Disposable Spray Reservoir with Integrated Threads
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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
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.
4Reliability
If integrated threads are added for secure sealing, then sealing reliability is improved, but device complexity increases
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.
