Rotating Cleaning Assembly Design to Reduce Cliff Sensor Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning equipment often experiences reduced cliff sensor accuracy due to the side brush blocking the sensor's signal transmission and reception, leading to potential collisions with cliffs or stuck situations.
Innovation Solution
The design incorporates a cleaning assembly with a first component that passes through the gap between the cliff sensor and the surface while rotating, and a second component that does not, minimizing blockage and allowing multiple second components to improve dirt collection and cleaning quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the side brush protrudes outside the periphery of the base plate to collect dirt, then the cleaning ability is improved, but the cliff sensor is frequently blocked from transmitting or receiving optical signal, lowering detecting accuracy
Solution Approach 1:
The side brush is extracted from the base plate and integrated into the rotating cleaning assembly instead. This separates the dirt collection function from the base plate structure, allowing the brush to be contained within the housing perimeter while still performing its cleaning function through rotation.
Solution Approach 2:
The cleaning assembly adopts a rotating mechanism where the brush rotates along with the installing part. This dynamic structure allows the brush to sweep a larger area and collect dirt effectively without needing to protrude permanently outside the base plate, thereby preventing sensor blockage.
2Reliability
If the cliff sensor is disposed in front of the moving assembly to detect cliffs, then the safety is improved, but the side brush blocks the sensor frequently, making the cleaning equipment unable to detect cliffs accurately
Solution Approach 1:
The side brush function is extracted from the front area and integrated into the rotating cleaning assembly, clearing the path for the cliff sensor to operate without obstruction while maintaining safety detection capabilities.
Solution Approach 2:
The cleaning function is segmented into a separate rotating assembly with its own brush components, distinct from the base plate and sensor areas. This segmentation allows the cliff sensor to be positioned in front of the moving assembly without being blocked by brush bristles.
3Productivity
If multiple bristles are used in the side brush to improve cleaning coverage, then the cleaning quality is improved, but the frequency of blocking the cliff sensor increases
Solution Approach 1:
Multiple bristles are incorporated into a rotating cleaning assembly that spins at controlled speeds. This dynamic configuration allows the bristles to sweep across the surface and collect dirt effectively while the rotation keeps the brush contained within the housing perimeter, preventing sensor blockage.
Solution Approach 2:
The rotating cleaning assembly performs preliminary dirt collection and agitation before the main suction or collection mechanism operates. This preliminary action concentrates dirt in specific areas for more efficient collection while keeping the brush structure compact and contained.
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 significantly reduces the frequency of cliff sensor blockage, enhances detection accuracy, and allows for flexible design options to improve cleaning efficiency and quality.
Implementation Method 1
a cliff sensor, which is arranged on one of the housing, the moving assembly and the cleaning assembly, and the cliff sensor faces towards the surface to be cleaned
Implementation Method 2
the first component extends towards a periphery of the housing from the installing part, and rotates along with rotation of the installing part so as to stir dirt on the surface to be cleaned
Implementation Method 3
the side brush may collect the dirt on the surface to be cleaned (such as ground) into the trash bin, for that the trash bin can direct the dirt to the entrance of the trash bin while it is rotating
