Remote Control Tip Reflector for Wide-Angle IR Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote controls are difficult for individuals with limited mobility due to disease, injury, or aging to operate, especially when requiring three-digit channel number input on devices like televisions, as they need to hold the remote with one hand and view the operation panel with the other, and there is a need for a solution that allows one-handed operation in various positions.
Innovation Solution
A remote control with a reflector at the tip end that controls infrared ray reflection, featuring a front edge, left side edge, and right side edge, allowing operation without aiming at the device, enabling use while lying down or sitting, and improving functionality over multiple infrared light systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple infrared lights are used in the remote control, then the remote control can be operated at various angles and positions, but the device complexity increases
Solution Approach 1:
The reflector is divided into multiple reflective surfaces (first reflective surface, second reflective surface, third reflective surface) that are arranged at different angles. Each surface segment reflects infrared rays in a specific direction, collectively achieving wide-angle coverage without needing multiple infrared light sources. This segmentation of the reflector structure enables versatile operability while maintaining a single infrared light source.
Solution Approach 2:
Instead of adding more infrared lights in the same dimension (increasing quantity), the invention uses a three-dimensional reflector structure with surfaces oriented at different angles (45 degrees, 135 degrees, etc.). This spatial arrangement in multiple dimensions allows infrared rays to be reflected in various directions, achieving wide-angle operability through geometric configuration rather than component multiplication.
2Ease of operation
If the user needs to view the operation panel while operating the remote control, then channel operation can be performed, but the ease of operation decreases for users with limited mobility
Solution Approach 1:
The reflector is designed to dynamically adapt to different operational scenarios by reflecting infrared rays in multiple directions simultaneously. Whether the user is lying on a bed, sitting on a chair, or holding the remote at different angles, the reflector's multi-surface structure ensures that infrared rays are always directed toward the target device, providing dynamic adaptability to various user positions and postures.
Solution Approach 2:
The single reflector structure performs multiple functions: it reflects infrared rays forward, upward, downward, and sideways simultaneously. This multi-functional reflector enables the remote control to be operated from various positions (lying down, sitting, standing) and at various angles, making it universally applicable to different user situations without requiring additional components.
3Ease of operation
If the tip end of the remote control must be aimed at the target device, then the infrared rays are directed accurately, but the ease of operation decreases for users who cannot move their bodies freely
Solution Approach 1:
The reflector acts as an intermediary between the infrared light source and the target device. Instead of requiring direct alignment between the remote control tip and the device, the reflector mediates by receiving infrared rays from the single light source and redirecting them toward the target from multiple angles. This intermediary structure eliminates the need for precise aiming while maintaining effective infrared transmission.
Solution Approach 2:
The reflector changes the directional parameters of infrared rays through its multi-surface geometry. By arranging reflective surfaces at specific angles (45 degrees, 135 degrees, etc.), the reflector transforms the single-directional infrared output into multi-directional radiation patterns. This parameter transformation allows the system to maintain directional accuracy without requiring the user to aim the remote control precisely.
