Retractable Inhaler Mouthpiece for Hygiene and Powder Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inhalers face challenges such as difficulty in replacing capsules, potential contamination of the mouthpiece, unintended leakage of functional material powder, and inadequate inhalation resistance, which affect hygiene and aesthetics.
Innovation Solution
The inhaler design includes a retractable mouthpiece mechanism, a cap for easy capsule replacement, and a filter system to prevent contamination and leakage, while maintaining sufficient inhalation resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mouthpiece is always exposed for easy access, then ease of operation is improved, but hygiene deteriorates due to potential contamination
Solution Approach 1:
The mouthpiece is designed to be movable between extended and retracted positions. When not in use, the mouthpiece retracts into the housing to be protected from contamination. When needed, it can be extended for use. This dynamic positioning resolves the contradiction between accessibility and hygiene protection.
2Reliability
If the capsule is permanently fixed, then reliability is improved, but ease of operation deteriorates due to difficulty in replacement
Solution Approach 1:
The capsule assembly is designed as a separable module that can be easily detached from the housing. The capsule holder and capsule form a removable unit that can be quickly replaced without affecting the structural integrity of the main inhaler body. This segmentation allows for easy replacement while maintaining reliable connection during use.
3Ease of operation
If the needle is always exposed for functional access, then ease of operation is improved, but object-generated harmful factors worsen due to contamination risk
Solution Approach 1:
The needle is integrated with the movable mouthpiece assembly, allowing it to be extended and retracted together. When the mouthpiece retracts into the housing, the needle is automatically protected within the housing cavity, preventing contamination while maintaining access when needed.
4Volume of moving object
If the inhaler is designed for compact storage, then volume is reduced, but ease of operation deteriorates due to limited access to components
Solution Approach 1:
The mouthpiece is nested within the housing when not in use, and the capsule holder is integrated into the housing structure. This nesting arrangement allows the inhaler to maintain a compact form factor while providing easy access to the mouthpiece and capsule through designated openings and removable components.

AI summary
An inhaler accommodates a capsule including a functional material and includes a housing including a first end that is open, a mouthpiece, at least a portion of which protrudes from the first end, a needle coupled to the mouthpiece and extending toward a capsule accommodated in the housing, and a retracting mechanism for inserting the mouthpiece into the housing, and the retracting mechanism changes a position of the mouthpiece between a first state in which at least a portion of the mouthpiece protrudes from the first end and a second state in which the mouthpiece is inserted into the housing.
