Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical samples are kept in a library for material reference, then material information is preserved, but accessibility and collaboration efficiency deteriorate due to shipping requirements and location constraints

Engineering Contradiction:
Improvematerial information preservationVSAvoidcollaboration efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent creates digital copies of physical material samples through photography and scanning processes. These digital replicas preserve all visual and textural information of the original materials while eliminating the need for physical shipping and handling, enabling instant access and collaboration among designers regardless of their physical locations.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical system of physical sample storage, retrieval, and shipping with a digital information system. Instead of physically transporting material samples between locations, the system uses digital images and data files that can be instantly transmitted and accessed, substituting physical logistics with information technology.

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

2Quantity of substance

If manufacturer descriptions are used for material information, then basic material data is provided, but specificity and design utility deteriorate due to non-standardized nomenclature and lack of detail

Engineering Contradiction:
Improvematerial information availabilityVSAvoidmaterial description specificity
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent transforms material information from standardized physical parameters (color codes, material composition, texture characteristics) captured in digital images and metadata into a universal reference framework. This allows precise description and comparison of materials regardless of manufacturer-specific nomenclature, enabling accurate material selection and substitution based on objective measurable properties.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If flatbed scanners are used for material capture, then digital images of materials are produced, but portability and image quality deteriorate due to fixed location requirement and poor performance with textured materials

Engineering Contradiction:
Improvedigital material dataVSAvoidportability and adaptability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent transitions from a static, fixed-location scanning system to a dynamic, portable imaging system using mobile devices. The system adapts to various shooting conditions and material types through flexible positioning and multiple capture angles, allowing designers to capture material data on-site without returning to a fixed scanning laboratory.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent adds the dimension of portability and spatial flexibility to material capture by using handheld mobile devices instead of fixed flatbed scanners. This enables three-dimensional positioning and多角度 (multi-angle) capture of materials in their natural contexts, rather than requiring flat, two-dimensional placement on a scanner bed.

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

4Ease of operation

If handheld devices are used for material capture, then portability and accessibility are improved, but image alignment and quality deteriorate due to lens aberrations and orientation inconsistencies

Engineering Contradiction:
ImproveportabilityVSAvoidimage alignment accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent incorporates alignment markers and reference features in the captured images that provide feedback information for automated correction processes. The system detects these markers, calculates orientation and perspective deviations, and automatically adjusts the images to achieve consistent alignment, compensating for the inherent inaccuracies of handheld device photography.

Inventive Principle:
Principle #23Feedback

AI summary

A material data collection system allows capturing of material data. For example, the material data collection system may include digital image data for materials. The material data collection system may ensure that captured digital image data is properly aligned, so that material data may be easily recalled for later use, while maintaining the proper alignment for the captured digital image. The material data collection system may include using a capture guide, to provide cues on how to orient a mobile device used with the material data collection system.
