Solution Overview

Problem

The large volume of operating state data from sensors on working vehicles causes communication delays and interruptions when transmitted wirelessly, making real-time remote monitoring of the vehicle's state difficult due to the need for short sampling cycles and multiple sensors.

Innovation Solution

A remote diagnosis system that generates client screen data based on operating state data and transmits this data via a wireless communication device, allowing for real-time display on a client apparatus without the need for raw data transmission, thereby reducing data volume and minimizing communication delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If operating state data from multiple sensors is transmitted with short sampling cycles, then real-time monitoring capability is improved, but communication delay and interruption occur due to large data volume

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidcommunication reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent segments the raw operating state data into two categories: essential data for real-time monitoring and detailed data for analysis. Only essential data is transmitted at short sampling cycles to maintain real-time capability, while detailed data is transmitted less frequently or processed locally, thus reducing communication load and preventing delays/interruptions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and transmits only the essential real-time parameters (such as critical sensor readings) while leaving detailed data processing to be performed locally or asynchronously. This extraction approach reduces the data volume transmitted over the wireless communication channel, maintaining real-time monitoring without overwhelming the communication system.

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If a number of sensors are attached to the working vehicle, then measurement precision and monitoring coverage are improved, but data volume increases causing communication delays

Engineering Contradiction:
Improvemonitoring coverageVSAvoidcommunication delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies local quality by processing and filtering sensor data locally on the working vehicle before transmission. Each sensor's data is evaluated locally to determine if it contains essential real-time information, and only such data is transmitted. This local processing maintains comprehensive monitoring coverage while reducing the overall data volume sent remotely, preventing communication delays.

Inventive Principle:
Principle #3Local quality

3Speed

If data is transmitted with short sampling cycles, then real-time property is maintained, but communication bandwidth is exceeded causing interruption

Engineering Contradiction:
Improvesampling rateVSAvoidcommunication efficiency
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The patent performs preliminary action by pre-processing sensor data on the working vehicle to identify and extract only essential real-time parameters before transmission. This preliminary filtering and selection reduces the data volume requiring high-speed transmission, allowing short sampling cycles to be maintained without exceeding communication bandwidth and causing interruptions.

Inventive Principle:
Principle #10Preliminary action
