Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an electronic circuit is used to control the solenoid with power regulation and pulse width modulation, then energy efficiency and control precision are improved, but the system lacks visual feedback indicators and real-time monitoring capabilities
Solution Approach 1:
The patent introduces an activity indicator that provides visual feedback to users about the system's operational state. This feedback mechanism allows users to monitor whether the solenoid is being activated and whether the door is in the locked or unlocked state, eliminating the information loss while maintaining energy efficiency through controlled solenoid activation.
2Reliability
If the solenoid is powered continuously to maintain door locked/unlocked state, then operational reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic activation of the solenoid through pulse width modulation, where the solenoid is activated only during specific time intervals rather than continuously. This periodic action maintains the door's locked or unlocked state reliably while significantly reducing energy consumption compared to continuous power supply.
Solution Approach 2:
The system uses the microprocessor to automatically control and monitor the solenoid activation, eliminating the need for manual intervention. The microprocessor tracks the door state and activates the solenoid only when necessary, making the system self-regulating and energy-efficient while maintaining operational reliability.
3Device complexity
If no monitoring system is implemented, then device complexity is reduced, but the ability to detect electrical overload and system problems is compromised
Solution Approach 1:
The patent incorporates an activity indicator that provides visual feedback about the system's operational status, including whether electrical overload conditions exist. This feedback mechanism enables users to detect system problems without adding complex monitoring hardware, maintaining simplicity while improving reliability through straightforward visual indicators.
