Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices require multiple setups and KVM switches to share between multiple computer systems, leading to cluttered workspaces and noticeable switching delays, especially in environments needing real-time multi-screen viewing.
Innovation Solution
An input device with a radio transceiver and controller that switches operating channels between first and second computer systems in response to specific events, eliminating the need for KVM switches and reducing switching delays by directly communicating with both systems via wireless communication technologies like Bluetooth or ZigBee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input devices are connected to each computer system, then each computer system can be used independently, but the workspace becomes cluttered and management becomes complex
Solution Approach 1:
The input device is designed to function with multiple computer systems through a single device. The radio transceiver can operate on different frequency channels, allowing the input device to communicate with either the first or second computer system as needed, eliminating the need for separate input devices for each system.
Solution Approach 2:
A KVM switch is introduced as an intermediary device to manage connections between the input device and multiple computer systems. The KVM switch routes signals between the input device and the appropriate computer system based on switching commands, allowing single input device to control multiple systems without workspace clutter.
2Adaptability or versatility
If a KVM switch is used to share input devices between multiple computer systems, then device sharing is enabled, but switching delays occur that affect real-time operations
Solution Approach 1:
The input device proactively monitors for switching events and pre-prepares for channel changes. When a switching event is detected (such as a specific key combination or signal), the radio transceiver quickly transitions to the appropriate frequency channel before the user needs to interact with the system, minimizing perceptible delay.
Solution Approach 2:
The radio transceiver dynamically switches operating channels in response to detected switching events. The system transitions from static channel assignment to dynamic channel switching, allowing the input device to adapt its communication frequency in real-time based on which computer system should receive input signals.
3Productivity
If the radio transceiver switches operating channels in response to events, then seamless switching between systems is achieved, but the switching logic complexity increases
Solution Approach 1:
The input device autonomously monitors for switching events and performs channel switching without requiring external KVM switch intervention. The controller detects predefined events (such as specific key combinations, button presses, or signal patterns) and automatically transitions the radio transceiver to the appropriate channel, making the system self-managing and reducing external complexity.

AI summary
An input device for switchable use between first and second computer systems. A controller of the input device can execute switching logic to direct a radio transceiver of the input device to switch an operating channel of the radio transceiver to a first channel monitored by the first computer system in response to a first event, and thereby, the input device can be utilized to insert data into the first computer system. The controller can execute switching logic to direct the radio transceiver to switch the operating channel to a second channel monitored by the second computer system in response to a second event, and thereby, the input device can be utilized to insert data into the second computer system.
