Terminal Block Module Door Integrating Attribute Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face poor workability and operability during maintenance and inspection of control systems due to the need for separate lists to identify field device attributes connected to terminal blocks, requiring inefficient reference and verification processes.
Innovation Solution
An electronic device with a terminal block module featuring a door that is openable and closable, allowing for easy access to attribute information display, enabling quick identification of field devices connected to terminals, thereby enhancing workability and operability by integrating the display directly on the terminal block module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If attribute information is displayed on separate lists during maintenance, then information completeness is maintained, but workability and operability deteriorate due to inefficient reference processes
Solution Approach 1:
The patent combines the attribute information display directly with the terminal block module by integrating a display unit into the terminal block housing. This merging eliminates the need for separate lists and allows operators to view attribute information (such as device names, addresses, and connection status) directly at the terminal block location, significantly improving workability and reducing reference time during maintenance and inspection operations.
2Ease of operation
If attribute information is displayed on separate lists, then information organization is maintained, but operability worsens due to requiring separate reference materials
Solution Approach 1:
The patent integrates the display unit, control unit, and attribute information storage into a single terminal block module assembly. This consolidation reduces the number of separate components and materials needed, as operators no longer require separate lists, manuals, or reference documents. The attribute information is now part of the terminal block module itself, simplifying the overall system configuration while maintaining information organization.
3Productivity
If attribute information is integrated into the terminal block module, then workability improves through direct access, but manufacturing complexity increases
Solution Approach 1:
The patent divides the terminal block module into distinct functional segments: the terminal block housing, the display unit, the control unit, and the attribute information storage. This segmentation allows for modular manufacturing where each component can be produced separately and then assembled. The display unit and control unit can be manufactured as separate modules and integrated into the terminal block housing, reducing overall manufacturing complexity while enabling direct access to attribute information during maintenance operations.
Solution Approach 2:
The terminal block module is designed with multi-functionality, serving both as a connection point for field devices and as an information display device. The display unit can show various types of attribute information (device names, addresses, connection status) and can be controlled through different modes (normal display mode and input reception mode). This universal design allows a single integrated component to perform multiple functions, improving maintenance efficiency without proportionally increasing manufacturing complexity.
