Paper Spring Packaging for Impact Absorption and Recyclability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shipping packaging systems are not environmentally friendly, require separate boxes or cushions for different-sized products, and lack recyclability, which complicates the supply chain and increases environmental impact.
Innovation Solution
The integration of paper springs made from recyclable materials into shipping boxes provides cushioning and protection by compressing to absorb impact forces, allowing for flexible accommodation of various product sizes and enabling recyclability without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polymeric film retention systems or expanded polystyrene cushions are used, then product protection and retention are improved, but environmental friendliness and recyclability deteriorate
Solution Approach 1:
The patent changes the material parameter from non-recyclable polymeric film and expanded polystyrene to recyclable paper-based materials. The paper springs maintain the necessary mechanical properties for product protection while being environmentally friendly and recyclable, thus resolving the contradiction between product protection and environmental impact.
Solution Approach 2:
The patent uses homogeneous paper-based material for both the box structure and the retention/cushioning springs. This eliminates the need for mixed materials (polymer film, polystyrene, cardboard) that are difficult to recycle together, improving recyclability while maintaining protective functions.
2Reliability
If separately sized boxes or separately designed cushions are used for different sized products, then product protection is improved, but device complexity and supply chain flexibility deteriorate
Solution Approach 1:
The patent introduces dynamic, flexible paper springs that can adapt their configuration based on the product size. The springs can be compressed to different degrees and arranged in various configurations within the same box, allowing a single packaging design to protect products of varying sizes without requiring multiple specialized packaging solutions.
Solution Approach 2:
The paper springs serve multiple functions: they act as retention mechanisms to hold products in place, provide cushioning protection, and allow for size adaptation. This multi-functionality eliminates the need for separate retention systems and cushioning materials, simplifying the overall packaging system while maintaining product protection across different product sizes.
3Force
If traditional cushioning systems are used, then impact absorption is improved, but recyclability and ease of disposal deteriorate
Solution Approach 1:
The patent changes the material composition from non-recyclable expanded polystyrene to recyclable paper-based material. The paper springs maintain impact absorption capabilities through their spring mechanism and material properties while being fully recyclable with the cardboard box, thus resolving the contradiction between impact absorption and recyclability.
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 solution enhances packaging integrity and recyclability while reducing environmental impact by using eco-friendly materials that absorb impact energy and accommodate different product sizes, simplifying the supply chain and improving product protection during transport.
Implementation Method 1
In response to an impact force, the first (or second) paper spring compresses and resiliently absorbs and damps the force and slows the acceleration of the product.
Implementation Method 2
the first (or second) paper spring compresses and resiliently absorbs and damps the force

AI summary
Packaging may include a base box having a cavity to receive a product, and a first paper spring extending from an interior of a first sidewall of the base box and a second paper spring extending from an opposing interior of a second sidewall of the base box. Each of the first and second paper springs may be formed from the same blank as the first sidewall. The first and second springs are flexible such that the cavity may accommodate products of different lengths, and may resiliently absorb vibrations or impact forces during shipping.
