Rollable Keyboard with Magnetic Secure Rolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable keyboards are bulky, inconvenient to carry, and difficult to set up due to their wired connections and lack of foldability, making them unsuitable for portable use with multimedia devices.
Innovation Solution
A portable keyboard designed to roll up like a scroll, featuring a polygonal shape with a capacitive or pressure-sensitive key assembly, magnetic elements for secure rolling, and a setup part with rotary members for easy deployment and connection to mobile terminals, enabling wireless communication and stereo sound output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional portable keyboards are made foldable or rollable, then portability is improved, but structural complexity increases
Solution Approach 1:
The patent applies this principle by using a flexible connecting member that allows the key assembly to be rolled up around the main body. The flexible nature of this connecting component enables the keyboard to transition from a flat expanded state to a compact rolled state without requiring complex mechanical joints or hinges, thus achieving portability improvement with minimal structural complexity increase.
2Ease of operation
If wireless communication is added to portable keyboards, then ease of setup is improved, but device complexity increases
Solution Approach 1:
The patent applies this principle by replacing the mechanical wired connection system with a wireless communication system. Instead of requiring physical cable connections for setup, the keyboard uses wireless communication modules to establish connections with mobile terminals, thereby improving ease of setup while the modular design keeps the added complexity manageable.
3Reliability
If magnetic elements are added for secure rolling, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies this principle by using magnetic elements that automatically attract and hold the rolled-up key assembly against the main body without requiring manual fastening mechanisms. The magnetic force self-regulates to maintain the rolled state, providing reliable secure rolling while adding minimal structural complexity compared to mechanical fasteners or clips.
