Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display device is designed to be portable with movable components, then storage and portability are improved, but durability and rigidity deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidrigidity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The display device employs a hinge mechanism that enables dynamic movement between the display module and bottom case, allowing the device to transition between different operational states (open/closed, folded/unfolded) while maintaining structural integrity through controlled articulation points

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is divided into distinct modular segments including the display module, bottom case, and hinge connection, allowing each component to be optimized independently for portability while the overall segmented structure maintains durability through distributed stress points

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the display device is made compact for portability, then storage is improved, but heat dissipation capability deteriorates

Engineering Contradiction:
ImprovecompactnessVSAvoidheat dissipation
Core Design Contradiction:
Volume of moving objectVSTemperature

Solution Approach 1:

The frame structure incorporates specific regions with enhanced thermal conductivity properties and strategically positioned heat dissipation features at critical heat-generating locations, while maintaining compact overall dimensions through localized rather than uniform design approaches

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The frame includes vertically extending structures and multi-layered configurations that increase heat dissipation surface area in the vertical dimension without significantly increasing the horizontal footprint, enabling effective thermal management within a compact form factor

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

3Ease of manufacture

If the display device uses a simple structure for ease of manufacture, then manufacturing cost is reduced, but shock absorption capability deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidshock resistance
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The frame incorporates pre-designed shock absorption features including flexible sections and energy-dissipating structures that are integrated into the basic frame geometry, providing impact protection through the inherent mechanical properties of the frame structure itself without requiring separate complex cushioning systems

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The frame utilizes composite construction combining materials with different mechanical properties, such as rigid sections for structural support and more ductile sections for shock absorption, creating a multi-functional structure that provides both manufacturing simplicity and enhanced durability

Inventive Principle:
Principle #40Composite materials
