Solution Overview

Problem

Existing machines lack the ability to efficiently utilize their electrical and hydraulic systems for performing additional tasks beyond their primary functions, leading to increased operational costs due to the need for additional equipment and reduced productivity.

Innovation Solution

An accessory attachment system that includes a housing detachably coupled to the machine, with electric and fluid connectors allowing for the selective power supply to external devices, enabling the machine to power external electrical and hydraulic devices directly from its systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional equipment is arranged alongside the machine to perform extra tasks, then the machine can perform more functions, but the operational cost increases and the worksite requires more equipment maintenance

Engineering Contradiction:
ImprovefunctionalityVSAvoidequipment quantity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements an accessory attachment system with electric and hydraulic connectors that enable a single machine to perform multiple functions by powering external devices. The system allows the machine's electrical and hydraulic systems to serve both primary machine operations and additional external tasks simultaneously, eliminating the need for separate equipment.

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

2Productivity

If additional equipment is arranged alongside the machine to perform extra tasks, then the machine can perform more functions, but transporting and maintaining this equipment increases operational cost

Engineering Contradiction:
Improvetask capacityVSAvoidoperational cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent merges the functionality of multiple separate devices into a single integrated attachment system. By combining electric connectors, hydraulic connectors, and mounting mechanisms into one accessory attachment system, the machine can perform multiple tasks using a single integrated unit rather than multiple separate devices, reducing transportation and maintenance costs.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the power source is used to propel the machine and drive predefined implements, then the machine performs its primary functions, but it cannot directly power additional tasks requiring external equipment

Engineering Contradiction:
Improvetask varietyVSAvoidpower usability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary accessory attachment system that acts as a bridge between the machine's power source and external devices. The electric and hydraulic connectors serve as intermediaries, transferring power from the machine's systems to external equipment, enabling the power source to directly support additional tasks without requiring separate power sources.

Inventive Principle:
Principle #24Intermediary (Mediator)
