Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional console-based system with tower PC, monitor, keyboard, and mouse is used, then the system provides comprehensive data processing and display capabilities, but the system becomes heavy, immobile, and time-consuming to set up

Engineering Contradiction:

Improvemobility and setup timeVSAvoidsystem configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (controller core, computing core, ADC, signal conditioning circuit, and display) into a single integrated handheld interface device. This merging eliminates the need for multiple separate devices connected by cables, directly resolving the contradiction by making the system portable while maintaining all necessary processing and display functions within one unified device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handheld interface device is designed to perform multiple functions: it controls the intraluminal device, processes physiological data, converts analog signals to digital, conditions signals, and displays graphical representations. This multi-functionality allows a single device to replace the entire conventional console system, improving mobility while maintaining comprehensive operational capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If numerous lengthy cables and large consoles are used to connect the intraluminal device, then data transmission and power supply are ensured, but user flexibility and workflow efficiency are reduced

Engineering Contradiction:

Improveworkflow efficiencyVSAvoiduser flexibility

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent extracts the interface functionality from the intraluminal device and places it in a separate handheld interface device. This extraction eliminates the need for lengthy cables and large consoles, allowing the user to hold and move the interface device freely during procedures, thereby improving both workflow efficiency and user flexibility.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The handheld interface device is designed to be dynamically movable and repositionable during medical procedures, unlike fixed console systems. The device can be easily moved to different locations and angles, providing dynamic adaptability that enhances user flexibility and procedural efficiency.

Inventive Principle:

Principle #15Dynamics

3Weight of moving object

If a handheld interface device with integrated components is used, then mobility and setup time are improved, but the device must house multiple functional components in a compact form

Engineering Contradiction:

Improvedevice portabilityVSAvoidcomponent integration

Core Design Contradiction:

Weight of moving objectVSDevice complexity

Solution Approach 1:

The patent implements a nested structure where the controller core, computing core, ADC, signal conditioning circuit, and display are housed within the housing of the handheld interface device. This nesting arrangement allows multiple functional components to be compactly integrated, reducing the overall device size and weight while maintaining all necessary functionalities.

Inventive Principle:

Principle #7Nested doll (Nesting)
