Cleaning device and auxiliary device for cleaning with a basic unit of the cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices with attachments lack bidirectional communication between the attachment and the base unit, limiting the ability of the attachment to output control commands and receive information from the base unit, which restricts dynamic control of operating parameters such as fan output.
Innovation Solution
The attachment is equipped with an attachment control device that can transmit an ID code and receive information from the base unit, allowing it to output control commands, including instructions for operating parameters like fan power, through a bidirectional communication interface, enabling the attachment to control the base unit's operating parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the attachment is equipped with control capabilities to dynamically adjust base unit operating parameters, then cleaning efficiency and adaptability are improved, but device complexity increases
Solution Approach 1:
The bidirectional communication interface serves multiple functions: it transmits identification codes from attachment to base unit, sends surface type information, and delivers control commands for operating parameter adjustment. This multi-functionality reduces the need for separate dedicated systems for each communication task, thereby improving adaptability while limiting the increase in overall system complexity.
Solution Approach 2:
The system implements feedback loops where the attachment receives information from the base unit about current operating parameters and surface conditions, processes this information, and sends back control commands to adjust parameters like fan power. This feedback mechanism enables dynamic adaptation to different cleaning scenarios without requiring complete system redesign for each situation.
2Productivity
If real-time communication between attachment and base unit is implemented, then dynamic control of operating parameters is enabled, but information processing requirements increase
Solution Approach 1:
The control logic and information processing functions are extracted from the base unit and placed in the attachment, which has direct contact with the cleaning surface. This allows the attachment to independently process surface type information and generate appropriate control commands, reducing the information processing burden on the base unit while maintaining real-time control capabilities that improve cleaning efficiency.
Solution Approach 2:
The attachment performs preliminary identification of surface types and pre-processing of cleaning requirements before transmitting control commands to the base unit. This preliminary action reduces the amount of raw information that needs to be processed in real-time by the base unit, as the attachment has already analyzed surface conditions and determined the appropriate cleaning parameters in advance.
3Ease of operation
If the attachment can transmit control commands to the base unit, then operating parameter control is improved, but reliability requirements for communication increase
Solution Approach 1:
The bidirectional communication interface acts as an intermediary between the attachment control unit and the base unit control system. It provides a standardized protocol for transmitting control commands, ensuring that signals are properly formatted and transmitted reliably. This intermediary layer simplifies the control operation for the user while maintaining high reliability through standardized communication procedures and error handling mechanisms.
