Solution Overview
Problem
In dental and medical treatments, medical apparatuses are difficult to accurately position and fix for extended periods, especially when used by assistants or attached to instruments, leading to inefficiencies in treatment processes.
Innovation Solution
A treatment assistance apparatus with a multi-joint robot arm structure, including a base, joints, and a controller, that allows for precise positioning and fixation of medical apparatuses using driving parts, sensors, and pressure systems to adapt to various treatment environments and patient positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If medical apparatuses are used by assistant personnel or attached to simple instruments, then the apparatuses can be operated during treatment, but it becomes difficult to fix the apparatuses in an accurate position for a long time
Solution Approach 1:
The apparatus is divided into multiple independent components: a base unit, a movable arm assembly with multiple segments, and a medical apparatus mounting unit. This segmentation allows the mounting unit to be independently positioned and secured, achieving both ease of operation and position stability.
Solution Approach 2:
A movable arm assembly acts as an intermediary between the base and the medical apparatus. This intermediary component provides adjustable positioning capabilities and secure mounting mechanisms, enabling assistant personnel to easily position and fix the medical apparatus at desired locations.
2Ease of operation
If the medical apparatus is attached to an instrument, then it can be used during treatment, but it becomes difficult to position the medical apparatus at a desired position and not easy to change the position
Solution Approach 1:
The arm assembly incorporates movable joints and adjustable components that enable dynamic repositioning. The medical apparatus can be easily moved to different positions along the arm's range of motion and secured at any desired location, providing both usability during treatment and position adjustability.
Solution Approach 2:
The system allows changing of positional parameters through the movable arm mechanism. Assistant personnel can adjust the arm's extension, angle, and height parameters to position the medical apparatus at various desired locations, then secure it in place.
3Measurement precision
If a multi-joint robot arm structure is used for precise positioning, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The complex positioning system is segmented into modular components: base unit, arm assembly with defined joints, and mounting unit. Each segment has a specific function, making the overall complex system manageable and easier to operate while maintaining positioning accuracy.
Solution Approach 2:
The multi-joint arm structure serves multiple functions: positioning, supporting, and securing the medical apparatus. This universal design achieves precise positioning without requiring additional separate components, thereby managing complexity through functional integration.
