Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display device is made foldable with a hinge assembly, then portability and storage convenience are improved, but structural complexity and reliability concerns increase

Engineering Contradiction:

ImproveportabilityVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The display device is divided into separate modules including a display module, bottom case, top case, and hinge assembly. This segmentation allows each component to be optimized independently while maintaining overall portability through the foldable configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hinge assembly enables dynamic folding and unfolding of the display device, transitioning between flat and folded states. This dynamic capability improves portability while the hinge mechanism is designed with reinforcement structures to manage the associated structural complexity.

Inventive Principle:

Principle #15Dynamics

2Strength

If reinforcement structures are added to improve durability and rigidity, then structural strength is improved, but device weight and complexity increase

Engineering Contradiction:

ImprovedurabilityVSAvoiddevice weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

Reinforcement structures such as reinforcing ribs are added locally at critical areas including the hinge assembly and connection points between cases. This localized reinforcement improves durability and rigidity where needed without uniformly increasing the weight of the entire device.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device employs composite construction with cases and reinforcement structures made from materials optimized for both strength and weight. The hinge assembly and reinforcing ribs use materials and designs that provide necessary structural strength while minimizing additional weight.

Inventive Principle:

Principle #40Composite materials

3Temperature

If heat dissipation structures are added, then thermal management is improved, but device complexity and space requirements increase

Engineering Contradiction:

Improveheat dissipationVSAvoidstructural complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

Heat dissipation functions are merged with existing structural components. The cases and internal structures serve dual purposes as both structural elements and heat dissipation pathways, eliminating the need for separate dedicated heat dissipation components and reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If shock absorption structures are added, then protection against impact is improved, but device weight and volume increase

Engineering Contradiction:

Improveshock absorptionVSAvoiddevice volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

Shock absorption structures such as bumpers are pre-installed at critical impact zones including corners and edges of the display device. These structures provide proactive protection against impact and shock without requiring additional volume during normal operation, as they are integrated into the device housing.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
