Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive agents are used to attach the filter to the holding member, then the filter attachment becomes more fixed and secure, but the production process becomes complicated and manufacturing costs increase
Solution Approach 1:
The invention extracts and eliminates the adhesive agent from the filter attachment system. Instead of using adhesive to secure the filter, the design employs a mechanical retention mechanism where the filter is held in place by the structural configuration of the holding member itself, removing the need for chemical bonding agents and simplifying the manufacturing process.
Solution Approach 2:
The holding member is designed to automatically retain the filter through its own structural features without requiring external adhesive materials. The holding member's geometry and configuration enable it to self-secure the filter in place, making the system self-sufficient and eliminating dependency on additional bonding components.
2Reliability
If adhesive agents are used to attach the filter to the holding member, then the filter attachment becomes more fixed and secure, but the manufacturing cost increases
Solution Approach 1:
The invention removes the adhesive agent from the attachment system, eliminating the cost associated with purchasing, storing, and applying adhesive materials. The mechanical retention design relies solely on the holding member's structure, reducing material costs and simplifying the overall manufacturing expense.
Solution Approach 2:
The design employs a simple, disposable filter and holding member assembly that can be manufactured at low cost using basic materials and processes. The structural retention mechanism requires no expensive adhesive materials, making the overall system more cost-effective for single-use applications.
3Ease of manufacture
If the filter is simply placed in the holding member without additional fixation, then the production process is simple and cost-effective, but the filter attachment becomes less secure and liquid tightness is compromised
Solution Approach 1:
The holding member incorporates asymmetric structural features such as tapered surfaces or irregular geometries that enable the filter to be securely retained in a specific orientation. This asymmetric design prevents the filter from becoming dislodged while maintaining a simple manufacturing process, as the retention is achieved through the shape itself rather than complex mechanical fasteners.
Solution Approach 2:
The holding member utilizes curved or rounded structural features that create a snug fit for the filter through geometric interlocking. The curvature of the holding member's retention surfaces complements the filter's shape, providing secure attachment and liquid tightness through form-fitting geometry rather than adhesive bonding.
4Reliability
If complex fixation mechanisms are used to secure the filter, then the filter attachment becomes more secure, but the device complexity increases
Solution Approach 1:
The invention merges the functions of filter retention, structural support, and liquid tightness into a single integrated holding member design. The holding member's structure simultaneously performs multiple functions—securing the filter in place, maintaining alignment, and ensuring liquid tightness—without requiring separate fixation components, thereby reducing overall device complexity.
Solution Approach 2:
The holding member is designed as a multi-functional component that serves as both the structural framework and the fixation mechanism. Its geometry is configured to simultaneously retain the filter, maintain proper positioning, and ensure liquid tightness, eliminating the need for separate fixation devices and simplifying the overall system architecture.

AI summary
The present invention provides a filter member which comprises: a filter for discriminating cells to be analyzed in a sample from other components; a first filter holding member which comprises a first through hole and has a plate-like shape; and a second filter holding member which comprises a second through hole and is fitted into the first filter holding member. When the first and second filter holding members are integrated by fitting the second filter holding member into the first filter holding member, the filter is sandwiched between the first filter holding member and the second filter holding member, and the first through hole is opposed to the second through hole through the filter. A first elastic body is formed on a surface of the first filter holding member, the surface being in contact with the filter. A second elastic body is formed on a surface of the second filter holding member, the surface being in contact with the filter.
