Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display carriers fail to provide adequate protection against external factors such as sunlight, dust, and impact during carrying, and may cause damage to the display due to movement within storage cases.

Innovation Solution

A display carrier with a storage box and a window part that can be closed using a closing member, featuring a fixing member to secure the display and prevent movement, and a supporting member for the closing member that also serves as a leg, ensuring the display is sealed and protected while allowing visual recognition and easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a display cover is used to protect the display, then impact protection is improved, but dust and sunlight protection deteriorates

Engineering Contradiction:

Improveimpact protectionVSAvoiddust and sunlight protection

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The protective structure is divided into two parts: a display cover for impact protection and a storage case for complete protection against dust and sunlight. The display cover can be detached and stored inside the storage case when full protection is needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The display cover is designed to fit inside the storage case, creating a nested structure. When the display cover is not in use, it can be placed inside the storage case to maintain a compact form and provide complete protection.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If a storage case is used to store the whole display, then protection from external factors is improved, but display stability deteriorates

Engineering Contradiction:

Improveprotection from external factorsVSAvoiddisplay stability

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

Fixing members are pre-installed inside the storage case at positions designed to securely hold the display. These fixing members are prepared in advance to prevent display movement when the display is placed inside the storage case.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Fixing members act as intermediaries between the display and the storage case. These members provide a secure interface that prevents direct contact and potential damage between the display and the storage case walls while maintaining stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a display cover is used with only display part exposed, then operability is improved, but complete protection deteriorates

Engineering Contradiction:

ImproveoperabilityVSAvoidcomplete protection

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The display cover is designed to be dynamically removable and reposable. During use, the cover can be removed or opened to provide full access to the display for operation. When protection is needed, the cover can be closed or placed inside the storage case.

Inventive Principle:

Principle #15Dynamics

AI summary

A display carrier has: a storage box which stores a display; a fixing member which fixes the display in the inside of the storage box; a window part which is formed on a face which is opposite to a screen of the display when the display is fixed in the inside of the storage box among a plurality of faces of the storing box; and a closing member which closes the window part.
