Solution Overview

Problem

Existing transportable paint sprayers require users to either carry the weight of the paint reservoir or the base device while working, which is inconvenient, especially when using a ladder.

Innovation Solution

A transportable paint sprayer design featuring a base station with a drive unit and a tube-like lance connected via air and paint lines, allowing the user to control the spray head and base station from a single position without needing to move, with adjustable airflow and paint flow settings for optimal operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the paint reservoir is attached directly to the spray device or conveyed via a separately operated device, then the paint can be supplied to the spray device, but the user has to move the weight of the paint or carry the base device, which is inconvenient especially when working on a ladder

Engineering Contradiction:
ImproveEase of operationVSAvoidWeight of paint
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The heavy paint reservoir is extracted from the portable spray device and placed in a stationary container at the base station. Only the lightweight spray gun and lance need to be carried by the user, while the paint is conveyed through a flexible hose to the working position.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A flexible paint hose acts as an intermediary between the stationary paint reservoir and the portable spray gun. This allows the paint to be conveyed to the user's working position without the user having to carry the heavy reservoir, enabling operation from a fixed base station.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the user controls the spray head and base station from different positions, then each component can be operated independently, but the user has to move between positions which reduces efficiency

Engineering Contradiction:
ImproveProductivityVSAvoidEase of operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The control functions for both the spray head and the base station are merged into a single integrated control unit. This allows the user to operate both components from one position, improving efficiency and eliminating the need to move between separate control points.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control unit is designed with multi-functionality, serving as both the spray trigger mechanism and the controller for the base station pump and airflow. This universal control interface allows the user to manage all aspects of the spray system from a single location.

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