Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry powder inhaler devices require multiple steps for operation, making them cumbersome and inefficient for dispensing medicaments from multiple carriers.
Innovation Solution
A medicament dispenser with a simplified mechanism that allows for single-handed operation, featuring a dispensing mechanism with fewer moving components, enabling independent advancement and simultaneous or sequential dispensing of medicament carriers with a flow director to direct airflow and separate waste collectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional multi-step operation mechanism is used in dry powder inhalers, then the dispensing mechanism can reliably advance and dispense medicament, but the ease of operation deteriorates due to requiring multiple steps and complex hand coordination
Solution Approach 1:
The cover is pre-configured with a cam mechanism that automatically performs the medicament carrier advancement action when the user simply opens and closes the cover. The cam profile is designed so that during the closing motion, the cam surface guides and actuates the carrier engagement component to advance the carrier, eliminating the need for separate manual advancement steps.
Solution Approach 2:
The cam mechanism on the cover works in conjunction with the carrier engagement component to automatically advance the medicament carrier without requiring additional user input. The system uses the natural closing motion of the cover to self-actuate the carrier advancement, making the operation intuitive and reducing the number of steps required.
2Productivity
If multiple medicament carriers are dispensed simultaneously, then productivity increases, but device complexity increases due to requiring coordinated advancement mechanisms for multiple carriers
Solution Approach 1:
A single cam mechanism on the cover is designed to simultaneously actuate multiple carrier engagement components through its profile geometry. The cam surface is shaped so that one rotational movement automatically coordinates the advancement of multiple medicament carriers in parallel, allowing a single user action to control multiple dispensing functions without requiring separate control mechanisms for each carrier.
Solution Approach 2:
The invention combines the advancement control of multiple medicament carriers into a single integrated cam mechanism. Instead of having independent actuators for each carrier, the cam profile merges the actuation functions, allowing all carriers to be advanced simultaneously through one coordinated motion generated by the cover closing action.
3Device complexity
If the cover is directly connected to the lever mechanism, then device complexity is reduced, but ease of operation deteriorates because the user must perform multiple sequential steps
Solution Approach 1:
The cam mechanism is pre-formed on the cover with a specific profile that encodes the advancement motion of the medicament carrier. This preliminary geometric configuration allows the cover's simple opening and closing motion to automatically translate into the correct carrier advancement sequence, eliminating the need for complex direct mechanical connections while maintaining ease of operation.
