Solution Overview
Problem
Existing micro-current shower heads lack an effective method to indicate whether the micro-current has reached an effective value, leading to insufficient beauty effects and user confusion.
Innovation Solution
An indicator light circuit configured for a micro-current, comprising an indicator light module, a logic controller, and a sampling circuit, which compares the sample voltage generated by the micro-current with a preset threshold voltage and turns on the indicator light only when the micro-current reaches an effective value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the indicator light is turned on as long as any micro-current exists, then the indicator light can be easily controlled, but the user is easily misled and cannot know whether the micro-current reaches an effective value
Solution Approach 1:
The patent applies parameter changes by introducing a threshold voltage parameter (first preset threshold voltage) to distinguish between ineffective and effective micro-current states. The logic controller compares the sample voltage against this threshold parameter, and only activates the indicator light when the threshold is exceeded, thereby transforming the indicator's behavior from simply responding to any current to specifically indicating effective current levels.
2Object-affected harmful factors
If the micro-current value is kept low to ensure safety, then safety is improved, but the beauty effect is not achieved because the micro-current is not sufficient
Solution Approach 1:
The patent implements feedback by using the logic controller to continuously monitor the sample voltage generated by the micro-current and compare it against the first preset threshold voltage. This feedback mechanism ensures that the micro-current is maintained at the minimum effective level needed for beauty treatment while preventing it from exceeding safe limits, as the indicator light provides real-time feedback on the current's effectiveness.
3Measurement precision
If the indicator light circuit adds threshold voltage comparison functionality, then the indication accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent uses an intermediary approach by introducing a sampling circuit that converts the micro-current into a measurable sample voltage, and then using a logic controller as an intermediary to compare this voltage against a preset threshold. This intermediary mechanism enables precise detection of effective micro-current levels while keeping the overall circuit design modular and manageable, rather than attempting to measure the micro-current directly.

AI summary
An indicator light circuit configured for a micro-current comprises an indicator light module, a logic controller, and a sampling circuit. The logic controller is configured to compare a sample voltage generated by the micro-current on the sampling circuit with a first preset threshold voltage. When the sample voltage is greater than the first preset threshold voltage, the logic controller outputs a control signal to the indicator light module to drive an indicator light of the indicator light module to be turned on.
