Solution Overview

Problem

Conventional power generation systems in recreational vehicles operate at a fixed load voltage, leading to reduced power output at low and high engine speeds, compromising between engine starting and high-speed power needs, and often result in overheating and insufficient battery charging, especially during manual start systems and plow operations.

Innovation Solution

A power boost regulator utilizing low loss field effect transistors (FETs) for switching transformations, allowing load-matched voltage operation across the entire RPM range, thereby increasing power output without altering the stator or flywheel, and prioritizing power distribution to critical loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed load voltage is used throughout the RPM range, then the charging system can operate at a selected voltage, but power output is reduced at low and high engine speeds and the system must compromise between starting power and high-speed power needs

Engineering Contradiction:
Improvefixed voltage operationVSAvoidpower output
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The patent implements dynamic voltage regulation by allowing the load voltage to vary with engine speed. The regulator adjusts the voltage according to the RPM range: lower voltages at low speeds and higher voltages at high speeds, transforming the fixed voltage system into a dynamic one that adapts to operating conditions to maximize power output across the entire RPM range

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the voltage parameter dynamically based on engine speed. By modifying the operating voltage as a variable parameter rather than keeping it fixed, the system optimizes power delivery at different RPM levels, allowing higher power extraction at high speeds while maintaining adequate voltage at low speeds for starting

Inventive Principle:
Principle #35Parameter changes

2Power

If large currents are produced by the magneto to provide required vehicle power at fixed load voltage, then power needs are met, but air-cooled engines are prone to overheating

Engineering Contradiction:
Improvevehicle powerVSAvoidengine temperature
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

The patent reduces temperature by changing the voltage parameter to match load requirements. At high power demands, the regulator increases voltage, which reduces the current required to deliver the same power (P=VI). This parameter change lowers I²R losses and heat generation in the magneto and wiring, preventing overheating while maintaining adequate power delivery

Inventive Principle:
Principle #35Parameter changes

3Power

If magneto size is scaled to meet increasing electrical power demands, then power output increases, but cost increases

Engineering Contradiction:
Improveelectrical power outputVSAvoidcost
Core Design Contradiction:
PowerVSEase of manufacture

Solution Approach 1:

The patent extracts additional power from the existing magneto by changing the operating voltage parameter dynamically. Instead of scaling up the magneto size, the regulator optimizes the electrical parameters (voltage and current) to maximize power extraction from the current magneto, thereby increasing power output without increasing manufacturing cost

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by using the existing magneto capacity more efficiently through intelligent voltage regulation. Rather than installing a larger magneto, the system extracts more power from the current one by optimizing its operating parameters, achieving increased power output with only partial utilization enhancement of the existing component

Inventive Principle:
Principle #16Partial or excessive action

4Ease of operation

If fixed load voltage is used, then system operation is simplified, but battery charge level is not sufficiently maintained during high-demand operations like plowing

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements dynamic voltage regulation that responds to battery charge needs. During high-demand operations, the regulator increases voltage to maximize charging current to the battery, ensuring adequate charge maintenance. This dynamic adjustment maintains reliability without complicating system operation, as the voltage changes are automatic and transparent to the operator

Inventive Principle:
Principle #15Dynamics
