Water Purifier Vibration Damping via Intermediary Filter Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers experience vibration transmission to the filter bracket and water purifier body due to pressure differences between the pump and the main water purifying filter, leading to noise and vibration issues.
Innovation Solution
Incorporation of a vibration transmission-preventing unit, including a filter vibration-damping member and an elastic band member, to reduce vibration transmission, along with pump vibration-damping members to attenuate noise and vibrations, using rubber materials for effective damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a pump is used to supply water to the reverse osmosis filter at predetermined filtration pressure, then water filtration function is improved, but vibrations due to pressure difference are transmitted to the filter bracket and water purifier body
Solution Approach 1:
A vibration-damping member made of elastic material (such as rubber) is introduced as an intermediary between the reverse osmosis filter and the filter bracket. This intermediary absorbs and dampens vibrations caused by pressure differences during water supply, preventing their transmission to the filter bracket and water purifier body while maintaining the pump's filtration pressure function
Solution Approach 2:
The vibration-damping member changes the mechanical parameters (vibration amplitude and frequency) of the system by introducing an elastic element that can deform and absorb vibrational energy. This transforms the rigid connection into a compliant one that filters out harmful vibrations while preserving the necessary pressure for filtration
2Object-generated harmful factors
If vibration-proof rubber members are used to attenuate pump noise and vibrations, then noise reduction is improved, but vibrations due to pressure difference are still transmitted through the reverse osmosis filter
Solution Approach 1:
The vibration-damping member serves as a dedicated intermediary specifically positioned at the reverse osmosis filter connection point to block the transmission path of pressure-difference-induced vibrations, complementing the pump's vibration-proof rubber members and providing comprehensive vibration isolation
Solution Approach 2:
The vibration control system is segmented into multiple independent components: vibration-proof rubber members at the pump level and a separate vibration-damping member at the reverse osmosis filter level. This segmentation allows each component to address specific vibration sources without interfering with the other, achieving both noise attenuation and vibration reduction

AI summary
A water purifier includes a water purifier body, a filter bracket provided inside the water purifier body, a pump unit provided inside the water purifier body and including a pump connected to a main water purifying filter installed in the filter bracket, and a vibration transmission-preventing unit which, while the main water purifying filter is installed in the filter bracket, ensures the transmission, to the filter bracket and the water purifier body, of vibrations due to the pressure difference between the pump and the main water purifying filter when water is supplied to the main water purifying filter by means of the pump is reduced by a filter vibration-damping member.
