Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional energy harvesting systems are used, then the system structure remains simple, but the system cannot automatically adjust electronic elements in response to environmental changes
Solution Approach 1:
The power regulator is configured to automatically generate control signals based on variations in input voltage from the power generator, enabling the system to self-adjust the electronic element without external sensors or manual intervention. The regulator monitors its own input conditions and autonomously generates appropriate control signals.
Solution Approach 2:
The power regulator implements a feedback mechanism where it continuously monitors the input voltage from the power generator and adjusts its output control signals accordingly. This closed-loop control enables automatic adaptation to environmental changes through voltage variations.
2Measurement precision
If additional sensors are added to detect environmental changes, then the measurement capability is improved, but the device complexity increases
Solution Approach 1:
The power generator serves multiple functions: it not only provides power to the system but also acts as an environmental sensor through its voltage output variations. The same component that generates power inherently provides environmental information through voltage changes, eliminating the need for separate sensing devices.
Solution Approach 2:
The power regulator acts as an intermediary that translates power generator output variations into meaningful control signals. It mediates between the raw voltage variations and the electronic element, extracting environmental information without requiring dedicated sensors.
3Productivity
If manual control operations are used, then the device complexity remains low, but the productivity and responsiveness to environmental changes decrease
Solution Approach 1:
The power regulator is pre-configured with the logic and circuitry to automatically generate appropriate control signals when it detects voltage variations from the power generator. This preliminary setup enables immediate automatic response to environmental changes without requiring manual programming or intervention.
