Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the oscillator uses a fixed oscillation frequency to control light emitting elements, then the device structure is simple, but the light emitting frequency becomes asynchronous due to temperature changes
Solution Approach 1:
The patent implements dynamic adjustment of the oscillation frequency by the oscillator based on temperature detection. The oscillator transitions from a fixed frequency to a variable frequency system that adapts to temperature changes, allowing multiple electronic devices to maintain synchronized light emitting frequencies despite environmental variations.
Solution Approach 2:
The system employs feedback mechanisms where temperature information is detected and fed back to the oscillator to adjust its oscillation frequency. This closed-loop control ensures that the light emitting frequency remains synchronized across devices by compensating for temperature-induced frequency drift.
2Adaptability or versatility
If the oscillator oscillation frequency changes with temperature, then the device can operate in varying environments, but the light emitting frequency synchronization deteriorates
Solution Approach 1:
The patent changes the oscillation frequency parameter of the oscillator based on temperature conditions. By dynamically adjusting this parameter, the system maintains light emitting frequency synchronization across devices operating in different temperature environments, resolving the contradiction between environmental adaptability and synchronization reliability.
3Device complexity
If the quantity of oscillation times is used as a fixed time reference, then the control is simple, but the time measurement accuracy decreases due to temperature-induced frequency changes
Solution Approach 1:
The system transitions from using a fixed quantity of oscillation times as a time reference to a dynamic reference that adjusts with temperature. The oscillator modifies its oscillation frequency to compensate for temperature effects, maintaining accurate time measurement while keeping the control mechanism relatively simple through automated frequency adjustment.

AI summary
An electronic device capable of adjusting light emitting frequency includes an oscillator used to generate an oscillation signal, a microcontroller connected to the oscillator, and a light emitting module connected to the microcontroller. The microcontroller is used to define that an oscillation times of the oscillator within a unit time period is an original oscillation times. The microcontroller sets a correspondence between a switching period and the original oscillation times. The microcontroller is further used to receive the oscillation signal to calculate a time elapse. The microcontroller is configured to control on or off of the light emitting module according to the switching period and the time elapse.
