Autonomous cleaning robot with two fixed lateral cleaning elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous cleaning robots struggle with effective suction of waste near obstacles due to the arrangement of lateral cleaning elements, which also compromises the compactness of the robot.
Innovation Solution
The autonomous cleaning robot features first and second lateral cleaning elements arranged on either side of the suction mouth, with their front edges located in front of and rear edges behind the suction mouth's front edge, allowing for efficient waste guidance and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first and second lateral cleaning elements are arranged in front of the suction mouth (as in prior art), then the structure is simplified and cleaning performance is good, but the suction mouth cannot be positioned close to the front edge of the main body, reducing effectiveness for waste near obstacles and compromising compactness
Solution Approach 1:
The patent repositions the lateral cleaning elements from a purely front-facing arrangement to a multi-dimensional configuration where they extend both in front of and behind the suction mouth's front edge. This spatial reorganization allows the suction mouth to be positioned closer to the robot's front edge while maintaining effective waste guidance, resolving the contradiction between structural simplicity and suction effectiveness.
Solution Approach 2:
The flexible cleaning parts are designed to dynamically adapt their position and shape based on waste location and robot movement, allowing them to effectively guide waste to the suction inlet regardless of the suction mouth's position relative to the front edge. This dynamic behavior maintains cleaning effectiveness while enabling more compact positioning.
2Device complexity
If the first and second lateral cleaning elements are arranged in front of the suction mouth (as in prior art), then the structure is simplified, but the robot's compactness is compromised
Solution Approach 1:
By extending the cleaning elements to span both in front of and behind the suction mouth, the design optimizes space utilization within the robot's body. This allows the suction mouth to be positioned more forward, reducing the overall volume required for effective cleaning operation while maintaining structural simplicity.
3Ease of manufacture
If the suction mouth is positioned far from the front edge of the main body (due to lateral cleaning element arrangement), then lateral cleaning elements can be arranged simply, but waste near obstacles cannot be effectively suctioned
Solution Approach 1:
The flexible cleaning parts dynamically respond to waste position and robot movement, effectively guiding waste to the suction inlet even when the suction mouth is positioned close to the front edge. This dynamic adaptation ensures reliable waste suction near obstacles while maintaining simple lateral cleaning element arrangement.
Solution Approach 2:
The flexible cleaning parts can deform and adapt their shape to effectively guide waste to the suction inlet, ensuring reliable suction performance even with the optimized compact positioning of the suction mouth near the front edge.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration brings the suction mouth closer to the front edge of the robot, ensuring efficient suction of waste near obstacles and enhancing cleaning performance by maintaining a seal on either side of the suction inlet.
Implementation Method 1
the first lateral cleaning element comprising a first cleaning part which is flexible and the second lateral cleaning element comprising a second cleaning part which is flexible, the first and second cleaning portions being configured to direct waste, which comes into contact with the first and second cleaning portions when the autonomous cleaning robot moves in the main direction of movement, towards the suction inlet
Implementation Method 2
a suction inlet opening into the lower face of the main body and extending transversely to a main direction of movement of the autonomous cleaning robot, and a suction chamber fluidly connected to the suction inlet
