Solution Overview

Problem

Existing welder systems are limited by the need for specific electrical power sources, making them inflexible and difficult to use in field environments where access to AC or DC power is restricted, and PTO systems on work trucks are constrained by space, torque, and angular velocity, limiting the versatility of auxiliary machines they can power.

Innovation Solution

A multi-component auxiliary power system that integrates a power transfer linkage with an air compressor, electric generator, and hydraulic pump, all mechanically linked to a single prime mover, allowing for flexible distribution of rotational power to various machines, including compressed air, hydraulic, and electric power sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If a single PTO drive is used to power auxiliary machines, then weight is reduced and space is optimized, but the versatility to power different types of machines with different power requirements is limited

Engineering Contradiction:
Improvetruck weightVSAvoidpower distribution flexibility
Core Design Contradiction:
Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

The power transfer linkage is designed with multiple rotational power outputs that can simultaneously or selectively power different types of auxiliary machines (compressors, hydraulic pumps, electric generators) with different power requirements, making the single PTO drive universally applicable to various machine types without requiring multiple separate power sources

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

Solution Approach 2:

The power transfer linkage segments the single PTO drive's rotational power into multiple independent power outputs, allowing each auxiliary machine to receive appropriate power independently while maintaining overall system versatility and reducing total system weight compared to using separate power sources for each machine

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple separate power sources are integrated onto the truck, then versatility and functionality are enhanced, but weight increases and space efficiency decreases

Engineering Contradiction:
Improveauxiliary power functionalityVSAvoidtruck weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

Multiple auxiliary power components (compressors, hydraulic pumps, electric generators) that would traditionally require separate power sources are merged into a single integrated system powered by one PTO drive through the power transfer linkage, reducing total weight while maintaining full functionality of all auxiliary machines

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the PTO system operates within strict constraints of space, torque, and angular velocity, then the transmission design is simplified, but the flexibility to power different types and numbers of machines is limited

Engineering Contradiction:
Improvetransmission designVSAvoidmachine configuration flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The power transfer linkage incorporates dynamic elements including variable gear ratios and adjustable torque distribution mechanisms that allow the system to adapt to different machine configurations and power requirements while operating within the fixed constraints of the PTO drive's space, torque, and angular velocity limitations

Inventive Principle:
Principle #15Dynamics
