Solution Overview

Problem

Existing calibratable tools face challenges in ensuring safe, easy, and fast calibration processes, often leading to incorrect calibration and potential damage due to manual errors and the need for physical calibration certificates.

Innovation Solution

A calibratable tool equipped with a non-volatile storage medium and display device that receives and displays the next calibration date from a calibration device, automatically calculating and updating this date based on a fixed or definable period, and providing a warning message when recalibration is due, thereby eliminating the need for manual certificates and enhancing the calibration process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual calibration certificate handling is used, then flexibility and simplicity are maintained, but errors occur and reliability decreases

Engineering Contradiction:
Improvecalibration accuracyVSAvoidmanual certificate handling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The tool automatically manages its own calibration certificate information by storing the next calibration date in its internal storage medium and displaying it through its own display device, eliminating the need for external manual certificate handling and reducing human error

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of printing, affixing, and manually tracking physical calibration certificates with an electronic system that stores and displays calibration date data directly in the tool's memory and display interface

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If calibration date is stored and displayed in the tool, then time is saved and productivity increases, but device complexity increases

Engineering Contradiction:
Improvecalibration process speedVSAvoidstorage medium and display device
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent utilizes existing universal components in modern tools - non-volatile storage media and display devices - which are already integrated into many electronic tools for other functions, thereby minimizing additional complexity while enabling automated calibration date management

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The calibration device transmits the next calibration date data to the tool's storage medium, creating a digital copy of the calibration information that can be stored and displayed without requiring physical certificate handling

Inventive Principle:
Principle #26Copying
