Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized drive devices for home automation systems for closing or solar protection incur additional costs and product quality risks due to the need for an electronic control card at the autonomous electric power supply device, which also leads to increased energy consumption and battery discharge before commissioning.
Innovation Solution
A control method that activates a selection element during a predetermined period to enter a second standby state with a lower wake-up frequency for the control command reception module, reducing energy consumption and eliminating the need for an electronic control card at the autonomous electric power supply device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an electronic control card is added at the autonomous electric power supply device to inhibit the control command reception module, then energy consumption is reduced and battery discharge is prevented, but device complexity and manufacturing cost increase
Solution Approach 1:
The control card is extracted and removed from the autonomous electric power supply device. Instead of adding complexity at the power supply level, the patent places the control command reception module directly in the actuators, eliminating the need for the electronic control card while maintaining energy savings through software-based inhibition of the reception module.
Solution Approach 2:
The actuator performs the control function itself by integrating the control command reception module directly into it. This self-service approach eliminates the need for separate control cards and allows the actuator to independently manage its own control operations and energy consumption states.
2Loss of energy
If an electronic control card is added at the autonomous electric power supply device, then the control command reception module can be inhibited, but manufacturing cost and product quality risk increase
Solution Approach 1:
The electronic control card is completely extracted from the system architecture. The patent simplifies manufacturing by removing this additional component and its associated assembly steps, while maintaining the ability to prevent battery discharge through software control of the reception module's operational states.
Solution Approach 2:
The control functionality is localized directly to the actuator level rather than being centralized in a separate control card. This local quality approach allows each actuator to independently manage its control operations and energy consumption, simplifying the overall manufacturing process while maintaining effective energy management.
3Speed
If the control command reception module is placed in standby state with frequent wake-up, then responsiveness is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic control of the reception module's operational state. The module can switch between active, standby, and inhibited states based on operational requirements, allowing the system to optimize the balance between responsiveness and energy consumption in real-time without being locked into a fixed state.
Solution Approach 2:
The patent changes the operational parameters of the reception module by introducing multiple distinct states (active, standby, inhibited) with different wake-up frequencies and energy consumption levels. This allows flexible adjustment of the module's behavior to match system requirements, achieving both responsiveness and energy efficiency.

AI summary
A method for controlling the operation of a motorized drive device in a home automation system comprises at least one step (E10) of entering a device configuration mode, a step (E40) of pairing a control point with an electronic control unit of the device, a step (E50) of activating at least one selection element of the control point during a predetermined time period starting after the pairing step (E40), and a step (E80) of entering a second standby state of a command receiving module of the electronic control unit. The second standby state of the command receiving module has a lower wake-up frequency than the wake-up frequency of the command receiving module in the first standby state.
