Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robots require laborious effort due to friction between the roller and the floor, making them inefficient to push and pull.
Innovation Solution
A cleaning robot with a handle and a working assembly featuring a roller and a first driving mechanism, along with an adjustment mechanism that allows for adjustable rotational direction and speed of the roller, enabling effortless movement and cleaning via remote control or sliding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional cleaning robot is pushed and pulled manually, then the cleaning function is performed, but the friction between the roller and the floor makes it laborious
Solution Approach 1:
The patent replaces the manual mechanical pushing and pulling operation with an automated driving mechanism. The driving mechanism includes a driving wheel that can be controlled to move the cleaning robot forward or backward, substituting the manual force application with an automated motor-driven system. This eliminates the need for users to overcome friction by manually pushing or pulling the device.
Solution Approach 2:
The cleaning robot is equipped with self-propulsion capability through the driving mechanism, allowing it to move itself without external manual force. The system can autonomously or remotely controlled to move forward, backward, and change direction, making the device self-sufficient in terms of locomotion and eliminating the laborious manual operation.
2Ease of operation
If the cleaning robot is equipped with a driving mechanism for automated movement, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent combines the driving mechanism with the existing cleaning structure by integrating the driving wheel and motor system into the handle assembly. The driving mechanism shares space and structural elements with the handle, merging multiple functions (support, control, and propulsion) into a unified assembly rather than adding separate complex subsystems.
Solution Approach 2:
The handle assembly serves multiple functions: it provides structural support for the cleaning robot, houses the driving mechanism for automated movement, and includes control elements for operation. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving automated operation.
