Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If preprogrammed control logic is used in luminaires, then the control system is simple to implement, but it cannot adapt to actual environmental characteristics leading to misconfiguration and inefficient energy use
Solution Approach 1:
The luminaire autonomously adapts its control logic by analyzing status indications from other luminaires and identifying patterns independently, without requiring external configuration or intervention. The system serves itself by automatically learning environmental characteristics and adjusting its behavior accordingly
Solution Approach 2:
The control entity receives status indications from other luminaires as feedback about environmental conditions and uses this information to adapt its control logic. The system continuously monitors patterns in the feedback data and adjusts its behavior based on learned insights
2Reliability
If manual configuration is performed for each luminaire, then the control logic can be customized for specific spaces, but it becomes inconvenient or impossible in large installations with high numbers of luminaires
Solution Approach 1:
Each luminaire automatically configures its own control logic by analyzing patterns in status indications from neighboring luminaires. The system eliminates the need for manual configuration by enabling luminaires to self-learn optimal control parameters based on their operational environment
Solution Approach 2:
The control logic parameters are dynamically adjusted based on analyzed patterns from status indications. The system changes operational parameters automatically to optimize lighting performance for different environmental conditions without requiring manual reconfiguration
3Productivity
If luminaires operate independently with preprogrammed logic, then each luminaire is simple to control, but the overall system consumes excessive energy and provides insufficient light levels due to inability to coordinate with neighboring luminaires
Solution Approach 1:
The system merges the operational behavior of multiple luminaires by having each luminaire analyze and respond to status indications from neighbors. This coordination enables the group of luminaires to function as an integrated system, optimizing overall energy consumption and lighting performance
Solution Approach 2:
The luminaire takes preliminary action by adapting its control logic in advance based on patterns detected in status indications from other luminaires. This proactive adjustment allows the system to prepare for upcoming lighting requirements and avoid energy waste
