Solution Overview
Problem
Electronic vapor devices face challenges in efficiently utilizing and extending the shelf-life of pre-vapor formulations due to leakage and inefficient release mechanisms.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hermetically-sealed supply packet is used to store pre-vapor formulation, then leakage is prevented and shelf-life is extended, but the mechanism to release the formulation becomes more complex
Solution Approach 1:
The supply packet is pre-filled and hermetically sealed before use, with the formulation already in the correct container. The packet includes pre-positioned features such as the collapsed accordion sidewalls and the puncture-release mechanism that is ready to activate when the mouthpiece is pressed, eliminating the need for complex assembly or multiple components during operation.
Solution Approach 2:
The hermetically-sealed supply packet acts as an intermediary between the storage reservoir and the vaporization chamber. It provides a reliable barrier that prevents leakage while allowing controlled release through a simple puncture mechanism activated by the mouthpiece, simplifying the overall system architecture.
2Ease of operation
If a puncture device is used to pierce the supply packet for release, then controlled discharge is achieved, but the structural complexity increases
Solution Approach 1:
The puncture function is extracted as a separate, dedicated feature within the housing shell, distinct from the mouthpiece structure itself. This allows the mouthpiece to remain simple while the puncture device provides the specialized function of piercing the supply packet when activated by mouthpiece movement.
Solution Approach 2:
The supply packet's accordion sidewalls are designed to collapse automatically when the mouthpiece transitions to the retracted position, creating the necessary pressure and alignment for the puncture device to pierce and discharge the formulation without requiring additional actuating mechanisms or complex control systems.
3Productivity
If accordion sidewalls are used to collapse when mouthpiece retracts, then efficient formulation discharge is achieved, but manufacturing complexity increases
Solution Approach 1:
The supply packet incorporates accordion-shaped sidewalls made from flexible material that can be molded or formed during the packet manufacturing process. This flexible structure allows the packet to collapse efficiently when pressure is applied during mouthpiece retraction, enabling complete and controlled discharge of the pre-vapor formulation without requiring mechanical moving parts.
4Reliability
If the mouthpiece transitions irreversibly to retracted position, then consistent vapor production is ensured, but the device becomes less adaptable
Solution Approach 1:
The mouthpiece assembly is segmented into distinct functional zones: the mouthpiece itself, the housing shell, and the internal components (supply packet, puncture device, spring). This segmentation allows the mouthpiece to undergo irreversible transition while other components remain fixed or perform their specialized functions, ensuring consistent operation without requiring the entire device to be rigid or inflexible.
