Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for documenting information about objects, such as machining tools, fail to meet the increasing demands for secure data sharing and cooperation among various actors, particularly in terms of security and data integrity.

Innovation Solution

A method and system that create a data record with multiple data levels, each protected by an electronic key, allowing selective access and transfer, enabling secure data sharing and management throughout the product life cycle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If information is protected by a single password on a cloud server, then security is provided, but access control for multiple actors with different permission levels cannot be adequately managed

Engineering Contradiction:

Improvedata securityVSAvoidaccess control for multiple actors

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the data record into multiple data levels (first data level, second data level, etc.), where each level can be independently protected by different electronic keys. This allows different actors to access only the data levels appropriate to their role and permission level, resolving the contradiction between maintaining security and enabling differentiated access control.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If data is transferred between entities, then cooperation and data sharing are enabled, but transfer errors and security risks increase

Engineering Contradiction:

Improvedata sharing among actorsVSAvoiddata transfer accuracy and security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates electronic copies of the data record that can be transferred between entities without moving the original data. Each entity receives a copy with appropriate access rights encoded in electronic keys, eliminating transfer errors while enabling data sharing. The copy mechanism ensures data integrity is maintained across multiple actors.

Inventive Principle:

Principle #26Copying

3Loss of information

If all data is made accessible to all actors, then complete information sharing is achieved, but security and confidentiality are compromised

Engineering Contradiction:

Improveinformation availabilityVSAvoiddata confidentiality

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent applies local quality by assigning different access permissions to different data levels within the same data record. Each data level has its own security characteristics and access requirements. This allows complete information availability within each local level while maintaining overall confidentiality through hierarchical access control based on electronic keys.

Inventive Principle:

Principle #3Local quality

AI summary

The invention relates to a method and a system for documenting information about an object, such as a machining tool, for example. The method comprises: creating a data record for an object, said data record having at least one data category, wherein the at least one data category enables the creation of multiple data levels; creating an additional data level during the course of transferring the object and the data record to a user, each of which can be protected by an electronic key; and using the object and storing information acquired when using the object in the additional data level.
