Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional access control systems require users to remember specific entry point names or identifiers, then access control security is maintained, but user experience becomes frustrating and operation becomes complex
Solution Approach 1:
The system performs automatic entry point identification and access request submission without requiring user intervention for these tasks. The mobile device automatically detects its location, identifies the nearest authorized entry point, and submits the access request, freeing the user from complex interactions while maintaining security through automated credential verification
Solution Approach 2:
The system changes the operational parameters from manual entry point selection to automated location-based identification. By using wireless signal strength measurements and coordinate geometry calculations, the system dynamically determines the user's position and automatically selects the appropriate entry point, transforming the interaction model from memory-based to sensor-based operation
2Adaptability or versatility
If multiple entry points are available in an access controlled location, then access flexibility is improved, but user confusion increases due to the need to select from multiple options
Solution Approach 1:
The system continuously monitors wireless signal strength from multiple access points and uses this feedback to automatically determine the user's position and identify the nearest authorized entry point. This real-time feedback loop eliminates the need for users to manually select from multiple entry points while maintaining access flexibility through automated route optimization
Solution Approach 2:
The system pre-calculates the optimal entry point based on the user's current position and credentials before the user needs to access the facility. By determining the nearest authorized entry point in advance and automatically submitting the access request, the system eliminates on-the-spot decision-making complexity while preserving multiple access route options
3Measurement precision
If users must manually request access by knowing entry point names, then access control precision is maintained, but time is lost due to the selection process
Solution Approach 1:
The system replaces the manual mechanical process of remembering and entering entry point names with an automated electronic system that uses wireless signal triangulation and coordinate geometry to precisely identify the user's location and the nearest authorized entry point. This substitution maintains precise access control through automated credential verification while eliminating the time-consuming manual selection process
Solution Approach 2:
The mobile device acts as an intermediary between the user and the access control system, automatically performing location determination, entry point identification, and access request submission. This intermediary function maintains precise access control through automated processes while significantly reducing the time required compared to manual entry point selection
