Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching between multiple computing devices with wireless keyboards, as existing solutions require cumbersome re-pairing processes and increased power consumption for each device change.
Innovation Solution
A multi-host wireless input device with a housing and communications module that allows for simultaneous pairing with multiple computing devices, using light-emitting members to indicate connections and store pairings for seamless switching without re-pairing, reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless keyboard connects to multiple computing devices simultaneously, then switching between devices becomes easier, but power consumption increases
Solution Approach 1:
The patent segments the connection management by providing separate host connection keys (first host connection key, second host connection key) for different computing devices. Each key independently controls connection to a specific host, allowing the keyboard to maintain multiple simultaneous connections without requiring full re-pairing when switching. This segmentation enables easy switching while managing power consumption by maintaining connections only when needed.
Solution Approach 2:
The patent implements preliminary pairing where the keyboard pre-establishes connections with multiple computing devices before actual use. The pairing information is stored in the keyboard's memory, so when switching between devices, the connection is restored immediately without requiring re-discovery or re-pairing. This preliminary action resolves the contradiction by making switching trivial while avoiding continuous high power consumption.
2Loss of time
If wireless keyboard maintains connection to multiple devices, then re-pairing process is eliminated, but device complexity increases
Solution Approach 1:
The patent divides connection management into separate, dedicated host connection keys for different computing devices. Each key is associated with a specific host through indicator lights, creating a simple one-to-one mapping that users can easily understand and operate. This segmentation approach eliminates the need for complex connection management while maintaining multiple simultaneous connections.
Solution Approach 2:
The patent incorporates indicator lights that provide visual feedback about the current connection state. Each host connection key has an associated indicator light that illuminates to show which device is currently connected or available. This feedback mechanism simplifies the user interface by providing clear, intuitive status information without requiring complex menus or settings, thus reducing perceived device complexity while enabling multi-device connectivity.
