Solution Overview

Problem

Conventional ink-based marking devices lack the capability to create gradient tones or simultaneous markings with primary and secondary colors effectively, limiting their ability to produce complex shading and multi-tonal effects.

Innovation Solution

The development of a multi-component nib structure with varying densities and porosities, allowing for different ink flow configurations and separation mechanisms, enables the creation of gradient tones and simultaneous primary and secondary color markings from a single or multiple ink reservoirs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional single-component nib structure is used, then the device is simple in construction, but it cannot create gradient tones or multi-tonal effects

Engineering Contradiction:

Improvecapability to create gradient tones and multi-tonal effectsVSAvoidnib structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nib is divided into multiple components (first nib component and second nib component), each with different porosity characteristics. This segmentation allows different ink formulations to flow through different pathways, enabling gradient tones and multi-tonal effects while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the nib structure are assigned different porosity properties - the first nib component has a first porosity and the second nib component has a second porosity. This local differentiation enables selective ink flow control, allowing the same nib to produce varied tonal effects in different areas or under different writing conditions.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If a multi-component nib structure with varying porosity is implemented, then gradient markings and multi-tonal effects are achieved, but the manufacturing complexity increases

Engineering Contradiction:

Improveshading and color combination capabilityVSAvoidnib structure fabrication

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The first nib component and second nib component are arranged in a nested or integrated configuration where they work together as a unified nib structure. This nesting approach allows complex multi-tonal functionality to be achieved through a compact design that can be manufactured as an integrated unit or pre-assembled component, reducing overall manufacturing complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If different ink flow configurations are used through the multi-component nib, then nuanced shading is produced, but ink flow control complexity increases

Engineering Contradiction:

Improveink flow variation for shadingVSAvoidink flow separation mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ink flow control is achieved by varying the porosity parameter between the first nib component and second nib component. This parameter change approach allows different ink formulations to flow at different rates or through different pathways based on their respective porosity characteristics, producing nuanced shading effects without requiring complex mechanical flow control mechanisms.

Inventive Principle:
