Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple components (display panel, optical sheet, frame, back cover) are separately assembled, then structural integrity is maintained, but device complexity and assembly time increase

Engineering Contradiction:
Improvenumber of componentsVSAvoidstructural integrity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines multiple separate components (display panel, optical sheet, frame, and back cover) into a single integrated front cover structure. This merging reduces the total number of components and simplifies the assembly process while maintaining the structural integrity through the unified design of the front cover that incorporates all these functional elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The front cover is designed as a multi-functional component that simultaneously serves as the display panel support, optical sheet mounting structure, frame integration, and back cover attachment point. This universal design allows a single component to perform multiple functions that previously required separate parts, thereby reducing device complexity.

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

2Productivity

If traditional multi-component assembly is used, then manufacturing precision is maintained, but assembly efficiency decreases

Engineering Contradiction:
Improveassembly efficiencyVSAvoidcomponent alignment
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

By merging the display panel, optical sheet, frame, and back cover into a single integrated front cover, the patent eliminates multiple alignment steps required in traditional assembly. The integrated structure ensures precise positioning of all components relative to each other by design, rather than requiring separate alignment operations during assembly.

Inventive Principle:
Principle #5Merging (Combining)

3Length of stationary object

If conventional structural design is used, then component functionality is preserved, but device thickness increases

Engineering Contradiction:
Improvedevice thicknessVSAvoidcomponent functionality
Core Design Contradiction:
Length of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent employs a nested structure where the display panel, optical sheet, and frame are integrated within the front cover volume. Components are arranged in a nested configuration that maximizes space utilization and minimizes the overall device thickness while preserving all necessary functional capabilities of each component.

Inventive Principle:
Principle #7Nested doll (Nesting)
