Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brushrolls for robot vacuum cleaners have high manufacturing costs and low efficiency due to complex process requirements, and they often result in large vibrations and deformation during operation.
Innovation Solution
A brushroll design featuring a first and second mirror-symmetrical roller with mounting grooves and brush members, connected by a snap-fitting mechanism, which reduces manufacturing costs and facilitates efficient assembly and operation by preventing relative rotation between the rollers.

Engineering Contradiction Analysis
1Area of stationary object
If a single long roller brush is used, then the cleaning coverage is improved, but the vibration and deformation during operation increase
Solution Approach 1:
The single long roller brush is divided into multiple roller brush units of appropriate length. Each unit is independently supported by the robot body, eliminating the vibration and deformation problems of long rollers while maintaining extensive cleaning coverage through multiple units working together.
Solution Approach 2:
Instead of extending the roller length in one dimension (which causes vibration), the solution transitions to arranging multiple rollers in a different spatial configuration, with each roller supported at multiple points along its length, distributing the mechanical stress and preventing deformation.
2Ease of operation
If plant fibers with high process requirements are used, then the cleaning ability is improved, but the manufacturing cost increases and efficiency decreases
Solution Approach 1:
The patent replaces expensive, difficult-to-process plant fibers with more economical materials that have lower manufacturing requirements. The focus shifts to optimizing the mechanical structure and arrangement of brush units to achieve effective cleaning without relying on high-cost materials with stringent processing needs.
Solution Approach 2:
The invention changes the material parameters from high-performance plant fibers to more readily manufacturable materials, compensating for the material downgrade through improved structural design, brush arrangement, and mechanical optimization to maintain cleaning effectiveness.
3Area of stationary object
If multiple roller brushes are set with staggered arrangement, then the cleaning coverage is improved, but the device complexity increases
Solution Approach 1:
Multiple roller brush units are designed with standardized structures and mounting mechanisms, allowing them to perform identical cleaning functions. This modular universality simplifies the overall system design compared to complex differentiated structures, while still achieving extended cleaning coverage through their coordinated arrangement.
