Scored Tablet with Concave Face and Perpendicular Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scored tablets for veterinary use, such as those for dogs and cats, are difficult to cleave accurately due to their small size and shape, leading to inaccuracies in dividing the active substance dosage.
Innovation Solution
A scored tablet design featuring a concave lower face with perpendicular score grooves extending to the side wall, allowing for easy division into two or four identical parts by applying pressure on a convex upper face, facilitating accurate and even cleavage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tablet is made small for veterinary use, then the dosage can be adjusted for different animal weights, but the cleavage becomes difficult and inaccurate
Solution Approach 1:
The tablet is divided into four equal quadrants by two perpendicular score grooves that extend from the concave lower face through to the side walls. This segmentation allows the tablet to be easily separated into halves or quarters for dosage adjustment, while the continuous grooves ensure clean break lines even in small tablets
Solution Approach 2:
The score grooves extend into the third dimension by continuing from the lower face through the tablet thickness to the side walls. This three-dimensional scoring system creates guide lines that extend beyond the tablet surface, making it easier to apply pressure and achieve accurate cleavage in small tablets
2Strength
If the score grooves are shallow, then the tablet structure remains strong, but the cleavage accuracy decreases
Solution Approach 1:
The score grooves are pre-formed during tablet manufacturing, creating weakened lines along the desired cleavage paths. These grooves extend to the side walls to provide continuous guide lines that ensure accurate breaking, while the groove depth is optimized to maintain sufficient structural integrity for handling and administration
3Manufacturing precision
If complex shapes are used for better cleavage, then cleavage accuracy improves, but manufacturing productivity decreases
Solution Approach 1:
The tablet has a circular plan view with a concave lower face and convex upper face, providing a simple geometric shape that is easy to manufacture by compression. The perpendicular score grooves extend to the circular side walls, ensuring accurate cleavage into quarters while maintaining manufacturing efficiency through the use of basic circular geometry rather than complex shapes
