Paper-Based Appliance Packaging Base Plate With Separable Recess Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance packaging made from expanded polystyrene is stiff, bulky, and environmentally unfriendly due to low recyclability and microplastic content, with recesses only accommodating downward protrusions and being rigidly fixed at the top.
Innovation Solution
A paper-based household appliance packaging system with a base plate featuring a cover layer and an additional layer, including a recess for a centering receptacle, a predetermined separation point, and a cover layer that can be easily severed to accommodate a base part, ensuring precise positioning and stable installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If expanded polystyrene is used for packaging, then the packaging is stiff and bulky, but it is environmentally unfriendly and not recyclable
Solution Approach 1:
The patent changes the material parameter from expanded polystyrene to paper-based materials, fundamentally altering both the environmental properties and the structural characteristics of the packaging base plate
Solution Approach 2:
The patent employs composite construction by combining multiple paper-based layers (cover layer, additional layer, and base plate) to achieve the necessary mechanical strength while maintaining environmental benefits
2Stability of the object's composition
If the recess is rigidly fixed at the top, then the structure is stable, but the recess cannot be accessed or modified during installation
Solution Approach 1:
The patent divides the cover layer into separable sections through predetermined separation points, allowing the cover layer to be opened or modified during installation while maintaining the integrity of the recess structure
Solution Approach 2:
The patent pre-forms the recess in the additional layer during manufacturing, so that the recess is ready for appliance placement without requiring on-site modification or access during installation
3Reliability
If the cover layer is made intact, then the recess is protected from deformation, but the base part of the appliance cannot be easily positioned
Solution Approach 1:
The patent incorporates predetermined separation points in the cover layer that allow controlled opening or lifting of the cover layer during appliance positioning, while maintaining recess integrity when closed
Solution Approach 2:
The additional layer acts as an intermediary structure that contains the recess and provides a stable interface between the cover layer and the appliance base part, allowing easy positioning without compromising recess integrity
