Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors and monitoring systems are added to detect shelf deformation, then safety monitoring capability is improved, but device complexity increases
Solution Approach 1:
The monitoring system is divided into modular components: deformation sensors attached to individual shelves, wireless communication modules, and centralized processing systems. This segmentation allows the safety monitoring functionality to be added without requiring complete system redesign, thus improving reliability while managing complexity through modular deployment.
Solution Approach 2:
A wireless communication intermediary is introduced between the deformation sensors and the monitoring system, eliminating the need for complex wired connections. This intermediary layer simplifies the overall system architecture by using standard wireless protocols, thus improving safety monitoring capability without proportionally increasing device complexity.
2Loss of time
If real-time monitoring and alert systems are implemented, then safety response time is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic deformation measurements rather than continuous monitoring, with sensors taking readings at scheduled intervals. When no deformation is detected, the system enters a lower-power state. This periodic action maintains safety response capability while significantly reducing average energy consumption compared to continuous real-time monitoring.
Solution Approach 2:
The system uses feedback from deformation sensor readings to dynamically adjust monitoring intensity. When shelves are within safe parameters, monitoring frequency is reduced to conserve energy. When threshold values are approached, the system increases monitoring frequency and activates alert systems, thus optimizing the balance between response time and energy consumption.
