Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface cleaning apparatuses face challenges in maneuverability and ease of use due to the weight of the portable cleaning unit, which affects their ability to navigate around obstacles and change operating modes without disrupting airflow communication.
Innovation Solution
A reconfigurable surface cleaning apparatus with a detachable portable surface cleaning unit connected via a flexible conduit, allowing for multiple operating modes, including upright, portable, and auxiliary configurations, without the need to reconfigure airflow conduits, and enabling one-handed operation of the portable unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable cleaning unit is mounted on the support structure, then the cleaning apparatus can operate in upright mode with stable airflow, but the weight increases and maneuverability around obstacles deteriorates
Solution Approach 1:
The cleaning apparatus is divided into separable components: the portable cleaning unit can be detached from the support structure. The airflow conduit is also segmented into a flexible portion that can be disconnected, allowing the cleaning unit to be removed while maintaining the option to preserve airflow connection for continuous operation capability.
Solution Approach 2:
The mounting configuration is made dynamic and reconfigurable. The portable cleaning unit can be attached or detached from the support structure as needed, and the flexible conduit can be reconfigured or disconnected. This allows the system to adapt between upright stable operation and portable maneuverable operation based on cleaning requirements.
2Ease of operation
If the portable cleaning unit is detached from the support structure, then maneuverability improves and weight burden is reduced, but maintaining airflow communication becomes difficult
Solution Approach 1:
A flexible conduit is used to connect the portable cleaning unit to the support structure's airflow system. This flexible hose allows the cleaning unit to be detached and repositioned while maintaining airflow communication, enabling the user to carry the unit separately while keeping the airflow path intact for continuous cleaning operation.
Solution Approach 2:
The flexible conduit acts as an intermediary element between the portable cleaning unit and the support structure. It mediates the connection, allowing the unit to be detached from rigid mounting while preserving airflow communication through the flexible hose, thus enabling both maneuverability and continuous operation.
3Stability of the object's composition
If conventional rigid airflow conduits are used, then structural stability is maintained, but reconfiguring for different operating modes requires time-consuming disconnection and reconnection
Solution Approach 1:
The rigid airflow conduit is replaced with a flexible hose that can be easily reconfigured. This flexible conduit allows quick connection and disconnection between operating modes without requiring complex reassembly, significantly reducing the time needed to switch between upright and portable configurations while maintaining adequate structural stability for airflow transmission.
Solution Approach 2:
The airflow conduit system is made dynamic and reconfigurable. The flexible hose can be easily connected or disconnected to adapt to different operating modes, allowing rapid transition between upright stable operation and portable maneuverable operation without time-consuming reassembly of rigid components.
4Ease of operation
If the portable cleaning unit is designed for one-handed operation, then ease of use improves, but the mounting and dismounting mechanism complexity increases
Solution Approach 1:
The complex mounting and dismounting mechanism is extracted and integrated into the portable cleaning unit itself, allowing one-handed operation. The unit is designed with built-in attachment and detachment features that can be operated with one hand, simplifying the user interaction while the mechanical complexity is contained within the unit's structure rather than requiring additional external mechanisms.

AI summary
A surface cleaning apparatus comprises a floor cleaning unit comprising a surface cleaning head and an upright section moveably mounted to the surface cleaning head between a storage position and a floor cleaning position and a hand vacuum cleaner removably mounted to the upright section. The upright section is connected to the surface cleaning head by a rotatable coupling. When the surface cleaning unit is mounted to the upright section, the surface cleaning unit and the upright section define an upright assembly, the upright assembly having a handle wherein, when the upright assembly is in the inclined use position, the handle is steeringly connected to the surface cleaning head whereby a user may rotate the handle clockwise or counterclockwise with respect to the surface cleaning head to assist in steering the surface cleaning head.
