Remote Control Wheel Button Buffer for Fast Channel Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control devices with wheel buttons experience issues in matching user intentions with control signals, leading to slow channel switching and unintended channel changes due to inconsistent output of control signals.
Innovation Solution
A remote control device with a user input interface, memory, and processor that generates and outputs wheel input control signals, stores repeat signals in a key buffer, and deletes them when the input is no longer continuous, ensuring consistent and natural signal output similar to hard keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the wheel button is used to change channels, then the user can control the TV, but the channel switching is slow compared to hard keys
Solution Approach 1:
The system performs preliminary actions by storing control signals in a buffer before they are executed. When the wheel button is pressed, the control signal is generated and stored in advance, allowing for smoother and faster channel switching by preparing the signal transmission sequence.
Solution Approach 2:
The system dynamically adjusts the control signal output based on the continuous input detection from the wheel button. By using a buffer to hold multiple control signals and releasing them sequentially, the system creates a dynamic response that adapts to the user's input duration, making the wheel button as responsive as hard keys.
2Productivity
If the wheel button input is continuously detected, then repeat control signals can be generated, but control signals are output even after the user stops using the wheel button
Solution Approach 1:
The system uses feedback by continuously detecting whether the wheel button input is still being held. The buffer only releases control signals as long as the continuous input condition is met, and stops releasing signals when the user releases the button, preventing unintended channel changes and improving control accuracy.
Solution Approach 2:
The system implements periodic detection of the wheel button input state to determine whether to continue generating repeat control signals. By checking the continuous input condition at regular intervals, the system ensures that control signals are only output during the intended operation period, maintaining both productivity and reliability.
3Ease of operation
If the wheel button control signal output is made similar to hard keys, then user experience improves, but the system complexity increases due to buffer management
Solution Approach 1:
The buffer mechanism serves multiple functions: it stores control signals for delayed execution, manages repeat signal generation, and controls signal release based on continuous input detection. This multi-functionality allows the wheel button to behave similarly to hard keys while consolidating the complexity into a single versatile component.
