Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If plastic buffer materials are used, then protective effect against colliding stress is improved, but environmental harm increases

Engineering Contradiction:

Improveprotective effectVSAvoidenvironmental harm

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to paper-based materials, transforming the packing structure into an environmentally friendly alternative that maintains protective functionality while reducing environmental harm

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts the previously harmful plastic materials into beneficial recyclable paper materials, turning an environmental problem into a solution through material substitution

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-generated harmful factors

If paper packing structures are used, then environmental harm is reduced, but protective effect against colliding stress deteriorates

Engineering Contradiction:

Improveenvironmental harmVSAvoidprotective effect

Core Design Contradiction:

Object-generated harmful factorsVSStrength

Solution Approach 1:

The patent divides the packing structure into multiple functional components including buffer members, supporting boards, and buffer breaches, where each segment contributes to stress distribution and protection, enabling paper materials to achieve adequate protective effect

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a composite paper-based packing structure combining multiple components (buffer members with folded baseboards, supporting boards, buffer breaches) to achieve the necessary protective effect that single-material paper structures cannot provide

Inventive Principle:

Principle #40Composite materials

3Object-generated harmful factors

If paper packing structures with many pieces of cardboards are used, then environmental harm is reduced, but assembly complexity increases

Engineering Contradiction:

Improveenvironmental harmVSAvoidassembly complexity

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges multiple cardboard pieces into integrated components such as buffer members with folded baseboards and supporting boards that are pre-joined, reducing assembly complexity while maintaining the environmental benefits of paper materials

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A buffer device comprises a buffer member, a lateral side, a first supporting board and a second supporting board. In this case, the buffer member is formed with at least one folded baseboard. The lateral side is located at one side of the buffer member and has a first edge and a second edge. One side of the first supporting board is joined to the first edge and a first portion of the first supporting board covers at least one part of the lateral side. A second portion of the first supporting board is substantially perpendicular to the first portion and is folded to insert into the lateral side. One side of the second supporting board is joined to the second edge and a third portion of the second supporting board covers at least one part of the lateral side. A fourth portion of the first supporting board is substantially perpendicular to the third portion and is folded to insert into the lateral side.
