Solution Overview

Problem

Existing display devices face challenges in storage and portability, durability, rigidity, heat dissipation, and shock absorption, particularly for portable designs.

Innovation Solution

A display device structure comprising a display module with a panel frame, side cover, and bumper, along with a hinge-connected top and bottom case, which includes a panel frame at the rear of the display panel, a side cover covering the side surface, and a bumper at the corner of the side cover, facilitating storage, improved rigidity, heat dissipation, and shock absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display device is designed to be portable, then storage and portability are improved, but durability and rigidity deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidrigidity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The display device is divided into multiple segments: a display module, a bottom case, and a top case. The display module can be detached from the bottom case and stored in the top case, allowing the device to be portable while maintaining structural integrity when assembled. This segmentation enables the device to transition between a compact portable state and a rigid assembled state.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display module is designed to be nested within the bottom case during use, and the entire display module can be stored within the top case when not in use. The top case and bottom case are hinge-connected, allowing the display module to be positioned between them. This nesting arrangement improves portability while the interlocking structure provides rigidity when assembled.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the display module is made detachable for storage, then storage convenience is improved, but structural stability deteriorates

Engineering Contradiction:
Improvestorage convenienceVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The top case and bottom case are pre-connected via a hinge connection, preparing the structure in advance for easy assembly and disassembly of the display module. This preliminary hinge connection allows the display module to be quickly inserted or removed without compromising structural stability when assembled, as the hinge maintains a fixed relationship between the top and bottom cases.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the device structure is simplified for portability, then portability is improved, but heat dissipation capability deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidheat dissipation
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The device is segmented into a bottom case containing heat-generating components and a top case with open or ventilated structures. This segmentation allows heat to be dissipated through the top case while maintaining a compact portable form. The separated structure provides thermal pathways without requiring complex heat dissipation mechanisms.

Inventive Principle:
Principle #1Segmentation
