Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive wire connected to a power supply facility is used to define the working area, then the working robot can recognize the area through magnetic field detection, but the operation is interrupted when the power supply facility breaks down or experiences blackout
Solution Approach 1:
The patent extracts the area definition function from the power supply facility by using a separate non-energization wire. This wire is dedicated solely to defining the working area boundary and can be detected by the robot through its wire detector, independent of the power supply facility's operational status. This separation eliminates the dependency between power supply and area definition functions.
Solution Approach 2:
The non-energization wire acts as an intermediary element between the power supply facility and the working robot. It transmits area boundary information to the robot without requiring electrical power, serving as a communication medium that is independent of the power supply system. This intermediary enables the robot to receive area definition information even when the power supply facility is non-operational.
2Reliability
If a conductive wire is used to partition the working area, then the area boundary can be detected via magnetic field, but the system fails when the wire is not energized or the power facility malfunctions
Solution Approach 1:
The patent employs a non-energization wire that does not require continuous power supply to maintain its area-defining function. Unlike the conductive wire that needs constant electrical energy to generate a detectable magnetic field, the non-energization wire provides passive detection capability, eliminating the need for ongoing energy consumption to maintain area boundary visibility.
3Ease of operation
If the working robot relies on magnetic field detection from an energized wire, then area boundary detection is possible, but operation is disrupted when electricity conduction is broken
Solution Approach 1:
The patent extracts the area boundary detection function from the power-dependent magnetic field system and implements it through a separate non-energization wire detection system. The wire detector on the robot directly detects the physical presence of the non-energization wire, independent of any electrical conduction, thereby providing stable detection that is not disrupted by electricity conduction issues.
