Modular Thermal Liner Assembly for Recyclable Insulated Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging for temperature-sensitive contents faces challenges such as spoilage, destabilization, freezing, melting, or evaporation due to temperature extremes during storage or shipping, and existing insulated packages are often bulky, specialized, and non-recyclable, leading to environmental issues and customer dissatisfaction.
Innovation Solution
A modular box assembly with pre-laminated thermal liners made from a mixture of reinforcement fibers and thermoplastic binder fibers, which are combined, heated, and cooled to create a fibrous web, then encapsulated between sheets to form insulated panels that can be easily assembled and reused, providing temperature control and recyclability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional insulated packages are used to maintain temperature extremes, then temperature control is achieved, but the packages become bulky and difficult to store
Solution Approach 1:
The insulation system is divided into separate modular panels that can be assembled only when needed. Each panel contains insulation material between facing sheets, and multiple panels are combined to create insulated boxes of various sizes, eliminating the need to store complete insulated packages when not in use.
Solution Approach 2:
The packaging system transitions from static pre-assembled insulated boxes to a dynamic modular system where insulation panels are assembled and disassembled based on demand. This allows the same set of panels to create different box configurations, reducing storage requirements for empty packages.
2Temperature
If specialized insulated packages are used for different temperature applications (hot, chilled, frozen), then temperature control is optimized, but the complexity of maintaining large stocks of specialized packaging increases
Solution Approach 1:
A single set of modular insulation panels with universal dimensions can be assembled to create packaging for hot, chilled, and frozen applications. The same panels serve multiple temperature purposes by combining different panels in various configurations, eliminating the need for separate specialized packaging stocks for each temperature type.
Solution Approach 2:
The insulation requirements for different temperature applications are met by varying the number and arrangement of modular panels rather than using fundamentally different packaging designs. By changing the quantity and configuration of standard panels, the system adapts to different thermal protection needs without requiring specialized package designs.
3Temperature
If traditional insulated packages are used, then temperature protection is provided, but the packages cannot be recycled and are disposed of in landfills
Solution Approach 1:
The modular panels are designed to be disassembled and recovered for recycling. The facing sheets and insulation material can be separated and processed through appropriate recycling streams, preventing the complete package from being discarded as non-recyclable waste in landfills.
Solution Approach 2:
The panels use composite construction with distinct layers (facing sheets and insulation material) that can be separated for recycling. This layered composite structure allows each material component to be recovered and processed appropriately, improving overall recyclability compared to integrated non-recyclable packaging.
4Volume of moving object
If modular panels are used to reduce storage space, then ease of storage is improved, but the assembly process becomes more complex
Solution Approach 1:
The packaging is segmented into standardized modular panels with uniform dimensions and attachment mechanisms. This segmentation allows panels to be easily stored in compact configurations and assembled through simple repetitive processes, reducing both storage space and assembly complexity compared to custom-built insulated boxes.

AI summary
A modular box assembly includes a box; a first thermal liner constructed of a first length of pre-laminated material, the pre-laminated material comprising an insulation batt in facing contact with a first sheet and with a second sheet, the first thermal liner defining three first liner panels; and a second thermal liner constructed of a second length of the pre-laminated material, the second thermal liner defining three second liner panels. A bottom box panel is covered by one of a first liner panel not covering any side box panel and a second liner panel not covering any side box panel. The insulation batt is formed from a mixture of reinforcement fibers and thermoplastic binder fibers, the reinforcement fibers comprising one of natural fibers, recycled cardboard, and a mixture of recycled cardboard and paper fibers.
