Solution Overview

Problem

Due to the thinning of electronic devices, internal components are at risk of collision and damage from external impacts, leading to interference and malfunction.

Innovation Solution

A structure is implemented to prevent interference between components by using a support member and hinge structure to absorb external forces, protecting the flexible display panel and internal components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the electronic device is thinned to increase portable convenience, then the device becomes more compact and portable, but the mounting space for components decreases and components are at higher risk of collision from external impacts

Engineering Contradiction:
Improvethickness of electronic deviceVSAvoidrisk of component collision and damage
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

A support member is provided in the electronic device to prevent collision between a flexible display panel and other components. The support member acts as a cushioning structure that is positioned in advance to absorb and distribute external impacts, preventing direct contact between the flexible display panel and other internal components during drops or external forces.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Volume of moving object

If components are mounted in narrow space to achieve thinning, then device thickness is reduced, but components have short separation distance and may collide due to external impact

Engineering Contradiction:
Improvemounting space for componentsVSAvoidexternal impact causing component collision
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The support member serves as an intermediary structure between the flexible display panel and other internal components. It mediates the spatial relationship and physical interaction between components, providing a protective barrier that prevents harmful collisions while allowing the device to maintain its thin profile with components mounted in narrow space.

Inventive Principle:
Principle #24Intermediary (Mediator)
