Corrugated Insulated Panels With Recyclable Flute Fill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature-controlled packaging solutions for shipping often utilize non-recyclable insulating materials, such as polystyrene foam, which are not properly recycled due to integration with other materials or secure adhesion, leading to improper segregation and waste accumulation.
Innovation Solution
An insulated panel comprising a corrugated medium with flutes filled with a recyclable insulation material, such as starch-based or cellulose fiber, allowing for easy recycling and integration with paper streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-recyclable insulating materials like polystyrene foam are used, then temperature control is maintained, but recyclability deteriorates
Solution Approach 1:
The patent changes the material parameter from non-recyclable polystyrene foam to recyclable materials such as paperboard, cardboard, or molded fiber. These alternative materials maintain the necessary insulating properties for temperature control while being fully compatible with existing recycling infrastructure, thus resolving the contradiction between temperature control reliability and recyclability
Solution Approach 2:
The patent employs composite construction by combining insulating material layers with recyclable structural components. The insulation is integrated with paperboard or cardboard layers that form the panel structure, creating a composite material system that achieves both effective temperature control and full recyclability through existing paper recycling streams
2Stability of the object's composition
If insulating materials are integrated with other materials or securely attached, then structural stability is improved, but ease of segregation for recycling deteriorates
Solution Approach 1:
The patent applies segmentation by designing the insulated panel as distinct, separable layers including insulating material and recyclable structural components. The insulation is positioned within flutes or cavities of the paperboard structure, allowing the materials to remain functionally integrated during use but easily separable for recycling by simply separating the layers without complex disassembly
Solution Approach 2:
The patent uses an intermediary approach where the insulating material is held in place by the physical structure of the paperboard flutes rather than strong adhesives. This allows the insulation to remain stable during shipping while enabling easy separation for recycling by simply pulling the layers apart, eliminating the need for chemical adhesive bonds that would complicate segregation
