Paper Fiber Packaging With Variable Wall Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging for online shipping of liquid and gel products is inefficient in terms of space usage and generates excessive waste, as it often requires large transport packaging with fillers to prevent damage, which can lead to product spillage and increased costs.
Innovation Solution
A packaging system comprising an inner container and an outer container made of paper fibers, where the outer container has thicker walls in contact areas and cavities in spacing areas to securely hold the inner container, eliminating the need for additional fillers by forming an air cushion for shock absorption and allowing efficient volume adaptation to the product size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If larger transport packaging is used to prevent product damage, then product safety is improved, but packaging volume and waste increase
Solution Approach 1:
The inner container is nested within the outer container, with the outer container's wall extending into the receiving space to contact the inner container's wall, creating a fixed position without requiring additional filler materials. This nesting approach allows the packaging volume to be optimized to match the product volume while maintaining protection.
Solution Approach 2:
The outer container's wall is designed with varying thickness: thicker in contact areas to provide structural support and protection, and thinner in spacing areas to create hollow spaces that form air cushions for shock absorption. This beforehand cushioning design protects the product during transport without requiring excessive packaging volume.
2Stability of the object's composition
If filler materials are used to secure the product, then product stability is improved, but packaging waste increases
Solution Approach 1:
The invention extracts and eliminates the need for separate filler materials by integrating the cushioning and securing functions directly into the outer container's wall structure. The varying wall thickness creates contact areas for securing and hollow spaces for cushioning, removing the requirement for additional filler substances.
Solution Approach 2:
The outer container's wall is designed to perform multiple functions simultaneously: it provides structural support, secures the inner container through contact areas, and creates air cushions through hollow spaces for shock absorption. This merging of functions eliminates the need for separate filler materials and reduces packaging waste.
3Strength
If the outer container wall is made thicker throughout, then product protection is improved, but packaging volume increases
Solution Approach 1:
The outer container's wall is designed with non-uniform thickness: thicker in contact areas where the inner container's wall is located to provide maximum protection and secure the product, and thinner in spacing areas where hollow spaces are created for air cushioning. This local quality variation provides effective protection while minimizing overall packaging volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures safe and gentle shipping with reduced packaging volume and waste, while allowing easy consumer access to the product, as the inner container is fixed and cushioned within the outer container, preventing damage and spillage during transport.
Implementation Method 1
the hollow space formed in the spacing regions between the wall of the inner container and the wall of the outer container forms an air cushion, which cushions particularly sensitive areas of the inner container against vibrations and impacts
