Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If makeshift arrangements (zip ties, adhesive pads) are used to install measurement coils, then installation is simple, but the measurement coil lacks stability and is susceptible to contact with the electrical wire

Engineering Contradiction:
Improveinstallation simplicityVSAvoidmeasurement coil stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A dedicated installation tool acts as an intermediary device between the measurement coil and the electrical wire. This tool provides a stable mounting mechanism that securely positions the measurement coil without requiring direct attachment to the wire, thereby maintaining both ease of installation and measurement stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The installation system is divided into separate functional components: the measurement coil itself, the installation tool for positioning, and the mounting mechanism. This segmentation allows each component to be optimized independently - the coil for measurement accuracy and the tool for stable installation.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If skilled technicians perform installation with power off, then measurement accuracy is ensured, but the process is time-consuming and labor-intensive

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidinstallation efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The installation tool is designed with pre-configured positioning features and guidance mechanisms that automatically center and align the measurement coil during installation. This preliminary preparation of the installation mechanism eliminates the need for manual centering adjustments by skilled technicians, maintaining accuracy while speeding up the process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The installation tool incorporates self-aligning and self-centering mechanisms that automatically position the measurement coil correctly without requiring skilled manual intervention. The tool performs the complex positioning tasks automatically, making the installation process both accurate and efficient.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If standardized measurement coils are used, then installation is readily performed on distantly placed wires, but in congested spaces coils overlap causing voltage interference

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidvoltage interference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The installation tool is designed with adjustable and flexible positioning capabilities that allow it to adapt to congested spatial environments. The tool can dynamically adjust the position and orientation of the measurement coil to avoid overlap with nearby coils or wires, thereby preventing voltage interference while maintaining installation versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The installation tool provides localized positioning control for the measurement coil, allowing precise placement in specific congested areas. This localized adjustment capability ensures that each measurement coil is positioned optimally in its specific location, avoiding interference from nearby components while maintaining overall system versatility.

Inventive Principle:
Principle #3Local quality

4Manufacturing precision

If measurement coils require substantial centering effort, then positioning accuracy can be achieved, but significant time and labor are required

Engineering Contradiction:
Improvepositioning accuracyVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The installation tool incorporates pre-configured centering mechanisms and guidance features that automatically position the measurement coil at the correct location and orientation. This preliminary preparation of the installation mechanism eliminates the need for time-consuming manual centering adjustments, achieving positioning accuracy efficiently.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The installation tool replaces manual mechanical centering operations with automated positioning mechanisms. These mechanisms use engineered guides, alignment features, and mechanical advantages to achieve precise centering automatically, substituting skilled manual labor with a designed mechanical system that is both accurate and time-efficient.

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