Solution Overview

Problem

Existing mobile terminal test systems face challenges in efficiently correcting the position of mobile terminals due to aging deterioration of positioners or incorrect attachments, leading to decreased work efficiency and measurement accuracy.

Innovation Solution

A mobile terminal test apparatus equipped with a reception antenna, positioner, camera, and control unit that stores and compares image data to facilitate position correction by displaying errors when deviations occur, using a database to manage Peak point data for improved accuracy and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If position information is obtained from past results and the position of the mobile terminal is adjusted, then measurement time is reduced, but position accuracy deteriorates due to aging deterioration of the positioner or incorrect attachment

Engineering Contradiction:
Improvemeasurement timeVSAvoidposition accuracy
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The system performs preliminary Peak point searches and stores the results in a database before actual measurements. When the same measurement conditions are encountered again, the pre-stored position information is retrieved and used to quickly position the mobile terminal, significantly reducing measurement time while maintaining accuracy through visual verification

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The camera captures images of the mobile terminal's current position and compares them with the stored Peak point position images. This visual feedback mechanism allows operators to verify whether the positioner has correctly positioned the terminal, and to make manual adjustments if deviations are detected, thereby maintaining position accuracy despite positioner aging or attachment issues

Inventive Principle:
Principle #23Feedback

2Device complexity

If manual correction of position deviation is performed using only position information such as angle, then device complexity is reduced, but work efficiency deteriorates and measurement accuracy decreases

Engineering Contradiction:
Improvecorrection system complexityVSAvoidwork efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

A camera is introduced as an intermediary tool to capture images of the mobile terminal's position. These images serve as a visual mediator between the positioner's numerical control and the actual physical position of the terminal, enabling operators to quickly assess positioning accuracy and make corrections without complex measurement procedures

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates visual copies (images) of the mobile terminal's position at the Peak point and stores them in the database. During subsequent measurements, these stored images are retrieved and displayed for comparison with current position images, providing a simple yet effective reference for position correction without requiring complex measurement equipment

Inventive Principle:
Principle #26Copying

AI summary

The mobile terminal test apparatus includes a positioner that adjusts a position of UE, a camera that captures an image of a state of the position of the UE controlled by the positioner, and a control unit that sets the position of the positioner with data on a Peak point of a transmission radio wave in a database, and then compares the current image data of the UE obtained by image capturing of the camera and image data of the Peak point of a transmission radio wave in the database, and displays the current image data of the UE obtained by image capturing of the camera and the image data of the Peak point of the transmission radio wave in the database when an error is greater than a predetermined threshold value.
