Solution Overview

Problem

There is a need to improve the structure and design of display apparatuses to achieve a slim or thin form factor while maintaining functionality and rigidity, particularly for display modules using light-receiving type panels like LCDs, which require a more efficient and aesthetically appealing chassis design.

Innovation Solution

A method of manufacturing a chassis with a patterned surface that includes engraved patterns arranged in specific directions and intervals, allowing the chassis to be curved and supporting both the display panel and backlight unit, enabling a slim design while maintaining structural integrity and aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the chassis is made thinner to achieve a slim design, then the aesthetic appearance and compactness are improved, but the structural rigidity and strength are reduced

Engineering Contradiction:
Improvechassis thicknessVSAvoidchassis rigidity
Core Design Contradiction:
Length of moving objectVSStrength

Solution Approach 1:

The patent applies engraved patterns that create a porous or honeycomb-like structure on the chassis surface. This internal patterning provides structural reinforcement through geometric distribution of material, maintaining rigidity while keeping the overall chassis thickness reduced. The engraved patterns act as structural ribs that prevent deformation without requiring additional material layers.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The chassis combines a base material with engraved pattern structures to create a composite system. The patterned surface layer provides enhanced mechanical properties (rigidity and strength) while the underlying structure maintains thinness. This composite approach allows the chassis to exhibit both slim profile and structural integrity simultaneously.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If traditional flat chassis design is used, then manufacturing is simple, but aesthetic appeal and modern design requirements are not met

Engineering Contradiction:
Improvechassis manufacturing simplicityVSAvoidchassis aesthetic appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The engraved patterns are formed on the chassis surface during the manufacturing process itself, rather than as a separate post-processing step. This preliminary action integrates the aesthetic feature creation into the base manufacturing workflow, maintaining production efficiency while achieving the desired curved and patterned appearance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical curvature methods (such as bending or molding complex shapes) with a surface engraving technique. This substitution allows the chassis to maintain a simple flat base structure for easy manufacturing, while the engraved patterns optically and structurally create the appearance and effect of curvature and design complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Shape

If the chassis is made curved to improve aesthetic appeal, then the design modernity is enhanced, but the manufacturing complexity increases

Engineering Contradiction:
Improvechassis curvatureVSAvoidmanufacturing process complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical curvature formation processes with a surface engraving technique. Instead of physically bending or molding the entire chassis into a curved shape, the invention creates curved visual effects and structural reinforcement through engraved patterns on a relatively flat surface, significantly reducing manufacturing complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The curvature and patterning are applied locally to specific regions of the chassis surface through selective engraving, rather than requiring the entire chassis to be manufactured as a complex curved form. This localized approach allows standard manufacturing processes to produce the base chassis, with curvature effects added only where needed through the engraving process.

Inventive Principle:
Principle #3Local quality

4Shape

If engraved patterns are added to the chassis surface, then aesthetic appearance is improved, but manufacturing time and process complexity increase

Engineering Contradiction:
Improvesurface pattern appearanceVSAvoidchassis manufacturing efficiency
Core Design Contradiction:
ShapeVSProductivity

Solution Approach 1:

The engraved patterns are created as part of the base manufacturing process rather than as a separate finishing step. This preliminary action ensures that the patterning tooling is integrated into the main production line, allowing patterns to be formed during the same operational cycle that produces the chassis itself, thereby minimizing additional manufacturing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The engraving process serves multiple functions simultaneously: it creates the aesthetic pattern design, provides structural reinforcement to the chassis, and defines the curved visual effects. This multi-functionality means that a single manufacturing step achieves three different objectives, preventing the need for separate processes for each function and thus maintaining productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
