Solution Overview
Problem
Existing robot cleaners face challenges with suction force reduction, brush roller separation issues, increased collision probability of the suction unit with obstacles, blind spots in sensing, and inconvenient HEPA filter replacement.
Innovation Solution
A robot cleaner design featuring a suction unit protruding from the body with integrated sensing parts, a dust container system with improved assembly and capacity, and a HEPA filter replacement mechanism that allows for easy access without disassembling the cleaner body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the suction unit is disposed to protrude from the cleaner body, then the suction force is improved, but the probability of collision with obstacles increases
Solution Approach 1:
The suction unit is configured to be movable relative to the cleaner body, transitioning between a protruding state during cleaning operations to maximize suction force and a retracted state during navigation to minimize collision probability. This dynamic adjustment allows the system to optimize performance based on operational context.
2Quantity of substance
If the dust container capacity is increased, then the dust collection capability is improved, but the height of the cleaner body increases
Solution Approach 1:
The dust container is designed to extend in the horizontal direction rather than increasing vertical height, utilizing the lateral space within the cleaner body to maximize dust storage capacity while maintaining a compact profile suitable for navigating under furniture.
Solution Approach 2:
The dust container is nested within the cleaner body structure, with the HEPA filter and other components arranged in a compact, space-efficient configuration that maximizes internal volume utilization without increasing external dimensions.
3Reliability
If the HEPA filter is integrated into the cleaner body, then the filtration function is improved, but the replacement convenience deteriorates
Solution Approach 1:
The dust container assembly including the HEPA filter is designed as a separable module that can be easily detached from the cleaner body without requiring disassembly of the main structure. This modular design maintains effective filtration while enabling convenient filter replacement by the user.
Solution Approach 2:
The dust container is equipped with quick-release latches or snap-fit mechanisms that are pre-configured for tool-free removal, allowing users to access and replace the HEPA filter quickly without requiring technical expertise or special tools.
