Engineering Contradiction Analysis
1Use of energy by moving object
If conventional oscillation circuits are used, then oscillation function is achieved, but power consumption is excessive and oscillation activation is slow
Solution Approach 1:
The patent applies dynamics by making the circuit configuration changeable through switches SW1 and SW2 that control the connection states of transistors M3 and M4. The circuit can dynamically switch between different operational modes (oscillation operation and oscillation stop) to optimize both power consumption and activation speed. This is achieved by controlling the switches to connect or disconnect specific transistor components based on the desired operational state.
Solution Approach 2:
The patent changes the electrical parameters of the circuit by controlling the gate terminals of transistors M3 and M4 through switches SW1 and SW2. By changing the connection state of these transistors (ON/OFF states), the circuit parameters such as impedance, gain, and power consumption are adjusted to achieve low power consumption during oscillation stop and high-speed activation during oscillation operation.
2Loss of energy
If power consumption is reduced, then energy efficiency improves, but oscillation activation speed may be compromised
Solution Approach 1:
The patent implements periodic action through the controlled switching of switches SW1 and SW2, which periodically change the operational state of transistors M3 and M4. During oscillation operation, the switches are configured to enable low power consumption mode, while during oscillation stop, they switch to a state that enables rapid activation. This periodic switching between states resolves the contradiction between energy loss and activation time.
Solution Approach 2:
The patent uses feedback mechanisms through the amplification circuit and capacitor connections to monitor the oscillation state and adjust the transistor switching accordingly. The feedback ensures that when power consumption needs to be reduced, the circuit transitions to a low-power state, and when rapid activation is needed, the feedback triggers the switching to restore full operational capability, thus balancing energy loss and activation time.
3Use of energy by moving object
If transistor switching is optimized for low power, then energy consumption decreases, but circuit complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the amplification circuit into distinct transistor components (M1, M2, M3, M4) that can be independently controlled through switches SW1 and SW2. This segmentation allows specific transistors to be switched ON or OFF based on operational requirements, achieving low power consumption without requiring complete circuit redesign. The segmented approach manages complexity by isolating control functions to specific circuit segments.
Solution Approach 2:
The patent implements multi-functionality by designing the transistor switching network to serve multiple purposes: power consumption control, oscillation activation management, and circuit state transition. The same switches SW1 and SW2 that control power consumption also manage the activation sequence, making the circuit components universal and reducing overall complexity despite the advanced functionality.
