Swappable Floor Cleaning Heads With Sensor-Guided Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface treatment appliances lack versatility and efficiency in cleaning different floor types, as they often require multiple devices for various cleaning modes and struggle with balanced distribution of components like water reservoirs and heating elements, leading to uneven cleaning performance.
Innovation Solution
A multi-functional surface treating device with swappable heads, including a steam cleaning head with a water reservoir and heating element on the same plane, and a brush roll with adjustable modes, along with an adjustable spray outlet and sensor-controlled fluid management, allowing for adaptable cleaning of hard floors, carpets, and steam cleaning with balanced component distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate devices are used for different cleaning modes (steam cleaning, hard floor cleaning, carpet cleaning), then cleaning versatility is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent implements a universal cleaning device with a single body that can accommodate multiple types of cleaning heads (steam cleaning head, hard floor cleaning head, carpet cleaning head) through a standardized connector system. This allows one device to perform multiple cleaning functions that would otherwise require separate devices, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The cleaning device is divided into modular components: a main body containing control systems and fluid reservoirs, and interchangeable cleaning heads that can be attached or removed as needed. This segmentation allows the user to select only the required cleaning head for each task, providing versatility without requiring all cleaning functions to be permanently integrated into one complex unit.
2Ease of manufacture
If water reservoir and heating element are positioned at different locations in the steam cleaning head, then component layout flexibility is improved, but balance and stability during operation deteriorate
Solution Approach 1:
The patent positions the water reservoir and heating element at specific asymmetric locations within the steam cleaning head, with the water reservoir located at one end and the heating element positioned to create balanced weight distribution. This asymmetric yet balanced layout allows for ease of manufacturing while maintaining operational stability and preventing uneven force distribution during use.

AI summary
A floor treatment device may include a body portion comprising one or more pumps, one or more spray outlets, and one or more reservoir receptacles configured to receive one or more reservoirs. The one or more pumps are operable to be activated and direct liquids to the spray outlets. The device may include swappable heads, each comprising a body connector configured to mate with a head connector of the body portion. In an embodiment, the head connector may include a sensor system and a controller communicatively connected to the sensor system. When one of swappable heads is connected to the body portion, the sensor system is configured to detect the identity of the swappable heads connected, and the controller is configured to selectively activate, based on the identity of the swappable heads, at least one of the one or more pumps.
