Individual Device Identification Through Visible Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axial force measurement methods for fastening members, such as bolts, require physical measurements that are labor-intensive and cannot be performed remotely, leading to inefficiencies and safety risks due to the need for close proximity.
Innovation Solution
An individual identification system with sensing devices that include visible identifiers, capable of being recognized through image identification, which display information reflecting the physical state of the member or surroundings, allowing remote and instant visualization of changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If axial force measurement is performed by measuring physical change of outer shape, then axial force can be calculated, but measurement requires close proximity and takes a lot of effort
Solution Approach 1:
The patent replaces the mechanical measurement system (physical contact and direct measurement of outer shape changes) with an optical/image recognition system. The identifier on the bolt head contains encoded information about axial force, allowing remote reading through image capture and processing without physical contact or close proximity measurement
Solution Approach 2:
The patent creates an optical copy (image) of the identifier information embedded on the bolt head. Instead of measuring physical deformation directly, the system captures an image of the identifier pattern and decodes the axial force information from it, enabling remote and convenient measurement
2Measurement precision
If axial force measurement is performed by measuring physical change of outer shape, then axial force can be calculated, but measurement must be performed in close state
Solution Approach 1:
The patent replaces complex mechanical measurement equipment and procedures with a simple image capture and processing system. The identifier on the bolt head encodes axial force information that can be read remotely using standard imaging devices, eliminating the need for specialized close-proximity measurement tools

AI summary
An identification system has one or more sensing devices each having an identifier, and an individual identification apparatus for performing individual identification of the devices. The devices are each provided with a visual confirmation part that can be visually confirmed from the outside. The individual identification apparatus is provided with an image identification means capable of identifying the visual confirmation parts of the devices as image information. The display content of the visual confirmation parts is read by the image identification means to acquire the identifiers.
