Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional measurement devices require repetitive and burdensome operation procedures for measuring multiple objects with the same shape, leading to potential errors with increased measurement frequency, as each object's geometric elements and dimensions need to be designated individually.
Innovation Solution
A three-dimensional measurement device that stores model shape data and operation procedures as a template, allowing for automatic alignment and dimension measurement of subsequent objects by specifying relative positional relationships between geometric elements, reducing the need for individual designation and enhancing operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dimension measurement is performed on each measurement target object individually by designating geometric elements and measurement positions, then measurement accuracy is maintained, but operation burden increases and operability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-storing the operation procedures and geometric element designations for a model object in advance. When measuring similar objects, the stored template is automatically applied, eliminating the need to repeatedly designate geometric elements and measurement positions for each object, thus reducing operation burden while maintaining measurement accuracy
Solution Approach 2:
The patent uses copying by creating a template from a model object's three-dimensional shape data and measurement procedures. This template is then copied and applied to subsequent measurement target objects with similar shapes, allowing automatic alignment and measurement without manual re-designation of geometric elements, thereby improving operability while preserving measurement precision
2Reliability
If the same measurement operations are repeated multiple times for different objects, then comprehensive measurement coverage is achieved, but operation errors increase
Solution Approach 1:
The patent implements self-service by enabling the measurement system to automatically align and measure new objects using the stored template without requiring manual intervention for each measurement. The system self-corrects and self-applies the measurement procedure, reducing human error and improving measurement consistency across multiple objects while maintaining high productivity
Solution Approach 2:
The patent applies feedback by using the stored template as a reference standard against which subsequent measurements are compared. The system automatically adjusts and aligns new objects based on the template, providing continuous feedback to ensure measurement consistency and reduce errors across multiple measurements
3Adaptability or versatility
If geometric elements and measurement positions are designated manually for each object, then measurement flexibility is maintained, but time consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-defining and storing the optimal geometric elements and measurement positions in the template during the initial model creation phase. This preliminary setup allows rapid automated application to subsequent objects, significantly reducing time consumption while maintaining the flexibility to adapt to different measurement scenarios through template modification

AI summary
A three-dimensional measurement device which is capable of increasing the operability at the time of repeatedly performing dimension measurement for a plurality of measurement target objects having substantially the same shape is provided. There are included a template storage unit for storing, as a template, model three-dimensional shape data and an operation procedure of dimension measurement performed on the model three-dimensional shape image, and a positional relationship specification unit for specifying a relative positional relationship between the model three-dimensional shape data and measurement three-dimensional shape data. The geometric element extraction unit specifies a geometric element of a measurement three-dimensional shape based on the relative positional relationship and the template, and the dimension value calculation unit performs dimension measurement on the measurement three-dimensional shape based on the relative positional relationship and the template.
