Elastic Sheet Packaging Apparatus for Fragile Product Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging structures fail to provide adequate protection and cushioning for fragile or high-value products during transportation and testing, leading to potential damage and performance issues.
Innovation Solution
A packaging apparatus comprising a main body with a base plate and side plates, an elastic sheet connected to the side plates, and optional corner plates and folding plates, which provides enhanced cushioning and protection by distributing impact forces and immobilizing the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple packaging structure with elastic film and paper card is used, then the packaging is cost-effective and easy to manufacture, but the cushioning and protection performance is insufficient for fragile products
Solution Approach 1:
The packaging structure is divided into multiple functional components: base plate for product support, side plates for lateral constraint, corner plates for impact absorption at vulnerable points, and elastic sheet for overall compression. Each segment performs a specific protection function, transforming a simple single-layer structure into a multi-component system that provides comprehensive protection while maintaining manufacturing simplicity.
Solution Approach 2:
The packaging combines different materials with complementary properties: rigid plates (paper card or corrugated board) provide structural support and impact resistance, while the elastic film provides cushioning through deformation. This composite approach integrates the advantages of rigid and flexible materials to achieve both protection performance and cost-effectiveness.
2Reliability
If additional protective components are added to improve cushioning performance, then the protection capability is enhanced, but the device complexity increases
Solution Approach 1:
Multiple protective functions are merged into a single integrated packaging apparatus. The base plate, side plates, corner plates, and elastic sheet work together as a unified system where the elastic sheet connects all rigid components, providing both structural integrity and cushioning in one assembled unit rather than separate protective elements.
Solution Approach 2:
The packaging apparatus is designed to perform multiple protection functions simultaneously: the base plate provides bottom support and compression resistance, side plates provide lateral constraint, corner plates protect against impact at vulnerable points, and the elastic sheet provides overall cushioning and product immobilization. This multi-functionality achieves comprehensive protection without requiring multiple separate packaging components.
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
The packaging apparatus significantly improves the cushioning and protection performance, reducing the risk of product damage during transportation and testing, while maintaining a cost-effective and simple structure.
Implementation Method 1
A package structure including an elastic film and a paper card is widely used for product package. Specifically, using the package structure, a product may be placed on the paper card, the elastic film may cover the product and connected with the paper card. The product is packaged by pressing the product on the paper card based on the elasticity of the elastic film.
