Magnetic Pen Rack for E-Book Charging and Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic book devices face challenges in compactly integrating a magnetic pen and LED light source module without increasing thickness, as well as efficiently charging and powering these components, due to the need for external chargers and compromised aesthetics when attempting to incorporate charging mechanisms.
Innovation Solution
An electronic book device with a magnetic pen rack that includes a leather cover, a rectangular rack with grooves for the magnetic pen and LED light source module, featuring metal contact parts for electrical connection to the electronic book, allowing for compact integration and power supply for charging and illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a charger device is implemented in the electronic book to charge the magnetic pen, then the magnetic pen can be charged conveniently, but the thickness of the electronic book has to be increased
Solution Approach 1:
The charging function is integrated into the side wall of the electronic book rather than adding thickness to the main body. The charging cavity and connector are positioned on the side surface, allowing the magnetic pen to be charged horizontally without increasing the book's thickness in the vertical dimension.
2Ease of operation
If a connector for connecting and charging a magnetic pen is provided on a side wall of the electronic book, then charging is enabled, but the appearance of the electronic book will be compromised and a collision can cause the magnetic pen to fall out
Solution Approach 1:
The magnetic pen is inserted into a recessed charging cavity on the side wall, creating a nested structure where the pen fits within the book's profile. This nesting approach maintains a sleek appearance while enabling charging functionality, and the recessed design prevents the pen from falling out during collisions.
3Adaptability or versatility
If the electronic book thickness is increased to accommodate a charger device, then the magnetic pen can be charged, but the slim outline of the electronic book is lost
Solution Approach 1:
Instead of increasing thickness to accommodate charging functionality, the design utilizes the side wall surface area. The charging cavity and connector are positioned on the lateral surface, transforming the charging function from a vertical integration (increasing thickness) to a horizontal integration (utilizing side surface), thereby preserving the slim outline.
4Ease of operation
If a connector is provided on the side wall for magnetic pen connection, then charging is enabled, but the magnetic pen can easily fall out due to collision
Solution Approach 1:
The magnetic pen connector is positioned within a recessed cavity on the side wall, creating a nested configuration. This recessed structure provides mechanical retention for the pen during charging, preventing it from falling out due to collisions while maintaining reliable electrical connection through the integrated connector.
