as an intermediary device between the user and the access control terminal. It provides the user interface for configuration while communicating with the terminal via wireless communication, eliminating the need for the terminal to include built-in configuration controls.
