Solution Overview

Problem

There is a strong demand for thinner electronic apparatuses, particularly the first chassis with a display, which affects the overall thickness and appearance quality, and existing designs struggle to achieve a balance between thinness and structural integrity while accommodating multiple displays.

Innovation Solution

The electronic apparatus features a first chassis with a glass plate covering the front display surface and another glass plate covering the rear display surface, supported by a frame that defines the lateral surfaces, using chemically strengthened glass and amorphous metal for structural support, allowing for a thinner design while maintaining durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the first chassis is made thinner to reduce overall device thickness, then the appearance quality and thinness are improved, but the structural integrity and durability are worsened

Engineering Contradiction:

Improvethickness of first chassisVSAvoidstructural integrity of first chassis

Core Design Contradiction:

Length of moving objectVSStrength

Solution Approach 1:

The first chassis employs a composite structure combining glass plates (for front and rear surfaces) with a metal frame (internal skeleton), creating a lightweight yet strong composite material system that achieves both thinness and structural integrity

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The first chassis is segmented into multiple functional layers including front glass plate, rear glass plate, and internal frame structure, allowing each component to be optimized independently for both thickness reduction and strength maintenance

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple displays are accommodated in the first chassis to increase versatility, then the adaptability is improved, but the device complexity and structural challenges are worsened

Engineering Contradiction:

Improvenumber of displaysVSAvoidstructural complexity of first chassis

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent utilizes the thickness dimension of the first chassis to accommodate multiple displays by arranging them at different depths and angles, transforming a 2D layout problem into a 3D spatial solution that reduces planar complexity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The glass plate structure serves multiple functions simultaneously: it acts as a protective cover, a structural support element, and a mounting surface for displays, reducing the need for separate components and simplifying the overall structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An electronic apparatus includes: a chassis; a first display in the chassis with a first display surface facing a front surface of the chassis; and a second display in the chassis with a second display surface facing a rear surface of the chassis. The chassis includes: a first glass plate that covers the first display surface and constitutes the front surface of the chassis; a second glass plate that covers the second display surface and constitutes the rear surface of the chassis; and a frame that supports the first glass plate and the second glass plate and constitutes lateral surfaces of the chassis.
