Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate WLAN and ESL radio modules are used with hardware adaptations to prevent interference, then radio communication reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces hardware-based interference prevention mechanisms with a software-based control system. The control unit coordinates radio activities of both WLAN and ESL modules through software scheduling, avoiding the need for complex hardware adaptations while maintaining communication reliability.
Solution Approach 2:
The control unit serves multiple functions: it manages WLAN radio activities, controls ESL radio module activities, and coordinates between both modules to prevent interference. This multi-functional approach consolidates what would otherwise require separate hardware control mechanisms.
2Use of energy by moving object
If radio activities are coordinated to avoid interference, then energy consumption of electronic display signs is reduced, but control system complexity increases
Solution Approach 1:
The control unit schedules and coordinates radio activities in advance, determining optimal time slots for WLAN and ESL communications before interference occurs. This preliminary coordination allows electronic display signs to enter sleep mode during scheduled WLAN activities, reducing energy consumption while using manageable control logic.
Solution Approach 2:
The control unit autonomously manages the coordination of radio activities without requiring complex external control systems. By integrating the scheduling function within the base station's control unit, the system reduces overall complexity while achieving energy optimization for connected electronic display signs.
3Duration of action of moving object
If predictive coordination of future radio activities is implemented, then interference is minimized and battery life is extended, but processing requirements and control complexity increase
Solution Approach 1:
The control unit predictively schedules future radio activities by analyzing upcoming WLAN and ESL communication needs, coordinating time slots in advance to prevent interference. This allows electronic display signs to optimize their sleep-wake cycles based on predicted radio activity patterns, extending battery life through proactive rather than reactive coordination.
