Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rigid and semi-rigid packaging for food and beverage products lacks effective protection against external aggressions and is not designed to be airtight, and there is a need for recyclable or biodegradable materials.
Innovation Solution
A casing design featuring a side panel part with a peripheral free edge and a sealing margin, sealed with a band to form a flange, providing an airtight bond using gluing, soldering, or welding, made from paper-based materials that are both mechanically strong and airtight, protecting against oxygen, moisture, and mechanical impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid and semi-rigid packaging is used to provide mechanical protection, then mechanical strength is improved, but airtightness and protection against external aggressions deteriorates
Solution Approach 1:
The packaging combines paperboard (mechanical strength) with aluminum foil or plastic film (airtightness) in a composite structure. The paperboard provides rigidity and protection against mechanical impacts, while the metallic or polymeric layer ensures hermetic sealing and barrier properties against oxygen and moisture.
Solution Approach 2:
A flexible sealing layer (aluminum foil or plastic film) is applied over the rigid paperboard structure. This thin film forms the airtight barrier while the underlying rigid structure provides mechanical support, resolving the contradiction between rigidity and sealing capability.
2Strength
If traditional packaging materials are used to ensure mechanical protection, then strength is improved, but recyclability and environmental compatibility deteriorates
Solution Approach 1:
The packaging is designed with separable layers that can be easily divided for recycling. The paperboard, aluminum foil, and plastic film layers can be separated through processes like delamination or manual sorting, allowing each material to be recycled through its appropriate stream.
Solution Approach 2:
The packaging structure facilitates recovery of valuable materials (aluminum and plastic) from the composite structure. The design enables efficient material recovery through recycling programs, transforming the waste stream into recoverable resources while maintaining protective functionality.
3Ease of manufacture
If paper-based materials are used to improve recyclability, then environmental compatibility is improved, but protection against moisture and oxidation deteriorates
Solution Approach 1:
Paper-based materials are combined with moisture and oxygen barrier layers (aluminum foil or plastic film). The paperboard provides recyclability and mechanical structure, while the metallic or polymeric layer provides the necessary barrier properties against moisture and oxidation.
Solution Approach 2:
An intermediary barrier layer (aluminum foil or plastic film) is introduced between the paperboard and the product. This intermediary layer protects the product from moisture and oxidation while allowing the paperboard to maintain its recyclable nature.
4Device complexity
If simple sealing methods are used to reduce complexity, then manufacturing simplicity is improved, but sealing reliability and airtightness deteriorates
Solution Approach 1:
The packaging structure incorporates self-sealing features through the interaction of its components. The flexible sealing layer conformally adheres to the rigid paperboard structure, creating automatic sealing through material properties rather than complex mechanical fastening systems.
Solution Approach 2:
The sealing function is merged into the structure itself through the conformal attachment of the flexible layer to the rigid layer. This integration eliminates the need for separate complex sealing mechanisms while ensuring reliable airtight sealing through the inherent properties of the composite structure.
