Solution Overview

Problem

Existing techniques for testing lighting equipment performance often result in incorrect measurements due to issues like the measuring device being hidden or facing the wrong direction, leading to abnormal values.

Innovation Solution

An electromagnetic wave measuring device comprising a measurement data receiving unit, an abnormal value detecting unit, and a display controlling unit that receives data from multiple positions, detects abnormal values, and displays the position of measurement on a screen, along with relative positional relationships, allowing for effective highlighting and remeasurement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If measurement is performed at multiple positions, then measurement coverage is improved, but abnormal values due to incorrect positioning increase

Engineering Contradiction:

Improvemeasurement coverage areaVSAvoidmeasurement accuracy

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The system displays the measured position on a screen and provides feedback when an abnormal value is detected. The operator can see where the measurement was taken and whether it is within the correct range, allowing them to adjust their positioning and remeasure if necessary. This feedback loop prevents incorrect measurements from being accepted and ensures measurement accuracy across the expanded measurement area.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If operator manually positions measuring device, then measurement flexibility is improved, but positioning accuracy deteriorates

Engineering Contradiction:

Improvemeasurement flexibilityVSAvoidpositioning accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system replaces manual mechanical positioning judgment with automated position detection technology. A position detection device automatically determines the measured position, and the control device displays this position on a screen. This substitution of mechanical judgment with automated detection maintains measurement flexibility while significantly improving positioning accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If abnormal values are not detected, then measurement process speed is improved, but data reliability deteriorates

Engineering Contradiction:

Improvemeasurement process speedVSAvoiddata reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs self-checking by automatically detecting abnormal values through the control device. When an abnormal value is detected, the system automatically provides feedback and allows for remeasurement. This self-service approach to quality control maintains fast measurement processing while ensuring data reliability, as the system actively identifies and flags problematic measurements without requiring manual verification of each data point.

Inventive Principle:

Principle #25Self-service
