Cleaning Unit For Suction Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner suction heads with rotating brushes have complex assemblies and high manufacturing costs due to numerous parts, and the locking mechanism is not intuitive, leading to potential coupling defects and degradation of the brush.
Innovation Solution
A cleaning unit with a closure cap featuring elastically deformable locking members that automatically lock onto the main body upon insertion of the rotating brush, simplifying assembly and reducing costs by integrating the locking member and actuating member into a single piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure cap with multiple locking members and an actuating member is used to ensure reliable locking of the rotating brush, then the locking reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The locking member and actuating member are merged into a single integrated component. The locking member includes an actuating portion that can be manually operated to transition between locked and unlocked positions, eliminating the need for separate locking and actuating components. This reduces the number of parts while maintaining reliable locking functionality.
2Reliability
If a complex closure cap assembly with multiple parts is used to ensure secure locking, then the locking reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The locking member and actuating member are manufactured as a single integrated part, reducing the number of components that need to be produced, inventoried, and assembled. This simplification directly reduces manufacturing costs while maintaining the secure locking function through the integrated design.
3Reliability
If a manual actuating mechanism is used to lock the closure cap, then the locking reliability is improved, but the ease of operation decreases due to non-intuitive manipulation
Solution Approach 1:
The locking mechanism is designed to be self-evident and self-operating. The locking member's actuating portion is positioned and shaped to be naturally accessible and intuitive for user manipulation. The transition between locked and unlocked states provides tactile feedback, allowing users to understand and operate the mechanism without instructions, thereby improving ease of operation while maintaining reliability.
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 solution provides a simple, ergonomic, and cost-effective locking mechanism that ensures easy and reliable attachment of the rotating brush, minimizing manufacturing costs and reducing the risk of coupling defects.
Implementation Method 1
The locking member (18) is elastically deformable, and the closure cap (16) is configured such that the locking member (18) is elastically compressed when the locking member (18) is displaced towards the release position and such that the locking member (18) elastically relaxes towards the locking position when the locking member (18) occupies the release position

AI summary
A cleaning unit includes a rotating brush configured to be removably mounted in a receiving housing of a suction head, and a closure cap configured to close a passage opening provided on the suction head and through which the rotating brush is adapted to be removed from the receiving housing. The closure cap includes a cap body; a locking member which is elastically deformable and movable between locking and release positions; and an actuating member configured to displace the locking member from the locking position to the release position.
