Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If multiple steps and solutions are used for detecting intracellular bacterial enzymes, then detection accuracy can be maintained, but the process becomes time-consuming and inefficient

Engineering Contradiction:
Improvedetection timeVSAvoidnumber of preparation steps
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent combines multiple separate reagents (lysis buffer and detection reagent) into a single integrated dry composition that contains both components in predetermined amounts. This merging eliminates the need for separate preparation steps and reduces detection time while maintaining detection accuracy through optimized reagent combinations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary action by pre-drying and pre-formulating the reagents into a stable dry composition before use. This preliminary preparation allows the reagents to be stored stably and eliminates the need for on-site preparation of multiple solutions, directly reducing the time and complexity of the detection process.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If reagents are kept in dried form, then stability at room temperature is improved, but the complexity of handling and reconstitution may increase

Engineering Contradiction:
Improvereagent stabilityVSAvoidhandling complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent applies parameter changes by transitioning reagents from liquid to dry form, which fundamentally changes their storage and handling parameters. This parameter change enables room temperature stability while the formulation includes all necessary components pre-measured, simplifying the reconstitution step to a single mixing action.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If a one-step process is implemented, then productivity increases, but the requirement for precise reagent formulation and stabilization becomes more critical

Engineering Contradiction:
Improvedetection efficiencyVSAvoidreagent formulation precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary action by pre-formulating and pre-drying the reagents with precise measurements during manufacturing. This preliminary precision work is embedded into the dry composition, allowing the final one-step detection process to achieve high productivity without requiring precision during the actual detection operation.

Inventive Principle:
Principle #10Preliminary action
