Smart Fuse Identification and Sensing Against Misuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuses in vehicles are misused by replacing them with incorrect sizes or non-standard components, leading to thermal events and electrical failures.
Innovation Solution
Incorporating identification components, electrical sensors, and temperature sensors in fuses to communicate with a receiver and processing unit, which determines whether the fuse is undersized, oversized, or non-standard, and triggers warnings or power cuts to prevent misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fuses are replaced by wrong fuse size or type, or by non-fuse components, then ease of operation is improved (easy replacement), but reliability deteriorates (thermal events and electrical failures)
Solution Approach 1:
The system performs preliminary verification by reading the identification component of the fuse before allowing operation. The processing unit checks whether the fuse specifications match the required parameters, and only authorizes operation after successful verification. This prevents misuse before it can cause harm.
Solution Approach 2:
The system provides immediate feedback through visual indicators (LED lights) and audio signals (buzzer) when a fuse is incorrectly installed. The receiver unit communicates the verification result to the user, allowing corrective action before thermal events or electrical failures occur.
2Reliability
If identification components and sensors are added to fuses, then reliability is improved (misuse detection), but device complexity increases
Solution Approach 1:
The identification component is integrated into the fuse itself, while the complex processing and verification logic is extracted into a separate receiver unit and control unit. This separation allows the fuse to remain simple while the verification system handles the complexity of misuse detection.
Solution Approach 2:
The receiver unit serves multiple functions: it reads identification information from the fuse, verifies specifications, provides visual and audio feedback, and controls power supply. This multi-functionality reduces the need for separate components for each function.
