Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in electric rooms often face electric shock accidents due to careless handling of high-voltage equipment, as existing safety methods rely on attention-based warnings and lack real-time monitoring and automatic protection measures, especially in large distribution boards where communication between operators is inadequate.
Innovation Solution
A wearable device that monitors bioelectric currents and classifies hazard levels, providing visual and auditory warnings, transmitting alerts to nearby devices, and automatically cutting off power when high-risk currents are detected, ensuring operators and nearby coworkers are informed and protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators perform power cut-off operations and safety procedures, then electric shock accidents are prevented, but work time is extended and productivity decreases
Solution Approach 1:
The wearable device performs preliminary detection of bioelectric currents and automatically triggers warning signals or power cut-off before actual electric shock occurs. This advance warning system allows operators to prepare for safety procedures without unnecessary delays, as the system proactively identifies hazardous situations and initiates protective actions before contact with live electricity happens.
Solution Approach 2:
The safety system operates autonomously by continuously monitoring bioelectric currents and automatically executing warning or power cut-off functions without requiring constant operator intervention. The wearable device self-regulates safety protocols based on real-time current detection, reducing the time operators need to spend on manual safety checks while maintaining high reliability.
2Productivity
If operators ignore safety regulations to quickly check distribution board failures, then productivity increases, but electric shock accidents frequently occur
Solution Approach 1:
The wearable device provides real-time feedback to operators through warning signals when bioelectric currents indicate potential electric shock hazards. This continuous feedback loop allows operators to maintain quick repair operations while being alerted to dangerous conditions, enabling them to balance speed with safety by responding to warnings rather than ignoring them.
Solution Approach 2:
The system monitors changes in bioelectric current parameters and triggers appropriate safety responses based on detected current levels. By dynamically adjusting safety protocols according to real-time current measurements, the system allows rapid repair operations when safe but automatically intervenes when current parameters indicate hazardous conditions, preventing accidents without unnecessarily slowing down legitimate work.
3Productivity
If operators work in large distribution boards without adequate communication, then productivity increases, but safety monitoring becomes insufficient
Solution Approach 1:
Each operator wears a standalone wearable device that independently monitors their own bioelectric currents and provides personal safety warnings. This self-service approach eliminates the need for operators to constantly communicate with each other or supervisors, as each device autonomously detects and warns of hazards specific to that operator's immediate environment, maintaining both productivity and safety monitoring.
Solution Approach 2:
The wearable device provides localized safety monitoring focused on the specific operator's body and immediate surroundings, rather than requiring comprehensive team-wide communication. Each operator receives personalized real-time warnings based on their individual bioelectric current measurements, enabling safe operation in large distribution boards without needing constant group coordination.
