Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insufficient lighting in the operating environment of notebook computers can lead to poor image quality during online conferences due to inadequate ambient light, affecting the captured person image.
Innovation Solution
An electronic device with an auxiliary lighting function that includes a light-emitting module disposed in the border area of the display screen, activated by a processing module to provide additional illumination when needed, using various types of light-emitting modules such as direct-type, reflective-type, light-guide type, and electroluminescent-type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light-emitting module is added to the border area to provide auxiliary illumination, then image quality in low-light conditions is improved, but device complexity increases
Solution Approach 1:
The light-emitting module is integrated into the existing border area structure of the display screen, merging the lighting function with the structural framework already present in the electronic device. This approach adds illumination capability without requiring a completely separate structural system, thereby improving image quality while limiting the increase in device complexity.
Solution Approach 2:
The border area of the display screen serves dual purposes: it maintains its original structural and aesthetic function while simultaneously housing the light-emitting module to provide auxiliary illumination. This multi-functionality allows the same structural element to contribute to both device integrity and image quality improvement in low-light conditions.
2Illumination intensity
If a light-emitting module is disposed in the border area, then auxiliary lighting is provided for better image capture, but manufacturing complexity increases
Solution Approach 1:
The light-emitting module is pre-integrated into the border area during the manufacturing process, allowing the lighting function to be established before final assembly. This preliminary integration simplifies the overall manufacturing process by avoiding the need for post-assembly installation of lighting components, thereby reducing manufacturing complexity while enabling auxiliary illumination for improved image capture.
3Use of energy by moving object
If the light-emitting module is activated according to required conditions, then energy is saved by not illuminating continuously, but control complexity increases
Solution Approach 1:
The processing module monitors environmental conditions and automatically activates or deactivates the light-emitting module based on detected requirements such as ambient light levels or camera operation status. This feedback-based control system optimizes energy consumption by ensuring the light-emitting module operates only when necessary, while the automation of this control process minimizes the perceived complexity for the user.
