Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable vehicle jump-starting devices face challenges in maximizing conductivity between the lithium ion battery pack and the vehicle battery, which is crucial for successful jump-starts, especially for big engines, as both power and conductivity are necessary but often not adequately optimized in current designs.
Innovation Solution
A rechargeable battery assembly with a lithium ion battery pack, enhanced positive and negative terminal conductor bars, and a smart switch interface with relays, along with improved cable connections and diode configurations, are used to increase conductivity and power delivery, including increasing wire gauge, optimizing cable connections, and redesigning the diode printed circuit board.

Engineering Contradiction Analysis
1Reliability
If conventional battery connections are used in jump starting devices, then the device structure remains simple, but the conductivity between the battery pack and vehicle battery is insufficient for successful jump-starts of big engines
Solution Approach 1:
The battery connection system is segmented into multiple conductor bars (positive and negative) with separate connection points on the battery cells. This segmentation allows for optimized electrical pathways and improved conductivity while maintaining manageable structural complexity through modular arrangement.
Solution Approach 2:
The patent introduces a three-dimensional conductor bar structure that extends in multiple directions from the battery terminals. The conductor bars are positioned at different spatial locations and angles to maximize electrical contact and conductivity, transforming a simple linear connection into a multi-dimensional conductive network.
2Power
If wire gauge is increased to improve conductivity, then power delivery capability is enhanced, but the device becomes more complex and harder to manufacture
Solution Approach 1:
Multiple conductor bars are merged into a unified connection system that shares common mounting structures and battery cell connection points. This merging approach allows the system to achieve high power delivery through combined conductivity while simplifying manufacturing by reducing the number of separate mounting operations and fasteners required.
Solution Approach 2:
The patent optimizes the conductor bar dimensions, materials, and cross-sectional areas to achieve the desired power delivery capability. By carefully selecting conductor parameters (thickness, length, material composition) and optimizing their geometric configuration, the system achieves high power transmission without requiring excessively large or complex structures that would difficult to manufacture.
