Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems cannot effectively check the function of detecting derailment of the elevating body without disconnecting it from the guide rail, making it difficult to perform operation tests.
Innovation Solution
An elevator system with a conductive wire along the guide rail, a contact attached to the elevating body, and an inspection contact on the conductive wire, allowing the control panel to detect electrical conduction between the contact and the inspection contact without physically disconnecting the elevating body, enabling the system to check derailment detection functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elevating body is disconnected from the guide rail to test derailment detection, then the detection function can be verified, but the system complexity and difficulty of operation increase
Solution Approach 1:
The patent introduces an inspection contact as an intermediary device that mediates between the contact on the elevating body and the conductive wire. This inspection contact can be manually positioned to simulate derailment conditions without actually disconnecting the elevating body from the guide rail, thereby verifying the detection function while maintaining normal installation conditions
Solution Approach 2:
The inspection contact is pre-positioned at a preset position along the conductive wire where it can make contact with the wire to simulate derailment. This preliminary positioning allows the test to be performed without needing to actually disconnect the elevating body during the test operation
2Reliability
If the elevating body is disconnected from the guide rail for testing, then derailment detection can be checked, but the time required for testing increases
Solution Approach 1:
The inspection contact is pre-installed and pre-positioned along the conductive wire at locations that correspond to potential derailment points. This preliminary setup allows testers to simply move the inspection contact to verify detection functionality without performing time-consuming disconnection operations
Solution Approach 2:
The inspection contact creates a simplified copy or simulation of the actual derailment condition. Instead of physically disconnecting the elevating body (the original complex operation), the inspection contact replicates the electrical contact scenario that would occur during actual derailment, enabling rapid verification

Function Achieved in This Case
Enables the checking of derailment detection functionality without disconnection, ensuring the system's operational integrity and preventing potential damage from arc occurrences during testing.
Implementation Method 1
a control panel electrically connected to the conductive wire and being configured to detect electrical conduction between the conductive wire and the contact
Implementation Method 2
an inspection contact having conductivity, the inspection contact being attached to a preset position of the conductive wire and disposed at a position that allows the inspection contact to come into contact with the contact in a case where the contact moves to the preset position
