Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If 3D printing is used to produce objects with fine detail, then manufacturing precision is improved, but production time increases significantly

Engineering Contradiction:
Improvefine detailVSAvoidproduction time
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-calculating and storing build time estimates before the actual 3D printing process begins. The system determines printing parameters, layer counts, and estimated completion times in advance, allowing users to plan and manage print jobs more efficiently without extending the actual production time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring the 3D printing process and comparing actual progress against predicted timelines. The build time estimation system provides real-time updates and adjusts predictions based on actual printing speed variations, enabling dynamic schedule management and improving overall productivity through better time allocation.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple data files with different dimensions are used, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvescaling capabilityVSAvoidprocess complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by systematically varying dimensional parameters through the proportionality factor while maintaining consistent printing parameters. The system automatically adjusts scale, layer height, and infill density based on the proportionality factor, allowing multiple objects of different sizes to be printed using the same configured parameters, thus reducing device complexity despite handling multiple data files.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements universality by creating a standardized workflow that handles multiple data files with different dimensions through a single proportionality factor calculation process. The same printing parameters and material settings can be applied across different object sizes, making the system versatile for various print jobs while maintaining process simplicity through automated scaling.

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

3Productivity

If build time is reduced, then productivity is improved, but manufacturing precision may deteriorate

Engineering Contradiction:
Improvebuild timeVSAvoiddetail quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by making the layer height adaptive rather than fixed. The system automatically adjusts layer height based on object size and detail requirements calculated from the proportionality factor. Smaller objects with higher detail requirements receive finer layer heights, while larger objects use coarser layers, optimizing both build time and manufacturing precision dynamically for each specific print job.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements local quality by applying different layer heights to different regions or objects based on their specific requirements. The proportionality factor determines the appropriate layer height for each object, ensuring that areas requiring fine detail receive higher precision while other areas use faster, coarser layers, thus balancing overall productivity with localized manufacturing precision.

Inventive Principle:
Principle #3Local quality

AI summary

A method includes identifying a first data file that includes first dimensions that may be used by a three-dimensional printer to form a physical three-dimensional model of a first object, identifying a second data file that includes second dimensions that may be used by a three-dimensional printer to form a physical three-dimensional model of a second object, determining a proportionality factor between the first dimensions and the second dimensions, multiplying the dimensions in the second data file by the proportionality factor, and causing the three-dimensional printer to form a physical three-dimensional model of the second object using the scaled dimensions.
