Solution Overview
Problem
Existing handheld vacuum cleaners often require complex disassembly for filter replacement and battery charging, which can be inconvenient and time-consuming.
Innovation Solution
A handheld vacuum cleaner design featuring a detachable filter assembly that slides along the handle for easy removal and replacement, and a battery pack housed within the handle that can be exchanged or charged without disassembling the appliance, with integrated switches for motor control and acoustic foam for noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the filter assembly is integrated into the body of the vacuum cleaner, then the structural integrity is improved, but the ease of filter replacement deteriorates
Solution Approach 1:
The filter assembly is segmented from the main body as a separate, detachable component. This allows the filter assembly to be removed and replaced independently without disassembling the entire vacuum cleaner, resolving the contradiction by enabling easy maintenance while maintaining structural integrity when assembled.
Solution Approach 2:
The filter assembly is designed to nest within the handle structure when detached from the body. The bore of the filter assembly allows it to slide along the handle and be stored within the handle's internal cavity, providing compact storage while maintaining easy accessibility for replacement.
2Volume of moving object
If the vacuum cleaner has a compact design with co-axial handle and body, then the portability is improved, but the ease of disassembly for maintenance deteriorates
Solution Approach 1:
The filter assembly is segmented as a separate component that can be independently removed from the compact body. This segmentation allows maintenance access without requiring disassembly of the compact structure, resolving the contradiction between compactness and ease of maintenance.
Solution Approach 2:
The filter assembly is extracted as a removable component from the compact vacuum cleaner body. This extraction enables users to access and replace the filter without compromising the compact design, as the filter assembly can be taken out independently through a simple detachment mechanism.
3Stability of the object's composition
If the battery pack is permanently integrated into the handle, then the structural stability is improved, but the ease of battery replacement deteriorates
Solution Approach 1:
The battery pack is segmented from the handle as a separate, removable component. This segmentation maintains structural stability when assembled while enabling easy battery replacement by allowing users to detach and swap battery packs without disassembling the handle or other permanent structures.

AI summary
A vacuum cleaning appliance includes a body having a longitudinal axis, and a motor unit located in the body for creating an airflow through the appliance. A handle extending along the longitudinal axis has a first end connected to the body and a free, second end. A filter assembly is detachably connected to the body proximate to the first end of the handle. The filter assembly defines a bore running through the filter assembly along the longitudinal axis, the bore being shaped to allow the filter assembly to slide along the handle towards the second end thereof following detachment from the body.
