Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional ON-OFF switch is used to control an electric load, then the control is simple and reliable, but the operational flexibility is limited (cannot change input voltage or delay circuit breaking)
Solution Approach 1:
The circuit is segmented into multiple functional blocks: a first series circuit with capacitor C1 and load RL1, a second series circuit with capacitor C2 and load RL2, and a diode D. This segmentation allows each component to perform specific functions (voltage storage, voltage division, current direction control) thereby achieving full voltage activation, division voltage operation, and delayed breaking without requiring a complex programmable controller.
Solution Approach 2:
Capacitors C1 and C2 are pre-charged to specific voltages before the switch SW transitions to the OFF state. This preliminary charging action enables the capacitors to maintain voltage and provide delayed breaking effect after the switch opens, as well as enable division voltage operation during the ON state, thereby achieving enhanced operational flexibility without complex real-time control.
2Adaptability or versatility
If capacitors are added to achieve full voltage activation and division voltage operation, then operational flexibility is improved, but device complexity increases
Solution Approach 1:
The capacitors C1 and C2 serve multiple functions simultaneously: they store energy for full voltage activation, divide voltage during operation, and extend breaking time through discharge. The diode D also performs multiple roles by controlling current direction during charging and discharging phases. This multi-functionality reduces the need for additional components, thereby limiting the increase in circuit complexity while achieving enhanced voltage control capability.
3Duration of action of moving object
If series circuits with capacitors and EM effect loads are used, then full voltage activation and delayed breaking are achieved, but circuit complexity increases
Solution Approach 1:
The capacitors C1 and C2 are pre-charged to specific voltages (V1 and V2) before the switch opens. This preliminary energy storage enables the capacitors to continue discharging through the EM effect loads after the switch breaks the circuit, thereby extending the circuit breaking time without requiring additional timing circuits or complex control mechanisms.
Solution Approach 2:
The circuit transitions dynamically between different operational states: during the ON state, capacitors charge through the EM effect loads; during the OFF state, capacitors discharge through the loads. The diode D dynamically controls current direction. This dynamic behavior enables delayed breaking and full voltage activation using simple passive components, avoiding the need for complex active control circuits.
