Vacuum Cleaner Fan Mounting Ring for Universal Noise Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vacuum cleaner designs require multiple types of bearing elements for mounting the vacuum cleaner fan with and without an insulating capsule, leading to increased production costs, storage complexity, and noise issues due to rigid couplings.
Innovation Solution
The use of identical bearing elements, comprising a bearing ring and buffers, which can mount the vacuum cleaner fan and insulating capsule independently, ensuring mechanical and acoustic decoupling, thus allowing the same parts to be used for both configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different bearing elements are used for mounting the vacuum cleaner fan with and without an insulating capsule, then the mounting can be optimized for each configuration, but the number of individual parts increases and production costs rise
Solution Approach 1:
The bearing element is designed with a universal structure that can accommodate both the vacuum cleaner fan directly and the insulating capsule surrounding the fan. The bearing element includes a mounting surface and a recess that can receive either the fan motor housing or the insulating capsule, allowing the same bearing element to serve both mounting configurations without modification.
2Reliability
If multiple variants of bearing elements are produced for different configurations, then each variant can be optimized, but storage costs and production complexity increase
Solution Approach 1:
The bearing element is designed as a universal component that eliminates the need for multiple variants. The structure includes adjustable mounting surfaces and recesses that can accommodate different configurations (with or without insulating capsule) using the same bearing element design, thereby reducing inventory variety to a single standardized component.
3Stability of the object's composition
If rigid mounting structures are used for the vacuum cleaner fan, then structural stability is improved, but noise development increases
Solution Approach 1:
The bearing element incorporates elastic cushioning elements in the form of buffers or damping material between the vacuum cleaner fan (or insulating capsule) and the housing. These cushioning elements are pre-installed in the bearing element structure to absorb vibrations and reduce noise generation before they can propagate to the housing, while still maintaining structural stability through the rigid portions of the bearing element.

Function Achieved in This Case
This solution reduces production costs, simplifies assembly, and minimizes noise by using the same bearing elements for both scenarios, while maintaining mechanical and acoustic decoupling, resulting in cost and material savings.
Implementation Method 1
holding the vacuum cleaner fan and the insulating capsule in a manner that the vacuum cleaner fan and the insulating capsule are also mechanically decoupled from one another
Implementation Method 2

AI summary
The cleaner has bearing elements mounting a vacuum cleaner fan (10) with and without a surrounding damming capsule. The vacuum cleaner fan comprises a fan unit with a suction hood (28) and a suction opening (34). A bearing ring (14) comprises a bearing ring opening passed to the suction opening and remains free at center of the cleaner. The bearing ring functions as a front-side bearing element. The bearing ring comprises recesses arranged over an outer periphery and set back from an outer peripheral surface.
