Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If function modules are integrated into the display device, then the functionality of the display device is enhanced, but the overall thickness of the display device increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidoverall thickness

Core Design Contradiction:

Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent applies reverse mounting of light emitting units on the back surface of the substrate, utilizing the z-dimension (depth/thickness direction) to redistribute components. This allows the function module to be positioned on the front surface while light emitting units are on the back surface, sharing the substrate thickness and reducing overall device thickness while maintaining enhanced functionality.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The function module and light emitting units share the same substrate, with the function module positioned on the front surface and light emitting units on the back surface. This nested arrangement allows both components to occupy the same spatial envelope, effectively reducing the overall thickness while integrating multiple functions into a compact structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If function modules are integrated into the display device, then more functions are achieved, but material costs increase

Engineering Contradiction:

ImprovefunctionalityVSAvoidmaterial costs

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges the function module and light emitting units onto a single substrate, with the function module on the front surface and light emitting units on the back surface. This consolidation eliminates the need for separate substrates and reduces the total quantity of materials required, thereby lowering material costs while achieving enhanced functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The substrate serves multiple functions by hosting both the function module on its front surface and light emitting units on its back surface. This multi-functional use of a single substrate reduces the total material quantity needed compared to using separate substrates for each component, thus reducing material costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)
