Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of functions in household display devices leads to a larger and more complex remote control, making it difficult to reduce size and complicating user operation.
Innovation Solution
A display system with a remote control featuring illuminated buttons that switch between illuminating and non-illuminating states, allowing different functions based on their state, reducing the number of physical buttons needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more functions are added to household display devices, then the functionality and versatility of the device is improved, but the number of buttons on the remote control increases, making it larger and more complex
Solution Approach 1:
The patent applies dynamics by making the button illumination state changeable. Buttons can switch between illuminated and non-illuminated states dynamically, allowing the same physical button to represent different functions at different times. This resolves the contradiction by enabling multiple functions without increasing the number of physical buttons, thus maintaining simplicity while improving versatility.
Solution Approach 2:
The patent changes the parameter of button visibility/illumination to encode different functions. By altering the illumination state parameter of buttons, the system can represent different commands without adding physical buttons. This parameter change allows one button to serve multiple purposes, resolving the contradiction between functionality and device complexity.
2Adaptability or versatility
If more buttons are added to the remote control to accommodate more functions, then the versatility is improved, but the ease of operation deteriorates due to the burden of managing many buttons
Solution Approach 1:
The dynamic illumination state of buttons provides visual feedback that helps users understand which buttons are active and what functions they perform at any given time. This reduces the cognitive burden on users when operating the remote, as they can easily distinguish between different functional states without needing to remember complex button mappings, thus improving ease of operation while maintaining versatility.
Solution Approach 2:
The patent uses illumination (light emission) to indicate different functional states of buttons. By changing the illumination state, the system provides clear visual cues to users about which buttons are active and what they do, making the remote easier to operate. This visual feedback mechanism reduces the complexity of user interaction while preserving full functionality.
3Volume of moving object
If the remote control size is reduced to make it more portable, then the ease of carrying is improved, but the number of available buttons decreases, reducing functionality
Solution Approach 1:
The patent enables a smaller remote control design by making buttons dynamically changeable through illumination states. Instead of needing separate physical buttons for each function, the system uses illumination to differentiate functions on fewer buttons. This resolves the contradiction by allowing the remote to be more compact while maintaining full functionality through state-changing buttons.
Solution Approach 2:
The patent implements multi-functionality where a single physical button can perform multiple functions by changing its illumination state. This universal approach allows fewer buttons to cover more functions, enabling the remote control to be smaller while preserving versatility. The same button serves different purposes at different times, eliminating the need for additional buttons.

AI summary
A display system (1) includes a display (11) that includes a display processing unit (111), and a remote control (RC) (12) that includes an RC processing unit (121) and an illuminated button (123'). The illuminated button (123') 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 (121) 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 (111) 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.
