Robot Cleaner Dust Bin Detection for Filtration Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners lack a mechanism to detect if the foreign material storage unit is mounted, leading to potential operation without filtration and dust accumulation or dispersal, creating unsanitary conditions.
Innovation Solution
Incorporating a detection unit and a foreign material cover that can be selectively coupled, with a hook structure and push part to ensure the foreign material storage unit is properly seated and the cover is closed, preventing operation without the storage unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the foreign material storage unit is disposed inside the main body without detection mechanism, then the structure is simple and easy to manufacture, but the cleaner may operate without proper filtration causing dust accumulation and unsanitary conditions
Solution Approach 1:
A detection unit is provided to detect whether the foreign material storage unit is properly disposed inside the main body. The control unit receives the detection signal and controls the cleaner to operate only when the storage unit is properly disposed, preventing operation without proper filtration while maintaining a relatively simple structure.
Solution Approach 2:
The detection unit automatically detects the presence of the foreign material storage unit and sends signals to the control unit, which then automatically controls the cleaner's operation status. This self-service mechanism ensures proper filtration without requiring complex manual verification systems.
2Volume of moving object
If the foreign material storage unit is disposed inside the main body, then the structure is compact, but the user cannot know whether the storage unit is installed leading to potential operation without filtration
Solution Approach 1:
The detection unit provides feedback information about the mounting status of the foreign material storage unit to the control unit, which then controls the operation of the cleaner. This feedback mechanism ensures that the cleaner only operates when the storage unit is properly installed, preventing dust accumulation while maintaining a compact structure.
Solution Approach 2:
The patent replaces manual verification of the storage unit's installation status with an automated detection unit that uses electrical or electronic sensing mechanisms. This substitution provides reliable mounting status information without requiring the user to physically check the installation, maintaining compactness while preventing information loss.
3Ease of operation
If the cleaner operates without detecting the foreign material storage unit, then the ease of operation is high, but dust may accumulate or fly to the outside causing unsanitary environment
Solution Approach 1:
The detection unit continuously monitors whether the foreign material storage unit is properly disposed and provides feedback to the control unit. The control unit uses this feedback to control the cleaner's operation, ensuring that the cleaner only operates when proper filtration is in place, thus preventing dust accumulation and dispersal while maintaining ease of operation through automated control.
Solution Approach 2:
The detection unit and control unit work together to prevent the cleaner from operating in a state where the foreign material storage unit is not properly disposed. By detecting the mounting status beforehand and controlling the operation accordingly, the system prevents dust accumulation and unsanitary conditions before they can occur, rather than addressing them after the fact.

AI summary
Provided is a robot cleaner, and more particularly to a robot cleaner which detest whether a foreign material storage unit is separated. The robot cleaner includes a main body including a suction motor, a foreign material storage unit separably disposed within the main body, the foreign material storage unit storing foreign materials contained in sucked air, a foreign material cover for selectively shielding one side of the foreign material storage unit, and a detection unit for detecting whether the foreign material cover is opened.
