Solution Overview

Problem

Existing robotically assisted surgical systems suffer from ergonomically inferior and bulky surgeon consoles, leading to fatigue during long procedures and difficulty in shifting the console between operating rooms.

Innovation Solution

A hand controller assembly with motorized joint assemblies and a gimbal mechanism that allows for ergonomic movement in x, y, and z-axes, featuring a dovetail mount for easy attachment to the console system, enhancing mobility and ergonomics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional console designs are used, then structural stability is maintained, but ergonomics deteriorate causing surgeon fatigue

Engineering Contradiction:
ImproveergonomicsVSAvoidconsole structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The hand controller incorporates motorized joint assemblies that enable dynamic adjustment of the controller's position and orientation in x, y, and z-axes. This allows the console to adapt to different surgeon preferences and surgical tasks, improving ergonomics while maintaining structural stability through controlled motorized movement rather than static rigid structures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The console structure is divided into modular components including the hand controller assembly, motorized joint assemblies, and dovetail mount system. This segmentation allows independent optimization of each module for ergonomics while maintaining overall system stability through standardized interfaces and mounting mechanisms.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If traditional bulky console designs are used, then structural stability is maintained, but mobility deteriorates making shifting difficult

Engineering Contradiction:
ImprovemobilityVSAvoidconsole structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dovetail mount system enables the hand controller assembly to be dynamically mounted and dismounted from the console structure. This provides ease of relocation between operating rooms while maintaining structural stability during use through secure engagement of the dovetail mechanism with the mounting plate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The dovetail mount acts as an intermediary mechanism between the hand controller assembly and the console structure. It provides a standardized interface that facilitates easy attachment and detachment while ensuring stable operation when mounted, resolving the contradiction between mobility and structural stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If motorized joint assemblies are added for ergonomic movement, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improvecontroller adjustabilityVSAvoidhand controller assembly
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The motorized joint assemblies are designed with universal mounting interfaces and standardized components that can be integrated into the hand controller assembly. Each joint assembly provides multi-axis movement capability, reducing the total number of components needed while achieving comprehensive ergonomic adjustment.

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

Solution Approach 2:

Multiple functional elements are merged into integrated assemblies - the motorized joint assemblies combine drive mechanisms, mounting interfaces, and control systems into unified modules. This merging reduces overall system complexity compared to having separate components for each function.

Inventive Principle:
Principle #5Merging (Combining)
