Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electronic components are arranged on separate circuit boards or modules, then each component can be independently designed and manufactured, but the overall device size increases and installation space is consumed
Solution Approach 1:
The patent integrates multiple electronic components (microcontroller, driver circuits, power management, I/O interfaces) into a single integrated circuit chip. This merging eliminates the need for separate circuit boards and modules, dramatically reducing the overall device volume while maintaining independent design capabilities through modular integration architecture
Solution Approach 2:
The integrated circuit is designed to control multiple types of electrical locking devices (electromagnets, motors, actuators) through unified driver circuits and interfaces. This multi-functional design allows a single component to replace multiple specialized components, reducing installation space while maintaining manufacturing flexibility
2Ease of manufacture
If multiple separate electronic components and driver modules are used, then each component can be optimized independently, but the circuit complexity increases and more components are required
Solution Approach 1:
The patent combines microcontroller, driver circuits, power management, and I/O interfaces into a single integrated circuit, reducing the component count from multiple separate modules to one unified device. This integration simplifies the circuit design while preserving independent optimization capabilities through internal module architecture
Solution Approach 2:
The integrated circuit incorporates universal driver circuits that can control multiple types of actuators (electromagnets, motors, actuators) through standardized interfaces. This multi-functionality eliminates the need for separate driver modules for each actuator type, reducing circuit complexity while maintaining component optimization flexibility
3Use of energy by moving object
If separate power supply units are used for electronic components and actuators, then power management can be optimized for each load, but power consumption increases and more components are required
Solution Approach 1:
The patent integrates power management functions directly into the integrated circuit, combining voltage regulation, current control, and power distribution in a single unit. This eliminates the need for separate power supply modules and reduces overall power consumption through optimized power delivery to different actuators
Solution Approach 2:
The integrated circuit acts as an intermediary between the power source and multiple actuators, providing intelligent power management through built-in driver circuits. This mediator function optimizes power distribution to each actuator based on its specific requirements, reducing energy loss while maintaining independent power optimization
4Ease of manufacture
If external driver components are used to control actuators, then actuator control can be optimized independently, but the device size increases and installation becomes more complex
Solution Approach 1:
The patent integrates driver circuits directly into the integrated circuit, combining microcontroller and actuator control in a single unit. This eliminates the need for external driver components and simplifies installation to a single connection point, while maintaining independent actuator control optimization through internal driver architecture
Solution Approach 2:
The integrated circuit incorporates universal driver circuits capable of controlling multiple actuator types (electromagnets, motors, actuators) through standardized interfaces. This multi-functional driver design simplifies installation by providing a single control unit for all actuators while maintaining independent optimization capability
