Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic badges in the prior art suffer from high power consumption leading to short standby times and poor user experience.
Innovation Solution
An electronic badge system with a control module that determines its location using RFID modules and actuators, switching to a non-working state when outside the workplace to conserve power, and employing passive RFID modules and intermittent data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic badge continuously transmits data and maintains active tracking mode, then the positioning accuracy and data availability are improved, but the power consumption increases and standby time decreases
Solution Approach 1:
The electronic badge implements periodic transmission of identification information only when active tracking mode is enabled, rather than continuous transmission. The system periodically checks whether transmitters/receivers are in the tracked area and only then activates transmission, significantly reducing power consumption while maintaining positioning accuracy when needed.
Solution Approach 2:
The badge dynamically switches between active tracking mode and standby mode based on whether transmitters/receivers are detected in the tracked area. This dynamic adjustment of operational state allows the system to maintain positioning accuracy when required while minimizing power consumption during normal standby operations.
2Loss of time
If the electronic badge maintains continuous working state for real-time positioning, then the responsiveness and data freshness are improved, but the battery life and user experience deteriorate
Solution Approach 1:
The system uses periodic detection to determine if transmitters/receivers are present in the tracked area, and only activates active tracking mode when detected. This periodic check mechanism ensures quick response when entering the tracked area while extending standby time during normal operations outside the tracked area.
Solution Approach 2:
The electronic badge automatically switches between working and standby modes based on its own detection of transmitters/receivers in the tracked area, without requiring external control. This self-service mechanism optimizes the balance between response time and standby time autonomously.
3Speed
If the electronic badge uses active radio transmitters for positioning, then the transmission range and signal strength are improved, but the power consumption increases
Solution Approach 1:
The active radio transmitters are activated only periodically when transmitters/receivers are detected in the tracked area, rather than continuously. This periodic activation maintains signal transmission capability when needed while dramatically reducing overall power consumption during standby mode.
Solution Approach 2:
The radio transmitter dynamically adjusts its operational state between active and standby modes based on the presence of transmitters/receivers in the tracked area. This dynamic control allows the system to maintain fast signal transmission when required while minimizing energy consumption during normal operations.
