Cleaning Robot Dust Box Front Placement for Increased Storage Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots have limited dust box volume and storage space due to the rear placement of the dust box, which is affected by other main components, leading to reduced cleaning efficiency and user experience.
Innovation Solution
The dust box is positioned in front of the rolling brush assembly, allowing for increased volume and storage space, and the center of gravity is adjusted by placing the battery and mopping assembly strategically to improve stability and reduce shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the dust box is arranged on the rear side of the rolling brush assembly, then the structure is compact, but the dust box volume and storage space are limited
Solution Approach 1:
The dust box is inverted from its conventional rear-side placement to a front-side placement relative to the rolling brush assembly. This inversion allows the dust box to occupy the front portion of the body where space is otherwise unused, thereby increasing dust box volume without complicating the overall structure.
Solution Approach 2:
The dust box is positioned in the front portion of the body along the advancing direction, utilizing three-dimensional space optimization. This spatial reconfiguration allows the dust box to extend forward without interfering with the rolling brush assembly or other components, effectively increasing storage capacity within the same overall footprint.
2Volume of moving object
If the dust box volume is increased, then storage space is improved, but the center of gravity shifts affecting stability
Solution Approach 1:
The battery is strategically positioned to serve as a counterweight that balances the forward shift in center of gravity caused by the front-mounted dust box. By placing the heavy battery in the rear portion of the body, the system maintains proper weight distribution and stability despite the altered component layout.
Solution Approach 2:
The center of gravity position is adjusted by changing the spatial distribution of components. The dust box is moved forward while the battery position is optimized to shift the overall center of gravity to an optimal location that maintains stability. This parameter optimization ensures the robot operates smoothly without excessive shaking or instability.
3Ease of operation
If the mopping assembly is placed at the rear portion, then it can effectively clean the ground, but it may cause shaking during operation
Solution Approach 1:
The battery serves as a counterweight that stabilizes the robot during mopping operations. By positioning the heavy battery in the rear portion near the mopping assembly, the system counteracts the shaking and vibrations generated during mopping, thereby maintaining both effectiveness and stability.
Solution Approach 2:
The center of gravity is optimized to a position that balances the rearward placement of the mopping assembly. By adjusting the spatial parameters of heavy components like the battery, the system achieves a center of gravity location that minimizes shaking during mopping while preserving cleaning effectiveness.
