Innovation Solution
A wireless jumper system that includes a mobile device, server, and a jumper with a processor, memory, GPS, and networking device, allowing remote activation/deactivation and automatic logging, with alerts and timers to ensure safe disconnection and prevent accidental leaving behind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional paper logs are used to track jumper usage, then the system is simple and easy to implement, but the tracking efficiency is low and human error is high
Solution Approach 1:
The patent replaces the mechanical paper-based logging system with an electronic automated tracking system. The jumper device includes a processor that automatically logs usage data, connection events, and disconnection events to digital memory, eliminating manual paper recording and significantly improving tracking efficiency while reducing human error.
Solution Approach 2:
The jumper device performs self-monitoring and self-logging of its usage status. The processor automatically tracks when the jumper is connected to terminals, maintains usage logs, and manages its own operational data without requiring external manual intervention, thereby improving productivity while keeping the system relatively simple.
2Reliability
If no automated warning system is implemented, then the system is simple, but service technicians may inadvertently leave jumpers connected causing safety hazards
Solution Approach 1:
The patent implements a feedback mechanism where the processor continuously monitors the jumper's connection status and provides automated warnings to service technicians. When the jumper remains connected beyond the expected maintenance window or when disconnection is detected, the system generates alerts to notify technicians, improving safety through automated feedback loops.
Solution Approach 2:
The system performs preliminary actions by setting expected maintenance windows and proactively monitoring for abnormal situations before safety hazards can occur. The processor anticipates when the jumper should be removed and prepares warnings in advance, preventing potential accidents rather than reacting to them after they occur.
3Measurement precision
If manual tracking of jumper disconnection is used, then the system is simple to operate, but the accuracy of tracking is low and time-consuming
Solution Approach 1:
The patent replaces manual tracking methods with automated electronic monitoring. The processor continuously and automatically detects connection and disconnection events, precisely recording timestamps and usage duration without human intervention, thereby achieving high tracking accuracy while eliminating the time required for manual recording and verification.
4Productivity
If jumpers are left connected during maintenance, then the maintenance process is simple and quick, but safety accidents may occur
Solution Approach 1:
The system maintains high maintenance efficiency while preventing safety hazards through automated feedback mechanisms. The processor monitors jumper connection status in real-time and provides immediate warnings if the jumper is left connected after maintenance completion, allowing technicians to work efficiently without compromising safety through automated oversight.
Solution Approach 2:
The automated warning system acts as an intermediary between the jumper device and the service technician. It mediates the maintenance process by providing objective safety information and reminders, enabling technicians to maintain high productivity while ensuring safety protocols are followed through the intermediary's automated monitoring and alerting functions.
Data Source
AI summary
A jumper has a connector and a housing. The housing at least partially encloses a processor in data communication with a non-transitory memory, a global positioning system, a rechargeable battery, and a networking device. The memory comprises software instructions that, when executed by the processor, perform steps for wirelessly transmitting data to a mobile device over a network. The data indicates a jumper identification number, a location of the jumper, and a duration after which the jumper will automatically deactivate. The steps performed include the step of wirelessly outputting an alert to the mobile device when the mobile device is at a first distance from the jumper. The first distance is settable using the mobile device. The alert causes the mobile device to at least one of vibrate and ring.
