Solution Overview

Problem

Conventional spray reservoirs are either reusable and require time-consuming cleaning or use collapsible liners that are difficult to install and remove, and often result in leftover paint being difficult to recover and dispose of safely.

Innovation Solution

A disposable reservoir with a removable lid and integrated threads for secure sealing, allowing for easy mixing and storage of liquids, and compatibility with various spray gun apparatuses through adapters with internal or external threads, facilitating easy installation and disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a reusable rigid reservoir is used, then the reservoir can be used multiple times, but it requires time-consuming cleaning to prevent contamination

Engineering Contradiction:
ImprovereusabilityVSAvoidcleaning time
Core Design Contradiction:
Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The patent employs a disposable reservoir that is discarded after a single use, eliminating the need for cleaning while maintaining reusability benefits through continuous availability of fresh reservoirs. The reservoir is designed to be inexpensive enough to justify single-use disposal, solving the contradiction between reusability and cleaning time.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Loss of time

If a collapsible liner is used within a rigid reservoir, then cleaning frequency is reduced, but the liner is difficult to install and remove

Engineering Contradiction:
Improvecleaning frequencyVSAvoidliner installation and removal
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The entire reservoir including the liner is designed as a disposable unit that is discarded after use, eliminating the complex installation and removal operations while maintaining the benefit of reduced cleaning frequency. The liner and reservoir are manufactured as an integrated disposable component.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Loss of time

If a collapsible liner is used, then the rigid reservoir does not need frequent cleaning, but leftover paint is difficult to recover

Engineering Contradiction:
Improvecleaning frequencyVSAvoidleftover paint recovery
Core Design Contradiction:
Loss of timeVSLoss of substance

Solution Approach 1:

The disposable reservoir design accepts that some paint will remain in the discarded unit, eliminating the need for complex recovery systems. The economic design allows for minimal paint recovery while maintaining overall cost-effectiveness through elimination of cleaning and recovery operations.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If integrated threads are added for secure sealing, then sealing reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesealing reliabilityVSAvoidthread integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The threads are integrated directly into the reservoir body as a unified component rather than being separate parts, merging the sealing function into the basic reservoir structure. This reduces overall device complexity while maintaining reliable sealing through the integrated thread design.

Inventive Principle:
Principle #5Merging (Combining)
