Remote Control Vibration Feedback for Working Tool Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-place cleaning remote-controlled robots fail to reliably notify operators of contact between the cleaning tool and the target surface, making it difficult to determine if the cleaning tool is pressed against the surface effectively.
Innovation Solution
A remote-operated working device equipped with a movement controller, a working unit, a first detector for contact detection, and a communicator that transmits a signal to vibrate the remote control when contact is detected, ensuring the operator is notified of contact between the working unit and the work target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual monitoring is used to confirm contact between cleaning tool and target surface, then operator can observe cleaning process, but notification reliability is insufficient when visual cues are unavailable
Solution Approach 1:
A vibration notification device acts as an intermediary between the contact detection sensor and the operator. When the sensor detects contact between the cleaning tool and target surface, it triggers vibration feedback through the remote control, providing reliable non-visual notification to the operator who may not have direct line of sight to the cleaning process.
Solution Approach 2:
The patent replaces reliance on visual mechanical observation with an electronic sensing and vibration feedback system. The contact sensor electronically detects contact forces, and the vibration motor converts this detection into tactile feedback, substituting the need for visual confirmation with an automated electromechanical notification system.
2Reliability
If contact detection system is added to notify operator, then notification reliability improves, but device complexity increases
Solution Approach 1:
The system implements a closed-loop feedback mechanism where the contact sensor continuously monitors the interface between the cleaning tool and target surface, and immediately feeds this information back to the operator through vibration notification. This automatic feedback loop ensures reliable contact detection without requiring complex manual monitoring systems.
Solution Approach 2:
The contact detection system is self-activating - when contact occurs, the sensor automatically triggers the vibration notification without requiring additional operator intervention or complex control logic. The system serves itself by autonomously detecting and communicating contact status.

Function Achieved in This Case
The solution allows for certain notification of contact between the working unit and the work target, enhancing the operator's ability to confirm contact without visual cues, thereby improving the reliability of the cleaning process.
Implementation Method 1
a communicator that transmits a signal for vibrating the remote control to the remote control in a case where contact between the working unit and the work target is detected by the first detector
