Solution Overview

Problem

Existing systems fail to efficiently and intuitively allow users to access and display measurement data from multiple devices within a plant environment, requiring manual connection and individual data retrieval.

Innovation Solution

A system comprising a detection unit to identify the target device based on user gaze, an acquisition unit to retrieve measurement data from associated storage addresses, and a display unit to present the data, integrated into a wearable terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual connection and individual data retrieval methods are used, then data access is possible, but operational efficiency is reduced and the process becomes complex

Engineering Contradiction:

Improveoperational efficiencyVSAvoidmanual connection process

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system enables automatic device identification and data retrieval through gaze detection. The wearable terminal automatically detects which device the user is looking at and retrieves the corresponding measurement data without requiring manual connections or input, allowing the system to serve itself rather than requiring user intervention for each data access operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations (physical connections, button presses, navigation) with optical detection (gaze tracking). The detection unit captures the user's line of sight and automatically identifies the target device, substituting the mechanical interaction process with an optical field-based detection method that is faster and more intuitive.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If traditional data access methods are used, then data can be retrieved, but the process requires multiple steps and time

Engineering Contradiction:

Improvedata access timeVSAvoiddata access simplicity

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The system performs preliminary actions by continuously monitoring the user's gaze direction and pre-identifying the target device before data retrieval is explicitly requested. The detection unit tracks the line of sight in real-time, so when the user looks at a device, the system has already prepared to retrieve the data, eliminating the need for separate selection and access steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The wearable terminal acts as an intermediary between the user and the measurement data. Instead of the user directly interacting with multiple devices or complex interfaces, the terminal captures the gaze information, translates it into device identification, retrieves the corresponding data from storage, and presents it to the user, simplifying the entire interaction chain.

Inventive Principle:

Principle #24Intermediary (Mediator)
