Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot cleaners face issues with reduced suction force, inability to separate brush rollers, increased collision probability of the suction unit with obstacles, blind spots in sensing, and inconvenient HEPA filter replacement due to complex disassembly requirements.
Innovation Solution
A robot cleaner design featuring a suction unit protruding from the cleaner body with cover members to prevent collisions, a sensing unit that overlaps with the suction unit for obstacle detection, and a dust container with improved assembly and filter access, allowing for easy maintenance and enhanced navigation capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the suction unit protrudes from the cleaner body, then the suction force is improved, but the collision probability with obstacles increases
Solution Approach 1:
The suction unit is divided into a modular component that can be detached from the cleaner body. This segmentation allows the suction unit to protrude for better cleaning performance while enabling easy removal to avoid collision damage and facilitate maintenance of the brush roller and other components.
Solution Approach 2:
The suction unit is designed with dynamic positioning capability, allowing it to protrude during cleaning operations and be retracted or removed when collision risk is detected or during maintenance periods. This dynamic adjustment optimizes both cleaning effectiveness and collision avoidance.
2Power
If the suction unit protrudes from the cleaner body, then the suction force is improved, but the suction unit is located in a blind spot of the sensing unit
Solution Approach 1:
The sensing unit and suction unit are merged or closely integrated in design, with the sensing unit positioned to overlap with the suction unit's working area. This combination ensures that obstacles in the suction unit's blind spot are detected, allowing the controller to adjust the suction unit's position or operation accordingly.
Solution Approach 2:
The sensing unit provides real-time feedback about obstacles in the suction unit's operational area. The controller processes this feedback and adjusts the suction unit's position or activation state to avoid collisions and maintain effective cleaning coverage, eliminating the blind spot issue.
3Object-affected harmful factors
If the HEPA filter is integrated into the cleaner body, then the filtration is effective, but the filter replacement requires complex disassembly
Solution Approach 1:
The HEPA filter is integrated into the detachable suction unit rather than being permanently fixed in the cleaner body. This segmentation allows the filter to maintain its filtration effectiveness while enabling easy access and replacement by simply detaching the suction unit, eliminating the need for complex disassembly.
4Device complexity
If the brush roller is built into the cleaner body, then the structure is compact, but the brush roller separation is impossible
Solution Approach 1:
The brush roller is integrated into the detachable suction unit module. This segmentation maintains a compact overall structure while enabling easy separation and removal of the brush roller by simply detaching the suction unit from the cleaner body, facilitating maintenance without complex disassembly.
