Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter devices are cumbersome to change, require filters from specific manufacturers, and lack compatibility with HEPA filters, especially in high humidity and high volume flow applications.
Innovation Solution
A filter holding device comprising cup-shaped shell elements with interlocking extensions and a ring-shaped clamping element, allowing for easy filter exchange and compatibility with various filter types, including HEPA filters, with an airtight connection and demoldable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional filter holding devices are used with specific configurations for each filter type, then the filter is securely held in place, but the device complexity increases and filter exchange becomes cumbersome
Solution Approach 1:
The filter holding device uses a universal cup-shaped shell element design that can accommodate different filter types (standard filters and HEPA filters) through a single standardized interface. The shell element includes a standardized opening with tube connection that works with various filter configurations, eliminating the need for multiple specialized holder designs.
Solution Approach 2:
The filter holding device is divided into separable components: a reusable cup-shaped shell element and replaceable filter units. This segmentation allows the shell to remain standardized while only the filter portion needs to be changed, simplifying the overall system and reducing complexity.
2Manufacturing precision
If conventional filter holding devices are designed for specific filter types, then the filter fits precisely, but the ease of operation deteriorates due to cumbersome filter exchange
Solution Approach 1:
A universal coupling interface is provided in the cup-shaped shell element that accommodates different filter types including HEPA filters. The standardized opening and tube connection allow various filter units to be attached and detached easily while maintaining precise sealing and fit through the standardized interface design.
3Reliability
If conventional filter holders are designed with special design features, then the filter is securely retained, but adaptability deteriorates as filters are only available from specific manufacturers
Solution Approach 1:
The cup-shaped shell element provides a universal mounting structure with a standardized opening that can accommodate filters from different manufacturers. The standardized interface ensures secure retention through consistent sealing and mechanical coupling, while allowing compatibility with various filter types and manufacturers.
Solution Approach 2:
The cup-shaped shell element acts as an intermediary between the filter unit and the housing system. It provides a standardized interface layer that decouples the filter manufacturer from the housing manufacturer, allowing any filter with the compatible interface to be used securely in the housing.
4Ease of manufacture
If conventional filter devices are used in high humidity applications, then the filtering function is provided, but reliability deteriorates as HEPA filters are not commercially available
Solution Approach 1:
The filter holding device is designed with a universal interface that accommodates both standard filters and HEPA filters in high humidity applications. The cup-shaped shell element and standardized opening allow HEPA filters to be installed in dehumidifier devices, expanding filter options for high humidity environments where HEPA filtration is required.
