Head for a surface cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surface cleaning devices lack the ability to easily interchange between hard floor and soft floor cleaning modes, leading to inefficiencies and potential damage to surfaces.
Innovation Solution
A head for a surface cleaning device featuring a movable inlet extension member and wheels for supporting the inlet extension member, allowing for adjustable positioning between cleaning modes to accommodate different floor types, with resilient biasing means and an actuator for manual or electronic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning device is configured for a fixed cleaning mode (either hard floor or soft floor), then the cleaning effectiveness for that specific mode is optimized, but the device cannot readily interchange between different floor types
Solution Approach 1:
The inlet extension member is made movable between retracted and extended positions, allowing the cleaning head to dynamically adapt its configuration. This dynamic structure enables the same device to handle both hard floors (retracted position) and soft floors (extended position) without requiring multiple fixed configurations, thus resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If the inlet extension member is extended for soft floor cleaning, then the cleaning effectiveness on soft floors is improved, but the structure becomes more complex
Solution Approach 1:
The inlet structure is segmented into a fixed inlet and a movable inlet extension member. This segmentation allows the extension member to be independently controlled and positioned only when needed for soft floor cleaning, adding functionality without permanently increasing structural complexity. The segmented design enables selective deployment of the extension feature.
3Adaptability or versatility
If the inlet extension member is made movable to enable mode interchange, then the adaptability between floor types is improved, but the ease of operation is reduced
Solution Approach 1:
The inlet extension member is designed to be automatically positioned based on the cleaning surface type detected or selected. The system self-adjusts the extension member position without requiring complex manual intervention, thus maintaining ease of operation while achieving adaptability between different floor cleaning modes.

AI summary
A surface cleaning device including a head including an inlet in fluid communication with a fluid tank and a suction source. The inlet is configured to receive a cleaning fluid from a surface. The head further includes an inlet extension member that at least partially surrounds the inlet, the inlet extension member including an opening and the inlet extension member movable with respect to the inlet between a first position and a second position. In the first position, the inlet is closer to the surface than the opening of the inlet extension member and in the second position, the opening of the inlet extension member is closer to the surface than the inlet.
