1Duration of action of stationary object
If a supercapacitor is used to store electrical energy for later use, then the energy can be stored and delivered when needed, but the voltage decreases linearly as charge is delivered, resulting in high percentage of energy being unusable when voltage drops below minimum required level
Solution Approach 1:
The system performs preliminary classification of components by their operating voltage requirements before energy storage. By organizing components into groups based on their minimum voltage needs, the system can deliver charge in a controlled sequence, ensuring that each component group receives energy while the voltage is still sufficient for its operation, thereby maximizing usable energy extraction from the supercapacitor
Solution Approach 2:
The mechatronic system is segmented into multiple component groups, each with specific voltage requirements. This segmentation allows the control unit to manage energy delivery in discrete stages, activating component groups in order of their voltage requirements as the supercapacitor discharges, thus preventing energy waste by ensuring each segment operates within its voltage tolerance
2Reliability
If a battery is used to power the mechatronic system, then voltage is maintained at almost constant level until complete discharge, but the system becomes dependent on battery replacement or recharging which creates environmental sustainability issues
Solution Approach 1:
The system employs self-service energy management where the control unit continuously monitors the supercapacitor's voltage state and autonomously determines which component groups can be activated at each moment. This eliminates the need for external battery replacement or recharging infrastructure, allowing the system to sustain operation using only the harvested energy while maintaining reliable voltage delivery through intelligent load management
Solution Approach 2:
The system dynamically changes operational parameters by adjusting which components are active based on the supercapacitor's instantaneous voltage level. As voltage decreases during discharge, the control unit transitions the system from high-voltage-requiring components to lower-voltage-tolerant components, thereby extending operational duration while maintaining reliability without using batteries
3Quantity of substance
If energy is stored in a capacitor with higher capacity, then more energy can be stored, but more energy is required to reach the voltage needed to use the mechatronic system
Solution Approach 1:
The system performs preliminary matching between component voltage requirements and capacitor discharge characteristics. By selecting components whose operating voltage ranges align with the capacitor's discharge curve, the system ensures that as the capacitor charges to higher capacities, the components are activated at appropriate voltage levels, maximizing the utilization of stored energy while minimizing the proportion lost during the charging phase
