Solution Overview

Problem

Existing remote apparatus operation and sensing systems face challenges with high bandwidth requirements and latency issues, leading to inconsistent feedback and operator disorientation, particularly in situations where direct fiber optic links are impractical or unreliable.

Innovation Solution

The system employs prediction of future events to compensate for latency by generating virtualized views based on actual and predicted states of the apparatus and environment, reducing the need for real-time data transmission and allowing for de-coupled video between the apparatus and operator, thereby reducing bandwidth requirements and improving data compression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If video, audio, and other data are transmitted in real-time from the apparatus to the operator, then the operator receives current feedback, but the bandwidth requirement becomes excessively large and latency increases

Engineering Contradiction:

Improvefeedback consistencyVSAvoidbandwidth requirement

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system pre-processes and compresses video data on the apparatus side before transmission, performing necessary encoding and reduction operations in advance to minimize the bandwidth required for real-time transmission while maintaining feedback quality

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system extracts and transmits only the most critical feedback data elements in real-time, separating essential information from redundant data to reduce bandwidth requirements while preserving operational reliability

Inventive Principle:

Principle #2Taking out (Extraction)

2Quantity of substance

If data is compressed and processed through repeaters for wireless transmission, then the bandwidth requirement is reduced, but latency increases causing operator disorientation

Engineering Contradiction:

Improvebandwidth requirementVSAvoidlatency

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The system performs data compression and processing operations in advance on the apparatus side, completing all necessary data reduction before transmission begins to minimize the time data spends in transit and reduce overall latency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces a predictive rendering component that generates anticipated feedback based on current apparatus state and motion trends, acting as an intermediary that provides immediate visual feedback without waiting for actual transmitted data, thereby reducing perceived latency

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If the operator waits for the apparatus to become static before providing inputs, then operational accuracy improves, but productivity decreases due to cautious operation

Engineering Contradiction:

Improveoperational accuracyVSAvoidoperation speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The system implements predictive feedback that shows the operator where the apparatus will be based on current motion and control inputs, allowing the operator to see the future state of the apparatus and make adjustments proactively rather than reactively, maintaining accuracy while enabling continuous motion

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system transitions from static feedback (showing only current apparatus state) to dynamic predictive feedback that continuously updates based on apparatus motion and control inputs, enabling the operator to maintain accuracy during dynamic operation rather than requiring static conditions

Inventive Principle:

Principle #15Dynamics

4Speed

If fiber optic links are used to reduce latency, then transmission speed improves, but the system becomes vulnerable to fiber severing and is impractical in many situations

Engineering Contradiction:

Improvetransmission speedVSAvoiddeployment flexibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The system replaces the physical fiber optic connection with a wireless communication system, eliminating the mechanical vulnerability of fiber cables while maintaining transmission performance through advanced compression and predictive techniques

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
