Motorized Display Cover Control for Noise-Stable Audio Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices expose all regions of the display area regardless of user usage, leading to inefficient space utilization and potential noise and distortion issues when a cover or display moves using a motor.
Innovation Solution
A display device with a motor-controlled cover that selectively exposes a partial or entire display area, accompanied by a controller that adjusts sound output levels and types based on the cover's position and movement to minimize noise and ensure optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor is used to move the cover or display to expose a partial region of the display area, then the display can be selectively exposed to improve space utilization, but noise is generated and sound output distortion occurs
Solution Approach 1:
The controller proactively adjusts the audio output level before the motor completes its movement to expose the partial display region. By detecting the motor's operation and predicting the upcoming state change, the controller preemptively modifies the sound output to compensate for the distortion that will occur when the cover or display reaches its new position, thereby preventing the harmful effect rather than reacting to it afterward
Solution Approach 2:
The system performs the audio level adjustment in advance during the motor's movement process. The controller monitors the motor's operation and adjusts the audio output level during the transition phase, ensuring that by the time the cover or display reaches its final position, the sound output is already optimized and free from distortion
2Adaptability or versatility
If the motor controls the cover to move between fully exposed and partially exposed states, then space utilization improves, but power consumption increases
Solution Approach 1:
The motor operates periodically rather than continuously, moving the cover between fully exposed and partially exposed states based on detected usage patterns. The controller monitors whether the display is actively being used and only activates the motor when a state change is needed, allowing the system to alternate between different exposure states and thereby reducing overall power consumption while maintaining adaptability
Solution Approach 2:
The controller automatically detects the usage state of the display and autonomously controls the motor's operation without requiring manual intervention. By monitoring the display's active state and automatically adjusting the cover position accordingly, the system serves itself by making intelligent decisions about when to move the cover, optimizing both space utilization and energy efficiency
