Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power switch controls the motor to operate, then the bubble machine can produce bubbles, but the playing method is monotonous and lacks fun
Solution Approach 1:
The circuit is designed to support multiple control modes (manual switch control and voice control) within a single system. The microcontroller can process different types of input signals and execute the same motor control function, making the device adaptable to different user preferences and situations without requiring separate circuits for each control method.
Solution Approach 2:
A microcontroller unit serves as an intermediary between the user (via voice or switch) and the motor. It receives various input signals, processes them, and converts them into appropriate motor control commands, enabling the system to handle multiple control methods through a unified interface.
2Ease of operation
If voice control module is added to enable voice activation, then user engagement is enhanced, but circuit complexity increases
Solution Approach 1:
The voice control module is merged with the existing manual control circuitry into a unified system. Both the voice recognition components and the manual switch connect to the same microcontroller, which processes both types of inputs through the same control logic, reducing overall system complexity compared to having separate independent control systems.
Solution Approach 2:
The manual mechanical switch operation is supplemented by a voice-based control system that uses acoustic signals instead of physical contact. The voice control module captures sound waves, converts them to electrical signals, and processes them through the microcontroller, replacing the need for physical switch manipulation with a more convenient voice-based interface.

Function Achieved in This Case
Provides an additional control mode, enhancing user engagement and fun by enabling voice-activated bubble production alongside traditional manual operation.
Implementation Method 1
The voice source signal input module includes a resistor R3, a resistor R6, a resistor R7, a resistor R14, a capacitor C4, a capacitor C5, a capacitor C6, a capacitor C7, a capacitor C8, a capacitor C9, and a microphone MIC
Implementation Method 2

AI summary
A circuit of a novel bubble toy is provided, including a power module E, an execution module, a manual control module, a signal amplification module, and a voice source signal input module. The power module is a 4.5V direct current power source. The power module E includes a port VCC, a port GND, and a port MIC. In the designed circuit, controlling a motor through a switch is reserved. Meanwhile, a voice can be input to a microphone MIC, so that the motor can also be controlled to operate through the voice, thus achieving the same effect as controlling the motor through the switch. For a user, there is one more control mode and one more playing method.
