Surface cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses face challenges in efficiently managing the removable components, such as the above-floor cleaning wand and portable surface cleaning unit, which can complicate user operation and maintenance due to complex reconfiguration requirements and alignment issues during installation and use.
Innovation Solution
A surface cleaning apparatus design featuring a wand release actuator and wand lock mechanism that allows for easy removal and reinstallation of the above-floor cleaning wand, along with a portable surface cleaning unit that can be securely locked and unlocked, facilitating simpler operation and maintenance by reducing the vertical extent of the upper portion and providing improved alignment and handling during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the above-floor cleaning wand is permanently fixed to the upper portion, then the structural stability is improved, but the ease of operation deteriorates due to inability to remove for maintenance and storage
Solution Approach 1:
The cleaning apparatus is divided into separable components: the upper portion, the above-floor cleaning wand, and the portable surface cleaning unit. The wand can be selectively removed from the upper portion using a wand release actuator, allowing the system to transition between a stable fixed configuration and an operable separated configuration. This segmentation enables both structural stability when assembled and ease of operation when components need to be removed for maintenance, storage, or alternative cleaning tasks.
2Reliability
If the upper portion has large vertical extent to accommodate locking mechanisms, then the reliability of component attachment is improved, but the ease of operation deteriorates due to difficulty in aligning and installing components
Solution Approach 1:
The wand and portable surface cleaning unit are pre-configured with alignment features and release actuators that guide proper installation. The wand release actuator is positioned to be easily accessible, and the locking mechanisms are pre-positioned within the upper portion to automatically engage when components are inserted. This preliminary configuration of alignment and release features reduces the vertical extent needed while maintaining reliable attachment and ease of operation.
3Device complexity
If the wand lock mechanism is integrated into the upper portion, then the device complexity is reduced, but the ease of repair deteriorates because the lock mechanism cannot be independently maintained
Solution Approach 1:
The wand lock mechanism is designed as a separable component that can be independently removed with the wand from the upper portion. This segmentation allows the locking mechanism to be maintained, repaired, or replaced without disassembling the entire upper portion assembly. The wand release actuator and locking members are configured to be self-contained units that can be serviced independently, improving ease of repair while maintaining acceptable device complexity.

AI summary
A surface cleaning apparatus has a surface cleaning head and an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion has upper portion laterally extending members. An above floor cleaning wand is removably receivable in air flow communication with the upper portion. The wand has wand laterally extending members, wherein, when the wand is received in air flow communication with the upper portion and the upper portion is in the storage position, the wand has a lower end and an upper end spaced from the lower end along a wand axis and the wand laterally extending members are positioned above the upper portion laterally extending members. A portable surface cleaning unit is removably mounted to the upper portion wherein, when the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the upper portion has lower mounting members which engage the upper portion laterally extending members and upper mounting members which engage the wand laterally extending members.
