Solution Overview

Problem

Existing pen cups fail to securely store and transport different types of pens, such as felt pens and paint markers, without risking the pens drying out or being lost, and they require multiple cups for various activities, increasing logistical effort.

Innovation Solution

A pen holder with a multi-part base and a density section that can adapt to pens of different diameters, allowing for safe storage and transport of various pen types while preventing them from drying out.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pen holder is tailored to a specific pen model to ensure secure storage and prevent drying out, then the sealing and protection are improved, but the adaptability to different pen models deteriorates

Engineering Contradiction:
Improvesealing effectivenessVSAvoidcompatibility with different pen models
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sealing section is designed to be movable and adjustable within the base body, allowing it to change position and adapt to different pen diameters. This dynamic adjustment mechanism enables the same pen holder to maintain effective sealing across multiple pen models rather than being fixed for a single model.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sealing section can change its physical parameters (position, orientation, contact pressure) to match different pen dimensions. By varying these parameters, the sealing interface adapts to different pen diameters while maintaining the necessary seal quality to prevent drying out.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If multiple pen holders are purchased for different activities and pen types, then the suitability for specific tasks is improved, but the logistical burden and device complexity increase

Engineering Contradiction:
Improvetask-specific suitabilityVSAvoidnumber of pen holders required
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pen holder is designed with universal adaptability through its adjustable sealing section, enabling a single device to perform multiple functions across different activities and pen types. This eliminates the need for users to purchase and manage multiple specialized pen holders for different tasks.

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

Solution Approach 2:

The pen holder is divided into functional segments (base body, sealing section, insertion opening) where the sealing section can be independently adjusted. This segmentation allows the device to adapt to different requirements without changing the entire structure, reducing the need for multiple complete pen holder units.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If a pen holder uses a fixed sealing section design, then the manufacturing simplicity is improved, but the adaptability to different pin diameters deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidcompatibility with different pin diameters
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

Rather than manufacturing multiple fixed sealing sections for different diameters, the design uses a single sealing section that can dynamically adjust its position and configuration. This reduces manufacturing complexity while achieving adaptability through the adjustable mechanism rather than through producing varied components.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The pen holder effectively stores and transports multiple pen types securely, preventing drying out and loss, and reduces the need for multiple cups by accommodating pens of varying diameters.

Implementation Method 1

The sealing section is or are provided and designed to receive at least a first pin with a first, larger diameter and a second pin with a second, smaller diameter, i.e. pins of different diameters, and to contact them in a (radially) sealing manner
