Remote Control Random Addressing for UHF Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices using ultra-high frequency signals face issues with unintentional control of multiple devices due to limited address options, leading to potential conflicts and difficulties in manually modifying addresses to resolve these conflicts.
Innovation Solution
A remote control device generates a random number as a unique address, which is stored and included in commands transmitted to an electronic device, allowing for secure and flexible communication by distinguishing itself from other devices and enabling users to generate or set new addresses to resolve conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a digital address value is preset at the factory to identify the remote control, then one remote control can be distinguished from another, but the odds of two remotes having the same address become significant when only a few distinct addresses are available
Solution Approach 1:
The patent changes the parameter of address generation from fixed factory presets to dynamically generated random values. This allows the addressing system to utilize the full range of possible digital values, dramatically increasing the addressing capacity and reducing collision probability while maintaining reliable device identification.
Solution Approach 2:
The patent introduces dynamic address assignment where each remote control generates its own unique address randomly rather than using a static factory-preset address. This dynamic approach ensures that addresses are distributed across the entire available range, maximizing versatility while maintaining identification reliability.
2Ease of operation
If manual modification of remote control address is allowed to solve addressing conflicts, then address conflicts can be resolved, but detecting such conflicts becomes difficult and mistakes in modifying address values may occur
Solution Approach 1:
The patent implements self-service addressing where each remote control autonomously generates its own unique address through random number generation. This eliminates the need for manual address modification and conflict detection, as the system automatically ensures unique identification without user intervention or potential for human error.
3Adaptability or versatility
If UHF signals are used to transmit commands, then the remote control device and the product to be controlled are allowed to be located in separate rooms, but the remote control device may unintentionally alter the operation of another product within range
Solution Approach 1:
The patent applies local quality by associating each command with a specific remote control's unique randomly generated address. This allows UHF signals to propagate freely across rooms while ensuring that only the intended electronic product (which recognizes its paired remote's address) executes the command, preventing unintentional control of other devices.

AI summary
A remote control device is presented which includes a user interface, control logic, a memory and a transmitter. The user interface is configured to accept an input from a user. The control logic is configured to generate a random number as an address for the remote control device, and to generate a command for an electronic device based on the input from the user. The command comprises the address. The memory is configured to store the address for the remote control device. The transmitter is configured to transmit the command to the electronic device.
