Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hardware devices are used for attendance recording, then attendance can be recorded, but the system requires complex configuration and setup
Solution Approach 1:
The mobile device performs self-configuration by automatically detecting NFC tags at checkpoint stations and extracting checkpoint information without requiring manual setup or configuration by administrators. The system configures itself through automated communication with the server.
Solution Approach 2:
The system uses NFC tags as lightweight copies or representations of the actual checkpoint physical locations. These tags contain encoded checkpoint information that can be read by mobile devices, eliminating the need for complex hardware configuration at each physical location.
2Reliability
If conventional hardware devices are deployed, then attendance recording is possible, but implementation costs are very expensive
Solution Approach 1:
The system replaces expensive hardware attendance devices with inexpensive NFC tags that can be easily attached to physical locations. These tags are low-cost, disposable-like components that provide the necessary functionality without requiring expensive infrastructure.
Solution Approach 2:
Mobile devices serve multiple functions: they act as attendance recording devices, communication interfaces, and data processing units. This eliminates the need for dedicated expensive hardware, as existing mobile devices perform the required functions.
3Reliability
If conventional hardware devices are used, then attendance can be recorded, but scheduled maintenance is required
Solution Approach 1:
The NFC tags and mobile device application perform maintenance-free operation. The system automatically handles data transmission, encryption, and communication with the server without requiring manual intervention or scheduled maintenance by vendors.
Solution Approach 2:
The system replaces mechanical hardware maintenance requirements with wireless communication-based operation. NFC tags have no moving parts and the mobile device handles all processing remotely, eliminating the need for physical maintenance and repair.
4Device complexity
If a single device serves one employee at a time, then device simplicity is maintained, but employees must form long queues during peak periods
Solution Approach 1:
The system segments the attendance recording function across multiple independent mobile devices rather than using a single centralized device. Each employee's mobile device independently records attendance at different checkpoint stations simultaneously, eliminating queues.
Solution Approach 2:
The system transitions from a single-point-of-service model to a distributed multi-point model by utilizing multiple mobile devices and NFC tags across different locations. This spatial distribution enables simultaneous attendance recording without queuing.
5Measurement precision
If biometric devices are used for attendance, then employee identification is accurate, but hygiene concerns arise during peak periods
Solution Approach 1:
The system replaces physical biometric contact (fingerprint scanners, card readers) with wireless NFC communication. Employee identification is achieved through mobile device authentication combined with NFC tag reading, eliminating direct contact between employees and shared hardware surfaces.
Solution Approach 2:
The mobile device acts as an intermediary between the employee and the checkpoint station. Instead of direct contact with biometric sensors, the employee's phone communicates wirelessly with NFC tags, and authentication is handled through the mobile application and server.
