Problem
Conventional medication boxes lack precision dosage sorting, scheduled reminders, and error-proof mechanisms, leading to missed, incorrect, or duplicated doses, and are often structurally complex or cost-prohibitive.
Innovation Solution
An intelligent medication dispensing box with movable inner and outer liners, split-type medication chambers, positioning magnets, Hall sensors, and a gear-rack mechanism, combined with sound and light alarms, to ensure accurate dispensing and prevent maloperation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional medication boxes are used, then storage capacity is provided, but precision dosage sorting and timed reminders are not possible
Solution Approach 1:
The medication box is divided into multiple independent compartments for different dosages and timing. Each compartment can be independently controlled and dispensed, enabling precise dosage sorting without requiring a completely complex system architecture.
Solution Approach 2:
The patent employs a servo motor-driven rotating mechanism that dynamically positions and dispenses medication compartments based on programmed timing and dosage requirements. This dynamic system allows precise control over when and what medication is dispensed, transforming a static storage box into an intelligent dispensing system.
2Extent of automation
If intelligent medication boxes with reminder functions are incorporated, then timed reminders are possible, but manufacturing cost increases
Solution Approach 1:
The control system integrates multiple functions including timed reminders, dosage tracking, and dispensing control into a single microcontroller unit. This multi-functional approach eliminates the need for separate expensive components for each function, reducing overall manufacturing costs while maintaining intelligent capabilities.
Solution Approach 2:
The system automatically tracks medication dispensing timing and dosage, providing self-service reminders and control without requiring additional manual intervention components. This automation is achieved through cost-effective sensors and control logic that monitor and manage the dispensing process independently.
3Reliability
If conventional medication boxes are used, then storage is provided, but error-proof mechanisms are lacking leading to maloperation
Solution Approach 1:
The patent incorporates sensors that detect when medication compartments are dispensed or removed, providing real-time feedback to the control system. This feedback mechanism prevents errors by tracking what has been dispensed and reminding users of upcoming doses, ensuring accurate medication intake without complicating user interaction.
Solution Approach 2:
The system pre-programs medication dispensing schedules and dosage amounts before use. By establishing the dispensing plan in advance, the system automatically prevents errors such as missed doses, incorrect timing, or wrong dosage amounts, while users simply need to load medication and receive automated guidance.
4Measurement precision
If precise medication dispensing and rotation positioning are achieved, then manufacturing cost increases, but the patent reduces cost through alternative mechanisms
Solution Approach 1:
The patent replaces expensive servo motors and complex electronic positioning systems with a simpler mechanical gear-rack mechanism driven by a stepper motor. This mechanical substitution maintains precise rotation positioning and medication dispensing accuracy while significantly reducing component costs and manufacturing complexity.
Solution Approach 2:
The medication compartments are designed as disposable or replaceable units that can be easily manufactured and replaced. This approach allows the use of simpler, lower-cost materials and manufacturing methods for the compartments themselves, while the durable positioning mechanism remains in the main body.
