Rotating Mop Cleaner Air-Hole Control for Automatic Water Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners require frequent manual operation to adjust water injection, leading to user inconvenience and inefficiency in water usage during the cleaning process.
Innovation Solution
A cleaner with a water cleaning device that includes a nozzle assembly, a rotatable cleaner body, and an adjusting device that opens or closes an air hole based on the cleaner's rotation, allowing for controlled water discharge during cleaning and preventing discharge in standby mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a manual knob operation is used to control water injection, then the water injection amount can be adjusted, but the user must frequently operate the knob during cleaning which leads to inconvenience
Solution Approach 1:
The adjusting device automatically opens or closes the air hole based on the rotation of the cleaner body, eliminating the need for manual knob operation. The system serves itself by using the cleaner's own motion to control water discharge, thereby resolving the contradiction between adjustability and ease of operation.
Solution Approach 2:
The manual mechanical knob operation is replaced with an automatic mechanical linkage system. The adjusting device is mechanically connected to the cleaner body rotation, automatically translating rotational motion into air hole opening/closing actions, thus replacing the need for separate manual control operations.
2Productivity
If the air hole remains open for continuous water discharge, then cleaning efficiency improves, but water is wasted when the cleaner is in standby mode
Solution Approach 1:
The air hole state transitions from static to dynamic, automatically opening when the cleaner body rotates (cleaning mode) and closing when stationary (standby mode). This dynamic adaptation allows the system to optimize water discharge based on operational state, improving cleaning efficiency while preventing water waste during standby.
Solution Approach 2:
The adjusting device provides automatic feedback control by sensing the cleaner body's rotation state and相应地 opening or closing the air hole. When rotation is detected, the air hole opens for water discharge; when rotation stops, the air hole closes to prevent waste, creating a self-regulating system that balances productivity and resource conservation.
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
Enhances user convenience by allowing continuous water discharge during cleaning without manual intervention and conserving water by preventing unintended discharge in standby mode.
Implementation Method 1
an elastic member that is configured to maintain the adjusting device in the first position to close the air hole
Implementation Method 2
a water tank that is configured to (i) hold a cloth and (ii) store water to provide to the cloth and that includes an air hole through which air enters the water tank from outside of the water tank
