Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dry powder inhalers (DPIs) are ineffective in delivering medication to the peripheral parts of the lung, are aesthetically unpleasing, and have mouthpieces that do not fit comfortably, leading to suboptimal medication delivery and user discomfort.
Innovation Solution
A compact, cigarette-shaped inhalation device with a mouthpiece, drug chamber, and air flow chamber connected via a twisted or flapped close/open mechanism, ensuring precise and efficient delivery of dry powder medication to the lung periphery, allowing for repeated use and increased compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional DPI design is used, then medication delivery function is provided, but medication cannot reach peripheral lung parts effectively and device appearance is unappealing
Solution Approach 1:
The device is segmented into distinct functional modules: mouthpiece assembly, drug chamber with multiple compartments for different medications, airflow control mechanisms, and filtration system. This segmentation allows each component to be optimized for its specific function while contributing to overall medication delivery effectiveness to peripheral lung regions.
Solution Approach 2:
The patent introduces a multi-dimensional approach to medication delivery by incorporating both aerosolization and powder delivery mechanisms simultaneously, creating a dual-mode delivery system that can reach different lung regions through different particle trajectories and deposition patterns.
2Device complexity
If mouthpiece design does not fit perfectly, then device simplicity is maintained, but medication cannot be fully inhaled and delivery precision is reduced
Solution Approach 1:
The mouthpiece incorporates dynamic sealing elements and adjustable components that adapt to different user anatomies. The sealing mechanism dynamically adjusts during inhalation to ensure complete medication uptake regardless of individual mouthpiece-fit variations, maintaining both simplicity and precision.
3Ease of operation
If single puff inhalation is used, then device operation is simple, but not all medication can be inhaled and waste occurs
Solution Approach 1:
The device enables continuous inhalation action through multiple puffs from a single loaded chamber. The airflow control system maintains continuous medication availability throughout the inhalation sequence, allowing complete utilization of the medication dose across multiple breaths rather than losing unused medication after a single puff.
4Ease of manufacture
If device is not cigarette-shaped, then manufacturing is simpler, but patient compliance in public places decreases
Solution Approach 1:
The cigarette-shaped device incorporates multiple medication compartments that can be loaded with different medications or dosages, making it universally applicable for various treatment regimens while maintaining the discreet form factor needed for public use compliance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively delivers medication to the peripheral lung areas, providing a comfortable and discreet means of inhalation, ensuring all medication is inhaled and increasing compliance by mimicking a cigarette, thereby enhancing medication delivery precision and convenience.
Implementation Method 1
The twisted close/open mechanism includes two surfaces with at least one opening on each surface, and the process of aligning the at least one opening by twisting provides an open flow condition and unaligned to block the at least one opening by twisting provides a close flow condition.
Implementation Method 2
the flapped flow close/open mechanism includes two surfaces with an opening on a first surface of the two surfaces and a flap on a second surface of the two surfaces to close or open a flow through the opening.
Implementation Method 3
A design as a cigarette may also stimulate suction and lips easily adapt mouthpiece of cigarette and instantly synchronize suction of powder medication

AI summary
The invention provides a compact inhalation device (CID) to effectively deliver inhalation mediation to a patient. The CID comprises a mouth piece, a drug chamber and an air flow chamber, wherein the mouth piece, the drug chamber and the air flow chamber are connected to form a cylinder-shaped device, which is similar to a cigarette, and provide at least medication contained in the drug chamber to the patient via the mouth piece. One end of the mouth piece fits a patient's mouth. The other end of the mouth piece is connected to a first end of the drug chamber, and a second end of the drug chamber is connected to a first end of the air flow chamber, wherein the connections between them use a twisted close/open mechanism or a flapped flow close/open mechanism. A second end of the air flow chamber has an opening for ambient air flow.
