Test Device Retaining Member for Sample Applicator Footprint Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic test devices with separate sample applicators face issues of increased bulkiness and inefficient packaging due to the applicator's presence, which can hinder packaging processes and risk damage during transportation.
Innovation Solution
The test device incorporates retaining members that allow the sample applicator to be removably retained within the housing, minimizing the overall footprint and preventing the applicator from extending beyond the device's boundaries, thus enhancing packaging efficiency and protecting against damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sample applicator is packaged separately or retained on the side of the test device, then the applicator is accessible for use, but the overall footprint of the product increases and packaging efficiency decreases
Solution Approach 1:
The sample applicator is retained within a retaining member that is integrated into the housing of the test device, with the applicator nested inside the housing boundaries. This nesting arrangement allows the applicator to be stored compactly within the device footprint while remaining accessible for use, thereby resolving the contradiction between accessibility and footprint size.
Solution Approach 2:
The retaining member is merged with the housing structure, creating an integrated assembly where the applicator, retaining member, and housing form a unified compact unit. This merging eliminates the need for separate applicator packaging or side-mounted retention, reducing the overall product footprint while maintaining operational accessibility.
2Ease of operation
If a sample applicator is retained on the side of the test device, then the applicator is available for use, but packaging processes become inefficient and the risk of damage during transportation increases
Solution Approach 1:
The applicator is nested within the housing boundaries through the retaining member, creating a protected internal storage configuration. This nesting provides physical protection during transportation while maintaining accessibility for use, thereby improving reliability without compromising ease of operation.
Solution Approach 2:
The integration of the retaining member with the housing creates a unified protected structure that safeguards the applicator during packaging and transportation. This merged design eliminates the vulnerability of side-mounted applicators while preserving their availability for use.
