Stylus Pen Integrating Camera and Touch Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stylus pens have limited functionality, primarily offering basic touch screen functionality, which is inconvenient for users of miniaturized portable electronic devices, as they lack versatility and practicality.
Innovation Solution
A stylus pen design incorporating a hollow pen body with an electromagnetic touch pen module, a camera module, a rechargeable battery pack, and a function button, allowing switching between camera and touch pen modes via a power button, with the function button serving as a shutter button or right mouse button, and enabling image transmission via a USB connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stylus pen is designed with multiple functions (camera module, electromagnetic touch pen module), then the versatility and practicality of the stylus pen is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (camera module, electromagnetic touch pen module, lighting module, USB connector) into a single stylus pen body, integrating components that would traditionally be separate devices. This merging approach directly addresses the contradiction by consolidating multiple functionalities into one device structure.
Solution Approach 2:
The stylus pen is designed as a universal device that can perform multiple functions: photography, touch screen interaction, and data transmission. The single device serves multiple purposes that would otherwise require separate tools, directly implementing the multi-functionality principle to resolve the versatility-complexity contradiction.
2Weight of moving object
If electronic devices are miniaturized to reduce size and weight, then portability is improved, but the area for controlling keys is reduced, causing inconvenience for users
Solution Approach 1:
The patent replaces traditional mechanical controlling keys with a touch screen interface that can be operated by the stylus pen. The electromagnetic touch pen module enables interaction with the touch screen without requiring physical buttons, thus maintaining ease of operation while allowing device miniaturization.
Solution Approach 2:
The stylus pen serves as both a writing tool and a control interface for the touch screen, eliminating the need for separate controlling keys on the device. This multi-functional approach allows the device to remain compact while maintaining full operational capability.
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
Enhances the practicality of the stylus pen by providing multiple functions, such as touch screen interaction and photography, improving user experience through enhanced functionality and convenience.
Implementation Method 1
The first circuit board electrically connects with the electromagnetic pen head for controlling the electromagnetic pen head to output corresponding electromagnetic signals
Implementation Method 2
The rechargeable battery pack is disposed in the pen body and connected with both the first circuit board and the second circuit board to supply power for the electromagnetic touch pen module and the camera module
