Cleaner Head Front-Pivot Cover for Orthogonal Agitator Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaner heads for vacuum cleaners are cumbersome and inefficient in accessing and replacing the agitator, which is crucial for maintenance and cleaning, and lack a design that allows for easy and secure attachment of components.
Innovation Solution
A cleaner head design featuring a pivotable cover on the front side of the housing that allows orthogonal access to the agitator chamber, along with a snap-fit mechanism and a flexible outlet pipe for easy agitator removal and replacement, and a modular construction for improved maintenance and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is fixed to the housing, then the structure is simple and stable, but the agitator cannot be accessed or removed for maintenance
Solution Approach 1:
The cover is designed to be movable rather than fixed, allowing it to pivot between a closed position (providing structural stability) and an open position (providing access to the agitator). This dynamic design resolves the contradiction by enabling both structural integrity and maintenance access through a single movable component.
Solution Approach 2:
The cover mechanism is divided into separable components including the cover itself, hinges, and latches, allowing independent movement and assembly. This segmentation enables the cover to be opened for agitator access while maintaining a simple overall structure when closed.
2Ease of operation
If the opening for agitator access is large, then the agitator can be easily removed, but suction is compromised during operation
Solution Approach 1:
The cover dynamically transitions between closed and open states. When closed during operation, it maintains suction performance by sealing the opening. When opened for maintenance, it provides full access to the agitator. This dynamic behavior resolves the contradiction between maintaining suction and enabling agitator removal.
Solution Approach 2:
The cover is designed to be opened completely before agitator removal begins, ensuring that the entire agitator can be accessed without compromising suction during the actual cleaning operation. The preliminary opening action separates the maintenance phase from the operation phase.
3Ease of repair
If the cover is permanently attached to the housing, then the structure is stable, but maintenance access is difficult
Solution Approach 1:
The cover connection transitions from a static permanently-attached state to a dynamic reversible state through hinges and latches. This allows the cover to be securely attached during operation (maintaining structural stability) yet easily detached or opened for maintenance (enabling agitator replacement).
Solution Approach 2:
The connection mechanism is segmented into movable hinge joints and detachable latch components, separating the functions of structural attachment and maintenance access. This segmentation allows the cover to be securely connected when needed while remaining easily separable for repairs.
4Adaptability or versatility
If the outlet pipe is rigid, then the structure is stable, but flexibility and adaptability are reduced
Solution Approach 1:
The outlet pipe incorporates flexible sections that allow the pipe to bend and adapt to different positions while maintaining a stable connection. The flexible material provides both the needed adaptability for various configurations and sufficient structural integrity for stable operation.
Solution Approach 2:
The outlet pipe transitions from a completely rigid structure to a dynamically flexible structure that can adapt its shape while maintaining connection stability. This dynamic flexibility allows the pipe to accommodate different positions and orientations without compromising the overall system stability.

AI summary
A cleaner head for a cleaning appliance, including: an agitator rotatable about an axis; a housing having a front side, a rear side and first and second sides which extend between the front side and rear side, said housing at least partially defining a chamber, wherein said chamber at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet, wherein the housing is movable along a surface to be cleaned; wherein the chamber includes an opening for permitting access to and removal of the agitator from the chamber; a cover cooperatively associated with the housing for permitting access to the chamber through the opening; wherein the cover is movable to an agitator access position to permit the agitator to be removed from the chamber through the opening in a direction substantially orthogonal to the axis of the agitator and in a direction which is substantially parallel to a plane of the surface to be cleaned.
