Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses, such as vacuum cleaners, face challenges in efficiently discharging debris from the dirt collection chamber, leading to clogged air treatment members and reduced cleaning efficiency due to compacted debris.
Innovation Solution
A hand vacuum cleaner design featuring an openable cyclone chamber with a hinge extending along its axial length, allowing for easy access and discharge of debris, along with an openable energy storage chamber for battery access, and a cyclone bin assembly with a pivotally mounted rear end for improved dirt outlet operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cyclone chamber is made sealed for structural integrity, then structural strength is improved, but debris discharge becomes difficult and clogging increases
Solution Approach 1:
The cyclone chamber is divided into separate sections with independent access points. The dust collection chamber has a separate discharge opening from the cyclone separation chamber, allowing debris to be removed without opening the main cyclone chamber, thus maintaining structural integrity while enabling easy debris discharge.
Solution Approach 2:
The air treatment member is designed with self-cleaning functionality that operates before debris discharge. The rotating air treatment member prevents compacting of debris and maintains clear passages, preparing the system for efficient debris removal without requiring frequent chamber openings.
2Stability of the object's composition
If the air treatment member is fixed in position, then structural stability is improved, but cleaning efficiency decreases due to compacted debris
Solution Approach 1:
The air treatment member is designed to rotate about its central axis while maintaining its fixed position in the cyclone chamber. This rotational movement prevents debris from compacting against the fixed structure, maintaining clear air passages and sustained cleaning efficiency without compromising structural stability.
Solution Approach 2:
The rotating air treatment member creates dynamic movement that prevents debris compaction. The rotation generates forces that keep debris loose and prevent it from settling in a compacted state, thereby maintaining high cleaning efficiency throughout operation.
3Quantity of substance
If the dirt collection chamber is designed with large capacity, then debris storage is improved, but access for emptying becomes difficult
Solution Approach 1:
The dust collection system is segmented into the cyclone separation chamber and the dust collection chamber with separate access points. The dust collection chamber has its own discharge opening that can be accessed independently, allowing users to empty debris without disrupting the cyclone chamber or losing captured debris.
Solution Approach 2:
A dust outlet passage serves as an intermediary channel connecting the cyclone chamber to the dust collection chamber. This passage allows debris to be transported and discharged separately, providing easy access for emptying while maintaining the large capacity of both chambers.
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
Enhances debris discharge efficiency, reduces clogging, and provides easy access to energy storage, improving the overall cleaning performance and user experience.
Implementation Method 1
Air may be drawn into the surface cleaning apparatus through a dirty air inlet and conveyed to an air treatment member, such as, for example, a cyclonic air treatment member. Within the air treatment member, some of the particulate matter (i.e., debris) captured within the air flow may be disentrained from the air flow.
Implementation Method 2
a cyclone, such as a cyclone for a hand vac, has an openable door wherein the hinge extends generally in the direction of the cyclone axis of rotation
