Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing filtering apparatuses suffer from relative vibration of the filtering membrane module during aeration cleaning, leading to damage and potential separation from the frame structure, which shortens the replacement cycle and increases costs.
Innovation Solution
A filtering apparatus design featuring a frame structure with a cross bar and filtering membrane module where the header has a receiver with a through-hole for a rib, and a stopper is used to prevent separation by fastening the rib with a bolt and nut, minimizing vibration through the use of additional ribs and protrusions for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filtering membrane module is coupled loosely to the frame structure, then the ease of installation is improved, but the relative vibration during aeration cleaning increases causing damage and separation
Solution Approach 1:
The coupling mechanism transitions from a static rigid connection to a dynamic system that accommodates operational movements. The elastic coupling member allows for controlled flexibility during installation while maintaining stability during aeration cleaning through the combined action of the rib-receiver-stopper mechanism and elastic coupling.
Solution Approach 2:
The coupling system combines multiple materials with different properties: the rigid rib and stopper provide structural support and positioning, the elastic coupling member provides flexibility and shock absorption, and the receiver provides precise positioning. This composite approach resolves the contradiction between ease of installation and operational stability.
2Productivity
If strong aeration is applied for effective cleaning, then the cleaning efficiency is improved, but the relative vibration of the filtering membrane module increases
Solution Approach 1:
The stopper and rib mechanism is installed beforehand to prevent excessive vibration during aeration cleaning. The stopper limits the range of motion of the filtering membrane module, cushioning against the harmful effects of strong aeration before damage can occur.
Solution Approach 2:
The elastic coupling member acts as an intermediary between the frame structure and the filtering membrane module. It transmits necessary forces for stable positioning while absorbing and dampening the vibrational forces generated during strong aeration cleaning, thus protecting the module from vibration-induced damage.
3Reliability
If the filtering membrane module is securely fastened, then the prevention of separation is improved, but the device complexity increases
Solution Approach 1:
The coupling mechanism is segmented into distinct functional components: the rib for positioning, the receiver for接纳 and alignment, the stopper for limiting motion and preventing separation, and the elastic coupling member for flexibility. This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated fastening system.
Solution Approach 2:
Instead of using a complex fastening system to secure the module, the design inverts the approach by using a simple stopper that prevents separation through geometric constraint rather than mechanical fastening. The stopper blocks the module from moving outward, providing secure attachment with minimal complexity.
