Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for large household appliances are either time-consuming, environmentally harmful, or insufficiently secure and cushion heavy appliances, while current honeycomb panels require complex shaping and multiple handling steps, making them costly.
Innovation Solution
A processing tool for plate-shaped, layered pulp structures, comprising a base and tool plate with movable processing operators, allows simultaneous reshaping and cutting on both sides, using a spring base for easy insertion and forming packaging elements that securely package heavy appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If foamed components are used for packaging large household appliances, then cushioning and securing capability is improved, but packaging time increases and environmental friendliness deteriorates
Solution Approach 1:
The patent uses molded pulp packaging elements instead of reusable foam components. These pulp elements are designed to be disposable, biodegradable, and sufficiently strong for single-use packaging, eliminating the need for time-consuming foam curing while providing adequate cushioning protection.
2Strength
If honeycomb panels are used for packaging heavy household appliances, then structural support is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functions into a single molded pulp element that provides both structural support and cushioning in one integrated component. This eliminates the need for layering and joining multiple honeycomb panels, reducing device complexity while maintaining adequate support for heavy appliances.
Solution Approach 2:
The patent changes the material parameters by using molded pulp with optimized density and structural properties to achieve the required strength for heavy appliances without requiring complex multi-layer constructions.
3Strength
If complex shapes are created for packaging heavy appliances, then protection capability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces complex mechanical assembly of multiple panels with a single molding process. The molded pulp elements are formed directly into the required complex shapes using molding technology, simplifying manufacturing while maintaining the protection capability needed for heavy appliances.
