Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple access ports are used for robotic surgical systems, then surgical capability and mobility are improved, but patient trauma and procedural complexity increase

Engineering Contradiction:

Improvesurgical capabilityVSAvoidpatient trauma

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple surgical instruments and a camera system into a single integrated robotic device that accesses the surgical site through one port. This merging of functions allows the device to perform multiple surgical tasks while minimizing patient trauma by avoiding multiple access ports.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The robotic device is designed with universal multi-functionality, incorporating various surgical tools and imaging capabilities in a single platform. This allows the device to adapt to different surgical procedures and requirements while maintaining a single access point, thereby improving surgical capability without increasing patient trauma.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If rigid tools are used in minimally invasive surgery, then structural stability is improved, but mobility and maneuverability are restricted

Engineering Contradiction:

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent employs dynamic articulated arms with multiple degrees of freedom that can be precisely controlled during surgery. These arms provide both structural stability when needed and enhanced mobility and maneuverability when required, allowing the surgical tools to reach difficult-to-access areas while maintaining operational precision.

Inventive Principle:

Solution Approach 2:

The robotic device is segmented into multiple articulated components with independent control. This segmentation allows each segment to move and position itself optimally, providing both stability for precise surgical actions and mobility for navigating complex anatomical structures.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If a single access port is used, then patient trauma is minimized, but device complexity and insertion difficulty increase

Engineering Contradiction:

Improvepatient traumaVSAvoiddevice complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent utilizes a nested configuration where multiple surgical instruments and a camera system are housed within a single robotic device structure. This nesting allows all necessary components to be delivered through one access port, minimizing patient trauma while managing device complexity through integrated design.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The robotic device employs articulated arms with multiple degrees of freedom that operate in three-dimensional space. This dimensional capability allows the device to navigate and position instruments within the surgical site through a single port, effectively managing complexity through spatial manipulation rather than requiring multiple access points.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Device complexity
