Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a web browser interface is used for electrical design tools, then design parameter input and circuit selection functionality is provided, but usability on mobile devices is poor

Engineering Contradiction:
Improvedevice compatibilityVSAvoidmobile usability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional mechanical keyboard input interface with an optical image capture interface. Users can photograph schematics or write design parameters on paper, and the system optically recognizes and processes this information, enabling seamless mobile device usage while maintaining full design tool functionality.

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

Solution Approach 2:

The system creates a universal interface that works across both desktop and mobile devices. The image capture device serves multiple functions: capturing handwritten parameters, photographing schematics, and transmitting data to the design engine, making the tool equally effective on any device type.

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

2Measurement precision

If manual typing of design parameters is required, then precise parameter input is achieved, but time consumption and operational complexity increase

Engineering Contradiction:
Improveparameter input accuracyVSAvoidparameter extraction time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system allows users to prepare design parameters in advance by writing them on paper or drawing schematics, then capture them all at once using the image capture device. This preliminary preparation followed by bulk capture reduces the overall time compared to sequential typing while maintaining accuracy through optical recognition.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates an optical copy of the design parameters and schematics from physical paper or whiteboard drawings. This digital copy is then processed by the design engine, eliminating the need for manual transcription while preserving the original information accurately.

Inventive Principle:
Principle #26Copying

3Device complexity

If desktop-based design tools are used, then comprehensive design functionality is provided, but collaboration and instant delivery in team environments are limited

Engineering Contradiction:
Improvedesign tool functionalityVSAvoidcollaboration capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent adds the dimension of mobile accessibility to the traditional desktop design tool. By implementing an image capture interface that works on mobile devices, the system enables designers to access and use comprehensive design tools in previously inaccessible locations such as conference rooms, facilitating real-time collaboration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The mobile device with image capture capability serves as an intermediary between the physical design discussion environment (whiteboard, paper) and the digital design engine. This intermediary enables seamless integration of collaborative physical discussions with computational design analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)
