Remote Controller Custom Code Switching for Adjacent Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls using fixed custom codes for devices of the same manufacturer often unintentionally control multiple devices simultaneously due to proximity, leading to malfunctions and interference.
Innovation Solution
A system that adapts custom codes by recognizing adjacent devices, allowing separate control by changing custom codes based on device information, either through manual selection or automatic network-based settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed custom code is used for remote control, then device compatibility and ease of operation are improved, but unintended simultaneous control of multiple devices occurs
Solution Approach 1:
The patent applies dynamics by making the custom code changeable rather than fixed. The system dynamically adjusts the custom code based on the detected number of adjacent devices, transitioning from a static code to an adaptive code that responds to environmental conditions. This resolves the contradiction by maintaining ease of operation through automated adaptation while improving reliability by preventing unintended device control.
Solution Approach 2:
The patent changes the parameter of the custom code itself, modifying it based on the number of detected devices. When multiple devices are detected, the system alters the custom code parameter to ensure unique identification. This parameter change strategy maintains operational simplicity while eliminating the reliability issue of accidental simultaneous device control.
2Ease of manufacture
If the same custom code is used across devices of the same manufacturer, then manufacturing simplicity and ease of manufacture are improved, but device interference and malfunction occur
Solution Approach 1:
The patent applies segmentation by dividing the device group into individually identifiable units. Each device receives a unique custom code based on its position or detection order among adjacent devices. This segmentation strategy maintains manufacturing simplicity through automated code assignment while eliminating device interference by ensuring code uniqueness.
Solution Approach 2:
The patent implements local quality by assigning different custom codes to different devices based on their local environment and detected device count. Each device's custom code is optimized for its specific context rather than using a universal code. This approach maintains ease of manufacture through systematic code generation while preventing harmful interference between devices.
3Area of stationary object
If multiple devices are placed in close proximity, then space utilization is improved, but remote control reliability deteriorates due to simultaneous device response
Solution Approach 1:
The patent applies dynamics by making the custom code adaptive to the number of adjacent devices. When devices are placed in close proximity, the system detects the increased device count and dynamically adjusts each device's custom code to ensure unique identification. This maintains space utilization efficiency while restoring remote control reliability in dense device environments.
