Slave Device Wireless Reconfiguration via Discover Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems face challenges in reconfiguring slave devices to be controlled by new or replacement remote controllers, especially when the original controller is damaged or unavailable, and when slave devices are not easily accessible, making it impractical to reconfigure multiple devices within the required time frame.
Innovation Solution
A method that allows a new remote controller to configure slave devices by using previously stored reconfiguration data, such as a system ID and password, which is user-defined and transmitted wirelessly, enabling the slave devices to enter a discover mode and re-establish secure communication, even when the original remote controller is not accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a special procedure is used to reset or erase storage means in the slave device (e.g., by activating an operation button under a top cover), then the slave device can be reconfigured to work with a new remote controller, but the reconfiguration process becomes highly impractical when the slave device is not readily accessible (e.g., connected to a roof window under the ceiling)
Solution Approach 1:
The patent replaces the mechanical operation of physically accessing and manipulating buttons on slave devices with a wireless electronic system. The master unit transmits reconfiguration commands wirelessly to slave devices, eliminating the need for physical access to device buttons or covers. This substitution resolves the contradiction by maintaining reconfiguration capability while removing the accessibility requirement.
2Adaptability or versatility
If multiple slave devices need to be reconfigured, then complete system reconfiguration is possible, but the time required becomes overwhelming or impossible if manual access to each device is required
Solution Approach 1:
The patent merges the reconfiguration process into a single unified operation initiated from the master unit. Instead of requiring separate manual access to each slave device, the master unit transmits reconfiguration commands to multiple slave devices simultaneously or sequentially in an automated manner. This consolidation reduces the total reconfiguration time from an overwhelming duration to a manageable process, resolving the time loss contradiction while maintaining complete system reconfiguration capability.
3Reliability
If the original remote controller is damaged or unavailable, then system security is compromised, but without access to the original controller, reconfiguration becomes impossible using traditional methods
Solution Approach 1:
The patent introduces a wireless command transmission system as an intermediary between the user and slave devices. When the original remote controller is unavailable, the master unit serves as a mediator that can initiate reconfiguration sequences and transmit new control codes to slave devices without requiring physical access or the original controller. This intermediary mechanism restores both system availability and reconfiguration accessibility, resolving the contradiction.

AI summary
A method of enabling a slave device to enter a discover mode, said slave device (2) having been configured to be controllable by at least one remote controller (4) at a previous configuration step, whereby said slave device (2) has been paired with said at least one remote controller (4) to be controllable by said at least one remote controller, said method comprising that - reconfiguration data RD has been stored by said slave device (2); - at least part of said reconfiguration data RD is received by said slave device (2), - said slave device (2) when having received said at least part of said reconfiguration data (RD) and verified correspondence with stored data, enters said discover mode, and - whereby a re-configuration of said slave device is enabled in dependence on further communication with a further remote controller (6), from which said at least part of said reconfiguration data (RD) has been transmitted.
