Backup Remote Control Identifier Assignment via Power Cycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing a wireless remote control in installations with multiple roller shutters connected to the same circuit breaker are inefficient, as cutting the power supply to all shutters to reassign identifiers results in all shutters changing identifiers, leading to incorrect assignment and operational issues.
Innovation Solution
A method involving a controlled power cutoff and restoration to the group of receivers, allowing each to memorize a new identifier while keeping the old one in memory, ensuring only the intended shutter receives the old identifier and updates to the new one, with a confirmation code process for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power supply is cut to the group of receivers to reassign identifiers, then all receivers are placed in identifier acquisition mode, but all shutters change identifiers causing incorrect assignment
Solution Approach 1:
The system performs preliminary actions by storing the old identifier in an annexed memory before completely overwriting it with the new identifier. This preliminary preservation allows the system to later verify which shutter should retain the old identifier, preventing incorrect assignment while maintaining the simplicity of power-cut-based reassignment.
Solution Approach 2:
The system uses feedback mechanisms where receivers monitor incoming identifiers and compare them against stored old identifiers. When a receiver detects the old identifier again (from its originally paired remote), it knows to delete the new identifier and keep the old one, ensuring correct identifier assignment based on feedback from the communication pattern.
2Ease of operation
If a button on the receiver is used to place it in recording mode, then identifier replacement is simple, but access to the command button becomes difficult
Solution Approach 1:
The invention replaces the mechanical button-pressing method with an electrical power control method. Instead of requiring physical access to press a button on the receiver, the system uses a circuit breaker or switch to cut and restore power supply, which automatically triggers identifier acquisition mode in all receivers. This substitutes a mechanical interaction with an electrical control mechanism that is easier to access.
3Adaptability or versatility
If power is cut via circuit breaker to reset identifiers, then remote control replacement is enabled, but all roller shutters in the powered group change identifiers
Solution Approach 1:
Before the new identifier completely replaces the old one, the system performs a preliminary action of storing the old identifier in an annexed memory. This allows the system to later distinguish which shutter should keep the old identifier (the one that receives it again from its original remote) and which should adopt the new identifier, ensuring identifier consistency while enabling remote replacement.
Solution Approach 2:
The system establishes a feedback loop where receivers continuously monitor incoming identifiers. When a receiver detects the old identifier again (transmitted by its originally paired remote control), it uses this feedback to determine that it should retain the old identifier and delete the new one, while other receivers that don't receive the old identifier again will keep the new identifier.

AI summary
The method involves placing a group of receivers in storage mode for allowing the acquisition of a new identifier of a new wireless control. The new control is actuated for emitting the new identifier. The new identifier is stored by each receiver in the group while conserving a preceding identifier in an additional memory. The new identifier stored in the receiver is erased and the preceding identifier is conserved when the new identifier received by the receiver corresponds to the preceding identifier.
