RIMOSA Museum Inflation Table

Exhibit Design & Engineered Build Plan, 2020

Inflation Table Exhibit

As a new exhibit for the Rhode Island Museum of Science and Art (RIMOSA), The Inflation Table features an open ended experience for the user: it encourages curiosity, playfulness, and physical interaction. I developed and pitched the concept, sketched, modeled, prototyped, and engineered the design and then made a detailed build plan & materials spreadsheet.

How it Works:

The exhibit features 13 bags and two pumps, a tubing network connects each bag to a pump, and rotating disc with cutouts determines which bags inflate. The disc adds ‘randomness’ to the inflation system. There is a prize wheel stopper system installed under the disc to ensure that it will not spin for too long. With planned bag layout and disc cutouts, the user can expect a minimum of one and a maximum of three bags per pump will inflate at every disc position. 

Example Scenarios:

  • Disc is spun and stopped. The disc allows air to flow into 3 bags connected to pump one, and 1 bag from pump two.

  • Disc is spun and stopped. The disc allows air to flow into 2 bags connected to pump one, and 2 bags from pump two.

 

Final Deliverable:

Because this internship was remote, I did not construct the exhibit. Instead I created a detailed build plan and a materials spreadsheet. These can be followed to build the exhibit: Link to Build Plan, Link to Materials Spreadsheet

 

Design Process:

Project Description: I was tasked with designing a new exhibit for The Rhode Island Museum of Science and Art. The non-profit organization aims to foster the traits that artists and scientists share: curiosity, observation, experimentation, and communication. At RIMOSA people explore open-ended, hands-on exhibits and activities.

Design Criteria: All exhibits and programs must be hands-on, open-ended, and catalysts for future learning.

  1. Hands-on: physically interactive, requiring either gross or fine muscle involvement 

  2. Open-ended: no one right answer or even a specific end 

  3. Catalysts for Future Learning: designed so that their method of construction is visible

RIMOSA prefers exhibits that involve everyday items. This empowers users to see how they could make something similar.

Inspiration: When researching and brainstorming, I found Nils Völker. His project, “One Hundred And Eight” is an interactive installation that acts like a breathing wall. I enjoyed the experience of watching the bags inflate and deflate and used this as a starting point for my design. Link to Völker’s work

Brainstorming and Experiments: I began by working with inflation techniques, using materials found around my house.

Not enough air in the pump to inflate the bag in one motion
Pipe too narrow for efficient air transfer
Both bags have the same volume, air flows easily
Top bag has a smaller volume than the pump, so top bag pops off occasionally

Insights: Following my experiments and interviews with RIMOSA's staff, I made design decisions for how the exhibit would function and integrate into RIMOSA’s collection. I focused on the exhibit’s size, ability to travel, where it could break, the interaction, and the STEAM Concept it would feature.

Concept Sketches: I drafted two designs based on my insights, and presented them to RIMOSA. They chose Design 2.

Prototypes: I prototyped the bearings, exhibit body, and disc-bag layout

Tested the spinning mechanism

Built a step pump, tested the tubing & prototyped the disc’s proportions

The disc layout above ensures that wherever the disc lands, at least one bag per pump will inflate. The combinations for each spin are shown by this chart.

Tubing: After deciding which bags connect to which pumps, I prototyped the tube layout to optimize the air from the pump. Three tubes will connect to each pump. Each tube is paired to 2 or 3 bags, only one of which will inflate at any disc position.

Takeaways & Conclusions

Throughout the design process my exhibit solutions were designed to met the criteria defined by RIMOSA’s design rubric: 

To make the exhibit hands-on... pumps are wide and long, encouraging users to jump/step on them, the spinning disc can spin freely but securely under various forces, and the plastic bags offer a unique tangible experience inflated or deflated 

To keep this exhibit open-ended... users can discover different disc spins and result in different inflations, they can make up their own games to play, or discover how it works, and there is no specific end to the interaction and no right answer

To ensure that this exhibit serves as a catalyst for future learning... four windows allow the user to peer into the inner workings of the exhibit, and it is built with easily identifiable parts, thus making it easier to comprehend and replicate

To make the exhibit maintainable and transportable... the plastic bags are easy to replace in the event that one is torn or popped, the volume of air in the system is open instead of air-tight, the pumps are easy to disconnect and reattach, and the RIMOSA logo clearly brands the exhibit for when it travels outside the museum space
