Electric Meter Light-Blinking Function for Noisy Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In noisy environments, such as factories, users often struggle to hear the sound alerts from existing electric meters when measuring short circuits, as the sounds are easily overwhelmed by background noise.
Innovation Solution
The electric meter apparatus incorporates a light-blinking function, utilizing a micro control unit, resistor measuring circuit, and a light-blinking indication unit, such as a backlight module or light emitting diode, to provide visual alerts when a short circuit is detected, ensuring the user's attention is drawn to the measurement results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound alerts are used to indicate short circuit measurements, then the user is reminded of the measurement results, but in noisy environments the user cannot hear the alerts
Solution Approach 1:
The patent transitions from a single auditory alert dimension to multiple dimensions by adding visual light alerts. The light-blinking indication unit provides visual feedback in a different sensory dimension, allowing users to perceive alerts even when auditory channels are blocked by noise.
Solution Approach 2:
The patent makes the alert system multi-functional by combining both sound and light indication capabilities. The light-blinking indication unit works alongside the sound alert, creating a universal alert mechanism that can operate effectively in various environmental conditions regardless of noise levels.
2Reliability
If only sound alerts are provided, then the device structure remains simple, but the alert is not effective in noisy environments
Solution Approach 1:
The patent enhances the indication system to perform multiple functions simultaneously - both auditory and visual alerting. This multi-functional approach ensures reliable communication of measurement results across different environmental conditions without requiring completely separate systems.
Solution Approach 2:
The patent combines sound and light indication mechanisms into a unified alert system. The light-blinking indication unit is integrated with the existing sound alert system, controlled by the same micro control unit, creating a cohesive multi-modal notification system.
3Object-affected harmful factors
If light-blinking indication is added, then alerts are effective in noisy environments, but the device complexity increases
Solution Approach 1:
The patent introduces an optical indication system (light-blinking) to complement the acoustic system, providing noise-resistant alerting. The light-based solution uses LED or backlight technology controlled electronically, avoiding mechanical complexity while achieving the desired noise resistance.

AI summary
An electric meter apparatus with a light-blinking function includes a positive-side probe, a negative-side probe, a resistor measuring circuit, a voltage supply unit, a micro control unit and a light-blinking indication unit. The resistor measuring circuit is configured to measure an external resistor to obtain a resistance value of the external resistor through the positive-side probe and the negative-side probe. The resistor measuring circuit is configured to inform the micro control unit of the resistance value of the external resistor. If the resistance value of the external resistor is less than or equal to a predetermined value, the micro control unit is configured to control the light-blinking indication unit to light, to be turned off or to light blinkingly, in order to remind the user.
