Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large infrared window on remote control devices, made of translucent material, exposes internal circuit members, compromising the device's aesthetics and functionality.
Innovation Solution
A remote control device design featuring a first and second housing with Light Emitting Diodes (LEDs) for infrared light transmission, where a window and window button made of infrared-transmitting material cover and expose parts of the circuits, allowing for adjustable exposure of the internal components to enhance infrared transmission and maintain aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large infrared window is used to expand the infrared transmission area, then the infrared transmission area is improved, but the internal circuit members are exposed which spoils the beauty of the remote control device
Solution Approach 1:
The infrared window is divided into multiple segments (first infrared window and second infrared window) that can be selectively positioned or covered. This segmentation allows the device to provide large infrared transmission area when needed while being able to cover or segment the window area to maintain aesthetic appearance when infrared transmission is not the primary function.
Solution Approach 2:
The remote control device incorporates a movable cover or adjustable mechanism that can dynamically cover or expose the infrared window. This dynamic capability allows the device to switch between providing maximum infrared transmission area and maintaining aesthetic appearance by covering the window with a matching panel or bezel when not in use.
2Reliability
If a translucent material is used for the infrared window to transmit infrared light, then the infrared transmission function is improved, but the internal circuit members become visible which compromises the device's aesthetics
Solution Approach 1:
The window material is designed with specific local properties - it is made translucent or transparent specifically in the regions where infrared transmission is required, while other parts of the device housing maintain opaque, aesthetically pleasing materials. This local quality differentiation allows infrared transmission function to be preserved in specific areas without compromising the overall aesthetic appearance of the device.
Solution Approach 2:
A cover panel or bezel acts as an intermediary element that can cover the translucent infrared window when aesthetic appearance is prioritized. This intermediary component allows the device to switch between functional mode (window exposed for infrared transmission) and aesthetic mode (window covered to hide internal circuit members), resolving the contradiction between function and appearance.
3Adaptability or versatility
If multiple infrared transmission units are included to control multiple external devices, then the control versatility is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The remote control device is designed with multiple infrared transmission units that can be selectively activated or positioned. Each unit serves as a universal infrared transmitter capable of controlling different types of external devices. This multi-functionality approach allows a single device to control multiple devices without requiring completely separate specialized transmitters for each function, thereby improving versatility while managing manufacturing complexity through standardized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design expands the infrared transmission area while maintaining the device's appearance by integrating the window button with the battery-receiving space, allowing for adjustable exposure of internal components, thus addressing the aesthetic and functional issues.
