Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing three-dimensional scanners require the measurement worker to frequently move between the scanner and a personal computer to confirm measurement details on a display screen, making it inconvenient to operate when the scanner is distant from the computer.

Innovation Solution

A three-dimensional measurement device with a scanner display unit that displays measurement information directly on the scanner, allowing workers to confirm distance, irradiation, and scan completion range without needing to move, using a position and posture specifying unit to generate display data based on scanner imaging and position data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the three-dimensional scanner is operated at a place distant from the personal computer, then the measurement worker can scan the measurement target more freely, but the measurement worker has to move to the personal computer to confirm measurement details, which is inconvenient

Engineering Contradiction:

Improvescanner operation flexibilityVSAvoidmeasurement confirmation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent extracts the display function from the personal computer and relocates it to the scanner itself. The scanner includes a display unit that can display measurement details such as distance, irradiation status, and scan completion range, allowing the measurement worker to confirm measurement information directly at the scanner without needing to return to the personal computer.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a display unit as an intermediary between the scanner and the personal computer. This display unit receives data from the personal computer and presents it locally at the scanner, serving as a mediator that enables independent operation and confirmation at the scanner location.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If a general display screen on a personal computer is used, then all measurement information can be displayed, but the measurement worker has to frequently move between the scanner and computer, reducing productivity

Engineering Contradiction:

Improvemeasurement information completenessVSAvoidmeasurement work efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent extracts essential measurement information display functions from the personal computer and implements them directly on the scanner's display unit. The display unit shows key measurement details including distance to target, pattern light irradiation status, and scan completion range, enabling workers to confirm measurement progress without returning to the computer.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements a partial display solution where the scanner's display unit shows only the most essential measurement information needed during scanning operations, rather than copying the complete computer display. This partial information set is sufficient for operational confirmation and eliminates the need for frequent trips to the computer.

Inventive Principle:

Principle #16Partial or excessive action

3Measurement precision

If the contact-type probe is used, then measurement coordinates can be obtained through contact, but only a limited range of the measurement target can be measured

Engineering Contradiction:

Improvecontact measurement accuracyVSAvoidmeasurement range

Core Design Contradiction:

Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent replaces the mechanical contact-type probe with a non-contact three-dimensional scanner that uses optical methods (pattern light projection and imaging) to measure coordinates. This substitution eliminates the physical contact requirement, enabling measurement of a much wider range of the measurement target including surfaces that are difficult to access with a probe.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Information regarding a measurement result of a three-dimensional scanner can be easily confirmed on a three-dimensional scanner. A three-dimensional measurement device includes a three-dimensional scanner 2, a position and posture specifying unit that specifies a position and a posture of the three-dimensional scanner 2, and a three-dimensional data generation mechanism that generates display data indicating a three-dimensional shape of a measurement target based on an image including pattern light and the position and posture of the three-dimensional scanner 2 and transmits the generated display data. The three-dimensional scanner 2 receives the display data from the three-dimensional data generation mechanism. A scanner display unit 113 displays a display screen generated based on the display data received by the three-dimensional scanner.
