Solution Overview

Problem

Existing on-site monitoring systems struggle to appropriately set and maintain the area to be monitored, especially in dynamic work environments where obstacles and work areas frequently change.

Innovation Solution

An on-site monitoring apparatus comprising a warning device, a partition object detection device, a boundary input device, and a control device that determines whether boundaries are arranged correctly with partition objects, issuing warnings for unarranged boundaries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed monitoring area is set in advance, then the monitoring system can operate continuously, but it cannot adapt to changing work environments and obstacles

Engineering Contradiction:

Improveadaptability to changing work environmentVSAvoidcomplexity of monitoring area setting

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The monitoring area is no longer a fixed static region but dynamically adjusts based on real-time detection of partition objects. The control device continuously updates the monitoring area boundaries according to the positions detected by the partition object detection device, enabling the system to adapt to changing work environments without manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system automatically detects partition objects and self-adjusts the monitoring area without requiring manual intervention. The control device receives position information from the detection device and autonomously determines the appropriate monitoring area, making the system self-configuring and adaptable to environmental changes.

Inventive Principle:

Principle #25Self-service

2Reliability

If the monitoring area is expanded to cover more areas, then more obstacles can be detected, but work interruptions increase due to false alarms in areas without partition objects

Engineering Contradiction:

Improveaccuracy of obstacle detectionVSAvoidwork interruption frequency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The monitoring area is not uniformly applied across all spaces but is locally concentrated only in regions where partition objects are detected. The control device adjusts the monitoring area to match the actual distribution of partition objects, ensuring detection coverage is precisely where needed and avoiding false alarms in areas without partitions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of monitoring the entire potential work area, the system applies monitoring only to the necessary partial area defined by partition object positions. This selective monitoring approach maintains detection accuracy while minimizing unnecessary monitoring that would cause false alarms and work interruptions.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If partition objects are manually arranged at all boundaries, then complete coverage is achieved, but the system cannot handle cases where boundaries change or objects are misplaced

Engineering Contradiction:

Improvecompleteness of boundary coverageVSAvoidresponse to boundary changes

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The partition object detection device continuously monitors the positions of partition objects, providing feedback to the control device. When objects are misplaced or boundaries change, the detection device identifies these changes and the control device adjusts the monitoring area accordingly, enabling the system to respond to and adapt to boundary changes automatically.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The manual mechanical arrangement and verification of partition objects is replaced by an automated detection system. The partition object detection device uses sensing technology to automatically identify partition object positions, eliminating the need for manual verification and enabling real-time adaptation to boundary changes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Provided is an on-site monitoring apparatus and an on-site monitoring system that can appropriately set an area to be subjected to on-site monitoring. The on-site monitoring apparatus includes warning devices 104 and 309 that output a warning, peripheral object detection devices 102 and 307 that detect a position of a partition object 512, work area input devices 101 and 305 that receive an input of information indicating boundaries AB and BC to be arranged with a partition object, and control devices 103 and 308. The control devices 103 and 308 includes operation environment determination sections 107 and 312 that determine, for each boundary, whether the boundary is an arranged boundary where the partition object 512 is arranged at a position corresponding to the boundary or an unarranged boundary where the partition object 512 is not arranged at a position corresponding to the boundary, and warning content determination sections 108 and 313 that output a warning by the warning devices 104 and 309 when at least one unarranged boundary is present.
