Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple robotic arms are used to manipulate scope and instruments, then surgical functionality is improved, but collision risk between arms increases
Solution Approach 1:
The patent introduces a vertical dimension by implementing adjustable arm supports with multiple degrees of freedom including vertical translation. This allows robotic arms to be positioned at different heights, separating their operational planes and reducing collision risk while maintaining multiple arms for comprehensive surgical functionality
Solution Approach 2:
The arm supports are designed to be dynamically adjustable during procedures, allowing real-time repositioning of robotic arms. This dynamic capability enables the system to adapt arm positions to avoid collisions while maintaining optimal surgical triangulation and functionality
2Ease of operation
If robotic arms are positioned to reach desired surgical locations, then surgical accessibility is improved, but triangulation between arms becomes difficult to achieve
Solution Approach 1:
The adjustable arm support structure serves multiple functions simultaneously: it enables vertical translation for height adjustment, lateral translation for horizontal positioning, tilt for angular orientation, and horizontal swing for rotational movement. This multi-functionality allows a single support system to achieve both surgical accessibility and proper triangulation configuration
Solution Approach 2:
The arm support system is segmented into multiple independently adjustable components with five degrees of freedom. Each segment can be adjusted separately to optimize the position of robotic arms, enabling independent control over height, lateral position, tilt angle, and horizontal orientation to achieve precise triangulation
3Device complexity
If fixed arm support configuration is used, then system simplicity is maintained, but external workspace optimization is limited
Solution Approach 1:
The system transitions from a fixed arm support configuration to a dynamic, multi-degree-of-freedom adjustable support system. This allows the external workspace to be optimized for different surgical procedures and patient anatomies while maintaining relative system simplicity through standardized adjustable components

AI summary
A robotic surgical system may include a table and at least one adjustable arm support that supports one or more robotic arms. The adjustable arm support may be capable of swinging horizontally in a direction of the table. A plate extension may extend outward from the adjustable arm support. An extender bar may be coupled to one or more of the robotic arms and a cannula. A height differential may be provided between a first robotic arm and a second robotic arm that is supported on the adjustable arm support.
