Smart Jumper Cable with Voltage Display Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jumper cables lack the ability to assess the condition of a vehicle battery, as they do not include a display module to indicate electrical parameters, making it difficult to determine if the battery is functioning properly.
Innovation Solution
A smart jumper cable with a display module, comprising clamps, a control module, and a voltage detection circuit, which uses an MCU, switch module, and display module to visually indicate the battery voltage, incorporating components like MOS transistors, resistors, and a nixie tube or LCD screen for clear voltage readings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a display module is added to the jumper cable, then the ability to detect and display battery voltage is improved, but the device complexity increases
Solution Approach 1:
The patent combines the display module, control module, and voltage detection circuit into an integrated assembly that is incorporated into the jumper cable handle. This merging approach allows the cable to gain voltage detection and display capabilities while maintaining a compact, unified structure rather than adding separate disconnected components.
Solution Approach 2:
The jumper cable is transformed from a simple power transfer device into a multi-functional tool that simultaneously performs power delivery and battery voltage detection. The display module enables the cable to serve as both a jumper starter and a diagnostic device, allowing users to check battery condition before attempting to start the vehicle.
2Adaptability or versatility
If a voltage detection circuit and display module are integrated into the jumper cable, then the functionality is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The voltage detection circuit is designed as a separate modular component that can be independently assembled and tested before integration into the final cable assembly. This segmentation allows manufacturers to produce the detection circuit and display module separately, then combine them with the cable components in a systematic assembly process, reducing overall manufacturing complexity.
