Solution Overview

Problem

Conventional styluses have limited functionality, are not easily upgradable, and require replacement of entire devices when components fail, leading to increased costs and inconvenience, as they cannot be disassembled or have their functions expanded to meet user-specific needs for various touch-controlled products.

Innovation Solution

A modular stylus design with a pen body containing a control module and connection interfaces that allow for the assembly and concatenation of modular function devices, including charging, Bluetooth, and microphone modules, enabling the stylus to be extended and modified according to user requirements, with power supply capabilities that allow for charging through these modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional stylus functions are directly integrated into a single body, then the stylus structure is simple, but the stylus cannot be disassembled or have components replaced, leading to increased overall usage cost when components fail

Engineering Contradiction:
Improvestylus structure simplicityVSAvoidcomponent replaceability
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The stylus is divided into modular components including a pen body, modular function devices, and a pen head that can be independently assembled and disassembled. The connection interface enables separation between these components, allowing the pen body to be reused while replacing only the failed modular function devices or pen head, thereby reducing overall replacement costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stylus structure transitions from a fixed integrated design to a dynamic reconfigurable system. The connection interface allows the modular function devices to be attached or detached as needed, providing flexibility in configuration and enabling easy replacement of components without affecting the entire stylus structure.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If conventional stylus functions are directly integrated into a single body, then the stylus structure is simple, but the stylus cannot be upgraded or expanded to meet multi-function requirements

Engineering Contradiction:
Improvestylus structure simplicityVSAvoidfunction expandability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The stylus is divided into modular components including a pen body, modular function devices, and a pen head that can be independently assembled and disassembled. The connection interface enables separation between these components, allowing the pen body to be reused while replacing only the failed modular function devices or pen head, thereby reducing overall replacement costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection interface is designed with universal compatibility to support various types of modular function devices. This allows a single pen body to accommodate multiple different function modules (such as charging modules, Bluetooth modules, microphone modules), enabling the stylus to adapt to different touch-controlled products and user needs without requiring multiple specialized styluses.

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

3Ease of manufacture

If conventional stylus functions are directly integrated into a single body, then the stylus structure is simple, but the user must replace the entire stylus when any component fails, greatly increasing overall usage cost

Engineering Contradiction:
Improvestylus structure simplicityVSAvoidoverall usage cost
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The stylus is divided into modular components including a pen body, modular function devices, and a pen head that can be independently assembled and disassembled. The connection interface enables separation between these components, allowing the pen body to be reused while replacing only the failed modular function devices or pen head, thereby reducing overall replacement costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

When a modular function device or pen head fails, only the failed component is replaced while the pen body is recovered and reused. This selective replacement approach recovers the value of the durable pen body structure, significantly reducing the overall usage cost compared to replacing the entire integrated stylus.

Inventive Principle:
Principle #34Discarding and recovering

4Reliability

If single-function styluses are used for different touch electronic products, then each stylus is simple and reliable, but the user must purchase multiple styluses, reducing purchase willingness

Engineering Contradiction:
Improvestylus function reliabilityVSAvoidmulti-product compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connection interface is designed with universal compatibility to support various types of modular function devices. This allows a single pen body to accommodate multiple different function modules (such as charging modules, Bluetooth modules, microphone modules), enabling the stylus to adapt to different touch-controlled products and user needs without requiring multiple specialized styluses.

AI summary

A stylus includes a pen body, an internal circuit, at least one modular function device, and a pen head disposed at a lower part of the pen body and including a first conductive part. The modular function device includes a circuit module disposed inside a main body thereof and electrically connected to connection interfaces disposed on upper and lower sides of the main body, respectively. The connection interface of the modular function device can be mounted on the adapted connection interface of the pen body, and two adjacent modular function devices can be concatenated with each other through the adapted connection interfaces thereof. As a result, according to the user's requirement, the stylus can be extended with various modular function devices, and the modular function device mounted on the stylus can also be replaced.
