Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a separate fixing device is used to maintain the enlarged or downsized state of the display area, then the display area can be maintained, but the whole size and weight of the flexible display apparatus increases

Engineering Contradiction:

Improvedisplay area maintenanceVSAvoidapparatus weight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent replaces mechanical fixing devices with a magnetic field system to maintain the display area in enlarged or downsized states. Magnets are embedded in the housing and interact with magnetic portions on the display panel to provide holding force without mechanical contact, eliminating the need for separate fixing devices and reducing overall apparatus weight.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic field as an intermediary between the housing and the display panel to achieve the fixing function. The magnetic field acts as a mediator that transmits the holding force without requiring direct mechanical connection or separate fixing components, thereby maintaining display area stability while minimizing weight increase.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a separate fixing device is used to maintain the enlarged or downsized state of the display area, then the display area can be maintained, but the whole size of the flexible display apparatus increases

Engineering Contradiction:

Improvedisplay area maintenanceVSAvoidapparatus size

Core Design Contradiction:

Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent replaces mechanical fixing devices with a magnetic field system to maintain the display area in enlarged or downsized states. Magnets are embedded in the housing and interact with magnetic portions on the display panel to provide holding force without mechanical contact, eliminating the need for separate fixing devices and reducing overall apparatus weight.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic portion integrated into the housing serves multiple functions: it provides the holding force to maintain the display area in various states and simultaneously acts as part of the structural housing. This multi-functionality eliminates the need for separate fixing devices and reduces overall apparatus size.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Extent of automation

If driving power is added to automatically enlarge and downsize the display area, then the display area adjustment is automated, but the whole size and weight of the flexible display apparatus increases

Engineering Contradiction:

Improvedisplay area adjustmentVSAvoidapparatus weight

Core Design Contradiction:

Extent of automationVSWeight of moving object

Solution Approach 1:

The patent employs magnetic attraction and repulsion forces that automatically respond to user hand gestures without requiring external driving power. The magnetic portions interact with the magnets in the housing to self-adjust the display area based on the user's input, eliminating the need for motors or power-consuming actuators while maintaining automation functionality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces motor-driven mechanical adjustment systems with a magnetic field-based system. The magnetic forces provide the driving force for display area adjustment without requiring electrical power or mechanical actuators, thereby reducing apparatus weight while maintaining automated adjustment capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
