Awning Motor Control With Integrated Radio Receiver Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing awnings with electric motor-driven roller tubes require multiple radio receivers due to interference, leading to increased cabling effort and costs, and pose risks of incorrect operation and damage during retraction.
Innovation Solution
An integrated control device that processes radio remote control signals to control the electric drive motor and additional supply lines, such as lighting or heating, reducing wiring needs and ensuring safe operation by prioritizing motor activation and monitoring power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio receivers are assigned to each electrical device, then each device can be controlled independently, but the cabling effort and costs increase significantly
Solution Approach 1:
The patent combines multiple radio receiver functions into a single centralized control device. Instead of having separate radio receivers in each electrical device (lighting, heating, awning motor), all devices are controlled through one control device that receives and processes radio remote control signals. This merging eliminates the need for multiple receivers and reduces cabling complexity while maintaining full control capability over all devices.
Solution Approach 2:
The control device is designed as a universal controller that can manage multiple different electrical devices through a single interface. It provides multi-functionality by controlling the awning motor, lighting, heating, and potentially other devices through one unified radio receiver and control unit, eliminating the need for device-specific receivers and reducing overall system complexity.
2Ease of operation
If multiple radio receivers are installed to control different devices, then each device can be operated independently, but the installation costs and wiring requirements increase
Solution Approach 1:
The patent merges the control functions for multiple devices into a single control device, eliminating the need for separate receivers in each device. This reduces installation costs and wiring requirements while maintaining the ability to independently control each device through the centralized controller's processing capabilities.
Solution Approach 2:
The centralized control device acts as an intermediary between the radio remote control and multiple electrical devices. It receives radio signals, processes the control commands, and activates the appropriate devices, thereby maintaining independent device control capability while simplifying the physical installation and reducing costs.
3Area of stationary object
If radio receivers are placed close together for compact installation, then installation space is reduced, but the receivers interfere with each other and cannot function properly
Solution Approach 1:
The patent eliminates the interference problem by combining multiple receiver functions into a single radio receiver located in the control device. This allows compact installation without receivers being placed close together, as there is only one receiver. The single receiver processes all control signals for different devices, maintaining reliable operation while enabling compact installation space.
