Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the display size is increased to improve viewing capacity, then the viewing capacity is improved, but the portability deteriorates

Engineering Contradiction:
Improvedisplay areaVSAvoidportability
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The display device transitions from a static rigid structure to a dynamic foldable structure that can change its form factor. The display is divided into multiple segments that can be folded relative to each other, allowing the device to transition between expanded and compact states, thus resolving the contradiction between large display area and portability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The foldable display segments are nested within each other when folded, similar to nested dolls. The second display segment can be folded over or under the first segment, allowing the larger display area to be compacted into a smaller portable form factor without losing the total display area.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Area of stationary object

If the display size is increased to improve viewing capacity, then the viewing capacity is improved, but the precision of physical interaction deteriorates

Engineering Contradiction:
Improvedisplay areaVSAvoidphysical interaction precision
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The hinge mechanism acts as an intermediary between the user's physical interaction and the virtual object control. By detecting the hinge's rotational position and motion, the system can precisely control virtual objects in the larger display environment, bridging the gap between physical interaction scale and virtual object scale.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct mechanical interaction with the display surface (fingers touching the screen) with a mechanical sensing system at the hinge. The hinge's rotational mechanics are detected by sensors and translated into precise virtual object control, substituting the direct touch interface with a mechanical sensing interface that maintains precision across larger display areas.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Strength

If a rigid display structure is used to maintain structural integrity, then the structural integrity is improved, but the adaptability deteriorates

Engineering Contradiction:
Improvestructural integrityVSAvoidform factor adaptability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The display is segmented into multiple rigid sections that maintain their individual structural integrity. These segments are connected through a hinge mechanism, allowing the overall structure to adapt its form factor while each segment maintains its rigidity and strength, thus resolving the contradiction between structural integrity and form factor adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The structure transitions from completely rigid to dynamically adaptable. The hinge mechanism introduces controlled flexibility between rigid display segments, allowing the device to change its form factor (folded/unfolded states) while maintaining structural integrity of individual segments and the overall assembly.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If standard touch screen interface is used to maintain simplicity, then the interface simplicity is improved, but the functionality for motion-controlled applications deteriorates

Engineering Contradiction:
Improveinterface complexityVSAvoidmotion control functionality
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The hinge mechanism serves multiple functions: it enables form factor transformation, provides motion sensing for virtual object control, and acts as a physical interface for interaction. This multi-functionality allows the system to maintain relative simplicity while enabling advanced motion-controlled applications that would require complex separate hardware.

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

AI summary

A foldable touch screen display device made up of flexible or tiled display segments that can be folded from a compact state to an expanded state which also includes a gaming motion control interface. The form factor of the compact state is roughly the size of a typical handheld phone or smaller. The form factor of the expanded state is roughly the size of a larger phone or tablet computer, which may also have the mechanical functionality of a laptop. The gaming motion control interface can provide enhanced interaction and viewing of a game application by utilizing the inherent folding mechanics and position of each display segment relative to each other such that a virtual object or point of reference shown on the display corresponds with the device's folding motion. Other applications that do not relate to gaming may also be applied utilizing the same techniques disclosed.
