Solution Overview

Problem

Honeycomb structured bodies are prone to breakage and frictional damage during packaging and transportation due to vibration, as the peripheral coat layer is susceptible to chipping and cracking, despite existing packing solutions that attempt to mitigate these issues.

Innovation Solution

A packing member for honeycomb structured bodies featuring a holding member with recessed portions and a covering member that forms a gas layer between the covering member and the corner portions, providing a cushioning effect to absorb impacts and maintain a secured state even under continuous vibration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a holding member with recessed portion is used to hold the honeycomb structured body, then the honeycomb structured body can be securely held, but the corner portion of the recessed portion causes frictional damage to the peripheral coat layer

Engineering Contradiction:

Improveholding securityVSAvoidfrictional damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A covering member is introduced as an intermediary between the holding member's corner portion and the honeycomb structured body. The covering member has a curved surface that contacts the honeycomb structured body, eliminating the sharp corner portion that causes frictional damage while maintaining secure holding through the curved contact surface.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of modifying the holding member's corner portion to eliminate the harmful sharp edge, the invention inverts the approach by covering it with a separate member that has the desired curved geometry. This transforms the harmful sharp corner into a beneficial curved contact surface.

Inventive Principle:

Principle #13The other way round (Inversion)

2Strength

If cushion members are placed between the holding member and box, then impact protection is provided, but frictional damage from the recessed portion corner remains

Engineering Contradiction:

Improveimpact resistanceVSAvoidfrictional damage

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The protection system is segmented into two distinct functions: cushion members handle impact protection from external forces, while the covering member specifically addresses frictional damage from the recessed portion corner. This division allows each component to optimize its specific protective function without compromising the other.

Inventive Principle:

Principle #1Segmentation

3Stability of the object's composition

If resin sheet or paper cloth is inserted between recessed portion and honeycomb structured body, then close contact is achieved, but frictional damage increases

Engineering Contradiction:

Improvecontact stabilityVSAvoidfrictional damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The covering member is designed as a thin film structure with a curved surface that provides stable contact with the honeycomb structured body. Unlike flat resin sheets or paper cloths that create friction, the curved flexible surface of the covering member conforms to the body shape and reduces frictional damage while maintaining contact stability.

Inventive Principle:

Principle #30Flexible shells and thin films

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 solution effectively prevents breakage and frictional damage by absorbing impacts and maintaining a secured state, reducing stress on the honeycomb structured bodies and preventing ceramic powder adhesion, thus enhancing the durability and recyclability of the packing system.
