Solution Overview
Problem
The industrial-scale manufacture of V-type filter assemblies faces challenges in applying adhesive sealants effectively between frame components and filter media packs, which complicates the assembly process and can lead to gas leakage.
Innovation Solution
A V-type filter frame design featuring a molded plastic front plate with grooves and troughs that allow for simultaneous application of fluid sealant, enabling the sealing of filter media packs and side plates in a single step, along with a snap-lock mechanism for easier handling and increased structural rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive sealant is used to strengthen the frame construction and prevent gas leakage, then the sealing reliability is improved, but the manufacturing complexity and time increase due to separate adhesive application steps
Solution Approach 1:
The groove and trough are integrated into a single unified structure that performs both functions: the groove provides mechanical connection between frame components while the trough receives and guides the adhesive sealant. This merging eliminates the need for separate adhesive application steps and tools, reducing manufacturing complexity while maintaining sealing reliability.
Solution Approach 2:
The groove and trough structures are pre-formed as integral parts of the frame components during manufacturing. This preliminary preparation of sealing pathways eliminates the need for separate adhesive application steps, reducing both manufacturing complexity and time while ensuring consistent sealing quality.
2Strength
If adhesive sealant is applied to join and seal frame components, then the structural strength is improved, but the manufacturing time increases due to multiple separate assembly steps
Solution Approach 1:
The groove and trough are combined into a single integrated feature that simultaneously provides mechanical joining and adhesive sealing pathways. This allows structural strength and sealing to be achieved in a single manufacturing step rather than multiple separate steps, thereby improving productivity while maintaining structural strength.
Solution Approach 2:
The groove and trough structures are pre-formed during frame component manufacturing, preparing the pathways for adhesive flow in advance. This preliminary action eliminates the need for separate adhesive application and curing steps, reducing manufacturing time while ensuring adequate structural strength through proper adhesive placement.
3Manufacturing precision
If separate adhesive application steps are used to seal frame components, then the sealing quality can be controlled, but the assembly complexity and manufacturing time increase
Solution Approach 1:
The groove and trough are integrated into a single structure that combines mechanical connection and adhesive sealing functions. This merging maintains sealing quality control through the designed groove geometry while eliminating separate adhesive application steps, thereby reducing manufacturing time without sacrificing sealing precision.
Solution Approach 2:
The groove and trough are pre-formed with precise dimensions and geometries during frame manufacturing, establishing controlled pathways for adhesive flow. This preliminary precision work ensures consistent sealing quality while eliminating the need for separate, time-consuming adhesive application and curing steps.
