Optoelectronic Sensor Parameterization via Image Code Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optoelectronic devices require complex and labor-intensive parameterization processes, often involving multiple rotary switches and manual input devices, which are cumbersome and inefficient, especially in spatially restricted applications and when dealing with multiple parameter codes.
Innovation Solution
A parameter presentation unit that allows for the easy and automatic reading of individual parameter codes by the image sensor, eliminating the need for separate parameterization devices and reducing design effort, by using a mechanical unit with a code carrier and template to selectively display and read parameter codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple rotary switches are provided for parameterization, then IP address assignment is possible, but design effort increases undesirably
Solution Approach 1:
The patent combines multiple parameter input functions into a single rotary switch. Instead of requiring separate rotary switches for each parameter (IP address, subnet mask, gateway), one multifunctional rotary switch handles all parameter inputs by cycling through different parameter modes, thereby reducing component count while maintaining full parameterization capability
Solution Approach 2:
The rotary switch is designed with universal functionality to handle multiple parameterization tasks. By implementing different operating modes within a single switch, it can assign IP addresses, configure network parameters, and perform other setup functions, making the device adaptable to various parameterization needs without requiring dedicated controls for each function
2Ease of operation
If setting devices with displays and keys are used for parameterization, then parameter input is possible, but design effort increases
Solution Approach 1:
The patent replaces complex mechanical input devices (displays, buttons, keyboards) with a simplified rotary switch mechanism. This mechanical substitution reduces the complexity of the parameterization device while maintaining ease of use, as the rotary switch provides intuitive control without requiring additional display screens or multiple input keys
Solution Approach 2:
The rotary switch system is designed to be self-sufficient for parameterization tasks. It integrates all necessary control functions within the single switch mechanism, eliminating the need for separate display units, keypads, or additional input devices. The system serves itself by combining selection, input, and confirmation functions into one unified control element
3Quantity of substance
If parameter codes are printed side by side in manuals, then multiple parameter codes are available, but individual code reading becomes impossible
Solution Approach 1:
The patent extracts individual parameter codes from the crowded manual layout and presents them one at a time through the rotary switch interface. By cycling through codes sequentially and displaying only the current active code, the system allows selective reading of individual parameter codes without the confusion of having all codes visible simultaneously, thus maintaining code availability while enabling precise selection
