Cleaning Robot Safety Guard Connector with Connection State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning robots used for vertical surfaces often rely on safety ropes for prevention from falling, but the connection state of these ropes is not detected, leading to potential safety risks due to loose connections.
Innovation Solution
A cleaning system with a self-propelled robot and a safety guard connector that includes a securing connector assembly with a detector to monitor its connection state, allowing the robot to enter a safe activation state only when properly connected, thereby preventing falls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety rope connection system is used to prevent falling, then safety is improved, but the connection state cannot be detected leading to potential safety risks
Solution Approach 1:
The patent implements a feedback mechanism by introducing a detector assembly that continuously monitors the connection state between the safety rope and the cleaning robot. The detector provides real-time feedback signals to the control unit, enabling the system to detect when the safety rope is properly connected or disconnected, thus resolving the information loss problem while maintaining safety.
Solution Approach 2:
The patent introduces an intermediary detection mechanism (detector assembly with detection element) that mediates between the safety rope connection and the control system. This intermediary component translates the physical connection state into detectable signals, allowing the control unit to monitor safety rope status without directly interfering with the safety function.
2Reliability
If a detector assembly is added to monitor connection state, then safety monitoring is improved, but device complexity increases
Solution Approach 1:
The patent merges the detector assembly with the existing securing connector assembly structure. The detection element is integrated into the connector components that are already part of the safety system, allowing the monitoring function to be added without significantly increasing overall device complexity. The detector utilizes existing structural elements as mounting points and reference features.
