Solution Overview

Problem

There is a need for devices that facilitate sanitary handling and disposal of used test strips, which have been exposed to potentially dangerous bodily fluids, to minimize the risk of unprotected exposure.

Innovation Solution

A test strip handling device with a housing containing an inner compartment and rollers that allow for controlled movement of test strips into the compartment for storage, with a mechanism to prevent ejection through a window and a locking mechanism to manage the rotation of rollers for efficient collection and disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If test strips are manually handled and disposed of, then the disposal process is simple, but the risk of exposure to hazardous bodily fluids increases

Engineering Contradiction:
Improverisk of exposure to hazardous fluidsVSAvoidcomplexity of handling device
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The device divides the test strip handling process into distinct functional zones: a collection area where strips are initially received, a transport mechanism with rollers that move strips through a controlled path, and a disposal compartment where strips are securely contained. This segmentation isolates the user from hazardous materials while maintaining operational simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary automated handling system that acts as a mediator between the test strips (containing hazardous fluids) and the user. The rollers, guide channels, and containment compartments serve as intermediate structures that transfer strips without requiring direct manual contact, thereby reducing exposure risk while adding controlled complexity to the disposal process

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If test strips are automatically collected and stored, then handling safety is improved, but the device complexity increases

Engineering Contradiction:
Improvesanitary handling reliabilityVSAvoidcomplexity of storage mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device integrates multiple functions into a single unified system: the same rollers and guide channels that transport test strips during operation also serve to collect and store them after use. The containment compartment serves both as a temporary storage area and as a secure disposal container. This multi-functionality achieves reliable automated handling without proportionally increasing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent employs a nested structure where the test strip is contained within a protective housing, which is in turn contained within a larger disposal compartment. The rollers and guide mechanisms are nested within the housing structure. This nesting approach enables reliable automated handling and secure containment while maintaining a compact overall device footprint

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If rollers are used to move test strips, then collection efficiency is improved, but the mechanism complexity increases

Engineering Contradiction:
Improvetest strip collection efficiencyVSAvoidcomplexity of roller mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the transport and collection functions into a single roller mechanism. The same rollers that move test strips during the testing process continue to feed strips into the disposal compartment after use. This merging of functions improves collection efficiency without requiring separate complex mechanisms for each operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The roller mechanism is designed to be dynamically adaptable - the rollers can adjust their position and movement characteristics based on whether strips are being fed from the testing area or collected for disposal. This dynamic behavior enables efficient automated handling while simplifying the overall mechanism by using a single adaptable system rather than multiple fixed mechanisms

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device ensures safe and efficient handling and storage of used test strips, reducing the risk of exposure to hazardous fluids by providing a controlled environment for their disposal.

Implementation Method 1

A first roller and a second roller may be in frictional contact with one another such that rotation of one of the rollers will cause rotation of the other
