Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If bitmap or raster image formats are used for card manufacturing, then the image can be represented with high resolution to avoid blockiness, but the data processing requirements and processing time increase significantly

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent changes the fundamental parameter of image representation from bitmap/raster formats to vector formats. This parameter change allows the laser machine to process and etch images using mathematical descriptions of shapes and paths rather than processing large arrays of pixel data, thereby maintaining high image quality while significantly reducing data processing requirements and processing time.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical image processing approach (matrix printing or forming processes that require converting bitmap images to vectored motion instructions) with a direct vector format processing system. The laser machine receives vector data directly, eliminating the conversion step and enabling more efficient processing while maintaining or improving image quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If flat image formats are used with laser machines, then the image can be processed, but the boundaries are approximated leading to lower quality images with aliasing problems

Engineering Contradiction:

Improveimage processing capabilityVSAvoidimage quality

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent inverts the traditional approach by not converting images to flat bitmap formats before laser processing. Instead, it uses vector formats that inherently describe precise boundaries and paths, allowing the laser machine to etch accurate image boundaries without approximation or aliasing artifacts.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the data format parameter from raster/flat images to vector images. Vector formats store images as mathematical descriptions of paths, curves, and shapes, which provide exact boundary definitions that laser machines can follow precisely, eliminating the boundary approximation and aliasing problems inherent in flat image formats.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If continuous motion laser etching is used without vector format, then the process is simpler, but the image resolution and quality are reduced due to approximation of boundaries

Engineering Contradiction:

Improveprocess complexityVSAvoidimage resolution

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent changes the input data format parameter to vector format, which provides precise mathematical descriptions of image boundaries and paths. This parameter change enables the continuous motion laser etching process to maintain high image resolution and quality by following exact vector paths rather than approximating boundaries from flat image data.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the need for complex image processing and conversion systems with a direct vector-to-laser interface. The laser machine processes vector data natively, substituting the mechanical conversion process (from bitmap to vectored motion instructions) with a more efficient direct processing approach that maintains simplicity while improving image quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
