Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional control systems are used for surgical robotic systems, then the system structure remains simple, but the ease of operation deteriorates due to insufficient input controls and lack of user-friendly operation

Engineering Contradiction:
Improveease of operationVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control system is segmented into multiple independent hand controllers, each with specialized input devices (buttons, paddles, touch input devices) positioned at different locations. This segmentation allows each controller to handle specific surgical tasks independently, improving ease of operation without requiring a single complex control interface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control interface is extended into three-dimensional space with input devices positioned on multiple surfaces (upper surface, inside side surface, outside side surface) of the contoured housing. This spatial distribution of controls across different dimensions allows the surgeon to access various functions without moving the hand controller, enhancing operational ease.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If more input controls are added to the hand controller, then the ease of operation improves, but the device complexity increases

Engineering Contradiction:
Improveuser control capabilityVSAvoidhand controller complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple types of input devices (buttons, paddles, touch input devices) are merged into a single integrated hand controller with a contoured housing. This consolidation provides diverse input capabilities in one unit, improving user control without requiring multiple separate control devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hand controller is designed as a multi-functional device where different input devices (first button, second button, first touch input device, first paddle, second paddle) can perform various surgical control functions. This universality allows a single controller to handle multiple operational tasks, reducing the need for multiple specialized controllers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the hand controller is designed with contoured housing for ergonomic grasping, then the ease of operation improves, but the manufacturing complexity increases

Engineering Contradiction:
ImproveergonomicsVSAvoidhousing manufacturing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The housing is designed with contoured surfaces including an upper surface, inside side surface, and outside side surface that conform to the natural shape of the surgeon's hand. These curved surfaces enable ergonomic grasping with thumb, fingers, and palm, improving ease of operation during prolonged surgical procedures.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

Systems and methods employing at least one hand controller for controlling a robotic assembly of a surgical robotic system are provided. The hand controller may be used in a surgeon console of a surgical robotic system. The hand controller may include a contoured housing having an upper surface, an inside side surface adjacent the upper surface, an outside side surface facing away from the first side surface, and a lower surface facing away from the upper surface. The hand controller may include a plurality of buttons including a first button positioned on the upper surface and a second button positioned on one of the upper surface, the inside side surface, or the outside side surface; a first touch input device positioned on the upper surface; and a first paddle mounted to either of the inside side surface or the outside side surface.
