Cleaning Robot Lifting Structure for Spill-Free Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robots require user intervention for transportation after completion of tasks, as they are not designed for easy carrying due to their design and functionality.
Innovation Solution
A cleaning robot equipped with a lifting device that allows the robot body to be lifted and rotated, featuring a collecting device for debris and a cleaning device at the bottom, enabling convenient carrying by tilting the inlet upwards or perpendicular to the ground, along with a power assembly for pneumatic suction and a driving mechanism for rotating the lifting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning robot is designed with a fixed structure for effective cleaning operation, then cleaning performance is improved, but ease of carrying deteriorates
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotatable lifting device that enables the robot body to change its orientation. The lifting device includes a rotating component that can pivot the entire robot body to a tilted position during carrying, transforming the static structure into a dynamic one that adapts to different operational states (cleaning vs. carrying).
Solution Approach 2:
The patent employs dimensionality change by adding a rotational degree of freedom to the robot system. The lifting device introduces a new dimensional movement (rotation/pivoting) that allows the robot to transition between horizontal cleaning posture and tilted carrying posture, effectively utilizing angular displacement as an additional dimension for solving the carrying problem.
2Ease of operation
If the robot body is lifted during transportation, then ease of carrying is improved, but debris may fall out from the collecting device
Solution Approach 1:
The patent applies preliminary action by designing the inlet of the collecting device to be tiltable or perpendicular to the ground when the robot is lifted. This pre-configured orientation ensures that debris remains contained within the collecting device during the lifting and carrying operations, preventing spillage before it can occur.
Solution Approach 2:
The lifting device's rotational capability dynamically adjusts the robot body's orientation during carrying, tilting the inlet upwards or making it perpendicular to the ground. This dynamic repositioning maintains debris containment while enabling easy carrying, resolving the contradiction between ease of carrying and debris containment reliability.
3Ease of operation
If a lifting device is added to enable easy carrying, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The lifting device is designed with multi-functionality, serving both as a carrying assistance mechanism and as a means to adjust the robot body's orientation for proper inlet positioning during transport. This universal design allows a single added component to address multiple requirements (ease of carrying and debris containment), thereby reducing the overall complexity increase.
4Reliability
If the inlet is tilted upwards during lifting, then debris containment is improved, but structural complexity increases
Solution Approach 1:
The patent merges the inlet orientation adjustment with the overall robot body tilting mechanism. Instead of adding a separate adjustment mechanism for the inlet, the design combines the inlet's angular adjustment with the lifting device's rotation, allowing both functions to be achieved through a unified structural arrangement that minimizes additional complexity.
