Cleaner having detachable or separable control module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless cleaners face challenges in efficiently managing power supply and user convenience due to the integration of the control module with the main body, which limits the ability to replace or maintain components like the filter housing without separating the control module, affecting suction efficiency and battery life.
Innovation Solution
A cleaner design where the control module is detachable and separable from the main body, allowing for separate attachment and detachment in various directions, enabling easier maintenance and replacement of components like the filter housing, and incorporating a reverse motor structure to improve suction efficiency and battery performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the control module is integrated with the main body, then the cleaner has a compact structure, but the filter housing cannot be replaced without separating the control module
Solution Approach 1:
The control module is designed as a separate detachable component from the main body, allowing the filter housing to be accessed and replaced independently. This segmentation enables the filter housing to be removed without detaching the control module, resolving the contradiction between compact structure and ease of repair.
Solution Approach 2:
The control module is extracted as an independent detachable unit from the main body structure. This extraction allows the filter housing to be replaced separately while maintaining the compact overall structure, as the control module remains attached to the main body during filter replacement operations.
2Stability of the object's composition
If the control module is fixed to the main body, then the structure is stable, but the control module cannot be easily detached for maintenance
Solution Approach 1:
The control module is designed with dynamic attachment and detachment capabilities, allowing it to be firmly fixed during operation for structural stability, yet easily removed for maintenance. The detachable connection mechanism enables transition between fixed and separated states, resolving the contradiction between stability and ease of repair.
3Device complexity
If the control module is integrated into the main body, then the cleaner has fewer components, but airflow resistance increases
Solution Approach 1:
The control module is segmented as a separate detachable component rather than being fully integrated into the main body. This segmentation creates dedicated airflow passages that reduce turbulence and resistance, while maintaining a simplified overall structure with fewer total components, resolving the contradiction between device complexity and airflow resistance.
4Reliability
If the control module is permanently attached, then the cleaner is more reliable, but battery life is reduced due to continuous power consumption
Solution Approach 1:
The control module is designed with dynamic power management, where the detachable connection allows the system to enter low-power states when the control module is separated. This dynamic approach maintains operational reliability during use while extending battery life through reduced power consumption during storage or maintenance periods, resolving the contradiction between reliability and battery life.

AI summary
A cleaner is provided and includes a cleaner main body including a suction motor, a battery module and a control module configured to control an operation of the cleaner. The control module is mountable on and separable from the cleaner main body. The control module includes a main processor configured to communicate with the battery module at a preset interval in a state in which the control module is mounted on the cleaner main body. The battery module is configured to identify that the control module is separated from the cleaner main body and to stop a supply of power to the cleaner main body based on not receiving a communication signal from the control module for the preset first time period or longer.
