Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser scanning mechanisms face issues with maintaining the oscillation frequency of scanning flippers, leading to improper transmission and reception of information due to deviations from the benchmark frequency, especially under varying temperature and atmospheric conditions.
Innovation Solution
A method that periodically checks and adjusts the oscillation frequency of the flipper by comparing received signals with stored parameters, using a Digital-to-Analog Conversion value to adjust the drive current signal and store the new value for maintaining the desired frequency, ensuring the scanner operates within predetermined parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scanner operates without frequency monitoring, then the device complexity is reduced, but the reliability of information transmission deteriorates due to frequency deviation
Solution Approach 1:
The patent implements feedback by continuously monitoring the flipper's oscillation frequency and comparing it against a benchmark frequency. When deviation exceeds a threshold, the system automatically adjusts the drive signal to restore the correct frequency, ensuring reliable information transmission without manual intervention
Solution Approach 2:
The scanning system performs self-diagnosis and self-adjustment by autonomously detecting frequency deviations and correcting them through automatic drive signal modification, eliminating the need for external monitoring or manual calibration
2Adaptability or versatility
If the oscillation frequency is manually set during production, then the manufacturing process is simple, but the scanner cannot adapt to environmental changes causing frequency deviation
Solution Approach 1:
The patent transforms the static frequency setting into a dynamic system that continuously adapts to environmental changes. The drive signal frequency is automatically adjusted in real-time based on monitored oscillation frequency deviations, allowing the scanner to maintain optimal performance under varying temperature and atmospheric conditions
3Productivity
If the laser operates continuously, then the scanning productivity is maximized, but the ability to detect frequency deviations deteriorates
Solution Approach 1:
The patent implements periodic action by briefly interrupting the laser operation at scheduled intervals to perform frequency deviation detection and correction. This periodic maintenance approach allows the system to maintain high overall productivity while ensuring accurate frequency monitoring and adjustment

Function Achieved in This Case
This approach enhances scanner quality control by maintaining consistent oscillation frequencies, ensuring proper scanning and data transmission, even under environmental changes.
Implementation Method 1
An electromagnetic coil is disposed adjacent the flipper and a magnetic field producing coil interacts with a permanent magnet disposed on the flipper to move the flipper back and forth
Implementation Method 2
a laser beam is directed incident the mirror surface. As the resonant element oscillates, so too does the mirror, causing the incident laser beam to be scanned across a scanning field

AI summary
A scanner flipper oscillation frequency analyzing method, computer-readable medium, and apparatus is provided. In one embodiment, the method turns a laser off if the laser is on and receives a signal indicative of a flipper oscillation frequency. The method then compares the signal with stored parameters. Based on the comparison, the method adjusts the flipper oscillation frequency when a percentage variation between the signal and the parameters is above a predetermined value. If the flipper oscillation frequency is adjusted a Digital-to-Analog Conversion value associated with the adjustment is stored in memory. The signal received can be transition signals. In other embodiments, an apparatus and computer-readable medium is also provided which performs the similar features recited by the above method.
