Mining Control Module Warning Device Segmented Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current warning devices in mining control modules require significant effort to replace, leading to substantial downtime of longwall systems due to the need to disassemble and reassemble soldered connections, which cannot be performed underground.
Innovation Solution
A warning device with a housing that couples to the control module's outer surface, featuring a releasable alarm module and fixation means, allowing for easy replacement without soldering, and enabling secure sealing to protect electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the warning device is soldered to the control module to ensure secure connection and sealing, then the reliability and sealing are improved, but the replacement time and complexity increase significantly
Solution Approach 1:
The housing is divided into a first portion that extends through the opening and a second portion that covers the opening, allowing the warning device to be segmented for easier installation and replacement while maintaining sealing integrity
Solution Approach 2:
The alarm module is extracted as a separate, releasably coupled component from the housing, enabling the warning device to be replaced without soldering or complex disassembly, thus reducing replacement time while maintaining reliable connection
2Strength
If the warning device is soldered to the control module to provide structural resistance, then the strength and durability are improved, but the ease of repair and replacement deteriorate
Solution Approach 1:
The fixation means is designed to releasably engage the outer surface before the alarm module is installed, pre-establishing a secure mechanical connection that provides structural resistance while allowing future easy removal and replacement
Solution Approach 2:
The soldering process is replaced with a mechanical fixation system comprising the housing portions and fixation means, which provides comparable or superior structural resistance while enabling tool-free or simple tool-assisted replacement
3Reliability
If the connection is made in the interior of the control module to ensure secure integration, then the reliability is improved, but the accessibility for maintenance deteriorates
Solution Approach 1:
The first portion of the housing acts as an intermediary element that extends through the opening to provide electrical and mechanical connection, while the second portion with fixation means provides external accessibility, allowing maintenance without opening the control module

AI summary
The present invention relates to a warning device for a mining control module for facilitating a replacement. Accordingly,, a warning device for a mining control module is suggested, which comprises a housing that is configured to be coupled with an opening provided at an outer surface of the control module, wherein the housing defines an inner cavity, and an alarm module which is arranged in said cavity and is configured to be releasably coupled to an inner control unit of the control module via said opening for receiving a control signal. The housing comprises a first portion that extends along a longitudinal axis and is configured to extend at least in part through the opening and a radially extending second portion that is configured to extend over the outer surface of the control module so as to cover the opening, when the device is coupled to the control module. The device furthermore comprises a fixation means, which is arranged on the second portion and is configured to releasably engage the outer surface of the control module so as to secure the device to the control module.
