Ultrasonic Housing Filter Assembly for Heat-Dissipating Vent Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic apparatus assembly is costly due to the use of heat fusion and separate molds for filters, and disassembly is difficult, necessitating additional processes and equipment investment.
Innovation Solution
An ultrasonic apparatus with a grille integrated into the housing openings, a filter to prevent foreign substances, and a fastening member to secure the filter, along with a manufacturing method that includes forming a hook on the grille to guide the filter's position and forming discharge holes to prevent foreign substance entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heat fusion is used to assemble the filter, then the filter is securely fixed to the housing, but investment costs for jigs and equipment increase and disassembly becomes difficult
Solution Approach 1:
The filter assembly is segmented into modular components that can be independently assembled and disassembled. The filter element, frame, and sealing components are separated to allow easy replacement without requiring complete disassembly of the housing, thereby reducing manufacturing costs while maintaining secure fixation.
Solution Approach 2:
The filter assembly incorporates dynamic fastening mechanisms that allow for easy installation and removal. The design enables the filter to be securely fixed during operation while allowing quick disassembly for maintenance or replacement, eliminating the need for expensive heat fusion equipment and jigs.
2Shape
If a separate mold is used to assemble the filter, then the shape of the filter is maintained, but additional investment in mold is required and an additional assembly process is needed
Solution Approach 1:
The filter shape-forming function is merged with the housing structure itself. The housing includes integrated guide surfaces and positioning features that automatically maintain the filter's shape during assembly, eliminating the need for separate molds and reducing assembly process complexity.
Solution Approach 2:
The filter assembly design incorporates self-aligning and self-positioning features that allow the filter to maintain its shape without external mold support. The housing structure provides built-in guidance and constraint features that automatically ensure proper filter orientation and shape during installation.
3Object-affected harmful factors
If the filter is tightly sealed to prevent foreign substances, then foreign substance prevention is effective, but heat dissipation from the electrical component is reduced
Solution Approach 1:
The filter incorporates porous filtering materials that allow heat to pass through while blocking foreign substances. The porous structure provides sufficient thermal conductivity to maintain effective heat dissipation from the electrical component while achieving the required level of foreign substance prevention.
Solution Approach 2:
The filter assembly uses composite materials that combine filtering and heat transfer functions. The multi-layer construction includes heat-conductive layers for thermal management and filtering layers for particle removal, allowing simultaneous achievement of foreign substance prevention and effective heat dissipation.
