Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of functions in household display devices complicates remote control design, making it difficult to reduce the size of the remote control and burdens users with numerous buttons.
Innovation Solution
A display system with a remote control featuring illuminated buttons that switch between illuminating and non-illuminating states, allowing different operations based on their state, enabling reduced button count and simplified user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of functions in household display devices is increased, then the functionality and versatility of the display device is improved, but the number of buttons on the remote control must be increased, making the remote control larger and more burdensome for users
Solution Approach 1:
The patent applies multi-functionality by enabling a single button to perform multiple functions based on its illumination state. The same physical button can execute different commands when illuminated versus non-illuminated, allowing one button to replace what would traditionally require multiple separate buttons, thus reducing the overall button count while maintaining comprehensive functionality
Solution Approach 2:
The patent utilizes parameter changes by altering the illumination state of the button to differentiate between functions. By changing the optical parameter (illuminated vs. non-illuminated state), the system enables a single button to trigger different operations, effectively using state change to expand functional capability without adding physical components
2Adaptability or versatility
If the number of buttons on the remote control is increased to match more functions, then the functionality is improved, but the physical size of the remote control increases
Solution Approach 1:
The patent implements multi-functionality where a single button serves multiple purposes through state differentiation. By making the button's illumination state part of its functional identity, the system reduces the total number of buttons needed, thereby decreasing the remote control's physical footprint while maintaining comprehensive functionality
Solution Approach 2:
The patent merges multiple functional buttons into a single physical button by using illumination state as a differentiator. Instead of having separate buttons for different functions, the system combines them into one button that changes its functional identity through illumination, effectively merging multiple controls into a single compact element
3Adaptability or versatility
If multiple buttons are added to the remote control to provide more functions, then the versatility is improved, but the ease of operation decreases due to the burden of numerous buttons
Solution Approach 1:
The patent applies multi-functionality to reduce the number of buttons users must navigate. By making a single button universal through illumination-based function differentiation, the system simplifies the user interface and reduces the cognitive and physical burden of selecting from multiple buttons, thereby improving ease of operation while maintaining versatility
Solution Approach 2:
The patent uses illumination (light emission) as a visual indicator to differentiate button functions. The illuminated state provides visual feedback that distinguishes different functional modes, making the interface more intuitive and easier to operate by clearly indicating which function is active without requiring users to remember or count multiple buttons

AI summary
A display system includes a display that includes a display processing unit, and a remote control (RC) that includes an RC processing unit and an illuminated button. The illuminated button is configured to switch between an illuminating state and a non-illuminating state, output a first operating signal upon being pressed when in the non-illuminating state, and output a second operating signal upon being pressed when in the illuminating state. The RC processing unit is configured to transmit a first command signal that corresponds to the first operating signal, and transmit a second command signal that corresponds to the second operating signal. The display processing unit is configured to execute a first operation based on the first command signal, and to execute a second operation based on the second command signal.
