Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sun screen/shade systems fail to effectively control light intensity and reduce glare on entertainment displays, leading to adverse reflections and reduced image quality, especially in low light conditions.
Innovation Solution
A light control system comprising a computing device, light sensors, and a light damping mechanism, such as a sunshade or electro-chromic filter, that automatically adjusts to reduce light intensity interacting with the display and minimize reflections when the light intensity exceeds a predefined threshold, improving viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the brightness level of the display is increased to overcome light interference, then the display visibility is improved, but the image quality of the video deteriorates
Solution Approach 1:
A light damping mechanism (such as an electrochromic window or sunshade) is introduced as an intermediary between the external light source and the display. This intermediary selectively blocks or dampens harmful light before it reaches the display, eliminating the need to increase display brightness while maintaining image quality. The light damping mechanism acts as a mediator that protects the display from light interference without requiring changes to the display's brightness settings.
Solution Approach 2:
The system applies preliminary anti-action by detecting light conditions in advance and activating the light damping mechanism before light interference adversely affects the display. The control system continuously monitors light intensity and preemptively adjusts the damping mechanism to prevent glare and reflections, thereby maintaining optimal display visibility without compromising image quality.
2Object-affected harmful factors
If a light damping mechanism is activated to reduce light intensity, then glare and reflections are reduced, but the system complexity increases
Solution Approach 1:
The light control system operates autonomously using self-service principles. Light sensors continuously monitor environmental light conditions and automatically trigger the light damping mechanism when thresholds are exceeded. The system serves itself by detecting, deciding, and acting without requiring manual user intervention, thereby reducing the perceived complexity for users while maintaining effective glare control.
Solution Approach 2:
The system implements feedback control by using light sensors to continuously monitor light intensity and feed this information back to the control system. Based on this feedback, the control system automatically adjusts the light damping mechanism to maintain optimal display conditions. This closed-loop feedback system simplifies operation while effectively managing glare and reflections.
3Ease of operation
If manual brightness adjustment is used to improve viewing conditions, then user control is maintained, but the adverse effect of light on display visibility is insufficiently overcome
Solution Approach 1:
The system maintains ease of operation by automatically managing light control without requiring manual brightness adjustments. The self-service light damping mechanism detects and responds to light conditions autonomously, eliminating the need for users to manually adjust brightness settings while effectively overcoming light interference.
Solution Approach 2:
The system changes the parameter of light intensity reaching the display by dynamically adjusting the light damping mechanism based on environmental conditions. This automatic parameter adjustment (light damping) complements or replaces manual brightness control, providing superior protection against light interference while maintaining user convenience.
