Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a monitoring device using invisible light such as infrared light is used, then the monitoring function is provided, but it is difficult to check whether the monitoring device is installed so as to be able to monitor an intended area
Solution Approach 1:
The patent applies the principle of color changes by causing the monitoring region to be displayed in a specific color (e.g., red or green) on the display device. This allows the installer to visually identify the monitoring region and verify correct installation without needing to see invisible infrared light. The color-coded display provides immediate visual feedback about the monitoring coverage area.
2Ease of operation
If a synthesized image is created by incorporating a boundary image and a captured image to display the monitoring region, then the monitoring region can be visually grasped, but the system becomes complicated with GPS and gyro sensors
Solution Approach 1:
The patent extracts and eliminates the unnecessary GPS and gyro sensor components from the system. Instead of using complex location and orientation sensing, the invention uses a simpler approach where the monitoring region is directly displayed on the display device based on the monitoring device's field of view and preset region data, achieving visualization without the added complexity of multiple sensors and synthesized image processing.
3Adaptability or versatility
If a monitoring region is set up for each monitoring device by a worker at the installing site, then the monitoring region fits the installing site, but it is cumbersome and difficult to set up the monitoring region effectively
Solution Approach 1:
The patent applies preliminary action by allowing the monitoring region to be preset and stored in advance before installation. The region data is saved in the storage unit, and during installation, the monitoring device simply retrieves and displays this pre-configured region information. This eliminates the need for workers to manually set up and adjust monitoring regions at the installation site, significantly reducing setup time while maintaining adaptability to different installing sites.

AI summary
Monitoring system includes: a light projecting and receiving unit including an emitting section to emit a light flux, a scanning section to make the light flux scan within a monitoring space, and a light receiving section to receive a light flux reflected from an object within the monitoring space; a processing section to measure a distance to the object by processing signals from the light projecting and receiving unit and to output a measurement point marker group provided with three-dimensional distance information for each measurement point; a user interface that sets a monitoring region in a virtual space by an operation of a user; and a display device that, when the monitoring region has been set via the user interface, displays the set monitoring region together with the measurement point marker group, wherein the processing section outputs an alarm signal when an object invades within the monitoring region during monitoring.
