Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a replaceable flow tract system is implemented, then contamination and residue buildup on permanent components is reduced, but device complexity increases
Solution Approach 1:
The flow tract is divided into replaceable and permanent segments. The replaceable flow tract portion can be detached and discarded after use, preventing contamination and residue buildup on the permanent components of the inhaler device. This segmentation allows the permanent housing and mechanism to remain clean while the disposable portion absorbs all contact with the active substance.
Solution Approach 2:
The flow tract is designed as a disposable component that is replaced after a single use or after a predetermined number of uses. This eliminates the need to clean and maintain the flow tract permanently, reducing contamination risks and ensuring consistent performance throughout the product's lifecycle.
2Reliability
If an elastic sealing member is used to seal the construct, then substance delivery isolation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The sealing member transitions from a rigid seal to an elastic seal that can deform and adapt to the construct's surface. This elasticity allows the sealing member to compensate for minor variations in construct positioning and surface irregularities, achieving reliable substance delivery isolation without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The elastic sealing member functions as a flexible element that conformally seals around the construct. This flexibility enables the sealing member to maintain effective contact and prevent substance leakage even when there are slight variations in the construct's position or shape, reducing the need for high-precision manufacturing.
3Reliability
If locking elements are added to secure the flow tract, then reliability of connection is improved, but ease of operation decreases
Solution Approach 1:
The locking mechanism is designed to be dynamically engageable and disengageable. During insertion, the locking elements automatically engage with the housing to secure the flow tract firmly in place, ensuring reliable connection. During removal, the locking elements can be easily released through a simple user action, restoring ease of operation. This dynamic behavior allows the system to provide strong connection during use while remaining simple to replace.
