Solution Overview
Problem
Existing tablet testing devices face challenges in efficiently and automatically measuring properties like length, width, breaking strength, and weight, especially when dealing with tablets of different shapes and sizes, often requiring complex and costly structures for alignment and positioning.
Innovation Solution
A device featuring a turntable with adaptable positioning grooves that aligns tablets by gravity, allowing for quick and error-free measurement, and includes a movable support surface for easy switching between different test specimens, along with a cleaning mechanism for fragments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual placement of tablets in test stations is used, then positioning accuracy can be achieved, but productivity is low and time consumption is high
Solution Approach 1:
The tablet automatically aligns itself in the positioning groove through gravity and geometric constraints without requiring manual intervention or complex alignment mechanisms. The V-shaped groove design enables the tablet to self-position correctly during automated conveyance
Solution Approach 2:
The positioning groove is designed in advance with specific geometric features (V-shape cross-section, inclined sides) that pre-establish the correct orientation and position of the tablet before it reaches the measurement station, eliminating the need for real-time alignment adjustments
2Adaptability or versatility
If complex alignment mechanisms like image recognition or rotating transport stars are used, then tablets of different shapes and sizes can be positioned correctly, but device complexity and cost increase
Solution Approach 1:
The positioning groove with V-shaped cross-section and inclined sides serves multiple functions: it guides tablets of various shapes and sizes, automatically orients them correctly, and positions them for measurement all through a single passive geometric structure, eliminating the need for multiple active alignment mechanisms
Solution Approach 2:
The positioning groove dimensions (width, depth, angle) can be adjusted or modified to accommodate different tablet specifications, allowing the same simple structure to adapt to various tablet shapes and sizes without requiring complex reconfiguration mechanisms
3Measurement precision
If fixed positioning structures are used, then alignment accuracy is maintained, but cleaning becomes difficult and time-consuming
Solution Approach 1:
The positioning groove is designed with smooth, continuous surfaces and no dead corners or recesses where debris could accumulate. The V-shaped geometry with inclined sides allows for easy runoff of particles and simplifies cleaning operations while maintaining precise alignment functionality
