Removable Hand Vacuum With Supplemental Bin for Higher Dirt Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stick vacuum cleaners have limited dirt collection capacity, making them less effective for cleaning large areas and requiring frequent emptying, while upright vacuum cleaners have bulky dirt collection pods that are inefficient for above-floor cleaning.
Innovation Solution
A multimode surface cleaning apparatus with a removable hand vacuum cleaner and a supplemental dirt collection bin that can be mounted to the upright section, providing enhanced dirt collection capacity and allowing for different operational modes, including a large dirt capacity upright mode and a lightweight upright mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand vacuum cleaner is used for above-floor cleaning, then portability and ease of operation are improved, but dirt collection capacity is limited
Solution Approach 1:
The patent combines a hand vacuum cleaner with a supplemental dirt collection bin, merging the portability advantages of hand vacuums with the extended capacity of larger collection systems. The hand vacuum cleaner remains removable and can be detached when not needed, while the supplemental bin provides additional storage when attached.
Solution Approach 2:
The system dynamically adapts between two configurations: operating as a lightweight hand vacuum for portability-critical tasks, and operating as an extended-capacity vacuum when the supplemental bin is attached. The hand vacuum cleaner can be removed or attached based on the specific cleaning task requirements.
2Quantity of substance
If an upright vacuum cleaner with a large dirt collection pod is used, then dirt collection capacity is improved, but the device becomes bulky and inefficient for above-floor cleaning
Solution Approach 1:
The dirt collection system is segmented into two separate components: the main dirt collection pod of the upright vacuum and a removable supplemental dirt collection bin. This segmentation allows the supplemental bin to be detached when portability is needed, while providing additional capacity when attached for large-area cleaning tasks.
Solution Approach 2:
The supplemental dirt collection bin serves multiple functions: it extends capacity for large-area floor cleaning, can be removed to reduce bulk for above-floor cleaning, and provides flexible adaptation to different cleaning scenarios. The same component enables both high-capacity and portable modes.
3Productivity
If frequent emptying is required to maintain cleaning effectiveness, then dirt collection capacity is effectively reduced, but cleaning intervals are shortened
Solution Approach 1:
The supplemental dirt collection bin is attached in advance for large-area cleaning tasks, providing pre-configured extended capacity. This preliminary preparation eliminates the need for frequent trips to empty the main pod, allowing continuous operation over extended periods without interruption.
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
The apparatus offers extended cleaning intervals with reduced bulkiness, allowing for efficient cleaning of large areas and easy transition between floor and above-floor cleaning tasks without the need for frequent emptying.
Implementation Method 1
a cyclone chamber, a dirt collection region, a suction motor and a clean air outlet
Implementation Method 2
dirt separated in the cyclone chamber is collectable in the dirt collection chamber
