Solution Overview

Problem

Conventional flat panel display apparatuses suffer damage from external impacts, such as dropping, due to the force exerted on the display panel when the bezel bends, leading to reduced operability.

Innovation Solution

A flat panel display apparatus design featuring a flat display panel with chamfered corners on a protruding substrate and an elastic bezel, which absorbs impact by allowing the bezel corners to bend while maintaining the display panel's integrity, and includes a flexible printed circuit board for improved attachment and electrical connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the bezel is made rigid to support the flat display panel, then structural stability is improved, but damage from external impact increases

Engineering Contradiction:
Improvestructural stabilityVSAvoiddamage from external impact
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The bezel material is changed from rigid to elastic, fundamentally altering the mechanical properties. This allows the bezel to deform elastically under impact forces, absorbing energy while maintaining structural integrity and protecting the flat display panel from damage.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The elastic bezel converts harmful impact forces into beneficial elastic deformation. When impact occurs, the bezel bends and absorbs the energy, then returns to its original shape, transforming the harmful impact into a protective mechanism that safeguards the display panel.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Ease of manufacture

If the first substrate extends beyond the second substrate to provide mounting surface, then ease of manufacture is improved, but vulnerability to impact increases

Engineering Contradiction:
Improvemounting convenienceVSAvoidimpact vulnerability
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The first substrate is designed with an asymmetric configuration, extending beyond the second substrate only at specific locations to create mounting surfaces. This asymmetric design provides manufacturing convenience for mounting while minimizing the exposed area, thereby reducing vulnerability to impact.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The first substrate has different properties in different regions: it extends beyond the second substrate only where mounting is needed, while remaining contained within the second substrate's boundaries in display areas. This local differentiation provides mounting convenience where needed while protecting vulnerable areas.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If the substrate corners are made sharp for precise alignment, then manufacturing precision is improved, but damage risk from impact increases

Engineering Contradiction:
Improvealignment precisionVSAvoidimpact damage risk
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The substrate corners are rounded instead of sharp, applying curvature to eliminate stress concentration points. This rounding maintains sufficient alignment precision for manufacturing while significantly reducing the risk of impact damage by distributing forces more evenly across the corner regions.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design significantly reduces damage to the flat display panel upon external impact, as the chamfered edges and elastic bezel absorb and distribute the force, minimizing the risk of damage and improving attachment stability.

Implementation Method 1

The bezel may include an elastic material. The elastic material may include metal. The chamfered corners of the protruding portion may be substantially planar.
