Solution Overview

Problem

Vehicles often experience 'dead' battery states due to insufficient charging, self-discharge, cold weather, or aging, leading to stranded situations as legacy remedies like jump-starting are not readily available.

Innovation Solution

An auxiliary power system is designed to be mounted within a vehicle, featuring an auxiliary battery and circuitry that detects trigger events to provide power to the starter circuit, including a manual switch, automatic detection of a failing start, or remote activation, to assist in starting the engine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the battery is used to power auxiliary features while the engine is off, then the battery may enter a 'dead' battery state, but the vehicle cannot be started

Engineering Contradiction:
Improveavailability of vehicle starting capabilityVSAvoidbattery charge level
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The power system is divided into two separate batteries: a starter battery dedicated to engine starting and an auxiliary battery dedicated to powering features when the engine is off. This segmentation prevents the auxiliary battery from depleting the starter battery, ensuring the vehicle can always be started regardless of auxiliary power consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A controller acts as an intermediary between the two batteries, managing power flow and determining when to draw from each battery. The controller monitors charge levels and automatically switches between batteries or charges the auxiliary battery from the starter battery, preventing the starter battery from entering a dead state.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If legacy remedies like jump-starting are used, then the vehicle can be started, but external assistance is required and waiting time increases

Engineering Contradiction:
Improvevehicle starting speedVSAvoidindependence from external assistance
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary charging of the auxiliary battery from the starter battery when the engine is running and the alternator is charging. This preliminary action ensures the auxiliary battery is ready to take over auxiliary power demands, preventing future dead battery situations and eliminating the need for external jump-starting assistance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The dual battery system with automatic controller enables the vehicle to self-manage its power needs. The system automatically charges the auxiliary battery, monitors charge levels, and switches between batteries as needed, making the vehicle independent from external assistance for starting problems.

Inventive Principle:
Principle #25Self-service

3Device complexity

If a single battery is used for both starting and auxiliary power, then the system is simpler, but the battery charge level becomes insufficient for starting

Engineering Contradiction:
Improvepower system structureVSAvoidstarting capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The power system is divided into two separate batteries: a starter battery dedicated to engine starting and an auxiliary battery dedicated to powering features when the engine is off. This segmentation prevents the auxiliary battery from depleting the starter battery, ensuring the vehicle can always be started regardless of auxiliary power consumption.

Inventive Principle:
Principle #1Segmentation
