Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator system owners or operators face challenges in accessing and resetting power to devices integrated with external systems, such as Destination Guidance Displays or Media screens, due to lack of remote control means and communication issues, especially when these devices are installed by third-party vendors.
Innovation Solution
A power reset arrangement and method utilizing a power reset unit with a wireless communication device, allowing a user to control power interruption and restoration to devices integrated with external systems via a wireless connection, using technologies like Bluetooth, Near-field communication, or audio signals, and requiring authentication keys for authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device is integrated into an external system, then the device can be installed in various locations and systems, but the elevator system operator cannot easily access the power supply to perform power reset
Solution Approach 1:
The patent introduces a wireless communication device as an intermediary between the user and the power reset function. This mediator enables remote control of the power reset without requiring physical access to the device or external system, thus resolving the contradiction between integration versatility and operational accessibility
Solution Approach 2:
The patent replaces the mechanical approach of physically accessing and switching power with a wireless communication-based control system. The power reset is triggered remotely via wireless signals, eliminating the need for physical access to the power supply while maintaining the integration capability with external systems
2Ease of operation
If remote control means are implemented, then power reset can be performed remotely, but the device complexity increases
Solution Approach 1:
The wireless communication device is designed to perform multiple functions including receiving reset commands, authentication, and communication with various user devices. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving remote power reset capability
Solution Approach 2:
The system includes authentication mechanisms that allow authorized users to perform power reset independently without requiring intervention from third-party vendors or system administrators. The device serves itself by providing the necessary control interface and security validation internally
