Solution Overview

Problem

Current vehicle battery jump starters face limitations in voltage, power source, sparking, short circuiting, and electrical current magnitude, making them less versatile and effective, especially when AC mains power is not available.

Innovation Solution

A vehicle battery jump starter powered by a removable and rechargeable battery pack, which includes a controller, a battery pack interface, and a power boost module. The system charges the power boost module using the battery pack and controls the discharge current to maintain the battery pack voltage above a threshold, allowing for sufficient current to jump start a vehicle battery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional jump starter with internal power source is used, then the device can jump start a vehicle battery, but the device lacks versatility when AC mains power is not available

Engineering Contradiction:
ImproveversatilityVSAvoidreliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The jump starter is designed to accept multiple power sources including AC mains power, removable rechargeable battery packs, and depleted vehicle batteries. The system can charge the power boost module from any of these sources, making the device universally applicable in various power availability scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables the depleted vehicle battery to charge the power boost module directly, allowing the vehicle battery to serve its own recharging needs. This self-service capability eliminates the need for external power sources in some scenarios.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If a battery pack for power tools is used to power the jump starter, then the jump starter can be used anywhere with a battery pack, but the battery pack current magnitude is insufficient to jump start the vehicle battery directly

Engineering Contradiction:
ImproveportabilityVSAvoidcurrent magnitude
Core Design Contradiction:
Adaptability or versatilityVSPower

Solution Approach 1:

The power boost module acts as an intermediary energy storage device between the battery pack and the vehicle battery. The battery pack charges the power boost module, which then provides the high current needed to jump start the vehicle battery, bridging the gap between low-power and high-power requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The battery pack is used to pre-charge the power boost module before the jump starting operation. This preliminary charging action stores energy in the power boost module, preparing it to deliver the necessary current surge when needed.

Inventive Principle:
Principle #10Preliminary action

3Power

If the battery pack discharge current is increased to jump start the vehicle battery directly, then the jump starting capability is achieved, but the battery pack voltage drops below the allowable threshold

Engineering Contradiction:
Improvecurrent outputVSAvoidvoltage stability
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The power boost module serves as a buffer that decouples the battery pack from the high-current demand of the vehicle battery. It absorbs the current surge requirements, allowing the battery pack to discharge at controlled rates that maintain voltage above threshold levels.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The power boost module is charged in advance by the battery pack at controlled rates, storing energy before the high-current discharge is needed. This preliminary energy transfer prevents voltage collapse during the actual jump starting operation.

Inventive Principle:
Principle #10Preliminary action
