Solution Overview

Problem

Mobile terminals with flexible displays are vulnerable to damage due to their exposed and curved nature, affecting durability and posing a risk to the display unit.

Innovation Solution

A mobile terminal design featuring a side frame with a dust-proof pad and a structure that includes an inner and outer decor, fastening portions, and a spring washer to protect the flexible display unit, while allowing for adjustable screen size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a flexible display unit is used to enable variable screen size, then adaptability is improved, but the display unit becomes vulnerable to damage from foreign substances and physical impact

Engineering Contradiction:

Improvevariable screen sizeVSAvoiddurability of display unit

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The side frame is divided into multiple components: inner decor, outer decor, and dust-proof pad. This segmentation allows each component to perform its specific function - the inner decor provides structural support, the outer decor provides aesthetic coverage, and the dust-proof pad specifically protects against foreign substances entering the display unit

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dust-proof pad acts as an intermediary element positioned between the display unit and the external environment. It specifically blocks foreign substances from reaching the display unit while allowing the flexible display to maintain its variable size capability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the display unit is curved and exposed to the outside for flexibility, then adaptability is improved, but the display unit becomes vulnerable to physical damage

Engineering Contradiction:

Improveflexibility of displayVSAvoidphysical damage risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The side frame structure, particularly the inner decor and outer decor layers, provides beforehand protection against physical impact. These layers are positioned to cushion and absorb external forces before they can reach the flexible display unit, preventing damage while allowing the display to maintain its curved, flexible state

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A mobile terminal that can be switched from a first state to a second state by expanding in a first direction comprises: a body that can expand in the first direction; a display unit including a front part positioned on the front surface of the body, a rear part positioned on the rear surface of the body, and a side part which is positioned between the front part and the rear part and which encompasses the side surface of the body in the first direction; and a side frame which covers the side part of the display unit and which is coupled to the body, wherein, with respect to the side frame, the mobile terminal including a dustproof pad for removing foreign substances includes the side frame for covering the side part of the flexible display unit, and thus can prevent the display unit from being damaged.
