Portable Appliance Panel for Identifying Abnormal Wireless Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In manufacturing and distribution facilities, maintenance personnel face difficulties in identifying which device an operation panel is connected to, especially when multiple devices are connected via wireless communication, hindering efficient maintenance operations.
Innovation Solution
An appliance management system that includes sensors in each appliance to detect abnormalities and broadcast an identifier, and a portable terminal with near field wireless communication modules to connect with the appliances, allowing for the transmission of access requests and display of abnormality information, enabling the maintenance personnel to identify and address issues effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an operation panel is connected to multiple devices via wireless communication, then the operation panel can be flexibly used across different devices, but it becomes difficult to identify which device the operation panel is currently connected to
Solution Approach 1:
The patent uses visual display of device identifiers (such as device names, addresses, or icons) on the operation panel to indicate which device is currently connected. This visual feedback mechanism allows maintenance personnel to quickly identify the connected device without confusion, resolving the information loss problem while preserving wireless connectivity flexibility.
2Productivity
If the operation panel is oriented for operational efficiency, then the operation can be performed efficiently, but it becomes difficult for maintenance personnel to perform maintenance operations
Solution Approach 1:
The operation panel is designed to be detachable and repositionable, allowing it to be oriented optimally for operation during normal use and then moved or repositioned to provide access to maintenance areas when needed. This dynamic reconfiguration capability resolves the contradiction between operational efficiency and maintenance accessibility.
3Reliability
If maintenance personnel need to identify abnormal appliances among multiple devices, then timely maintenance can be performed, but the time required to locate and identify the specific abnormal device increases
Solution Approach 1:
The system provides immediate visual feedback by displaying the identifier of the abnormal appliance on the operation panel when connected via wireless communication. This feedback mechanism allows maintenance personnel to quickly identify which specific device is abnormal without having to manually check each device, significantly reducing the time to locate and respond to abnormalities while maintaining system reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient maintenance by allowing maintenance personnel to quickly identify and respond to abnormalities in appliances through the display of relevant information on the portable terminal, ensuring timely intervention and reducing downtime.
Implementation Method 1
a first near field wireless communication module configured to broadcast an identifier of the appliance

AI summary
An appliance management system includes a plurality of appliances connected to a network and a portable terminal. Each of the appliances includes a sensor configured to detect an abnormality of the appliance, and a first near field wireless communication module configured to broadcast an identifier of the appliance when the sensor detects the abnormality. The portable terminal includes a second near field wireless communication module and a controller. The controller is configured to control the second near field wireless communication module to transmit an access request to an abnormal appliance upon the second near field wireless communication module receiving an identifier of the abnormal appliance. The terminal controller is also configured to control a display to display an abnormality screen including the identifier of the abnormal appliance upon the second near field wireless communication module receiving abnormality information from the abnormal appliance.
