Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stylus holders fail to securely protect and recharge styluses, often leaving the stylus nib exposed and lacking efficient charging solutions.
Innovation Solution
A stylus securing apparatus featuring an elastic deformable holding sleeve with magnetized elements for secure stylus retention, combined with inductive recharging capabilities, allowing for wireless power transfer and integration with portable computing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stylus holder is designed to hold the stylus, then the stylus is retained, but the stylus nib remains exposed and unprotected
Solution Approach 1:
The holding sleeve is inserted within a protective outer sleeve, creating a nested structure where the inner sleeve holds the stylus and the outer sleeve protects the nib. This nested arrangement allows the stylus to be retained while the nib remains enclosed and protected from damage.
2Reliability
If a stylus holder provides basic holding function, then the stylus is secured, but wireless charging capability is lacking
Solution Approach 1:
The holding sleeve integrates multiple functions: it provides mechanical retention of the stylus through magnetic elements while simultaneously incorporating wireless charging coils and circuitry. This merging of holding and charging functions into a single integrated apparatus eliminates the need for separate devices.
Solution Approach 2:
The holding sleeve is designed as a multi-functional device that can both secure the stylus and provide wireless recharging. The apparatus universally serves both protective/retention purposes and power supply purposes, adapting to different user needs without requiring additional accessories.
3Reliability
If magnetized elements are added to secure the stylus, then retention is improved, but the structure becomes more complex
Solution Approach 1:
The holding sleeve utilizes a flexible magnetic lining or thin magnetic film integrated into the sleeve structure, rather than discrete bulky magnets. This approach provides effective magnetic retention while maintaining a sleek, simple external form factor and minimizing structural complexity.
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 apparatus effectively secures the stylus, protects the nib, and provides convenient wireless charging, enhancing usability and convenience for mobile computing devices.
Implementation Method 1
a plurality of magnetized elements, wherein the plurality of magnetized elements is laterally spaced and disposed at least partially within a lining of the holding sleeve
Implementation Method 2
a plurality of inductive recharging elements distributed about a circumference of the holding sleeve

AI summary
An apparatus for housing and recharging a stylus (or stylus pen). The apparatus includes an elastic deformable holding sleeve which facilitates the placing and extraction of a stylus secured within a lumen of the apparatus. The stylus is further secured within the apparatus via magnetism. Additionally, or optionally, the apparatus includes an inductive recharging element, which in response to receiving direct current (DC) from an embedded battery, generates an electromagnetic field that couples with the inductive recharging circuit within a proximal stylus, thus providing electrical power or current to the secured stylus.
