Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of actuators are used to improve the functionality and responsiveness of the electronic device, then the device can perform multiple operations simultaneously, but the power consumption increases and may cause overheating
Solution Approach 1:
The control unit monitors the operational state of each actuator and dynamically adjusts power distribution based on real-time feedback. When certain actuators are not needed for current operations, their power supply is reduced or stopped, preventing unnecessary energy consumption and heat generation while maintaining readiness for future operations.
Solution Approach 2:
The system transitions from static power allocation to dynamic power management. The control unit continuously evaluates which actuators are actively needed and adjusts power distribution in real-time, enabling the device to adapt its resource allocation to current operational demands rather than maintaining constant power supply to all actuators.
2Adaptability or versatility
If a plurality of actuators are used to enhance device functionality, then multiple operations can be performed, but the device size and weight increase
Solution Approach 1:
Multiple actuators are integrated into a unified system with shared control infrastructure. The control unit manages all actuators through a single control interface, and power distribution is consolidated through common power management circuits. This merging approach allows the system to maintain multiple actuators for enhanced functionality while reducing overall system complexity and weight compared to having separate independent actuator systems.
3Device complexity
If existing actuators are controlled without individual power management, then the control system is simple, but power is wasted on actuators that are not currently needed
Solution Approach 1:
Each actuator is equipped with individual power control capability, allowing it to autonomously regulate its own power consumption based on operational needs. The control unit enables actuators to enter low-power or standby modes when not actively required, with each actuator effectively managing its own power state rather than relying on continuous power supply from a centralized source.
