Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power switch controls the motor to operate to produce bubbles, then the bubble machine can function, but the playing method is monotonous and lacks fun
Solution Approach 1:
The circuit is designed to accept multiple types of input signals (manual switch, voice signals, music signals) and process them through a unified control path to operate the motor. This multi-functionality allows the same device to operate in different modes (manual control, voice control, music control) without requiring separate control circuits for each mode, thus improving versatility while keeping the overall structure manageable.
Solution Approach 2:
The patent introduces intermediate signal processing components (amplifier, comparator, signal processing circuit) that act as mediators between different input types and the motor control system. These intermediaries convert various input signals into a standardized control signal that the motor can respond to, enabling multiple control methods without directly complicating the motor control circuitry.
2Ease of operation
If voice control module is added to enable voice control, then user engagement is enhanced, but device complexity increases
Solution Approach 1:
The voice control module is merged with the existing manual control module and music control module into a unified signal processing system. All three input types (manual switch, voice, music) share common signal processing components including the amplifier, comparator, and motor control circuitry. This merging approach allows voice control functionality to be added without creating a completely separate control system, thereby enhancing ease of operation while limiting the increase in overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides an additional control mode for the bubble toy, enhancing user engagement by enabling voice-activated operation alongside traditional manual control.
Implementation Method 1
a microphone control switch S1, a capacitor C1, a capacitor C2, a diode D1, a manual control switch S2, and a microcontroller unit (MCU)... 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
The electric motor generates power to drive the air in the middle of the ring for blowing bubbles to flow

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.
