Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing food delivery boxes, particularly those made of polystyrene foam, are not environmentally friendly due to low recyclability, leading to significant landfill waste and inefficiencies in maintaining food temperature and quality during delivery.
Innovation Solution
A foldable insulated box assembly comprising recyclable and repulpable materials, including insulator pads and a registration system, which maintains temperature and humidity levels using air flow and convection, allowing for the use of ice packs to keep food hot or cold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polystyrene foam boxes are used for food delivery, then low cost and temperature maintenance are achieved, but environmental friendliness and recyclability deteriorate
Solution Approach 1:
The patent changes the material parameter from non-recyclable polystyrene foam to recyclable paperboard with integrated insulation layers, maintaining manufacturing efficiency while improving environmental compatibility through material substitution
Solution Approach 2:
The patent employs composite material structure combining paperboard exterior with integrated insulation layers, creating a multi-layer composite that provides both thermal insulation performance and recyclability, resolving the contradiction between cost-effectiveness and environmental friendliness
2Temperature
If polystyrene foam boxes are used for food delivery, then temperature maintenance is achieved, but recyclability deteriorates
Solution Approach 1:
The patent uses composite material construction with paperboard layers and integrated insulation materials that work together to maintain thermal performance while enabling the entire box structure to be recyclable, eliminating the need to sacrifice recyclability for temperature control
3Stability of the object's composition
If traditional non-foldable box structures are used, then structural stability is achieved, but adaptability and space efficiency deteriorate
Solution Approach 1:
The patent transforms the static rigid box structure into a dynamic foldable design where panels can be collapsed and reconfigured, allowing the box to adapt between deployed (stable) and collapsed (space-efficient) states, simultaneously achieving structural stability during use and adaptability for storage and reuse
4Temperature
If insulated materials are added to maintain food temperature, then temperature control improves, but device complexity increases
Solution Approach 1:
The patent merges the insulation function directly into the box walls by integrating insulation layers within the panel structure itself, rather than adding separate insulation components, thereby achieving effective temperature control while minimizing structural complexity
