Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple stages with different specifications are used to hold optical calibration cards, product information cards, and different types of rapid test reagent cards, then the analyzing apparatus can handle various card types, but the production cost increases

Engineering Contradiction:

Improveability to handle various card typesVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The integrated stage is designed with a universal structure that can hold multiple types of cards (optical calibration cards, product information cards, and different types of rapid test reagent cards) through a single standardized interface. The stage includes receiving spaces with adjustable elastic sheets that adapt to different card dimensions, eliminating the need for multiple specialized stages and reducing production costs while maintaining versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The integrated stage is divided into multiple receiving spaces (first receiving space, second receiving space, third receiving space) that can independently hold different card types. Each receiving space can be independently configured with elastic sheets of different dimensions, allowing the stage to handle various card formats simultaneously through a single unified structure

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple stages with different specifications are used, then different card types can be held, but the device complexity increases

Engineering Contradiction:

Improveability to hold different card typesVSAvoidnumber of stages

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple stages that were previously used to hold different card types are merged into a single integrated stage. The integrated stage combines multiple receiving spaces into one unified structure, reducing the total number of stages from multiple to one, thereby simplifying the device while maintaining the ability to hold various card types

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If qualitative detection is performed by naked eyes, then the detection process is simple, but the results are affected by environmental influences or human misjudgment

Engineering Contradiction:

Improvesimplicity of detection processVSAvoidaccuracy of detection results

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical/visual detection system (naked eye observation) with an optical detection system. The integrated stage is designed to work with an analyzing apparatus that uses optical principles to perform concentration analysis on the rapid test reagent cards, substituting human visual judgment with automated optical measurement to eliminate environmental influences and human misjudgment while maintaining operational simplicity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An integrated stage for holding rapid test reagent cards includes two U-shaped sidewalls opposite to each other, a first receiving space, a second receiving space, and an elastic sheet. The U-shaped sidewalls cooperatively define the first receiving space. The second receiving space is formed in the first receiving space and is lower than the first receiving space. The elastic sheet is arranged on a short side of the first receiving space. The first receiving space is used for allowing the integrated stage to hold a first rapid test reagent card. The second receiving space is used for allowing the integrated stage to hold a second rapid test reagent card. The integrated stage utilizes the elastic sheet to hold and fix the first rapid test reagent card or the second rapid test reagent card.
