Integrated Cushioning Packaging Structure for Filler-Free Goods Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carton packaging methods for express delivery are inefficient, costly, and environmentally unfriendly due to the use of filler materials like shredded paper and foam, which complicate the packaging process and lead to shifting and damage of goods during transportation.
Innovation Solution
A novel cushioning packaging structure comprising a base plate and an extendable cushioning pad, where both ends of the base plate are connected to the cushioning pad, forming an integrated structure that can be folded around the packaged item, with a sealing plate to enclose openings and support portions to enhance stability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filler materials such as shredded paper, bubble film, packing cotton, or foam are placed between inner walls of the cartons and a surface of the goods, then the goods can be cushioned and fixed, but the packaging process becomes complicated and packaging efficiency decreases
Solution Approach 1:
The base plate and cushioning pad are merged into an integrated structure where the cushioning pad is connected to the base plate, allowing the cushioning function to be incorporated into the packaging structure itself without requiring separate filler materials, thus simplifying the packaging process while maintaining protection
Solution Approach 2:
The invention extracts the cushioning function from separate filler materials and integrates it directly into the base plate structure through the connected cushioning pad, eliminating the need for additional filling steps and complex packaging procedures
2Reliability
If filler materials are used to cushion and fix the goods, then the goods are protected from damage, but packaging costs become difficult to control and increase
Solution Approach 1:
The integrated base plate with cushioning pad serves multiple functions simultaneously - providing structural support, cushioning protection, and goods fixation - eliminating the need for multiple separate components and reducing overall packaging costs while maintaining comprehensive protection
Solution Approach 2:
By combining the base plate and cushioning pad into one integrated structure, the invention reduces the total material cost and eliminates the need for purchasing and managing multiple separate filler materials, making packaging costs more controllable
3Reliability
If traditional filler materials are used for packaging, then goods can be protected, but environmental pollution increases due to non-degradable materials
Solution Approach 1:
The invention changes the material parameter of the cushioning pad from non-degradable traditional materials to biodegradable materials, maintaining the cushioning protection function while eliminating environmental pollution concerns
4Adaptability or versatility
If cartons are used with dimensions that do not perfectly match the shape of the goods, then the goods cannot be securely fixed, but this leads to goods shifting and colliding during transportation
Solution Approach 1:
The cushioning pad connected to the base plate provides dynamic adaptation to different goods shapes and sizes, allowing the packaging structure to conform to the goods being packaged while maintaining secure fixation and preventing shifting during transportation
