Remote Control Protector for IR Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls experience communication errors due to interference from environmental infrared (IR) signals, such as those emitted by the sun and other objects, which can attenuate IR signal performance and cause interruptions.
Innovation Solution
A remote control protector with a body and a shelter that houses the remote control, featuring openings to expose the transceiver while a surrounding shelter blocks environmental IRs, minimizing interference and enhancing signal accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transceiver is fully exposed to receive IR signals, then the signal reception capability is improved, but the transceiver becomes vulnerable to environmental IR interference
Solution Approach 1:
The patent applies local quality by creating a shelter structure that selectively covers specific areas around the transceiver. The shelter provides IR protection in directions where environmental interference originates (such as from the sun or surrounding objects) while leaving the front-facing opening exposed to receive remote control signals. This localized protection approach ensures that only necessary areas are shielded, maintaining signal reception capability while reducing harmful environmental interference.
2Object-affected harmful factors
If the transceiver is fully enclosed to block environmental IRs, then the anti-interference capability is improved, but the signal reception capability deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the shelter into multiple sections: a front opening that remains exposed for receiving IR signals from remote controls, and surrounding shelter portions that extend to block environmental IR interference from other directions. The shelter may include side walls, rear portions, or directional shields that segment the protection coverage. This segmented approach ensures that the transceiver receives necessary signals while being protected from harmful environmental sources.
3Ease of operation
If the remote control is used under direct sunlight, then the ease of operation is improved, but the communication error rate increases due to IR interference
Solution Approach 1:
The patent applies preliminary anti-action by implementing the shelter structure in advance, before environmental IR interference can affect the transceiver. The shelter is pre-configured to block sunlight and other environmental IR sources from reaching the transceiver, thereby preventing communication errors before they occur. This allows the remote control to be used effectively under sunlight conditions without requiring additional protective measures during operation.
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
The remote control protector effectively reduces communication interruptions from environmental IRs, thereby increasing the accuracy and transmission distance of IR signals received by the transceiver.
Implementation Method 1
The shelter extends from the second surface of the body along an axial direction of the body, surrounds the second surface, and has an outlet opening communicating with the second opening of the second surface... to block the environmental IRs so as to prevent the interruption from the environmental IRs

AI summary
A remote control protector for anti-light interference includes a body and a shelter. The body includes a housing space, a first surface, and a second surface. The housing space is for disposing a remote control. The first surface includes a first opening communicating with the housing space. The second surface includes a second opening communicating with the housing space and the second opening is adapted to expose a transceiver of the remote control. The shelter extends from the second surface of the body along an axial direction of the body, surrounds the second surface, and has an outlet opening communicating with the second opening of the second surface.
