Filter, manufacturing method for filter and air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioner filters face issues with complex manufacturing processes, low production efficiency, and poor filtering effects due to their carbon steel construction, which leads to rust, leakage risks, and limited effective filtering areas.
Innovation Solution
An integrally formed filter casing made from materials like stainless steel or copper, with a simplified manufacturing process that eliminates the need for splicing and coating, featuring a transition tube connection method that prevents leakage and enhances filtering efficiency through a U-shaped support strip design for the filter screen assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If carbon steel is used for the filter casing, then the material cost is low, but the casing requires coating to prevent rust and the manufacturing process becomes complex
Solution Approach 1:
The patent changes the material parameter from carbon steel to stainless steel or copper, which inherently possesses corrosion resistance. This eliminates the need for additional coating processes while maintaining structural integrity, thereby simplifying the manufacturing process and reducing complexity.
Solution Approach 2:
The patent integrates the casing structure into a single integral piece rather than assembling multiple components. This merging of parts eliminates the need for separate coating operations on multiple surfaces and simplifies the overall manufacturing process while maintaining structural strength.
2Reliability
If the casing is welded to the transition tube at low temperature, then the coating on the casing is protected, but the welding strength is insufficient and leakage risks increase
Solution Approach 1:
The patent removes the coating from the transition tube surface in the welding area, eliminating the harmful factor of coating burnout during high-temperature welding. This allows the welding process to proceed at optimal temperatures without compromising the coating, thereby ensuring both welding strength and preventing harmful effects.
Solution Approach 2:
The patent applies preliminary action by removing the coating from the welding area before the welding process. This preliminary removal prevents coating burnout during welding and ensures proper welding strength, thereby eliminating the need to compromise between coating protection and welding quality.
3Area of stationary object
If a short casing is used, then the filter size is compact, but the filter screen area is reduced and filtering effect becomes poor
Solution Approach 1:
The patent extends the filter screen area by utilizing the length dimension of the casing. By increasing the casing length, the filter screen can be made larger, thereby improving the filtering effect while maintaining a compact overall filter design through optimized dimensional proportions.
4Strength
If an integrally formed cross support is used in the filter screen, then the structural strength is enhanced, but raw material is wasted and the effective filtering area is reduced
Solution Approach 1:
The patent segments the support structure from the filter screen, using separate components instead of an integrally formed cross. This segmentation allows the support to be positioned only where structurally necessary, maximizing the effective filtering area while maintaining adequate structural strength through strategic support placement.
