Motorized Stylus Ejection Wheel to Prevent Sticking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with protrusions for ejecting peripheral elements, such as stylus pens, often experience sticking issues, making it difficult for users to unload the stylus pens from the housing.
Innovation Solution
An electronic device design featuring a housing with a first wheel and a driving unit that automatically ejects the peripheral element by rotating the wheel to move it from a first position to a second position, utilizing a vibration alert driving motor, eccentric element, and clutch mechanism to provide kinetic energy and control the ejection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protrusion mechanism is used for stylus ejection, then the stylus can be manually ejected, but the protrusion often gets stuck making it difficult to push
Solution Approach 1:
The patent replaces the manual mechanical protrusion system with an automated motor-driven wheel system. The driving motor rotates the first wheel to automatically push the stylus out, eliminating the need for manual user interaction and the associated reliability issues of stuck protrusions.
Solution Approach 2:
The system performs self-service ejection where the driving motor automatically activates the wheel mechanism to eject the stylus without requiring user intervention. The clutch mechanism enables the system to autonomously control when the ejection occurs based on operational conditions.
2Ease of operation
If automatic ejection mechanism is implemented, then user convenience is improved, but device complexity increases
Solution Approach 1:
The ejection mechanism is segmented into distinct functional modules: a driving motor for power generation, a clutch mechanism for controlled power transmission, and a first wheel for actual stylus ejection. This modular segmentation allows each component to be optimized independently while maintaining overall system manageability.
Solution Approach 2:
The driving motor serves multiple functions: it provides kinetic energy for stylus ejection, generates vibration alerts, and can be controlled to rotate in different directions. This multi-functionality reduces the need for separate dedicated components, thereby managing device complexity while achieving multiple objectives.
