Solution Overview

Problem

Existing methods for mechanically connecting line elements, such as pipes or cables, lack assurance and verification of the materials used and the type of tools employed, leading to potential safety and quality issues.

Innovation Solution

Incorporating marking elements with identification information on both line elements and pressing tools, which are detected before establishing a mechanical connection, ensuring that the connection can only be made if the identification information is recorded and verified, thereby guaranteeing the use of correct materials and tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If marking elements with identification information are incorporated on line elements and pressing tools, then verification and traceability of materials and tools is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improveverification of materials and toolsVSAvoidcomplexity of connection system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The marking elements with identification information are applied to line elements and pressing tools before the connection process. The detection device reads this information in advance to verify compatibility and authorization, ensuring that only verified combinations can proceed with the mechanical connection. This preliminary verification step prevents unauthorized or incompatible connections while maintaining a relatively simple overall system architecture.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If detection device is added to verify identification information before connection, then connection safety and quality control are improved, but manufacturing cost and device complexity increase

Engineering Contradiction:

Improveconnection safetyVSAvoidmanufacturing cost of pressing device

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The detection device replaces manual verification processes with automated optical or electromagnetic reading of identification information on marking elements. This substitution eliminates the need for human inspection while providing consistent, reliable verification of material and tool compatibility, improving connection safety without requiring complex mechanical verification mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The marking elements on line elements and pressing tools contain their own identification information that automatically identifies and characterizes the components. The detection device simply reads this self-provided information to verify compatibility, eliminating the need for external verification systems or manual documentation checks, thereby controlling manufacturing costs.

Inventive Principle:

Principle #25Self-service

3Loss of information

If multiple marking elements and detection steps are implemented, then traceability and documentation capability are improved, but processing time and productivity decrease

Engineering Contradiction:

Improvetraceability of connection processVSAvoidconnection production speed

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The identification information is pre-applied to marking elements on line elements and pressing tools during manufacturing. The detection device reads this information in advance before the actual connection process, so that verification and documentation occur without interrupting or slowing down the subsequent mechanical connection operations, maintaining high productivity while achieving complete traceability.

Inventive Principle:

Principle #10Preliminary action
