Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-functional robots face stability issues when encountering uneven surfaces due to shifted center of gravity, leading to potential sticking or water tank overflow, which can cause electrical short circuits and pollution.
Innovation Solution
The implementation of floating supporting mechanisms that extend and contract to maintain the robot's stability on uneven ground, with driving wheels on either side and a driven wheel at the front or rear, ensuring the machine body remains parallel to the walking plane, and incorporating a cleaning cloth assembly for enhanced wiping functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional modules are added to create a multi-functional robot, then the robot's functionality is improved, but the center of gravity shifts to the middle portion causing the robot to jolt on uneven surfaces
Solution Approach 1:
The patent applies the dynamics principle by making the supporting end movable through floating supporting mechanisms. These mechanisms allow the supporting end to dynamically adjust its position and orientation in response to uneven surfaces, enabling the robot to maintain stability despite having functional modules that shift the center of gravity to the middle portion.
2Adaptability or versatility
If the robot encounters a pit or step, then the center of gravity shifts backwards, but the robot gets stuck to the pit or step
Solution Approach 1:
The floating supporting mechanisms provide dynamic adjustment capability that allows the supporting end to move independently when encountering obstacles. This dynamic movement prevents the robot from getting stuck by accommodating the center of gravity shift without compromising walking reliability.
3Adaptability or versatility
If the robot has a water tank for humidification, then the robot can perform humidification function, but the robot jolts on uneven surfaces causing water tank overflow
Solution Approach 1:
The floating supporting mechanisms enable the supporting end to dynamically compensate for jolts caused by uneven surfaces. This dynamic compensation keeps the water tank stable during humidification operations, preventing overflow while maintaining the humidification function.
4Stability of the object's composition
If floating supporting mechanisms are added to improve walking stability, then the robot can handle uneven ground, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the robot into distinct functional modules including the self-moving robot and detachable functional modules. The floating supporting mechanisms are integrated as separate components that can be combined with the modular structure, managing device complexity through systematic segmentation.
Solution Approach 2:
The floating supporting mechanisms serve multiple functions: they maintain walking stability on uneven surfaces, prevent the robot from getting stuck on obstacles, and stabilize the water tank during humidification operations. This multi-functionality reduces the need for additional specialized components, managing overall device complexity.

AI summary
A combined robot includes a self-moving robot and a functional module, in which the functional module is detachably combined into the self-moving robot through a connecting piece. Driving wheels and a driven wheel are disposed at a bottom of a machine body of the self-moving robot. By taking an advancing direction when the self-moving robot operates as a forward direction, the driving wheels are located on a left side and a right side of the bottom of the machine body. The driven wheel is located at a front end or a rear end of the bottom of the machine body. A control center is disposed in the combined robot and controls the combined robot to operate. One end away from the driven wheel of the bottom of the machine body of the self-moving robot is a supporting end, and floating supporting mechanisms are disposed at the supporting end.
