Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In unmanned factories, robot devices face challenges in monitoring their surroundings effectively due to limited sensor capabilities, leading to potential blind spots and increased manufacturing costs, which can result in safety accidents.
Innovation Solution
An electronic device that communicates with multiple robot devices to identify target devices based on operation information, location, and hazardous region data, and controls other robot devices to monitor these targets, using sensors to gather data on their environment and transmit commands to ensure safe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of sensors that a robot device must have increases, then the monitoring capability of the surrounding environment is improved, but the manufacturing cost of the robot device increases rapidly
Solution Approach 1:
Multiple robot devices are merged into a cooperative system where they share monitoring responsibilities. Each robot's sensors monitor not only its own surroundings but also the surroundings of other robots in the group, effectively combining the monitoring capabilities of multiple devices to reduce the sensor burden on individual robots.
Solution Approach 2:
The sensor system is designed to serve multiple functions: each robot's sensors monitor both its own operational environment and the environments of other robots in the cooperative group, making the same sensors perform multiple monitoring tasks simultaneously.
2Productivity
If a robot device operates autonomously, then the productivity is improved, but the safety risk increases due to potential blind spots in monitoring
Solution Approach 1:
A feedback mechanism is established where robot devices continuously exchange monitoring data about each other's operations and environments. This real-time feedback allows the system to identify and respond to safety risks that individual robots cannot detect alone, enabling autonomous operation with enhanced safety.
Solution Approach 2:
The safety monitoring system merges the observational capabilities of multiple robots, creating a collective awareness that covers blind spots of individual devices. This combined monitoring approach maintains autonomous productivity while reducing safety risks through cooperative surveillance.
3Area of stationary object
If the number of sensors that a robot device must have increases, then the monitoring coverage of the surrounding environment is improved, but the device complexity increases
Solution Approach 1:
The monitoring coverage of multiple robot devices is merged through cooperative operation. Instead of each robot requiring complete monitoring coverage with numerous sensors, the system achieves comprehensive coverage by combining the sensor data from multiple robots, each with fewer sensors.
Solution Approach 2:
The monitoring approach transitions from a single-robot perspective to a multi-robot system perspective, adding the dimension of spatial distribution. Robots positioned at different locations provide complementary views of the environment, achieving comprehensive coverage through spatial diversity rather than sensor quantity.
