Solution Overview

Problem

Battery powered grease guns require users to operate the device with one hand, leaving no hands free for stabilization, especially when reaching difficult or hard-to-balance areas, limiting their effectiveness in applying grease efficiently.

Innovation Solution

A grease gun applicator system comprising a powered grease gun, a dispensing hose, a dispensing nozzle with a control switch, and a sling for easy transportation, allowing the user to operate the device with one hand by using a control switch to activate the motor and freeing up the other hand for stabilization and direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a battery powered grease gun is operated with one hand, then the other hand is freed for stabilization, but the user cannot properly direct the hose onto hard-to-reach areas

Engineering Contradiction:
Improvehand freedom for stabilizationVSAvoid hose direction control
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system separates the control function from the hose handling function by introducing a remote control switch. The main body handles grease dispensing while the remote switch handles activation, dividing tasks between different components to improve operational ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A remote control switch acts as an intermediary between the user and the grease gun motor. This mediator allows the user to activate the grease gun from a distance, freeing both hands for hose direction and stabilization without requiring direct hand operation of the trigger.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the hose length is kept short, then the grease gun remains compact and manageable, but the user must get very close to the area being greased

Engineering Contradiction:
Improvegun compactnessVSAvoidreach distance
Core Design Contradiction:
Device complexityVSLength of moving object

Solution Approach 1:

The system extends the operational reach by adding temporal control separation. The remote switch allows activation from a distance, effectively extending the functional length of the system in the spatial dimension without requiring a physically longer hose, maintaining compactness while increasing reach.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If manual pumping is required, then the grease gun can be simple and reliable, but both hands are occupied and no hands are free for stabilization

Engineering Contradiction:
Improvemechanism simplicityVSAvoidhand availability
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The manual pumping mechanical system is replaced with an electric motor-driven system. This substitution eliminates the need for hand pumping while providing powered grease delivery, freeing both hands for stabilization and positioning tasks.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electric motor performs the pumping function automatically without requiring manual intervention. The system serves itself by using electrical power to drive the grease delivery mechanism, eliminating the need for user pumping actions.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If a control switch is attached to the dispensing nozzle, then one-hand operation is enabled, but the device structure becomes more complex

Engineering Contradiction:
Improveone-hand operation capabilityVSAvoidcontrol system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The remote control switch serves as a separate intermediary component rather than being integrated into the main gun body. This modular approach enables one-hand operation while keeping the added structural complexity isolated to a small, detachable remote control unit.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A grease gun applicator system for making it easier to use a battery powered grease gun by freeing up one hand while greasing. The grease gun applicator system includes a powered grease gun, a dispensing hose extending from the powered grease gun, a dispensing nozzle attached to a distal end of the dispensing hose and a control switch attached to or adjacent to the dispensing nozzle to control the powered grease gun. A sling is preferably attached to the powered grease gun for allowing easy transportation of the powered grease gun.
