Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional packing materials for large, thin plate devices, such as LCD TVs, are inadequate in providing sufficient support and protection during transportation and storage, leading to increased damage and higher manufacturing costs due to compression and instability issues, and the need for eco-friendly alternatives is pressing as traditional materials like polystyrene foam and plastics are restricted.

Innovation Solution

A packing buffering device with a frame surrounding the plate device, utilizing hollow connecting rods and buffering pads made of degradable materials like paper tubes or pulp molds, which disperses stress and provides support to prevent damage and allows for increased stacking capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional buffering materials (polystyrene foam blocks and plastics) are used, then the plate device is protected from damage, but these materials are hard to degrade naturally and are restricted by environmental laws

Engineering Contradiction:

Improveprotection from damageVSAvoidenvironmental harm

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from non-degradable (polystyrene foam) to degradable (paper tube), resolving the environmental harm issue while maintaining protective function through structural design

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite structure combining paper tube material with specific geometric features (bent portions, positioning portions) to achieve both environmental friendliness and mechanical protection

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If buffering materials are reduced in amount to meet environmental requirements, then environmental impact is reduced, but the plate device cannot be supported properly and may be damaged

Engineering Contradiction:

Improveenvironmental impactVSAvoidsupport capability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The buffering device is segmented into multiple functional portions (first bent portion, second bent portion, positioning portions) that work together to provide comprehensive support with minimal material

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes three-dimensional spatial arrangement of the bent portions and positioning features to provide support in multiple directions, achieving adequate protection with reduced material quantity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If elastic and compressible materials (mold pulps, buffer blocks, bubble wraps) are applied around the devices for buffering, then some protection is provided, but the mechanical strength is insufficient and the packed product may be fell off easily because the gravity center is higher

Engineering Contradiction:

Improveprotection from damageVSAvoidmechanical strength

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent uses bent portions with curved geometries that provide structural strength and force distribution, replacing conventional compressible materials with inherently stronger curved paper tube structures

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The paper tube structure acts as a flexible yet strong shell that provides both protection and structural integrity, preventing the packed product from falling off while maintaining adequate mechanical strength

Inventive Principle:

Principle #30Flexible shells and thin films

4Reliability

If the plate device is packed with conventional buffering materials, then the device is protected, but the cost of packing materials relative to overall manufacturing cost is high

Engineering Contradiction:

Improveprotection from damageVSAvoidpacking cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent uses inexpensive paper tube material that can be easily manufactured and disposed of, replacing costly conventional buffering materials while maintaining protective function

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the material parameter to use cheaper, more abundant paper-based materials instead of expensive petroleum-based foams and plastics

Inventive Principle:

Principle #35Parameter changes

AI summary

A packing buffering device adapted to surrounding a plate device includes a first hollow connecting rod having a first body, a first connecting portion, and a first fixing portion and a second hollow connecting rod having a second body, a second connecting portion, and a second fixing portion. The first connecting portion and the first fixing portion are respectively extended and bent from two opposite ends of the first body and in contact with the frame of the plate device. The second connecting portion and the second fixing portion are respectively extended and bent from two opposite ends of the second body and in contact with the frame of the plate device. The first body and the second body are above the plate device and not in contact with the plate device. The distance between the fixing portions is less than the distance between the connection portions.
