Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If video fluoroscopic swallowing study apparatus or fiberoptic endoscopic evaluation of swallowing apparatus is used, then measurement precision of dysphagia is improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvedysphagia measurement precisionVSAvoidapparatus complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the complex swallowing evaluation system into separate functional modules: oral cavity sensor, pharyngeal cavity sensor, and measurement unit. Each module performs a specific function, allowing the system to achieve comprehensive measurement precision without requiring a single complex apparatus like VFSS or FEES.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces the mechanical/optical systems of VFSS (X-ray fluoroscopy) and FEES (fiberoptic endoscopy) with electrical sensing systems. Sensors detect swallowing parameters electrically and physiologically, eliminating the need for expensive, complex imaging equipment while maintaining measurement precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If video fluoroscopic swallowing study apparatus is used, then anatomical structure confirmation is improved, but exposure to radiation occurs

Engineering Contradiction:
Improveanatomical structure confirmationVSAvoidradiation exposure
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes the X-ray fluoroscopy system with electrical and physiological sensing systems. Sensors placed in the oral and pharyngeal cavities detect swallowing movements and anatomical structures through electrical signals and physiological parameters, completely eliminating radiation exposure while maintaining the ability to confirm anatomical structures.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If fiberoptic endoscopic evaluation of swallowing apparatus is used, then inner structure observation is improved, but invasive method is required

Engineering Contradiction:
Improveinner structure observationVSAvoidinvasiveness
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the invasive fiberoptic endoscope with non-invasive electrical sensors. These sensors detect inner structure movements and swallowing parameters through electrical signals generated by muscle contractions, eliminating the need to insert physical instruments into the patient's body while maintaining observation precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Measurement precision

If known dysphagia measurement apparatus is used, then measurement capability is improved, but portability and ease of use in small-scale hospitals deteriorate

Engineering Contradiction:
Improvedysphagia measurement capabilityVSAvoidportability and ease of use
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent divides the measurement system into small, portable sensor units that can be easily transported and set up in small-scale hospitals. Each sensor unit is independent and can be attached to specific body parts, making the system highly portable while maintaining comprehensive measurement capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the essential measurement functions from large, fixed hospital equipment and implements them through small, portable sensor units. This extraction allows the system to maintain measurement precision while being easily deployable in various healthcare settings, including small-scale hospitals and home care environments.

Inventive Principle:
Principle #2Taking out (Extraction)

5Ease of operation

If examination time is shortened for practical use, then ease of operation is improved, but measurement precision of swallowing characteristics deteriorates

Engineering Contradiction:
Improveexamination timeVSAvoiddysphagia characteristic detection
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements continuous monitoring during the swallowing process using multiple sensors that simultaneously detect various parameters. This continuous data collection allows for rapid analysis and accurate detection of swallowing characteristics without requiring extended examination time, as all relevant data is captured concurrently rather than sequentially.

Inventive Principle:
Principle #20Continuity of useful action
