Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional I/O devices in automation control systems face inefficiencies due to obscured address labels on terminal blocks, making it difficult to interpret status indicators and diagnose issues effectively.
Innovation Solution
The alignment of status indicators directly adjacent to or integrated within the terminals on the terminal block, utilizing light emitters and light pipes to illuminate indicators based on input and output signals, providing clear and direct visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If status indicators are located on the status display of the I/O module, then users can observe the status of the automation control system, but the address labels become obscured by wiring making it difficult to correlate indicators with terminals
Solution Approach 1:
The patent moves status indicators from the I/O module to the terminal block itself, changing the spatial dimension of indicator placement. Each indicator is positioned directly adjacent to its corresponding terminal, eliminating the need to cross-reference between separate locations and removing wiring obstruction issues.
Solution Approach 2:
The patent creates a visual copy of the terminal arrangement on the terminal block face, with each status indicator positioned to directly correspond to its associated terminal. This spatial copying allows operators to see both the terminal and its status indicator in the same field of view, eliminating correlation difficulties.
2Loss of information
If address labels are used to correlate indicators with terminals, then users can identify correspondences, but the labels become obscured by wiring reducing readability
Solution Approach 1:
The patent extracts the status indication function from the I/O module and relocates it directly to the terminal block. By placing indicators adjacent to their corresponding terminals, the system eliminates the need for separate address labels, as the spatial relationship itself provides the correlation information.
Solution Approach 2:
The patent uses illuminated status indicators with distinct colors (such as green, yellow, red) to indicate different terminal states. These self-luminous indicators provide clear visual differentiation without requiring external labels, making status visible regardless of wiring obstruction.
3Device complexity
If traditional status display location is used on the I/O module, then the device structure remains simple, but diagnostic efficiency is reduced due to obscured labels
Solution Approach 1:
The patent relocates status indicators to the terminal block face, utilizing the two-dimensional surface area of the terminal block rather than placing indicators on the I/O module. This spatial redistribution improves diagnostic efficiency by making indicators and terminals co-located, without significantly increasing overall device complexity.

AI summary
Systems and methods are provided for aligning status indicators on a terminal block of an I/O device by locating the status indicators directly adjacent to or integrated directly within their respective terminals on the terminal block. The status indicators are illuminated by LEDs or other light emitters disposed within a housing of the terminal block. Light from the LEDs are directed to the status indicators by light pipes disposed within the housing of the terminal block. LED activation circuitry disposed within the housing determines a manner in which to activate the LEDs to illuminate the status indicators based on input and outputs between the I/O device and a controlled process. In certain embodiments, the status indicators are disposed on a raised section of the terminal block from a front face of the terminal block, which may be part of a removable LED indication assembly including the LEDs, light pipes, and LED activation circuitry.
