Ophthalmology Handle Grip Segmentation and Color Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held medical devices in ophthalmology have difficulty being cleaned due to roughened surfaces and lack both effective grip and identification features, making them cumbersome and difficult to use.
Innovation Solution
The device incorporates grip-enhancing holding areas on the handle that also serve as a coding system using color and haptic feedback to identify the tool, allowing for easy cleaning and improved handling, with the option of interchangeable heads equipped with similar features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire handle surface is corrugated or roughened to improve grip, then the grip is improved, but cleaning the device becomes more difficult
Solution Approach 1:
The handle surface is divided into distinct holding areas with different surface qualities. Some areas are roughened or corrugated to provide grip, while other areas remain smooth to facilitate cleaning. This segmentation allows the device to have both good grip characteristics and ease of cleaning without requiring the entire surface to be roughened.
2Ease of operation
If the entire handle surface is corrugated or roughened to improve grip, then the grip is improved, but the device lacks orientation aids for grasping
Solution Approach 1:
Different areas of the handle are given different surface qualities and characteristics. The holding areas have specific roughness or corrugation patterns that not only provide grip but also create haptic feedback for orientation. This local differentiation allows the device to convey grasping orientation information through tactile sensation without requiring uniform roughening of the entire surface.
3Ease of operation
If the entire handle surface is corrugated or roughened to improve grip, then the grip is improved, but the device lacks identification features
Solution Approach 1:
The holding areas are provided with color coding to identify the device or the tool carried by the hand-held device. Different colors or color patterns on the holding areas serve as visual identification features, allowing users to quickly recognize the device type or function without requiring the entire handle to be uniformly colored or patterned.
