Solution Approach 1:

The patent applies dynamics by transitioning from static fiber optic cables to dynamic light-based communication where display devices can dynamically adjust bandwidth allocation and multiple spatiotemporal patterns can be transmitted simultaneously, enabling adaptive bandwidth management that responds to real-time data transmission needs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent replaces the mechanical connection system of physical cables and connectors with an optical field-based transmission system using light patterns displayed in free space, eliminating the need for physical network devices and enabling more flexible, high-bandwidth data transmission

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If routers and resource managers are used to manage internet traffic, then data routing is provided, but data corruption and throttling occur

Engineering Contradiction:

Improvetraffic management capabilityVSAvoiddata integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extracts the traffic management function from traditional routers and resource managers by implementing distributed intelligence where each node independently encodes and transmits its own data packets using light patterns, eliminating the need for centralized routing devices that cause bottlenecks and data corruption

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Each node in the network performs self-service by autonomously encoding data into spatiotemporal light patterns and transmitting them directly to destination nodes without requiring external routing management, thereby improving data integrity and eliminating throttling caused by centralized controllers

Inventive Principle:

Principle #25Self-service

3Speed

If traditional fiber connections are used, then data transmission occurs through cables, but network congestion and throttling reduce transmission speed

Engineering Contradiction:

Solution Approach 1:

The patent transitions from one-dimensional data transmission through cables to multi-dimensional transmission by encoding data in spatiotemporal light patterns that utilize spatial distribution, temporal sequencing, color variations, and intensity levels, dramatically increasing the dimensionality of information encoding and transmission capacity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs periodic action through synchronized display refresh cycles where multiple spatiotemporal patterns are transmitted in rapid succession, with each pattern representing data packets that can be independently decoded, enabling high-speed parallel data transmission

Inventive Principle:

Principle #19Periodic action
