Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems do not provide clear indication of their operating mode to users, limiting user awareness and satisfaction, especially in diverse application scenarios where mood and atmosphere creation are desired.
Innovation Solution
A display system comprising a power source unit, signal input unit, video processor, display unit, light-emitting unit with multiple light sources, and a controller that determines the operating mode based on input signals and adjusts power distribution accordingly, using light-emitting patterns to inform users of the mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the display system operates in power-saving mode to minimize power consumption, then power consumption is reduced, but the user cannot clearly know the operating mode
Solution Approach 1:
The patent uses different light-emitting patterns (colors and blinking sequences) of the light source to indicate different operating modes to users. For example, steady light indicates normal mode, blinking light indicates power-saving mode, and continuous illumination indicates driving mode. This allows users to visually perceive the operating mode without increasing power consumption significantly.
2Loss of information
If the display system provides clear indication of operating mode through additional components, then user awareness is improved, but device complexity increases
Solution Approach 1:
The patent makes the existing light source (which is already part of the display system) serve dual purposes: both as a functional component and as an indicator for operating mode. By controlling the light source to emit different patterns based on operating mode, the system avoids adding separate indication components, thus maintaining simplicity while providing clear user feedback.
3Ease of operation
If the display system uses multiple light sources to indicate operating modes, then user experience is enhanced, but power consumption increases
Solution Approach 1:
The patent uses a single light source rather than multiple light sources to indicate operating modes. By controlling the light source to emit different patterns (blinking, steady, continuous illumination) based on the operating mode, the system provides clear user feedback without the additional power consumption that would result from using multiple separate light sources.
