Solution Overview

Problem

Existing cushioning liners for electronic products have low structural strength and fail to withstand lateral external forces, leading to inadequate protection during transportation.

Innovation Solution

A packaging structure comprising two sets of support plates, each set including perpendicular internal and external support plates, which are assembled with precise alignment to form frames that enhance structural strength and protect against lateral forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple frame structure enclosed by four support plates is used, then the manufacturing complexity is reduced, but the structural strength and ability to withstand lateral external forces deteriorates

Engineering Contradiction:

Improvestructural complexityVSAvoidstructural strength

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The support plates are divided into external and internal components that fit together. Each support plate consists of an external support plate and an internal support plate, creating a segmented structure that enhances strength while maintaining manageable complexity through modular assembly

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The internal support plates are nested within the external support plates. The internal support plates fit inside the external ones, creating a nested configuration that increases structural strength and lateral force resistance without significantly increasing overall complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If internal and external support plates are used with precise fitting, then the structural strength is improved, but the manufacturing precision requirement increases

Engineering Contradiction:

Improvestructural strengthVSAvoidalignment accuracy

Core Design Contradiction:

StrengthVSManufacturing precision

Solution Approach 1:

The internal support plates are designed to automatically align and fit within the external support plates during assembly. The fitting structure enables self-alignment, reducing the need for high-precision manual positioning while maintaining strong structural connections

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The internal and external support plates have asymmetric fitting interfaces with specific geometric features. This asymmetry creates a unique fit that guides proper alignment during assembly, ensuring accurate positioning without requiring excessive manufacturing precision

Inventive Principle:

Principle #4Asymmetry

AI summary

A packaging structure includes two first support plates and two second support plates. The two first support plates are parallel to each other and arranged at intervals. Each of the first support plates includes a first external support plate and a first internal support plate that fit against each other. The two second support plates are parallel to each other, arranged at intervals, and located between the two first support plates. Each of the second support plates includes a second external support plate and a second internal support plate that fit against each other. Two ends of a second external support plate abut against the plate surfaces of two first external support plates respectively. Two ends of a second internal support plate abut against the plate surfaces of two first internal support plates respectively.
