Rotatable Cassette Pill Splitter with Curved Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pill cutters fail to securely hold and accurately cut pills of varying sizes and shapes, often resulting in uneven cutting, breakage, and residue due to their universal sizing and V-shaped pill holder arrangements.
Innovation Solution
A pill splitter with a rotatable cassette having multiple pill cavities of different shapes and sizes, which securely holds pills and features a retractable blade with a curved edge for precise cutting, minimizing breakage and residue, and allows for easy selection of pill size and shape without replacing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single receptacle with V-shaped holder is used to accommodate multiple pill sizes, then the device complexity is reduced, but the manufacturing precision and cutting accuracy deteriorate
Solution Approach 1:
The single receptacle is segmented into multiple cavities of different sizes and shapes, each designed to securely hold specific pill dimensions. This segmentation allows precise accommodation of various pill types while maintaining a unified device structure, resolving the contradiction between device simplicity and cutting precision.
Solution Approach 2:
Each cavity within the receptacle is designed with local quality tailored to specific pill sizes and shapes. The cavities provide customized support surfaces and constraints for different pill types, ensuring secure positioning and accurate cutting for each local region while maintaining overall device simplicity.
2Ease of operation
If a V-shaped pill holder arrangement is used, then the ease of operation is improved, but the reliability of secure holding deteriorates
Solution Approach 1:
Each cavity is designed with specific local quality features including flat bottom surfaces, side walls, and positioning elements that match the geometry of particular pill types. This localized customization ensures reliable secure holding for each pill size and shape while maintaining ease of operation through intuitive cavity selection.
