Solution Overview

Problem

Existing display apparatuses lack a flexible and easily variable rear cover structure that can adapt to shape changes of the display module, limiting their ability to provide enhanced sensory immersion and efficient power consumption.

Innovation Solution

A display apparatus with a rear cover comprising multiple divided sections defined by divided portions, allowing the rear cover to vary shape in conjunction with the display module, reducing the force required for shape change and minimizing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the rear cover is made as a single integrated piece, then structural stability is improved, but the force required for shape change increases and power consumption rises

Engineering Contradiction:
Improvestructural stabilityVSAvoidforce required for shape change
Core Design Contradiction:
Stability of the object's compositionVSForce

Solution Approach 1:

The rear cover is divided into multiple divided sections by divided portions, allowing each section to move independently during shape changes. This segmentation reduces the force required for deformation while the connection structures between sections maintain overall structural stability during operation.

Inventive Principle:
Principle #1Segmentation

2Force

If the rear cover is divided into multiple sections, then the force required for shape change is reduced, but structural stability may be compromised

Engineering Contradiction:
Improveforce required for shape changeVSAvoidstructural stability
Core Design Contradiction:
ForceVSStability of the object's composition

Solution Approach 1:

The divided sections are connected through nested connection structures where one section is partially inserted into or overlaps with adjacent sections. This nesting arrangement maintains structural integrity while allowing controlled movement between sections during shape changes.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The connection structures between divided sections are pre-configured with features such as protrusions and recesses that guide the movement path and maintain proper alignment during shape changes, ensuring structural stability is preserved throughout the transformation process.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If the rear cover is made rigid, then structural stability is improved, but adaptability to shape changes decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to shape changes
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The rear cover transitions from a static rigid structure to a dynamic structure where divided sections can move relative to each other. The connection structures enable controlled movement while maintaining stability, allowing the rear cover to adapt to various shapes corresponding to different display module configurations.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If the rear cover is made flexible with divided sections, then adaptability to shape changes is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to shape changesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rear cover is segmented into divided sections with connection structures between them. This segmentation enables adaptability to shape changes while keeping each individual section relatively simple in structure, balancing flexibility with manufacturing feasibility.

Inventive Principle:
Principle #1Segmentation
