Signaling Device Analog Range Selection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Signaling devices in industrial environments face challenges with limited space for operating elements due to narrow housings, leading to potential misconfiguration and unreliable measured values due to mechanical tolerances between analog setting elements and measuring-range displays.
Innovation Solution
A signaling device with a range scale featuring alternating setting and transition ranges, where the analog selection device captures and checks selection values to output signals indicating transition ranges, ensuring unambiguous selection and improved reliability through additional feedback mechanisms like LEDs or vibrators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the housing is made narrow to reduce space occupation, then the housing width is reduced, but the space for operating elements becomes insufficient
Solution Approach 1:
The patent introduces a new dimension of information display by adding a visual indicator system (LEDs or other visual signals) that provides range selection feedback without requiring additional mechanical space. This allows the operating elements to remain compact while maintaining ease of operation through visual confirmation.
2Manufacturing precision
If mechanical tolerances are reduced to improve setting precision, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical indication system with an electronic/visual indication system. Instead of relying solely on precise mechanical alignment between the analog selection device and the scale markings, the system uses visual indicators (such as LEDs) to clearly indicate the selected range, thereby eliminating the need for tight mechanical tolerances.
Solution Approach 2:
The patent implements a feedback mechanism where the signaler provides visual confirmation of the selected range. This feedback loop allows the user to verify the selection independently of mechanical precision, as the visual indicator clearly shows which range is active, compensating for any mechanical tolerance issues.
3Length of moving object
If the analog selection device is made smaller to fit narrow housing, then the housing width is reduced, but the reliability of setting values deteriorates
Solution Approach 1:
The patent introduces a signaler that provides visual feedback on the selected range. This feedback mechanism ensures that even when the analog selection device is small and subject to tolerance variations, the actual selected range is clearly indicated, thereby maintaining the reliability of setting values.
Solution Approach 2:
The patent replaces reliance on mechanical precision with an electronic indication system. The signaler provides unambiguous visual confirmation of the selected range, eliminating the need for large, precision-critical mechanical components while maintaining setting reliability.

AI summary
A signaling device which generates a selection signal via an analog selection device for choosing a signal range, and a range scale for displaying the signal range chosen by the analog selection device, wherein the range scale includes setting ranges and a transition range, where one setting range of the setting ranges is arranged in an alternating manner with the transition range along the range scale, and the analog selection device is arranged such that selection of a setting range or a transition range along the range scale is selected and the analog selection device defines an analog selection value, and the signaling device additionally detects the analog selection value aided by the selection signal and checks whether this value corresponds to a value allocated to a transition range, and if so, outputs a signal via a signaler.
