Solution Overview

Problem

The existing technique for creating mosaic-type structures with engraved panels is expensive due to the need for precise machining, limiting the range of images that can be offered as the process requires significant resources and time, especially for large panels.

Innovation Solution

A set of individual elements with formations that create areas of varying luminance based on gray levels, allowing for the reproduction of images through the assembly of these elements, which can be used to create complex images without the need for a custom matrix, enabling the use of standard elements and reducing production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If precise machining of a custom matrix is performed to create engraved panels, then manufacturing precision and image quality are improved, but production cost and time consumption increase significantly

Engineering Contradiction:
Improveimage qualityVSAvoidproduction cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The invention divides the image reproduction task into multiple discrete tiles, each containing a portion of the overall image. This segmentation eliminates the need for a single large custom matrix, allowing instead the use of smaller standard matrices that can be reused across multiple images, thereby reducing manufacturing cost while maintaining image quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses photogrammetric data to create digital models of the image, which are then used to generate the tile patterns without requiring physical machining of custom matrices. This digital copying approach replaces expensive mechanical machining with computational processes, significantly reducing production costs.

Inventive Principle:
Principle #26Copying

2Area of stationary object

If the panel size is increased to accommodate large images, then the适用范围 is improved, but the number of furrows required increases, amplifying the machining cost and time

Engineering Contradiction:
Improvepanel sizeVSAvoidmachining cost
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

Large panels are divided into multiple smaller tiles that can be produced using standard matrices. Each tile is manufactured independently and then assembled to form the complete large-scale image, avoiding the need for expensive large-format custom machining while maintaining the desired panel size.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Standard matrices are designed to be universal tools that can produce multiple different images by varying the tile arrangement and photogrammetric data input. This multi-functionality allows the same matrix to serve across numerous projects, dramatically reducing the amortized cost per image compared to custom matrices.

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

3Measurement precision

If the number of furrows is increased to achieve satisfactory image precision, then measurement precision is improved, but the machining operation becomes more tedious and expensive

Engineering Contradiction:
Improveimage precisionVSAvoidmachining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The invention uses digital photogrammetric models to precisely define the tile patterns and image reproduction requirements without requiring extensive physical machining. The digital data can be rapidly adjusted and reproduced, eliminating the time-consuming iterative process of machining increasing numbers of furrows to achieve desired precision.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The invention changes the fundamental parameters of image reproduction from continuous engraved furrows to discrete tile assemblies with standardized dimensions. This parameter change allows precision to be controlled through digital design and tile selection rather than through increasing the number of machined furrows, significantly reducing machining time.

Inventive Principle:
Principle #35Parameter changes
