Automated Glucose Test Device Consumable Dispensing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glucose test devices require users to manually install and replace lancets and test strips, leading to complex installation steps and potential for bacterial infections due to repeated use, causing inconvenience and safety concerns.
Innovation Solution
A glucose test device with a carrying unit that automatically dispenses and replaces lancets and test strips using a locking mechanism controlled by a driving unit and control unit, preventing accidental lancet firing and enhancing user safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual installation and replacement of lancets and test strips is used, then the device structure is simple, but the operation process becomes complex and inconvenient
Solution Approach 1:
The carrying unit pre-stores multiple lancets and test strips in ready-to-use positions. The automated pushing mechanism is activated in advance to deliver the next consumable before the current one is fully used, eliminating the need for manual installation during the testing process.
Solution Approach 2:
The device performs self-service by automatically pushing lancets and test strips from the carrying unit to the operational position using the first and second pushing units. This automated consumable delivery system eliminates manual intervention, allowing the device to service itself during operation.
2Reliability
If manual replacement of consumables is allowed, then the device structure is simple, but the risk of bacterial infection increases
Solution Approach 1:
The manual mechanical operation of installing and replacing lancets and test strips is replaced with an automated electromechanical pushing system. The control unit manages the automated delivery, ensuring that only sterile, single-use consumables are deployed, thereby preventing bacterial infection while reducing the need for complex manual handling procedures.
Solution Approach 2:
The control unit monitors the status of consumables in the carrying unit and automatically activates the pushing units when lancets or test strips need replacement. This feedback-controlled system ensures that consumables are replaced at the appropriate time without manual intervention, maintaining sterility and preventing infection.
3Object-affected harmful factors
If automated locking mechanism is added, then the safety is improved, but the device complexity increases
Solution Approach 1:
The locking component acts as an intermediary safety mechanism between the first pushing unit and the lancet. It controls the release of the lancet by requiring proper alignment and activation conditions, preventing accidental firing while allowing controlled deployment when needed. The control unit manages the locking component's state to ensure safe operation.
4Ease of operation
If automated consumable delivery is implemented, then the operation convenience is improved, but the device complexity increases
Solution Approach 1:
The automated delivery system is segmented into separate functional units: the carrying unit stores consumables, the first pushing unit delivers lancets, and the second pushing unit delivers test strips. Each unit operates independently under control of the control unit, simplifying the overall system architecture while maintaining automated functionality for convenient operation.
