Solution Overview

Problem

Data drop rates during transmission from client devices to hosts in reality services (such as VR and AR) are high due to factors like bad transmission channels and occlusion, leading to unsatisfactory user interactions.

Innovation Solution

A method for managing data drop rate involves determining data components at specific time points and sending data packets with a fixed payload size, which includes both current and historical data components to ensure robust transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If data packets are transmitted over bad transmission channels in reality services, then transmission coverage and user mobility are improved, but data drop rate increases

Engineering Contradiction:

Improvetransmission coverageVSAvoiddata drop rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by proactively detecting data transmission quality in advance and adjusting packet composition accordingly. The system monitors transmission quality indicators and pre-adjusts the inclusion of historical data components in packets before transmission occurs, ensuring robustness against anticipated channel conditions without waiting for actual data loss to occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements parameter changes by dynamically modifying the composition of data packets based on transmission quality. When transmission quality deteriorates, the system changes the parameter of packet composition by including additional historical data components or adjusting the ratio of current to historical data, thereby adapting the transmission to maintain reliability under varying channel conditions.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If data packets include only current data components, then transmission efficiency is improved, but user interaction smoothness deteriorates when data is lost

Engineering Contradiction:

Improvetransmission efficiencyVSAvoiduser interaction smoothness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary action by preparing and including historical data components in advance within data packets. This allows the receiving end to have backup data readily available before transmission issues occur, ensuring smooth user interaction even when current data transmission is interrupted or lost, without requiring complex real-time retransmission protocols.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies beforehand cushioning by incorporating historical data components as a buffer or cushion against potential transmission failures. These historical data act as a safety margin that compensates for data loss, ensuring that user interaction remains smooth and uninterrupted even when current data transmission encounters problems on bad channels.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If data packets include both current and historical data components, then data transmission reliability is improved, but packet size and bandwidth consumption increase

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidpacket size

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies partial action by selectively including historical data components in packets based on transmission quality conditions rather than always including them. When transmission quality is good, only current data components are transmitted. When quality deteriorates, historical data components are added partially to the packet composition, thereby maintaining reliability while minimizing unnecessary bandwidth consumption during optimal transmission conditions.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system implements dynamics by making the packet composition flexible and adaptive rather than static. The ratio and inclusion of historical versus current data components dynamically adjust based on real-time transmission quality monitoring, allowing the system to optimize between reliability and packet size according to current channel conditions, thereby avoiding constant transmission of large packets regardless of need.
