Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality (VR) environments used for remotely controlling machines in manufacturing workflows, latency issues arise due to varying internet bandwidths of VR devices, leading to potential misexecution of commands and reduced productivity.
Innovation Solution
The method involves identifying machines involved in a manufacturing process and determining the workflow sequence. Based on conditions such as internet bandwidth of VR devices, the extent of the VR collaborative environment is tailored for each device to minimize latency. This is achieved by adjusting the clarity and content of the VR environment displayed on each device, ensuring that conditions do not introduce latency into the workflow sequence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the VR collaborative environment is displayed with high clarity and full content to all VR devices, then the visual quality and immersion are improved, but the internet bandwidth consumption increases causing latency in workflow sequence execution
Solution Approach 1:
The patent applies local quality by differentiating the VR environment display parameters for different VR devices based on their specific conditions. Each device receives a customized extent of the VR collaborative environment that matches its bandwidth capabilities, ensuring optimal visual quality without causing latency. This is achieved by assessing device conditions and tailoring the displayed content accordingly.
Solution Approach 2:
The patent changes the parameters of the VR environment display dynamically based on device conditions such as internet bandwidth. By adjusting the extent, clarity, and content of the VR collaborative environment displayed to each device, the system optimizes the balance between visual quality and latency, preventing bandwidth consumption from causing execution delays.
2Loss of information
If the extent of VR collaborative environment is increased for VR devices with low bandwidth, then the visual information completeness is improved, but the latency in command execution increases
Solution Approach 1:
The patent applies partial action by providing VR devices with low bandwidth a customized extent of the VR collaborative environment that contains essential information without overwhelming the device's processing and bandwidth capabilities. This partial display approach ensures that critical workflow information is conveyed while avoiding the latency that would result from transmitting complete high-fidelity environment data.
Solution Approach 2:
Different portions of the VR collaborative environment are displayed with different quality levels based on the specific needs and capabilities of each VR device. Devices with lower bandwidth receive a tailored view that prioritizes essential workflow information, while devices with higher bandwidth receive more complete visual information, optimizing the balance between information completeness and execution speed.
3Loss of time
If the VR environment is tailored to reduce bandwidth consumption, then the latency is reduced, but the visual quality and immersion experience deteriorates
Solution Approach 1:
The patent ensures that each VR device receives a customized extent of the VR collaborative environment that optimizes visual quality within its bandwidth constraints. Rather than uniformly reducing quality across all devices, the system tailors the display parameters locally for each device, maintaining immersion and visual fidelity where possible while adapting to bandwidth limitations.
Solution Approach 2:
The VR environment display parameters are dynamically adjusted based on real-time assessment of device conditions including internet bandwidth. This dynamic adaptation allows the system to optimize the balance between visual quality and latency for each device, ensuring that visual fidelity is maintained at the highest possible level without causing workflow execution delays.
4Device complexity
If all VR devices receive the same extent of VR collaborative environment, then the system complexity is reduced, but the latency varies significantly among devices with different bandwidths
Solution Approach 1:
The patent implements local quality by assessing the specific conditions of each VR device and tailoring the extent of the VR collaborative environment displayed to that device. This customization approach increases system complexity slightly but dramatically reduces latency variation among devices, as each device receives an optimized view matched to its bandwidth capabilities rather than a one-size-fits-all configuration.
Solution Approach 2:
The system dynamically adapts the VR environment display parameters for each device based on real-time condition assessment. This dynamic customization allows the system to accommodate devices with varying bandwidths without significant latency differences, with the complexity of condition assessment and parameter tailoring justified by the substantial improvement in workflow execution consistency.
