Bidirectional mobile cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bionic cleaning robots are inefficient as they cannot effectively clean the ground when moving in reverse due to the garbage scraper lip scooting garbage instead of collecting it, leading to incomplete cleaning and reduced efficiency.
Innovation Solution
A bidirectional mobile cleaning device with oppositely-rotating rolling members at the ends of a garbage collection box, allowing for thorough cleaning in both forward and backward motion by controlling the speed difference between the rolling members, and incorporating brush members and sewage recovery systems to enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single forward cleaning direction is used, then the structure is simple, but cleaning efficiency deteriorates when moving in reverse
Solution Approach 1:
The single cleaning roller is segmented into two oppositely rotating rolling members positioned at both ends of the garbage collection box. Each rolling member independently rotates in opposite directions to collect garbage from both forward and backward motion directions, enabling bidirectional cleaning capability without requiring separate cleaning systems for each direction.
Solution Approach 2:
The rolling members serve multiple functions: they act as cleaning members to collect garbage, simultaneously function as driving members to propel the device forward or backward through speed differential control, and enable bidirectional movement. This multi-functionality resolves the contradiction by making the cleaning system adaptable to both forward and reverse motion without adding separate dedicated systems.
2Productivity
If a garbage scraper lip is used for reverse motion, then the structure remains simple, but cleaning effectiveness deteriorates due to garbage being scooted away
Solution Approach 1:
Instead of using a garbage scraper lip that pushes garbage backward during reverse motion (which causes garbage to be scooted away), the patent inverts the approach by using a rolling member that rotates in the opposite direction. This inverted rotation direction allows the rolling member to effectively scoop and collect garbage even when the device moves in reverse, transforming the harmful scooting effect into a useful cleaning action.
3Productivity
If oppositely-rotating rolling members are added for bidirectional cleaning, then cleaning efficiency in both directions is improved, but device complexity increases
Solution Approach 1:
The patent merges the cleaning function and driving function into a single integrated system. The oppositely rotating rolling members simultaneously perform garbage collection and device propulsion, eliminating the need for separate cleaning rollers and drive wheels. This merging reduces overall device complexity despite adding bidirectional cleaning capability, as multiple functions are consolidated into unified components.
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
The device ensures thorough cleaning in both directions, improving efficiency by effectively collecting garbage and sewage regardless of the direction of movement, and preventing secondary pollution through sewage recovery.
Implementation Method 1
The first rolling member and the second rolling member nib against the ground
Implementation Method 2
The first rolling member and the second rolling member nib against the ground. The rotation direction of the first rotting member and the second rolling member are opposite each other. By controlling the difference in rotation speed between the two rolling members, the device can be controlled to move forward or backward.

AI summary
The disclosure relates to a bidirectional mobile cleaning device comprising a garbage collection box, a first rolling member disposed at one end of the garbage collection box, and a second rolling member disposed at the other end of the garbage collection box. The first rolling member rotates to collect and adsorb garbage and sewage on the ground and feed it into the garbage collection box. The second rolling member rotates in a direction opposite to the direction with which the first rolling member rotates to collect and absorb garbage and sewage on the ground and feed it into the garbage collection box. The bidirectional mobile cleaning device is driven to move based on a speed difference between the first and second rolling members.
