Handheld cyclonic vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable cyclonic vacuum cleaners with transparent cyclonic enclosures are prone to scratching and stress on joints or seals when placed on supports, affecting their lifespan and integrity.
Innovation Solution
The cyclonic enclosure's base is offset from the support plane, eliminating friction and stress, with support means like longitudinal and transverse ribs providing stability and a low center of gravity, and an elastomeric material for shock absorption, ensuring the enclosure does not touch the support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cyclonic enclosure base is made transparent for visual inspection, then the aesthetic appearance and ease of monitoring are improved, but the base becomes susceptible to scratching and damage when placed on supports
Solution Approach 1:
The patent introduces an intermediary element (the offset base design with support feet) that separates the transparent cyclonic enclosure base from direct contact with external supports. This mediator prevents harmful interactions while preserving the transparency benefit for visual inspection of the cyclone chamber.
2Stability of the object's composition
If the vacuum cleaner is designed to rest directly on its base for stability, then the stability is improved, but the base and seals are stressed and scratched when placed on supports
Solution Approach 1:
The base is segmented into multiple functional elements: the main transparent base for the cyclonic enclosure, separate support feet that contact the ground, and an offset arrangement that distributes weight. This segmentation allows the transparent base to maintain structural integrity while the separate support feet provide stable ground contact.
3Reliability
If the base of the cyclonic enclosure is offset from the support plane, then the base is protected from scratching and stress, but additional support means are required to maintain stability
Solution Approach 1:
The support feet are designed with elastomeric material that provides flexible, compliant contact with support surfaces. This flexible material absorbs minor irregularities and prevents stress concentration, maintaining base protection while simplifying the overall support structure through material properties rather than complex mechanical designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the cyclonic enclosure's resistance to scratches and stress, improves stability, and extends the lifespan by preventing contact with supports, ensuring the vacuum cleaner remains stable and functional.
Implementation Method 1
a cyclonic enclosure secured to the main body, and arranged to separate impurities from an air flow traversing the air circuit
Implementation Method 2
when devoid of accessories, the sole weight of the main body, which comprises electrical energy storage means, is sufficient to ensure the stability of the portable cyclonic vacuum cleaner on its support means
Implementation Method 3
an elastomeric material for shock absorption
