Solution Overview

Problem

Existing badge manufacturing methods do not effectively utilize the decorative effect of circular brushed surfaces to enhance visual elements like light sources, idols, or moving bodies, often resulting in static radial lines that do not align with dynamic optical radiation effects.

Innovation Solution

A badge design where a print layer with a defined radial center point is laminated onto a circular brushed surface, ensuring the radial center point coincides with the circular processing center, creating an optical radiation and diffusion effect that enhances visual elements, such as light sources or idols, and eliminates the need for static radial lines on the print layer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If static radial lines are printed on the print layer to represent light emission or motion, then the visual representation is clear and defined, but the visual effect becomes static and lacks dynamic interaction with light

Engineering Contradiction:
Improvevisual effectVSAvoiddynamic response to light
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical/printing approach of creating static radial lines with an optical approach using circular brushed surfaces. Instead of printing radial lines onto the badge surface, the invention uses circular brushing to create concentric circular patterns that interact dynamically with incident light, substituting a static printing system with a dynamic optical system that responds to light incidence angles and viewer perspective.

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

Solution Approach 2:

The patent introduces dynamics by using circular brushed surfaces that create optical effects varying with light incidence and viewing angle. The concentric circular patterns on the processed layer interact with light to produce dynamic visual effects that change as the badge is viewed from different angles or under different lighting conditions, transforming the static visual representation into a dynamic one.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If radial lines are printed on the print layer, then the radial representation is fixed and clear, but it creates a mixture of static printed lines and dynamic optical effects that reduces visual quality

Engineering Contradiction:
Improvealignment of radial center pointsVSAvoidvisual quality of optical effect
Core Design Contradiction:
Manufacturing precisionVSIllumination intensity

Solution Approach 1:

The patent extracts the radial line representation from the print layer and relocates it to the processed layer through circular brushing. By removing the radial lines from the printed subject image and creating them instead as circular brushed patterns on a separate layer, the invention eliminates the conflict between static printed lines and dynamic optical effects, allowing each layer to fulfill its optimal function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the badge into distinct functional layers: a print layer containing the subject image without radial lines, and a processed layer with circular brushed surfaces that generate the radial optical effects. This segmentation allows independent optimization of each layer - the print layer maintains manufacturing precision for image placement, while the processed layer provides dynamic optical quality through circular brushing.

Inventive Principle:
Principle #1Segmentation

3Illumination intensity

If circular processing is applied to enhance light diffusion effects, then the optical radiation effect is improved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improveoptical radiation and diffusion effectVSAvoidmanufacturing process complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent merges the decorative circular brushing process with the functional requirement for light diffusion. By applying circular processing to create concentric circular patterns, the invention simultaneously achieves both aesthetic enhancement and optical functionality in a single manufacturing step, rather than adding separate processes for decoration and light diffusion.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The circular brushed surface serves multiple functions: it provides decorative enhancement, creates optical radiation effects, and enables light diffusion. This multi-functional element reduces overall manufacturing complexity by consolidating multiple requirements into a single processed layer that accomplishes several objectives simultaneously.

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

AI summary

A badge (10) has a print layer (30) and a substrate (20) that is a processed layer. The print layer (30) is printed with a subject image (32) in which a radial center point (38) is defined as a center point of a radial representation. The substrate (20) has a circular brushed surface (22) that is subjected to circular processing. At least one of the print layer (30) and the substrate (20) is light transmissive. The print layer (30) is laminated on the circular brushed surface (22) side of the substrate (20) such that the radial center point (38) of the subject image (32) and a circular processing center point (28) that is a center point of the circular processing coincide with each other.
