Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nicotine pouched products do not provide fast enough nicotine release for effective craving relief, and there is a desire for a discreet product that can be used without others noticing.
Innovation Solution
A nicotine pouched product with a saliva-permeable pouch containing a pouch composition comprising nicotine, water-insoluble fiber, and alkaline pH regulating agents, designed to release nicotine quickly and maintain a small, discreet size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pouch is heat sealed to close the opening, then the pouch is securely closed, but the heat sealing process damages the heat sealable layer and reduces its heat sealability
Solution Approach 1:
The pouch structure is divided into distinct functional layers: an inner layer with heat sealable properties for sealing, and an outer layer providing structural support and printability. This segmentation allows the heat sealable layer to be protected from damage during handling and storage, while still enabling effective heat sealing when needed. The inner layer can be a thin foil or coating that is preserved until the sealing operation.
Solution Approach 2:
The pouch is pre-assembled with the heat sealable layer in place and protected before the final sealing operation. The opening is prepared with the heat sealable material positioned and protected, allowing the pouch to be stored and transported in this pre-prepared state without degrading the heat sealability. The actual heat sealing is performed as a final step just before use.
2Weight of moving object
If the pouch material is made thin to reduce weight, then packaging efficiency improves, but the pouch becomes more susceptible to damage and contamination
Solution Approach 1:
The pouch employs a composite structure combining multiple materials with complementary properties. The inner layer provides heat sealability and can be made very thin (e.g., 6-12 micrometers), while the outer layer provides mechanical strength, tear resistance, and printability. This composite approach achieves weight reduction through the thin inner layer while maintaining overall pouch integrity through the supportive outer layer.
Solution Approach 2:
Different regions of the pouch have different material properties optimized for their specific functions. The inner layer has local heat sealable properties where needed, while the outer layer provides structural quality throughout. The heat sealable layer can be applied selectively to specific areas requiring sealing, while other areas use the outer layer for protection and information display.
3Loss of time
If the heat sealable layer is exposed to the environment during storage, then the pouch can be prepared in advance, but the heat sealability deteriorates over time
Solution Approach 1:
The pouch is pre-assembled with all components in place except for the final heat sealing operation. The heat sealable layer is positioned and protected during storage, allowing the pouch to be prepared in advance without exposing the heat sealable material to degrading environmental conditions. The actual sealing is performed as the final step just before use, ensuring maximum heat sealability.
Solution Approach 2:
A protective outer layer acts as an intermediary between the heat sealable inner layer and the external environment. This outer layer shields the heat sealable material from moisture, oxygen, and other environmental factors that would otherwise degrade its sealing properties during storage. The protective layer allows long-term storage while preserving the heat sealability for when it is finally needed.
