Solution Overview
Problem
Existing air filters face challenges in achieving sufficient stability and ease of manufacture while maintaining effective air filtration performance, particularly in pulse filters where pulse air flow can cause uneven distribution of static pressure and potential damage to the filter media.
Innovation Solution
A filter media support structure featuring a latticework cage assembly with column and beam elements, made of corrosion-resistant plastic or polymer composite, that provides structural integrity and guides air flow to enhance pulse effect and stability, using injection molding for easy manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a cage made of rolled steel netting is used, then sufficient stability is provided, but manufacturing complexity and cost increase
Solution Approach 1:
The cage is divided into multiple cage wall members that can be manufactured separately and then assembled together. Each wall member is a discrete component that can be produced using simple injection molding processes, then connected through retaining rings to form the complete cage structure, simplifying manufacturing while maintaining stability.
Solution Approach 2:
The traditional rolled steel netting mechanical structure is replaced with plastic cage wall members manufactured by injection molding. This substitution eliminates complex metal forming processes and allows for simpler, more cost-effective production while achieving the required structural stability through the plastic material properties and lattice design.
2Strength
If a lattice work structure with column and beam elements is used, then strength is improved, but device complexity increases
Solution Approach 1:
The cage wall members are designed as multi-functional components that simultaneously provide structural support, maintain cage shape, and facilitate assembly. The lattice work pattern integrated into each wall member serves both strength requirements and manufacturing simplicity, as the same molded component provides multiple functions without requiring separate structural and aesthetic elements.
Solution Approach 2:
The column elements and beam elements are merged into a single integrated lattice work structure that is molded as one piece. This consolidation eliminates the need for separate components and joining processes, reducing assembly complexity while maintaining the strength benefits of a multi-element lattice design.
3Ease of operation
If column connecting sheet elements with curved portions are used, then air flow directionality is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The angle and curvature parameters of the sheet elements are optimized within specific ranges that balance air flow directionality with manufacturing feasibility. By defining acceptable parameter ranges rather than requiring precise single values, the design achieves effective air flow control while allowing for normal manufacturing variations without requiring excessive precision.
