Wireless Motor Switching Setup for Remote End-Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing switching devices for electric motors require manual operation and two technicians to set up, which is time-consuming and inefficient, especially when installed in hard-to-reach locations like greenhouses.
Innovation Solution
A switching device with a control unit connected to wireless communication means that allows for remote operation, enabling a single technician to store end positions and control the motor without physical access, using wireless communication or a user interface for setup and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual operation and two technicians are used for setup, then the switching device can be configured accurately, but the setup time and man-hours increase significantly
Solution Approach 1:
The patent replaces the mechanical/manual setup process with a wireless communication system. The control unit receives wireless signals containing position information and automatically stores end positions in memory, eliminating the need for manual operation and reducing setup time while maintaining accuracy through automated position detection and storage
Solution Approach 2:
The switching device performs self-configuration by automatically detecting motor position through the position sensor and storing end positions in its own memory when receiving wireless commands. The device serves itself by autonomously completing the setup process without requiring external manual intervention, thereby reducing setup time and man-hours
2Productivity
If the switching device is installed in hard-to-reach locations, then the motor control is optimized, but the setup process becomes more difficult and time-consuming
Solution Approach 1:
The patent introduces wireless communication as an intermediary between the technician and the switching device. The wireless signal transmission allows setup operations to be performed remotely without requiring physical access to the device location, making installation in hard-to-reach places convenient while maintaining full setup functionality
Solution Approach 2:
The patent replaces the mechanical requirement of physical access to the switching device with wireless communication. Instead of needing to physically reach the device to input data or configure settings, the system uses wireless signal transmission to convey position information and configure the device remotely, thereby improving ease of operation for remote installations

AI summary
A switching device for switching an electric motor includes a control unit configured to provide a first switching signal for the electric motor, a memory configured to store at least one end position, and a position sensor configured to provide the control unit with an electrical position signal which indicates a measured position. The control unit is connected communicatively to wireless communication means and is configured to store the measured position in the memory as said at least one end position on the basis of the position signal in response to a received first instruction. The control unit is configured to provide the first switching signal by comparing the stored end position and a position signal measured by the position sensor. A drive with such a switching device and a method for setting up such a switching device.
