Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitor devices for industrial environments become bulky and complex when trying to synchronously rotate three photoelectric devices, such as cameras and thermal imagers, due to the need for additional mechanisms, which complicates their design and increases their overall volume.
Innovation Solution
A compact monitor device design that integrates a transmission mechanism with a first angle rotation mechanism and a second angular rotation mechanism, using motors and gear systems to drive three photoelectric devices to rotate synchronously in orthogonal directions within a cylindrical casing, simplifying the structure and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three photoelectric devices are equipped in the monitor, then monitoring capabilities are enhanced, but the device complexity and overall volume increase
Solution Approach 1:
The patent combines three separate photoelectric devices (first photoelectric device in casing, second photoelectric device on transmission shaft, third photoelectric device on transmission shaft) into a single monitor device with a unified transmission mechanism. The first motor and second motor work together through gear mechanisms to synchronously control all three devices, merging multiple functions into one integrated system rather than using separate monitoring devices for each photoelectric sensor.
Solution Approach 2:
The transmission mechanism serves multiple functions simultaneously: it drives the casing to rotate horizontally (first direction) and drives the transmission shaft to rotate vertically (second direction), enabling all three photoelectric devices to achieve synchronized two-dimensional rotation. This multi-functional mechanism eliminates the need for separate drive systems for each device.
2Adaptability or versatility
If three photoelectric devices are equipped in the monitor, then monitoring capabilities are enhanced, but the overall volume becomes bulky
Solution Approach 1:
The patent places the second photoelectric device and third photoelectric device on the transmission shaft, which rotates within the casing. The transmission mechanism components (motors, gear mechanisms, transmission shaft) are nested within the casing's accommodating space. This nested arrangement allows three photoelectric devices to be compactly integrated without significantly increasing the external dimensions of the monitor device.
3Adaptability or versatility
If synchronized rotation of three photoelectric devices is achieved, then monitoring coverage is improved, but the transmission mechanism becomes complicated
Solution Approach 1:
The transmission mechanism is segmented into two independent but coordinated modules: the first angle rotation mechanism (with first motor and first gear mechanism) controls horizontal rotation of the casing, while the second angle rotation mechanism (with second motor and second gear mechanism) controls vertical rotation of the transmission shaft. This segmentation allows each module to be optimized independently while achieving synchronized three-dimensional positioning of all three photoelectric devices.
