Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate driving units are used for dual emission in dual display apparatus, then dual emission functionality is achieved, but the overall thickness increases and manufacturing processes become complicated

Engineering Contradiction:
Improvedual emission functionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges two separate driving units into a single integrated driving unit that controls both the first light-emitting member (OLED) and the second light-emitting member (EL). This consolidation eliminates the need for separate driving circuits and control units, thereby reducing manufacturing complexity while maintaining dual emission functionality. The single driving unit coordinates both emission types through unified control architecture.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single driving unit is designed with multi-functionality to control both OLED and EL light-emitting members. It incorporates universal control circuits that can drive different emission types through standardized interfaces, enabling dual emission functionality without requiring separate specialized driving units for each emission type.

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

2Adaptability or versatility

If multiple separate driving units are used for dual emission in dual display apparatus, then dual emission functionality is achieved, but the overall thickness increases

Engineering Contradiction:
Improvedual emission functionalityVSAvoidoverall thickness
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent merges multiple driving units into a single integrated driving unit, eliminating redundant components and reducing the overall thickness of the display apparatus. The consolidated driving unit is positioned closer to the light-emitting members, reducing the distance required for signal transmission and structural support.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent repositions the driving unit to be located adjacent to the light-emitting members rather than behind them, utilizing horizontal space instead of vertical space. This dimensional rearrangement reduces the thickness direction length while maintaining all necessary driving functions for dual emission.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If a lens is commonly disposed over both areas to cover the light-emitting member, then dual emission is facilitated with simpler manufacturing, but light transmission control becomes more challenging

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidlight transmission control
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies local quality by creating different optical properties in different regions of the substrate. The first area (non-transmissive) and second area (transmissive) have distinct optical characteristics tailored to their specific functions. The lens is designed with region-specific optical properties to control light transmission appropriately for each emission type while maintaining manufacturing simplicity.

Inventive Principle:
Principle #3Local quality
