Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the robot cleaner is equipped with a battery and charging device for autonomous operation, then the robot cleaner can move and clean autonomously, but the robot cleaner requires accurate docking guidance to ensure effective charging
Solution Approach 1:
The patent introduces an induction signal guide member as an intermediary element between the induction signal generating unit and the robot cleaner. This guide member shapes and directs the induction signal to form a directional path, mediating the guidance process to improve docking accuracy while maintaining autonomous operation capability.
2Productivity
If the charging terminal and power supply terminal are connected for effective charging, then power can be transferred to charge the battery, but the contact force between terminals must be increased to maintain tight contact
Solution Approach 1:
The patent employs a resilient terminal supporting member that provides elastic support to the charging terminal. This dynamic element automatically adjusts to maintain optimal contact force between the charging terminal and power supply terminal, ensuring reliable electrical connection for effective charging while accommodating minor positioning variations.
3Ease of operation
If the induction signal is transmitted to guide the robot cleaner back to the charging device, then the robot cleaner can return for recharging, but the linearity of the induction signal must be improved to enhance docking performance
Solution Approach 1:
The induction signal guide member acts as a mediator that shapes and directs the induction signal transmission. It creates a focused signal path with improved linearity, enabling the robot cleaner to accurately follow the signal gradient and dock precisely with the charging device.
Solution Approach 2:
The guide member modifies the physical parameters of the induction signal transmission by confining and directing the signal fields. This changes the signal distribution pattern from diffuse to focused, improving linearity and enabling more precise navigation and docking.
