Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-forming devices face reduced image quality and user experience due to inaccurate environmental parameter determination when the primary sensor becomes abnormal, as they rely solely on this sensor for real-time adjustments.
Innovation Solution
The controller of the image-forming device determines environmental parameters like temperature and humidity in real-time using additional target apparatuses within the device, allowing for adjustments of control parameters even when the primary sensor is abnormal, thereby ensuring accurate and effective image formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one sensor is disposed in the image-forming device, then the device complexity is reduced, but the reliability of environmental parameter detection deteriorates when the sensor becomes abnormal
Solution Approach 1:
The patent divides the detection function into multiple independent sensors (first sensor and second sensor) that can independently detect environmental parameters. When one sensor becomes abnormal, the other sensor can continue to provide detection data, ensuring continuous operation and improved reliability of environmental parameter detection.
Solution Approach 2:
The patent implements a backup sensor (second sensor) in advance to cushion against the potential failure of the primary sensor (first sensor). This redundant configuration ensures that if the primary sensor becomes abnormal, the system can immediately switch to the backup sensor without interruption, maintaining detection reliability.
2Device complexity
If only one sensor is used for detection, then the device complexity is reduced, but the measurement precision of environmental parameters deteriorates when sensor abnormality occurs
Solution Approach 1:
The detection function is segmented into multiple sensors, allowing the system to compare and validate readings from different sensors. This segmentation enables the controller to identify and exclude abnormal sensor data, maintaining measurement precision even when one sensor fails.
Solution Approach 2:
The patent implements a feedback mechanism where the controller continuously monitors sensor outputs and compares them against expected ranges. When sensor abnormality is detected, the system provides feedback to switch to the backup sensor, ensuring measurement precision is maintained through continuous validation and correction.
3Productivity
If the primary sensor becomes abnormal, then the device can continue operating, but the image quality deteriorates due to inaccurate environmental parameter data
Solution Approach 1:
The backup sensor is configured in advance to cushion against primary sensor failure. When the first sensor becomes abnormal, the controller automatically switches to the second sensor, ensuring continuous operation without interruption while maintaining accurate environmental parameter data for image formation.
Solution Approach 2:
The controller continuously monitors sensor data quality and provides feedback to switch between sensors based on detected abnormalities. This feedback mechanism ensures that accurate environmental parameter data is always used for image formation, maintaining image quality while enabling continuous operation.
